Please Sabine, would you also make a video to the other modified gravity theories (if this is right), explaining the observation with Retardation or relativistic effects of the transportation of gravity effects (Authors like A. Yahalom). I don't understand the mathematics well enough myself to judge their value 🤔
@@Somebodyherefornow that is not quite true. First we never observed Dark Matter. It only seems the best explanation for what we observe. And second, everything that we observe which seems to follow some rules and laws, ideally being scientific should and can be described by a theory, which over time might get refined or even replaced by a more comprising theory. Would you agree on that?
The first story seems to be about my favorite trend in science: Making your results by altering your datasets. Makes understanding results very frustrating because you can't trust them without understanding something about data or method.
I don't think the point was about cherry-picking, more that the data might have by chance not been appropriate for demonstrating / refuting MOND. Also, I think Sabine is on the side of preferring MOND...I'm not saying she's not objective, but this isn't the channel where you're going to hear "MOND has been basically ruled out".
Cool to see the paper on Artificial Atoms with Scanning Tunneling Microscopy (STM) featured on this channel, which is my field of research! When Alex Khajetoorians presented these results at a conference a few months ago, we were all very impressed (or at least the few people in the room that do STM, which is how it always is). Many attempts have been made over the last 15 years to develop a platform for artificial molecules that is both versatile and scalable, and these Cesium atoms on Idium-tin seem really promising. The tool in the field is the STM, which is in essence a needle with an atomically sharp tip. Therefore, if you scan over an atom (on a flat surface) you have the spatial resolution to observe it. But an STM is more than just a microscope. It is also a tool for 'atom engineering': you can pick up an atom and drop them off at another place on the surface, all with atomic precision! This is why STM is such a great technique for molecule simulation. However, if you cannot practically scale up your atomic structure, you stay in the regime of trivial artificial molecules. I hope that the group in Nijmegen (Radboud University) is able to deliver on the potential. In the meantime, I'll stay working on my nice collection of magnetic atoms.
I was transfixed when I saw the electron getting agitated before the quantum jump to an higher level; similarly to when it returned to its original energy state. I always imagined the jump as an instantaneous transaction, not as a carefully choreographed interaction between photon and electron. Physics never cease to amaze me...
It's amazing tech but seems like it could be miniaturised into arrays some day. Imagine a tiny dot matrix printer head with electric pins (grid of electrified pins that can move up and down and change voltage). This could pick up multiple atoms and deposit them in a pattern. Maybe that phonon chip tech mentioned earlier could help. I could imagine this tech getting 1000s of times faster within 50 years. Could be useful to make chip die prototypes cheaply and rapidly at some point, even advanced, picometer chip fabs.
'Non-biased' is a bit much.. Less biased than many scientists and science journalists but still pretty biased. A good example of this vid was not questioning the Far Liberal Lefty propaganda surrounding the stupidly simplified climate change rating system and the throw away comment that translates as 'as if humans are going to simply follow advice', implying they need to be FORCED (by Fake-Green global and national institutions).. Funny, because when this was done manufacturing was rapidly moved from The West to The Rest who then rapidly tripled their populations from around 2 billion to around 6 billion in just 50 years while increasing pollution to many times pre 1980s levels... Uber-Green Regulation in The West acted as an excuse to hyper-pollute The Rest.

In order to compensate for mentioned gravitational effects on time the IEEE wanted to introduce a new time reference called Coordinated Universal Normalized Time, but they decided against it when they saw the acronym.
As someone who works in videogames, the micro robot "research" that you talked about just looks like the first draft of the AI I make before I work out the bugs
Good to hear there are at least some people in the video game industry that are interested in working out bugs instead of leaving it up to the player base. But yeah, when I looked at what those scientists were doing it seemed utterly elementary for anyone used to fooling around with graphics. Well, scientists need to publish papers and evidently one of the easiest ways to do that is take something simple, obfuscate it with big words, and paste it into a boilerplate scientific paper form.
@@marcelmolenaar5684 Virtual bugs don't need no Newton equations... Which, maybe ironically, is going to turn out to be one of the problems with AI. Or, maybe it will like what the cold virus did to the aliens from Mars in HG Wells War of the worlds?
The point of the research was to stick to limitations present in manufacturing microscopic bots. The way life makes things work is it exploits emergent behavior of the organic molecules wiggling about, and better understanding emergent properties of collections of simple machines could help with developing nanobots.
Spannender Vortrag zu evidenten u n t e r s c h i e d l i c h e n "E n t r o p i e n und E n t a l p i e n" bei verschiedenen eigentlich doch recht unterschiedlichen ähnlichen R e a k t i o n s - Abläufen.👍👍👍 E n t r o p i e beschreibt die "innere Energie" in einem Materiekreislauf und E n t a l p i e die "freiwerdenede Energie" z.B bei chemischen E l e kt r o n e n r e a k t i o n e n zu neuen O r b i t a l e n , nachdem diese neue Elektronenverbindungen eingehen und Elektronenverteilungen über der Materie als Elektronenorbitale gebunden. In Kernen reagieren Teilchen unter betimmten Quanteneigenschaften. Neutronen selber stoßen sich unter Kinetik ab. In größeren rückfedernden Mengen reiben sie gegeneinander und ziehen sich auch rückoszillierend teils an, zunächst ganz ohne Elektronen "Q u a r k s" gibt es hier "g a r n i c h t " real.

Genauso machen es Elektronen. Nur bringen diese eine andere Grundquantenenergien als Ladung mit sich und zudem als viel kleinere Elementarteilchen. Nur kommen Protonen und Neutronen auch ohne Elektronen in einem b e s t i m m t e n M a g n e t f e l d nach Eichskala und unter bestimmter von außen angeregter Kinetik genausogut aus. Interessant wäre eine Magnetfeldgleichung, und Eichskala ab wann solche Gebilde wie scheinbare Ladungsquarks überhaupt erst so entstehen. Normal kommen sie ja gar nicht so vor. Hat man schon einmal unterchiedlich rotierende Neutronen zwischen zwei flachen Scheiben beobachtet Es könnten ja ansonst ohne e x p e r i m e n t e l l genauer auflösende Überprüfung j e n a c h M a g n e t f e l d s t ä r k e, E i n z e l - Neutronen können t h e o re t i s c h genauso gut aus 99% Up -Quark und nur 1 % Down - Quark G y r a t i o n s s p i n. entstehen.

Gibt es R e i b u n g s k o e f f i z i e n t e n für Neutronen ?

Angenommen man hat zwei Scheiben so groß wie ein Fußballplatz (vieleicht auch nur zwei runde Tischscheiben) und läßt hier mechanische Gegengyrationen von Neutronen in einer Ebene stattfinden, und stellt dann einmal eine Konstante hierzu auf bei g e n a u e r e n 3D Feldstärkedetektoren, mit hoher Auflösung und Ladungsmessungen, welche ins elektronenmikroskopische gehen, statt alles ohne experimentelle Modifikation (i s o e n t r o p i s c h) durchs Rohr zu heizen.

The story of the planetary boundaries is really old. They wrote their first paper about it in 2009, and keep it updating. This is the one of 2015: .Steffen, W., Richardson, K. & Rockstrom, J. Planetary boundaries: Guiding human development on a changing planet. Science 347, (2015).
Your ad segues are the best haha. For the lunar time - I decided to prompt GPT myself and just see the suggestions. Establishing a time system on the Moon presents unique challenges due to a variety of factors, including the lack of a natural lunar day-night cycle that aligns with Earth's 24-hour day, and the effects of time dilation due to the relative speeds and gravitational fields of the Earth, the Moon, and GPS satellites. Time Zones: Given the Moon's slower rotation relative to Earth (approximately 27.3 Earth days for a full lunar day), dividing the Moon into traditional time zones analogous to those on Earth would result in very long days and nights, which is counterintuitive for humans accustomed to Earth's 24-hour cycle. Instead, it might be simpler to adopt a single, uniform "Lunar Standard Time" (LST) based on a 24-hour clock. This would make timekeeping consistent across the Moon and easier to synchronize with Earth. Time Dilation: The effects of time dilation due to general and special relativity on GPS satellites are minute, but not negligible. These effects are well understood and can be accounted for in calculations. In a lunar context, time dilation effects would be even smaller due to the Moon's lower speed and weaker gravitational field compared to Earth. Thus, GPS-like systems designed for lunar use would have to be calibrated to account for these effects, just as Earth's GPS system is. Synchronization with Earth: To keep Lunar time coordinated with Earth, the LST could be set to sync with a specific point on Earth, such as the Coordinated Universal Time (UTC). This would make it easy for people on Earth and the Moon to coordinate activities. The exact synchronization procedure would depend on the relative positions of the Earth and Moon, and could be automated using signals from a lunar GPS-like system and Earth's GPS system. In fact, NASA's Lunar Reconnaissance Orbiter (LRO) already uses a similar approach to keep its onboard clock synchronized with Earth. Lunar Day-Night Cycle: As for the long lunar day-night cycle, this could be accounted for in local schedules, much as people in polar regions on Earth adjust their activities to the long days and nights. For instance, work and sleep cycles could be based on the 24-hour LST rather than local daylight. Artificial lighting could be used during the long lunar night. Calendar: A lunar calendar could be established based on the Moon's rotation and orbit around Earth. Each lunar day (from sunrise to sunrise) would be a "month", divided into 24 "hours". There would be approximately 13 "months" in a lunar "year". This calendar could be used for scheduling local activities, while the LST would keep time on a day-to-day basis.
Each time I listen to Sabine describe mission names I swear that universities must have “Creative Acronym Creation” as part of the science curriculums.
I found it funny that non-American scientists are so bad at creative acronyms. I suggested several acronyms to other groups and I am proud to learn that one German experiment with my acronym is actually still going on.
I'm not a physicist, but dark matter and dark energy always seemed like a massive fudge factor to me. And I know my fudge factors because I'm a statistical consultant and clients ask for them all the time.
If you look up "fudge factor" in Wikipedia they are in fact prime examples. But especially with dark matter (or MOND, if as Sabine does you distinguish them) there are multiple independent observations pointing to the need for a common explanation.
I am a physicist. They are, in fact, fudge factors. The problem comes from the names. Since the "we need more gravity" fudge factor behaves like extra mass, it got named "dark matter" (dark energy cam years later). But, my naming it Dark Matter, people seem to think there must actually be some sort of invisible matter causing all the trouble.
@@RocketsongYeah, the naming is unfortunate. We absolutely need a label to discuss the phenomenon of our universe behaving in ways not accountable to visible matter alone. But calling it dark matter kind of presupposes an answer we just don't have.
8:10. You left out one major issue with transmitting massively powerful microwaves from space. What happens if that beam is diverted, either accidentally or deliberately?
I've never heard of GMT (Greenwich Mean Time) being called Coordinated Universal Time (CUT), but I have heard it referred to as Universal Time Coordinates (UTC) - especially in transportation/aviation where you are often crossing time zones and need a standard frame of reference.
@@erchglas2528 Thanks for the link. I wasn't aware of the history of the abbreviation and how it arises as an unfortunate compromise between CUT and TUC (UTC being settled on because it satisfied no one)! I used to work in aviation IT in the UK and I'm pretty sure everyone in flight operations, etc., used 'Universal Time Coordinates' as the expansion of UTC (even if mistakenly).
It's Zulu time to me. "Zulu" is Navy talk for "Z", for "zero" meridian. Organizations which coordinate across time zones (e.g., brokerage houses, military command structures) use Zulu time.
@@Harriet1822 Sure, 'Zulu' time is a term used in commercial aviation as well, although possibly less than in the military because of the strong military associations (military vernacular/jargon can sound a bit odd in non-military settings). My remark related more to how the abbreviation UTC was typically expanded in the circles I moved in (albeit wrongly according to official ITU/IAU designation).
I have a few computer programs that call it UTC on the outside but everywhere on the inside it's GMT. I had to learn both since I first learned the concept in the military and we called it Zulu.
Active noise cancellation is easy. You just need a time machine, a mic, record, send that signal (with inverted polarity) slightly to the past so it exactly matches the timing of the background noise.
Hey Sabine: 👋🏻 *Do you think you might be able to maybe cover a story related to PFA's? I just saw a doc covering these forever chemicals & it really seems like it's worth hearing a scientist covering this. However you'd want to focus on it? Biology/ecological effects, Possible ways to improve the situation? It just seems like a new topic that could deserve more focus.. I could be wrong?
Time Zones - where everybody looses. I live in Arizona. We don't do daylight savings time. Seems like our life would be much simpler right? Our clocks never jump forward or spring back. We have so much year round daylight, we don't need to save any of it. But just because our life seems simple, it gets complicated for us and everyone else who isn't in Arizona when we communicate with each other. Meetings scheduled at 10am here with people say in California or New York, twice a year get moved. Suddenly a meeting at 10am with NY and a different one at 11am just among Phoenicians is at the same time, all because NY just switched to/from daylight savings time. In Arizona we have to remember, "Are we the same time as Calif or an hour off?" So no matter how you do 'moon' time and 'Terran' time, coordinating them together so people meet up at the same 'actual' time will always be a pain.
I've supported the notion that our understanding of gravity is imperfect ever since I studied astronomy and wrote a paper: "What's the matter?" as a Sophomore back in the '90s, when I first heard about dark matter. The notion that giving what you don't have a clue about an occult-sounding name struck me as at best, evading saying "I don't know," and at worst a flat-out hustle. I postulated that gravitational lensing produced the same effect on gravity that an ordinary lens has on light. Sophomoric, I know. Yet I still find it curious that along with dark matter, we have dark energy - each having the opposite effect on matter/space - if gravity is supposed to be the bending effect matter has on space. I'm with the MOND folks! In the remote chance that it hasn't crossed someone's mind, that actually knows what they're doing, I'd say look for equasions that describe warping below some limit, then begin to show expansion above that limit. It would look like a parabola facing the diretion of time, from negative to positive. Please forgive me if I've been presumptuous. I know I couldn't do something like that and I just wanted to hand it off to someone that can, if my observation is anywhere approaching the direction of correct. Thank you for your attention. Best regards, A fan.
Yes, we don't know, but the point is, "something with mass that doesn't interact with light" is one hypothesis. If dark matter is a "hustle", then so is MOND, if we're being consistent.
@@MijinLaw A further thought: maybe not so much a hustle as attention directed to the shadows on the cave wall, to use the ancient metaphor, rather than on what's casting the shadow. Could it be that all those diligently working on it are too close to the problem. Is gravity a property of space - as it appears with Einstein - rather than a property of matter? If QM is right, it would explain why we don't see a graviton, while gravitational waves could be space itself clanging like a bell. Could space itself be prone to random deformations that deflect light, giving the illusion of invisible matter? Or is space itself a field?
Hi Sabine! Thanks for wonderful science 🧬 news. Could you please also add the references for the topic’s you have chosen to include. It’ll be great help. I would like to dig deeper in some of them. As always I look forward for your amazing content and I like your sense of humor as well. I make some molecules for my living and astrophysics and astronomy 🪐 is my passion. Many thanks Sabine!! Clear skies 🌌!!
This is my biggest issue with this channel, not posting the source links. You literally have to type the paper title & authors into your favorite search engine (I avoid Google, I use Ecosia, instead, and have for several years), and hope you can find free access to the paper(s) somewhere. It's certainly not the best method, not like having a link. But it's something, I guess.
I would suggest a lunar mean time (lmt) to be a lunar longitude running through the point at the center of the full moon. It’s always* facing the earth. *it’s rotating.
Dark Matter is probably the biggest example of wishful thinking in Science, really. "Maybe it's this? Maybe it's that? Maybe it doesn't interact with itself? Perhaps it creates big planets? Perhaps it's an entirely new particle that requires energies higher than in a Magnetar?" It really always feels like whatever kind of fantasy took their fancy that week and every time they go "we didn't find evidence of this or that, that we predicted" they still scoff at any alternative, equally unproven ideas, about both large and small scale gravity. We already know that General Relativity is incomplete. We don't have a quantum theory of gravity and we can't explain a lot of things in the universe without invoking several competing theories... but Dark Matter is, to some, the only sensible answer.
Thank you for your hard work! This channel has absolutely skyrocketed to my favourite channel to watch on TH-cam. I love the compassionate, funny, and unbiased way to stay informed about science. Since I've become an adult, it's been so hard to keep my childhood love and interest in science, and you've made it so easy!
I have long been of the opinion that there is something deep and fundamental that we have missed. Dark matter, dark energy, modified gravity, they all smell of epicycles.
I wonder if that noise cancellation idea can be modified to make a soundproof room? Or at least a room that doesn't allow sound to escape. I'm imagining a use case in which loud equipment is housed in such a room allowing it to be used in a residential area without noise pollution.
Sabine, could you please talk about the ongoing Disclosure Project and the interesting physics novelties like Zero-point energy and technologies on propulsion and metamaterials? After some research i think there is really something going on...
@@ColtraneTaylor But if she does the work and come to that conclusion, that's fine! It's exactly what we need. especialy after Dr Greer's Press Conference with so many witness and highly reliable people telling their experience when in the US military service.
@@joaobarros6744 She and Penrose are not capable of that kind of work. A materialist creates and observes only within the limits of their understanding.
I've mentioned order from chaos, as with Benard cells. It turns out that convection begins via an oscillatory mode, not a stationary mode, because viscous relaxation, thermal diffusions, and internal heat generation mechanisms compete with one another. Below a certain critical value, there is no fluid motion and heat transfer is by conduction rather than convection. For most engineering purposes, the Rayleigh Number is large, somewhere around 10^6 to 10^8. To get technical, the Rayleigh Number is the product of the Grashof Number and the Prandtl number, and closely related to the Nusselt Number. But we don't need to worry about that, unless we're studying fluid mechanics. The Rayleigh number represents the ratio of buoyancy forces to viscous forces in a fluid. The onset and intensity of convection can be manipulated by adjusting the system’s controlling parameters, such as temperature gradients, fluid properties, and geometrical factors. So there are real-world applications for deferring or accelerating convective motions, for fine-tuning.
Thank you Dr. Hossenfelder for all the news, and your fascinating Science-telling. I always thought that Dark Matter is somewhat fishy, and the function is equal to the Ricci scalar; the simplest, the better...
Interessantíssimo!!! Interessantíssimo!!! Interessantíssimo!!! Gostei muito da notícia do cancelador de ruído que usa o mecanismo de interferência destrutiva e da notícia do desenvolvimento de moléculas orgânicas artificiais, não sabia que isso também é um tipo de simulação quântica e que tinha relação com simular a forma e o comportamento das nuvens de elétrons por meio de moléculas maiores.

These studies that observe different small systems organizing are fascinating to me. Always felt there’s something fundamental to how reality works in there, though have no idea what that may be 😂
oh boy, do I have the book for you en.wikipedia.org/wiki/A_New_Kind_of_Science (if that is a bit too much, here is a more intuitively accessible application of cellular automata th-cam.com/video/C2vgICfQawE/w-d-xo.html )
Haha. Love your injection of humour into the commentary. The motion of synchronized robots made me think about the turbulence inside a washing machine.
Thanks, Sabine! This dark-matter business is playing out EXACTLY like the Luminiferous Aether equivalent. (I 'got' the subtle reference to 'the big man'...)
Microwave Energy from Space: This was discussed in science fiction mag "Analog" around 190s to 1980s. One big problem is the microwave beam will heat the air around it and fry birds and airplanes that fly through it.
Dark matter has always seemed like a silly mcguffin. What's more likely: a new form of matter, or we don't understand mass distribution and rotational curves in galaxiea?
The problem with other models is that they cannot account for other processes that dark matter does predict, like the peaks in the microwave background or the bullet cluster. Dark matter can account for both plus the rotation of galaxies. MOND can explain the rotation of galaxies, and maybe the CMB but not the bullet cluster. It seems very very hard for me to believe that a bullet cluster cannot be caused by something that barely interacts with baryonic matter
I wonder what you would say before discovery of electricity. If we don't understand something as simple as the dependency of rotational curves on mass distribution, why would you assume we know everything there is to know about the fundamental building blocks of the universe?
Yet the evidence for the existence of dark matter is very strong. I don't see how MOND theory will explain how it only applies to some galaxies and not others - some galaxies have very little dark matter while others have more than average.
You always ask good questions Sabine. I coined the phrase dark energy and got taken to task for it by Penrose who said well we liked the Cosmological constant. Surely there is a better way to describe it than dark energy. Sorry. I know it wasn't crazy enough. The ether absolute spacetime is made up of tiny bubbles that pulse in and out as they resist the big suck. (Taking the wind out of the big bang) They define space. So if the universe expands they have no space to expand into so they remain the same size but the effect is that they are expanding or being forced to pulse in and out depending on the pressure in the gravity well. So that shows up as background radiation. Does it have mass? Well it is a bubble with tensile strength touching other bubbles. Pick one up close to the sun and pick one up close to the earth they are not the same size, but they are both Planck length in diameter. Crazy enough right there because the pressure of the gravity well is shrinking them but if they were to do their function they do it as an object that is Planck length since all our measurements measure interactions that are uniform regardless of the depth of the gravity well. Lift an atomic clock it will obey Einstein. So the ether is both energy (kinetic energy) and mass. e=mc2 Intrinsic mass inertia because they pulse in and out in a straight line. And we go crazier and say f=ma is the same formula as w=mg. Now look inside a black hole, are those quantum bubbles that transmit light by passing on momentum, are they being stifled? Are the nucleus bubbles being stifled? they pulse in and out on their natural frequency like an atomic clock. Is the matter moving back in time? If expansion is forward t or times arrow, then that must be negative t. Edit: Was Sabine merely saying I know what you did last summer to me in her offensive reply. If you investigate who I am you will not be able to make me a public figure. I had to move people from off planet to the earth and they were terrified by movies depicting Wrath of Khan and One Flew Over the Cuckoos nest so I had to infiltrate the psychiatry put myself in, act crazy and show them they do not hand out frontal lobotomies if you make outrageous claims. So the first time the psychiatrist said are you finished looking over our shoulder in innuendo. I said yes now that you have said that I am satisfied. But I still had to go further and do it two more times on different subject matter. I had to go and say they put a little creature in my body. For Wrath of khan. And then got released right away. So on what happens if you commit suicide and fail so I faked taking some pills they arrived now starting to get annoyed at me for making them jump through hoops. So they sent me a letter and said here, now you are officially crazy. And so then that right away gives me a legal excuse for anything on earth. lol And of course I have never had to use it. But the fact remains that I got everyone to earth and true I will never be mayor as a result but a man has to do what a man has to do, and I am no worse for wear as a result and accomplished my mission. So my reference to crazy above was from a quote from Bohr that everyone should know. "The question is not is quantum theory too crazy a theory, the question is, is it crazy enough" But I can't communicate with people who do not know how to communicate in a non confrontational manner, I am sorry but I didn't want to leave Sabine with a guilty conscience so I added this for her.
@058 That's what I mean Sabine. Everyone wants to speak to a higher civilization, but they are animals, and not pets and only Dr. Do little would want to talk to them.
@058 Ok so I am from a higher civilization with proof but if you try to speak to people they say you are crazy. Sabine is a physicist she just called me a schizo. Meanwhile any technology I have would be seen as magic even Arthur C. Clark knew that. So the problem is communications. Humans appear intelligent but from my perspective they are a f*cking disaster and a world full of miscreations. They have broken laws of colonization that would condemn any race for eternity. The stargate door at Coricancha was breach by natives breaching the quarantine and as a result over 50 planets were destroyed. Now you can call me crazy because you didn't have to go and clean up that wreckage like I did, rescue the files reincarnate the people onto the earth. You can call me crazy, but I hold your souls in my machine. Now you can call me crazy, but that isn't helping your case at all. ibb.co/KFhcKYP Read em and weep Sabine.
Sabine, You are very funny! Thank you for helping me enjoy the journey attempting to answer the question, “ what is really going on?” Your talk today with the president was so funny!
Every time I hear about this I can't help but think that it has huge potential to go wrong. Instead of fixing a problem they cause new ones by tinkering with the wrong systems on accident (or on purpose). Maybe I'm thinking about this wrong but I don't want my life dependant on whether my nanobots have the latest security patch so I can't be hacked by some terrorist.
Sabine - you are amazing. Thank you for elucidating all of the things I have struggled to get my mind around. You are wonderfully and the best science communicator I've ever seen. Thank you. Your work is doing wonders ❤
in case you hadn't noticed physics seems to be unable to progress to a new level of understanding and your idol is saying she is as baffled as everyone
Phonon breathing mode is reminiscent of scalar curvature of GR 🌍 4:35 This is how breathing and other modes are described by theosophists: "The Anu has--as observed so far--three proper motions, i.e., motions of its own, independent of any imposed upon it from outside. It turns incessantly upon its own axis. spinning like a top; it describes a small circle with its axis, as though the axis of the spinning top moved in a small circle; it has a regular pulsation, a contraction and expansion, like the pulsation of the heart."
It's interesting just how important the Photoelectric effect and Electromagnetism is throughout every aspect of our Cosmo's. Mass, energy, temperature, density, charge state, wavelength frequency, etc. (I wonder if we are running into issues due to the way light can seem to be manipulated.. like how light bends when passing through water, or how the wavelength changes due to distance, etc. It's probably pretty difficult to get truly accurate readings throughout our Cosmo's..
Um, what? Nearly all of what you listed won't change or bend when going through the universe. Gamma rays through to x-rays do change strength and drop the next level down, but the rest don't.
Multiple time/date systems for the moon have been experimented with already. One is known as LST (Lunar Standard Time) July 20th is the Lunar New Year, so the current year is 53.
As a general rule, scientists (maybe just physicists?) should avoid trying to be funny, but every now and then Sabine’s deadpan delivery catches me with a laugh.
This might be another one of the those white/blue dress illusions, but while Sabine says the 'Safe' lines on the chart of ecosystem boundaries are purple, I see brown. On my monitor anyway the lines appear to have an RGB of around 84, 25, 18 which does seem to be in the 'brown' range.
They are brown, but may appear purple on cool-tinted monitors. The one in proximity to blue in particular looks purple at a small scale, especially with a dim screen
16:05 Actually, I think there is a technical difference between the definitions of GMT and UTC. Basically, the official definition of GMT is actually ambiguous as to whether it agrees with UTC or UT1.
13:57 those waves can serve propagation of communication signals, just like synapses in the nervous system or the ERK wave signalling used for collective cell migration behaviour, e.g. wound-healing, cancer.

the “theories” are things like axioms, WIMPs…
@@Somebodyherefornow that is not quite true. First we never observed Dark Matter. It only seems the best explanation for what we observe. And second, everything that we observe which seems to follow some rules and laws, ideally being scientific should and can be described by a theory, which over time might get refined or even replaced by a more comprising theory. Would you agree on that?
The first story seems to be about my favorite trend in science: Making your results by altering your datasets. Makes understanding results very frustrating because you can't trust them without understanding something about data or method.
hmm?
I think that was the 5th story.
I don't think the point was about cherry-picking, more that the data might have by chance not been appropriate for demonstrating / refuting MOND.
Also, I think Sabine is on the side of preferring MOND...I'm not saying she's not objective, but this isn't the channel where you're going to hear "MOND has been basically ruled out".
Right. They are now basically competing over who has bigger bs sigma 🤣

Cool to see the paper on Artificial Atoms with Scanning Tunneling Microscopy (STM) featured on this channel, which is my field of research! When Alex Khajetoorians presented these results at a conference a few months ago, we were all very impressed (or at least the few people in the room that do STM, which is how it always is). Many attempts have been made over the last 15 years to develop a platform for artificial molecules that is both versatile and scalable, and these Cesium atoms on Idium-tin seem really promising.
The tool in the field is the STM, which is in essence a needle with an atomically sharp tip. Therefore, if you scan over an atom (on a flat surface) you have the spatial resolution to observe it. But an STM is more than just a microscope. It is also a tool for 'atom engineering': you can pick up an atom and drop them off at another place on the surface, all with atomic precision! This is why STM is such a great technique for molecule simulation. However, if you cannot practically scale up your atomic structure, you stay in the regime of trivial artificial molecules. I hope that the group in Nijmegen (Radboud University) is able to deliver on the potential.
In the meantime, I'll stay working on my nice collection of magnetic atoms.
I was transfixed when I saw the electron getting agitated before the quantum jump to an higher level; similarly to when it returned to its original energy state.
I always imagined the jump as an instantaneous transaction, not as a carefully choreographed interaction between photon and electron. Physics never cease to amaze me...
Hi Evert, thanks for adding this context!
It's amazing tech but seems like it could be miniaturised into arrays some day. Imagine a tiny dot matrix printer head with electric pins (grid of electrified pins that can move up and down and change voltage). This could pick up multiple atoms and deposit them in a pattern. Maybe that phonon chip tech mentioned earlier could help. I could imagine this tech getting 1000s of times faster within 50 years. Could be useful to make chip die prototypes cheaply and rapidly at some point, even advanced, picometer chip fabs.
Not going to lie, i absolutely love what you’re doing Sabine. I’ve been looking for non-biased science news forever. Please never stop!!!
'Non-biased' is a bit much.. Less biased than many scientists and science journalists but still pretty biased. A good example of this vid was not questioning the Far Liberal Lefty propaganda surrounding the stupidly simplified climate change rating system and the throw away comment that translates as 'as if humans are going to simply follow advice', implying they need to be FORCED (by Fake-Green global and national institutions).. Funny, because when this was done manufacturing was rapidly moved from The West to The Rest who then rapidly tripled their populations from around 2 billion to around 6 billion in just 50 years while increasing pollution to many times pre 1980s levels... Uber-Green Regulation in The West acted as an excuse to hyper-pollute The Rest.
Is this something you'd ordinarily lie about?

As someone who works in videogames, the micro robot "research" that you talked about just looks like the first draft of the AI I make before I work out the bugs
And i hope you know the bugs.
Use Newtons equations.
Good to hear there are at least some people in the video game industry that are interested in working out bugs instead of leaving it up to the player base. But yeah, when I looked at what those scientists were doing it seemed utterly elementary for anyone used to fooling around with graphics. Well, scientists need to publish papers and evidently one of the easiest ways to do that is take something simple, obfuscate it with big words, and paste it into a boilerplate scientific paper form.
@@marcelmolenaar5684 Virtual bugs don't need no Newton equations... Which, maybe ironically, is going to turn out to be one of the problems with AI. Or, maybe it will like what the cold virus did to the aliens from Mars in HG Wells War of the worlds?
This is a case where you actually want more bugs, not less!
The point of the research was to stick to limitations present in manufacturing microscopic bots. The way life makes things work is it exploits emergent behavior of the organic molecules wiggling about, and better understanding emergent properties of collections of simple machines could help with developing nanobots.

Your ad segues are the best haha.
For the lunar time - I decided to prompt GPT myself and just see the suggestions.
Establishing a time system on the Moon presents unique challenges due to a variety of factors, including the lack of a natural lunar day-night cycle that aligns with Earth's 24-hour day, and the effects of time dilation due to the relative speeds and gravitational fields of the Earth, the Moon, and GPS satellites.
Time Zones: Given the Moon's slower rotation relative to Earth (approximately 27.3 Earth days for a full lunar day), dividing the Moon into traditional time zones analogous to those on Earth would result in very long days and nights, which is counterintuitive for humans accustomed to Earth's 24-hour cycle. Instead, it might be simpler to adopt a single, uniform "Lunar Standard Time" (LST) based on a 24-hour clock. This would make timekeeping consistent across the Moon and easier to synchronize with Earth.
Time Dilation: The effects of time dilation due to general and special relativity on GPS satellites are minute, but not negligible. These effects are well understood and can be accounted for in calculations. In a lunar context, time dilation effects would be even smaller due to the Moon's lower speed and weaker gravitational field compared to Earth. Thus, GPS-like systems designed for lunar use would have to be calibrated to account for these effects, just as Earth's GPS system is.
Synchronization with Earth: To keep Lunar time coordinated with Earth, the LST could be set to sync with a specific point on Earth, such as the Coordinated Universal Time (UTC). This would make it easy for people on Earth and the Moon to coordinate activities. The exact synchronization procedure would depend on the relative positions of the Earth and Moon, and could be automated using signals from a lunar GPS-like system and Earth's GPS system. In fact, NASA's Lunar Reconnaissance Orbiter (LRO) already uses a similar approach to keep its onboard clock synchronized with Earth.
Lunar Day-Night Cycle: As for the long lunar day-night cycle, this could be accounted for in local schedules, much as people in polar regions on Earth adjust their activities to the long days and nights. For instance, work and sleep cycles could be based on the 24-hour LST rather than local daylight. Artificial lighting could be used during the long lunar night.
Calendar: A lunar calendar could be established based on the Moon's rotation and orbit around Earth. Each lunar day (from sunrise to sunrise) would be a "month", divided into 24 "hours". There would be approximately 13 "months" in a lunar "year". This calendar could be used for scheduling local activities, while the LST would keep time on a day-to-day basis.
Each time I listen to Sabine describe mission names I swear that universities must have “Creative Acronym Creation” as part of the science curriculums.
I found it funny that non-American scientists are so bad at creative acronyms. I suggested several acronyms to other groups and I am proud to learn that one German experiment with my acronym is actually still going on.
It’s the same people that name micro brew beers and cannabis strains.
They should call it CrAcC
Good thing you aren't in charge of the CAC curriculum because you've already failed. 😂
It's what they're best at.
I'm not a physicist, but dark matter and dark energy always seemed like a massive fudge factor to me. And I know my fudge factors because I'm a statistical consultant and clients ask for them all the time.
If you look up "fudge factor" in Wikipedia they are in fact prime examples.
But especially with dark matter (or MOND, if as Sabine does you distinguish them) there are multiple independent observations pointing to the need for a common explanation.
I am a physicist. They are, in fact, fudge factors. The problem comes from the names. Since the "we need more gravity" fudge factor behaves like extra mass, it got named "dark matter" (dark energy cam years later). But, my naming it Dark Matter, people seem to think there must actually be some sort of invisible matter causing all the trouble.
@@michaelmicek I am wondering whether MOND includes ideas like electrical universe. Because that one seems to make a lot of sense.
@@RocketsongYeah, the naming is unfortunate. We absolutely need a label to discuss the phenomenon of our universe behaving in ways not accountable to visible matter alone. But calling it dark matter kind of presupposes an answer we just don't have.

I've never heard of GMT (Greenwich Mean Time) being called Coordinated Universal Time (CUT), but I have heard it referred to as Universal Time Coordinates (UTC) - especially in transportation/aviation where you are often crossing time zones and need a standard frame of reference.
Nope, UTC does stand for Coordinated Universal Time, "obviously". See e.g. en.wikipedia.org/wiki/Coordinated_Universal_Time
@@erchglas2528 Thanks for the link. I wasn't aware of the history of the abbreviation and how it arises as an unfortunate compromise between CUT and TUC (UTC being settled on because it satisfied no one)! I used to work in aviation IT in the UK and I'm pretty sure everyone in flight operations, etc., used 'Universal Time Coordinates' as the expansion of UTC (even if mistakenly).
It's Zulu time to me. "Zulu" is Navy talk for "Z", for "zero" meridian. Organizations which coordinate across time zones (e.g., brokerage houses, military command structures) use Zulu time.
@@Harriet1822 Sure, 'Zulu' time is a term used in commercial aviation as well, although possibly less than in the military because of the strong military associations (military vernacular/jargon can sound a bit odd in non-military settings). My remark related more to how the abbreviation UTC was typically expanded in the circles I moved in (albeit wrongly according to official ITU/IAU designation).
I have a few computer programs that call it UTC on the outside but everywhere on the inside it's GMT. I had to learn both since I first learned the concept in the military and we called it Zulu.
We should not “agree on which day to switch to summer time”. We should agree to abolish it entirely.
Active noise cancellation is easy. You just need a time machine, a mic, record, send that signal (with inverted polarity) slightly to the past so it exactly matches the timing of the background noise.

Hey Sabine: 👋🏻
*Do you think you might be able to maybe cover a story related to PFA's? I just saw a doc covering these forever chemicals & it really seems like it's worth hearing a scientist covering this. However you'd want to focus on it? Biology/ecological effects, Possible ways to improve the situation? It just seems like a new topic that could deserve more focus.. I could be wrong?
Every few hundred years, the simulators have had to issue an update to us. Dark Matter is just a bug waiting for a patch 😅
Time Zones - where everybody looses. I live in Arizona. We don't do daylight savings time. Seems like our life would be much simpler right? Our clocks never jump forward or spring back. We have so much year round daylight, we don't need to save any of it. But just because our life seems simple, it gets complicated for us and everyone else who isn't in Arizona when we communicate with each other. Meetings scheduled at 10am here with people say in California or New York, twice a year get moved. Suddenly a meeting at 10am with NY and a different one at 11am just among Phoenicians is at the same time, all because NY just switched to/from daylight savings time. In Arizona we have to remember, "Are we the same time as Calif or an hour off?" So no matter how you do 'moon' time and 'Terran' time, coordinating them together so people meet up at the same 'actual' time will always be a pain.
I've supported the notion that our understanding of gravity is imperfect ever since I studied astronomy and wrote a paper: "What's the matter?" as a Sophomore back in the '90s, when I first heard about dark matter. The notion that giving what you don't have a clue about an occult-sounding name struck me as at best, evading saying "I don't know," and at worst a flat-out hustle.
I postulated that gravitational lensing produced the same effect on gravity that an ordinary lens has on light. Sophomoric, I know. Yet I still find it curious that along with dark matter, we have dark energy - each having the opposite effect on matter/space - if gravity is supposed to be the bending effect matter has on space.
I'm with the MOND folks! In the remote chance that it hasn't crossed someone's mind, that actually knows what they're doing, I'd say look for equasions that describe warping below some limit, then begin to show expansion above that limit. It would look like a parabola facing the diretion of time, from negative to positive.
Please forgive me if I've been presumptuous. I know I couldn't do something like that and I just wanted to hand it off to someone that can, if my observation is anywhere approaching the direction of correct.
Thank you for your attention.
Best regards,
A fan.
Yes, we don't know, but the point is, "something with mass that doesn't interact with light" is one hypothesis. If dark matter is a "hustle", then so is MOND, if we're being consistent.
@@MijinLaw BTW: Thank you for your response, Mr Holtom.
@@MijinLaw A further thought: maybe not so much a hustle as attention directed to the shadows on the cave wall, to use the ancient metaphor, rather than on what's casting the shadow. Could it be that all those diligently working on it are too close to the problem. Is gravity a property of space - as it appears with Einstein - rather than a property of matter? If QM is right, it would explain why we don't see a graviton, while gravitational waves could be space itself clanging like a bell. Could space itself be prone to random deformations that deflect light, giving the illusion of invisible matter? Or is space itself a field?

Dark Matter is like Schrödinger's cat, it's everywhere and nowhere at the same time. 😄
Your not helping my paranoia
Dark Matter is probably the biggest example of wishful thinking in Science, really. "Maybe it's this? Maybe it's that? Maybe it doesn't interact with itself? Perhaps it creates big planets? Perhaps it's an entirely new particle that requires energies higher than in a Magnetar?"
It really always feels like whatever kind of fantasy took their fancy that week and every time they go "we didn't find evidence of this or that, that we predicted" they still scoff at any alternative, equally unproven ideas, about both large and small scale gravity.
We already know that General Relativity is incomplete. We don't have a quantum theory of gravity and we can't explain a lot of things in the universe without invoking several competing theories... but Dark Matter is, to some, the only sensible answer.
Thank you for your hard work! This channel has absolutely skyrocketed to my favourite channel to watch on TH-cam. I love the compassionate, funny, and unbiased way to stay informed about science. Since I've become an adult, it's been so hard to keep my childhood love and interest in science, and you've made it so easy!
Laughed when you said the tungsten atoms found it breathtaking 😅
I have long been of the opinion that there is something deep and fundamental that we have missed.
Dark matter, dark energy, modified gravity, they all smell of epicycles.
I wonder if that noise cancellation idea can be modified to make a soundproof room? Or at least a room that doesn't allow sound to escape. I'm imagining a use case in which loud equipment is housed in such a room allowing it to be used in a residential area without noise pollution.

I've mentioned order from chaos, as with Benard cells. It turns out that convection begins via an oscillatory mode, not a stationary mode, because viscous relaxation, thermal diffusions, and internal heat generation mechanisms compete with one another.
Below a certain critical value, there is no fluid motion and heat transfer is by conduction rather than convection. For most engineering purposes, the Rayleigh Number is large, somewhere around 10^6 to 10^8.
To get technical, the Rayleigh Number is the product of the Grashof Number and the Prandtl number, and closely related to the Nusselt Number. But we don't need to worry about that, unless we're studying fluid mechanics. The Rayleigh number represents the ratio of buoyancy forces to viscous forces in a fluid. The onset and intensity of convection can be manipulated by adjusting the system’s controlling parameters, such as temperature gradients, fluid properties, and geometrical factors. So there are real-world applications for deferring or accelerating convective motions, for fine-tuning.
Thank you Dr. Hossenfelder for all the news, and your fascinating Science-telling.

Every time I hear about MOND I wonder how it explains the Dark Matter leaving the Bullet Cluster. Gotta see if there are any videos on that.
Sabine is the only person that keeps me sane. Thanks sabine 😂😂
Microwave Energy from Space: This was discussed in science fiction mag "Analog" around 190s to 1980s. One big problem is the microwave beam will heat the air around it and fry birds and airplanes that fly through it.
Dark matter has always seemed like a silly mcguffin. What's more likely: a new form of matter, or we don't understand mass distribution and rotational curves in galaxiea?
The problem with other models is that they cannot account for other processes that dark matter does predict, like the peaks in the microwave background or the bullet cluster. Dark matter can account for both plus the rotation of galaxies. MOND can explain the rotation of galaxies, and maybe the CMB but not the bullet cluster. It seems very very hard for me to believe that a bullet cluster cannot be caused by something that barely interacts with baryonic matter
I wonder what you would say before discovery of electricity.
If we don't understand something as simple as the dependency of rotational curves on mass distribution, why would you assume we know everything there is to know about the fundamental building blocks of the universe?
Yet the evidence for the existence of dark matter is very strong.
I don't see how MOND theory will explain how it only applies to some galaxies and not others - some galaxies have very little dark matter while others have more than average.
A new form of matter.
You're right DM is antiscience
Thank you kind SponsorBlock user for filtering out the filler/noise phone segment.
This video is why Sabine is so good! There really is no other channel like it in the world
You always ask good questions Sabine.
I coined the phrase dark energy and got taken to task for it by Penrose who said well we liked the Cosmological constant. Surely there is a better way to describe it than dark energy.
Sorry. I know it wasn't crazy enough.
The ether absolute spacetime is made up of tiny bubbles that pulse in and out as they resist the big suck.
(Taking the wind out of the big bang) They define space. So if the universe expands they have no space to expand into so they remain the same size but the effect is that they are expanding or being forced to pulse in and out depending on the pressure in the gravity well.
So that shows up as background radiation. Does it have mass? Well it is a bubble with tensile strength touching other bubbles. Pick one up close to the sun and pick one up close to the earth they are not the same size, but they are both Planck length in diameter. Crazy enough right there because the pressure of the gravity well is shrinking them but if they were to do their function they do it as an object that is Planck length since all our measurements measure interactions that are uniform regardless of the depth of the gravity well.
Lift an atomic clock it will obey Einstein.
So the ether is both energy (kinetic energy) and mass. e=mc2 Intrinsic mass inertia because they pulse in and out in a straight line. And we go crazier and say f=ma is the same formula as w=mg.
Now look inside a black hole, are those quantum bubbles that transmit light by passing on momentum, are they being stifled? Are the nucleus bubbles being stifled? they pulse in and out on their natural frequency like an atomic clock. Is the matter moving back in time? If expansion is forward t or times arrow, then that must be negative t.
Edit: Was Sabine merely saying I know what you did last summer to me in her offensive reply.
If you investigate who I am you will not be able to make me a public figure.
I had to move people from off planet to the earth and they were terrified by movies depicting Wrath of Khan and One Flew Over the Cuckoos nest so I had to infiltrate the psychiatry put myself in, act crazy and show them they do not hand out frontal lobotomies if you make outrageous claims.
So the first time the psychiatrist said are you finished looking over our shoulder in innuendo. I said yes now that you have said that I am satisfied.
But I still had to go further and do it two more times on different subject matter.
I had to go and say they put a little creature in my body. For Wrath of khan.
And then got released right away.
So on what happens if you commit suicide and fail so I faked taking some pills they arrived now starting to get annoyed at me for making them jump through hoops.
So they sent me a letter and said here, now you are officially crazy.
And so then that right away gives me a legal excuse for anything on earth. lol
And of course I have never had to use it.
But the fact remains that I got everyone to earth and true I will never be mayor as a result but a man has to do what a man has to do, and I am no worse for wear as a result and accomplished my mission.
So my reference to crazy above was from a quote from Bohr that everyone should know.
"The question is not is quantum theory too crazy a theory, the question is, is it crazy enough"
But I can't communicate with people who do not know how to communicate in a non confrontational manner, I am sorry but I didn't want to leave Sabine with a guilty conscience so I added this for her.
@058 That's what I mean Sabine. Everyone wants to speak to a higher civilization, but they are animals, and not pets and only Dr. Do little would want to talk to them.
@058 Ok so I am from a higher civilization with proof but if you try to speak to people they say you are crazy. Sabine is a physicist she just called me a schizo. Meanwhile any technology I have would be seen as magic even Arthur C. Clark knew that. So the problem is communications. Humans appear intelligent but from my perspective they are a f*cking disaster and a world full of miscreations. They have broken laws of colonization that would condemn any race for eternity. The stargate door at Coricancha was breach by natives breaching the quarantine and as a result over 50 planets were destroyed.
Now you can call me crazy because you didn't have to go and clean up that wreckage like I did, rescue the files reincarnate the people onto the earth.
You can call me crazy, but I hold your souls in my machine.
Now you can call me crazy, but that isn't helping your case at all.

Read em and weep Sabine.
Thank you team! Please alsway use SI units, instead of feet
To me, dark matter is philosophy until proven otherwise.
Dark matter is a phenomenon.... Not even an idea lol
Either this is very poorly worded, or you understand neither philosophy nor proof.
Tell me you have no fuckn idea 💡
@@blackshard641 Nope, worded perfectly. I guess I'm just not as easily tricked as you are. Enjoy your shiny, bright object adoration while it lasts.
@@asafoster7954 ghosts are a phenomenon too. And yet we still have no proof of them either.
Sabine, the collector on Earth can be raised above crops and/or grazing land. The collector doesn't allow the beam to touch the ground.
‘We’re missing something important’. Give that girl a Nobel Prize!

Please do a video on Alexandre Deur's self-interacting gravity theories!
Cosmologists: which model is correct, dark matter or MOND?
the universe: yes
7:42 wasn't that literally the highest tier energy source in Sim City 2000?
Sabine, You are very funny! Thank you for helping me enjoy the journey attempting to answer the question, “ what is really going on?” Your talk today with the president was so funny!
I am very excited for nanobot swarms. So many medical applications yet to come.
Every time I hear about this I can't help but think that it has huge potential to go wrong. Instead of fixing a problem they cause new ones by tinkering with the wrong systems on accident (or on purpose). Maybe I'm thinking about this wrong but I don't want my life dependant on whether my nanobots have the latest security patch so I can't be hacked by some terrorist.
LOVED the call from Mr President!!🤣🤣
Hi Sabine just found your channel. You're so funny! Thanks for making Science interesting!
How do you scientifically calculate "just boundaries " ?!
sharp as a samourai sword as always, respect for your work sabine!
3:03 Sabine, shows a graphic for 5 seconds: „This is what you would expect if MOND was right“
Me: „Okey“
Pause buttons are wonderful things.
@@MaryAnnNytowla legend even more 😉
It's not the fuel that needs to be changed but the motors-engines to work with something more available and wide-spread such as salty-water.
Love the Safe and Just Boundaries. This is how science should be used and the world organized. Sadly, the short term greed boundary will always win.
Sabine - you are amazing. Thank you for elucidating all of the things I have struggled to get my mind around. You are wonderfully and the best science communicator I've ever seen. Thank you. Your work is doing wonders ❤
in case you hadn't noticed physics seems to be unable to progress to a new level of understanding and your idol is saying she is as baffled as everyone
5:52 Very good humor: "Noise reduction is a booming business" 😂😅😊
Phonon breathing mode is reminiscent of scalar curvature of GR 🌍 4:35
This is how breathing and other modes are described by theosophists: "The Anu has--as observed so far--three proper motions, i.e., motions of its own, independent of any imposed upon it from outside. It turns incessantly upon its own axis. spinning like a top; it describes a small circle with its axis, as though the axis of the spinning top moved in a small circle; it has a regular pulsation, a contraction and expansion, like the pulsation of the heart."
It's interesting just how important the Photoelectric effect and Electromagnetism is throughout every aspect of our Cosmo's. Mass, energy, temperature, density, charge state, wavelength frequency, etc. (I wonder if we are running into issues due to the way light can seem to be manipulated.. like how light bends when passing through water, or how the wavelength changes due to distance, etc. It's probably pretty difficult to get truly accurate readings throughout our Cosmo's..
Um, what? Nearly all of what you listed won't change or bend when going through the universe. Gamma rays through to x-rays do change strength and drop the next level down, but the rest don't.
Your news leads me in so many adventures. Thank you.
12:20 wtf is that stock image? The brown, green and yellow gear can't turn, they block each other.
What about the Janus model from JP Petit? That seems to explain all observation issues.
better and better -- thank you!
Hi it doesn't matter about the content, your presentation is just so good. Thanks for making science so much fun!
When my math teacher said the answers to her questions were way off. I said did you take into account dark matter ? :D
Love your channel! Just subscribed
12:43 Ouch! Take that Dr. Phil
Time being relative is so underrepresented in current society.
Multiple time/date systems for the moon have been experimented with already.
One is known as LST (Lunar Standard Time)
July 20th is the Lunar New Year, so the current year is 53.
What?
Breathtaking. Nice one.
13:53: swarm behaviour like starlings gathering.
As a general rule, scientists (maybe just physicists?) should avoid trying to be funny, but every now and then Sabine’s deadpan delivery catches me with a laugh.
This might be another one of the those white/blue dress illusions, but while Sabine says the 'Safe' lines on the chart of ecosystem boundaries are purple, I see brown. On my monitor anyway the lines appear to have an RGB of around 84, 25, 18 which does seem to be in the 'brown' range.
They are brown, but may appear purple on cool-tinted monitors. The one in proximity to blue in particular looks purple at a small scale, especially with a dim screen
The only time I need noise cancelation around these quiet parts is when the witch starts screaming and bellowing in the woods.
Sound control reminds me of language translators on Star trek. Each person hears the translation they understand.
As a software engineer, handling relativity and 'moon time' in databases sounds like a nightmare lol.
I speculated that elements in the number 400-460 might be the stable and non interactive (given completed E shells)
Great! "Atomic Lettuce" will be stuck in my head now!
I always figured the term "dark matter" was just a place holder meaning "we don't know but something's happening"
10:48 facial expression when the telephone rings 😂
16:05 Actually, I think there is a technical difference between the definitions of GMT and UTC. Basically, the official definition of GMT is actually ambiguous as to whether it agrees with UTC or UT1.
13:57 those waves can serve propagation of communication signals, just like synapses in the nervous system or the ERK wave signalling used for collective cell migration behaviour, e.g. wound-healing, cancer.
How about using it for long distance, rechargeable satellites instead?
Or Mars rovers, etc.
"the" timezone for Canada? Your humour is quite subtle at times 😊
5:53 - “Noise reduction is a booming business.” Science brought me here, the cheesy puns keep me coming back. ^.^
