14:00 If the Oort Cloud extends halfway to the next star system the outer objects must be equally influenced by both systems. The saying “ No man is an island” is applicable to every thing in the entire universe to some degree.
I said this like 10 years ago. Every solar system in the galaxy is connected via their own Oort clouds...So material from all systems crosses over to each other. That's how we get comets etc. Not forgetting that star systems constantly cross into each others systems. I wouldn't be surprised if there were planets that orbit multiple star systems from far out...
Thanks for all the astronomy goodness. Between this channel and universe today I know I won't miss anything important. I have to admit I cheat on you with Anton and Dr Becky from time to time.

Could distant binary blackhole pairs synchronize to each other via resonance, sorta like pendulum clocks on a shelf? Has the Universe existed long enough for that to happen?
Thanks for the news, Fraser! 😊 About the adpocalypse, don't worry. It's a fabricated crisis... And I don't think it's going to work this time. Anyway, stay safe there with your family! 🖖😊
I propose to call an object in the Oortcloud an 'oort'. And an object in the Kuyper belt a 'Kuyper'. Just to be consistent with the asteroid belt and the trojan clouds
I have a question for the QnA; ive read Artemis the book by Andy Weir and i was wondering is 2 six cm aluminium plates and a meter of crushed rock enough to protect people that would live on the moon, what about the 27cm thick glass? love your videos!
As usual, great video! Regards the gravity waves, I've two questions: * The energy of light waves increases with frequency. With gravitational waves it seems to be the other way around.??? * The black holes' gravitational waves are supposed to oscillate in phase, thereby creating these very low frequency waves. I cannot imagine how this could occur. If one thinks of a pond upon which raindrops fall, the ripples they cause cancel each other out and never get in synch. So, how???
Fraser, do you happen to know what frequency the background hum from The Milky Way is? I am an amateur radio operator and was wondering if it could be heard..
@@frasercain There are already constraints that rule out any particle explanation, the conflicting constraints on self interaction cross section from the bullet cluster vs the train wreck cluster.
❤ Hey Fraser! The firing of the engines to keep the second stage in motion serves a purpose I had not given thought to and was mentioned in passing, on one of the SpaceX, or other channel [sorry], .. and, that was the fuel orientation and weight, so as to keep fuel in the tank close to the engine, and not have several wasted seconds of realigning its masses in motion. I believe it was 12 seconds of effort, and could save 10% of fuel cost, or such.. Could you look into this?
I saw an article this week about how events in the early universe appear to happen in slow motion because of time dilation. I was wondering if this could be a reason behind the “crisis in cosmology”. Would supernova apparently happening slower than one would expect throw their measurements off? On the other hand if there’s a predictable periodicity to cosmic phenomena, can’t differences in the measured time vs “known” time be used as a different kind of cosmic ladder? Maybe they’re doing this already?
QUESTION: Is the way that the OrtCloud surrounds the solar system analogous to how electrons surround an atom? How can the source of comets be calculated to come from outside the solar system if the OrtCloud surrounds us?
I have a question! We see stellar nurseries like the Orion nebula and the Pillars of Creation. These nebulae are the birthplaces of hundreds of star-siblings. My question is do we know what the Sun's siblings are? Is it as simple as the Centauris, Sirius, Procyon, and the dozens of nearby red dwarfs or could our stellar siblings have drifted over the 4.5+ b years since the Sun's (and its siblings') formation?
If we can see the residual light from the beginning of light as the CMB then it is possible we could be seeing the residual gravity waves from the first supermassive black hole mergers. Since gravity isn't electromagnetic radiation, it doesn't red shift so we would be seeing the waves exactly as they were when they formed, only more spread out because of the inverse square law of gravity.
Another great job Fraser. With hot staging, stage one is still thrusting at a reduced rate. Elon says the centre three engines will be at 50%. Also the mass to orbit is increased because of the increased momentum compared to non hot staging. Elon says up to 10% increase.
I’ve seen multiple examples of JWST and Hubble photos combined to cover a greater portion of the EM spectrum. What benefit, if any, would there be to having a “full spectrum” telescope with the necessary instruments to view any object from radio, through visible light, to gamma ray simultaneously?
What's the first image of the "Progress of flight" decal on the Virgin Galactic shuttle, under Icarus? Can't help thinking it should be a trebuchet, you know the first and best air launch delivery system. Look how far we've come 🤩
Question: If the universe isn’t infinite, shouldn’t we be picking up echos of gravitational waves that have bounced off of…something? I’m asking why don’t we have a bunch of gravitational wave data that we can’t explain? Or do we have that issue and I just haven’t heard about it? Thanks!
It's the same thing with visible light. If the Universe is finite and smaller than the observable Universe, then you'll see mirrored structures on opposite sides of the sky. We don't see that, so we wouldn't expect to detect mirrored gravitational waves either.
Over the next few decades as we gain ways of detecting gravitational waves at numerous frequencies, do you think we will be able to do a kind of gravitational wave spectroscopy? If so what kinds of questions do you think that would be useful for answering?
13:33 I would be willing to bet that dark energy and gravity will turn out to be caused by the same thing. The curvature of spacetime, or a stretchy 4d hyper-universe. I would put money on that guess.
I doubt that we'll find proper planets in the oort cloud -- because, even if they're slightly larger than earth, they're gonna be moving too slow to be able to 'clear their orbit' -- one of the current requirements of being a planet. You'd need something *huge* to be able to fulfill that requirement.
Are there Lagrange points between stars in the galaxy? And could they hypothetically be useful in the far future like energy efficient transit lanes for interstellar craft or some kind of research station?
Not trying to be a wet blanket but I don’t see why this detection of the hum is such a big deal. I mean it’s totally interesting but there are other things in this very video that seem more important to me. It’s interesting what makes it into the mainstream and what doesn’t.
That's okay, we find different concepts fascinating. I love that they're able to use pulsars as a method for detecting the mergers of supermassive black holes. It's such a cool and clever idea.
@@frasercain Oh! I’m not saying this isn’t interesting, I’m curious why this is such a breakthrough. It’s very clever, the detection of carbon cations in nebulae seems more important? Again really trying not to downplay these observations. It’s still very cool.
I agree that detecting CH3+ is a huge deal because of its role in life. But I tend to get more excited about the development of new techniques. So this is akin to the development of spectroscopy that enabled the discovery of the CH3+. I personally put more emphasis on new techniques since they enable so much.
@@frasercain I hadn’t thought of it like that, that makes sense for sure. However this isn’t as easy of a thing to do as something like spectroscopy. This detection all told took about 25-15 years of observations right? Of course that will change in the future. I guess we’ll just agree to disagree, I suppose my millennial brain wants more immediate breakthroughs. Still love the channel and what you do, especially the news letter.
That's why they are calling it that for marketing purposes. They want you to associate the two and equate the importance of their detection with that of the CMB.
@@trucid2 yeah and that's specifically why I don't like it. I'm so generally opposed to all of the weird markety-BS like the hyped up thing on 「 extraterrestrial life 」 that ended up being an exaggerated report of an extremophile that can maybe use a bit of Arsenic It confuses and misleads people and doesn't accomplish anything and now we'll have to tweeze apart which background we're talking about
@@smenor I'm with you there. I'm skeptical about the whole gravitational wave detection thing altogether. There are too many shenanigans surrounding it to not be skeptical. I'm not convinced they've actually detected gravitational waves as other sources of the signals have not been ruled out.
This is so awesome! I need sigmas for the chance that they are right about their sigmas too. But no seriously I'm sure it's true because it's expected and surprising if it weren't so. Anyway, so awesome. I think I can feel the vibe.
Nope. I took space terms and time terms, mashed them together and checked to see which domain names were available. Even in 1999 it was hard to find domain names. :-(
I'm curious can we use this info to filter out the background noise in the universe to help us communicate longer distances and with less interference? or listen for aliens.. but mostly the first part lol :) because as we get closer to a nuclear engine we will go further and further out and need faster and faster communication speeds over long distance :)
If Pluto doesn't get to be called a planet, then these Oort cloud objects won't either. One of the conditions to be called a planet is "having cleared their orbits from other objects", so the Oort cloud planet-sized objects, that roam in not well defined orbits, cannot be called planets!
Question: Could dark mass/matter be 'condensed' hawking radiation from the gazilliontillionillion of micro black holes at the beginning of the universe? Can hawking radiation even 'condense'? How could we measure it? Pissin in the wind...🤷🏻♂️
My idea so I get to name it! What I mean is, no one has claimed it so I'm officially calling, "dibs." Voyager 1 is now in Milky Way's interstellar time or "Mikey's Time." "V-ger's" message has sped up now that it's outside our suns time bubble or, "Terran Time." It will be faster still when "V-ger" sends a message from beyond the Milky Way's time bubble. Then there's Outside the Local Group time bubble. So on and so on until we get outside any influence and into the, "True Interstellar Time Standard." Or, "T.I..." ;-P Now that "V-ger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "V-ger" read time for as long as possible. They WILL show the flow of time speeds up the further away you get from any celestial bodies. Until you reach the Milky Way's time standard or "Mikey's Time." •Our sun's time bubble: "Terran Time" we know and have measured. •Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until V-ger is outside the Ort cloud .00007-.0007% faster, maybe. Just for reference. •Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference. •Outside any influence in the, "True Interstellar Time Standard." (or T.I...) ;-P This name is NOT up for grabs. The rate/flow of time is fastest here. (Time flows fastest here so it's best to use a motor boat and hold tight. Always applies when you're in T.I....) ;-P A minute is a minute in all. It's the rate/flow I'm talking about. Heck, rivers of time flowing differently might explain dark energy and dark matter. The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time." Pass it on, please and thank you
We never know what things will have a practical use. That's the very definition of exploration. If we're trying to refine things to be practical, that's called engineering. Think about transistors, lasers, and more, all of these were just blind exploration in the beginning. When you think there's away to communicate at the speed of light through solid objects just by moving stuff, you can imagine there'll eventually be a practical use for it.
@frasercain I appreciate that. I was more wondering if the waves are directional enough in the current set up to aim other telescopes or anything like that.
Off course is lfollows logically that if the whole universe is gravitationally bound together then there would be very low strength gravitational waves suffusing all of it??
Hey Fraser you know it’s ok to say Starship was a partial success right? I truly don’t understand the obsession with binary success / failure talk. And that’s generally mainstream media. You’re channel is much better than mainstream. No need to say “I’m not going to get into that” as if it’s yet another binary political issue. It’s currently at experimental stage. And it did take off. Lessons were learned. Thanks for your channel!
I wonder what sized/massed object would effect life on earth? meaning ..Like what if a mercury massed planet came into our system on the same path/speed as oumuama.., would it be 'enough' to disrupt any orbits to the point of ending life on earth? Or would it need to be closer to the size of jupiter to do any real damage? i guess universe sandbox could answer this but i dont have it
Question: could a star have ever gotten massive enough that the force of gravity could overcome the force of a core collapse, leaving a supermassive star with a stellar remnant at its core?
SpaceX originally planned some weird half somersault centrifugal separation. Problem with that was that they would have to do that with boosters off. And... Until you have climbed onto a stable orbit, any time you are not thrusting ~ 1 G upward, you are loosing altitude (or upward velocity) that you "paid for" with fuel that you will have to "re-spend" once you continue accelerating. It is more fuel efficient to accelerate continuously, and at the maximum rate that your ship/payload can withstand.
I flew through the Oort Cloud a few weeks ago. ..wait.... Sorry, it was just a regular cloud we flew through, my wife has just told me. 'Blue Stratos' she says it was. What's the Oort cloud, she's askin'.. Women, eh? What ARE they like!
I am still waiting for them to clue in that Atlas (Uranus) and Khaos (Neptune) are labeled incorrectly. Ironically they got Caligo (Sedna) right. Uranus is the sphere within Atlas’ orbit except Gaia obvi she came first. That’s the sphere Atlas is holding.
Who them? And what do you mean? Uranus was the husband of gaia, both son and husband, atlas was a titan, ordered by Zeus to keep heaven and earth apart, (Uranus and gaia) Chaos was the time before creation, Uranus was castrated by Chronos, are you mixing stuff together?
Perhaps we need a new Generation of Stars. The 1st are the ones we know that produce heavy metals, The 2nd and 3rd have lighter elements. Perhaps a 4th Generation of stars much closer to the Big Bang, were degenerative matter once abounds.

Does the Oort cloud intersect with any other solar systems version of the Oort cloud?
Every time a star gets within a couple of light-years of us, yes.
Its All Good! / Interaction....
If Pluto doesn't get to be called a planet, then these Oort cloud objects won't either. One of the conditions to be called a planet is "having cleared their orbits from other objects", so the Oort cloud planet-sized objects, that roam in not well defined orbits, cannot be called planets!
Uh, Navigational Beacons????
Yes, pulsars make fantastic navigational beacons.
Could gravitational waves explain Déjà vu?
Question:
Could dark mass/matter be 'condensed' hawking radiation from the gazilliontillionillion of micro black holes at the beginning of the universe?
Can hawking radiation even 'condense'?
How could we measure it?
Pissin in the wind...🤷🏻♂️
Wibbly wobbly, timey wimey. The Doctor wasn't wrong.
Gonna blast the booster from the top and not build a flame trench so it gets blasted from the bottom too? 🤔
They'll figure it out... eventually.
My idea so I get to name it! What I mean is, no one has claimed it so I'm officially calling, "dibs." Voyager 1 is now in Milky Way's interstellar time or "Mikey's Time."
"V-ger's" message has sped up now that it's outside our suns time bubble or, "Terran Time." It will be faster still when "V-ger" sends a message from beyond the Milky Way's time bubble. Then there's Outside the Local Group time bubble. So on and so on until we get outside any influence and into the, "True Interstellar Time Standard." Or, "T.I..." ;-P
Now that "V-ger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "V-ger" read time for as long as possible. They WILL show the flow of time speeds up the further away you get from any celestial bodies. Until you reach the Milky Way's time standard or "Mikey's Time."
•Our sun's time bubble: "Terran Time" we know and have measured.
•Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until V-ger is outside the Ort cloud .00007-.0007% faster, maybe. Just for reference.
•Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference.
•Outside any influence in the, "True Interstellar Time Standard." (or T.I...) ;-P This name is NOT up for grabs. The rate/flow of time is fastest here. (Time flows fastest here so it's best to use a motor boat and hold tight. Always applies when you're in T.I....) ;-P
A minute is a minute in all. It's the rate/flow I'm talking about. Heck, rivers of time flowing differently might explain dark energy and dark matter.
The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time."
Pass it on, please and thank you
I appreciate learning for scientific knowledge, but does gravitational wave detection have any practical use?
We never know what things will have a practical use. That's the very definition of exploration. If we're trying to refine things to be practical, that's called engineering. Think about transistors, lasers, and more, all of these were just blind exploration in the beginning. When you think there's away to communicate at the speed of light through solid objects just by moving stuff, you can imagine there'll eventually be a practical use for it.
@frasercain I appreciate that. I was more wondering if the waves are directional enough in the current set up to aim other telescopes or anything like that.
Not these ones, but the stellar mass ones, definitely
Off course is lfollows logically that if the whole universe is gravitationally bound together then there would be very low strength gravitational waves suffusing all of it??
Hey Fraser you know it’s ok to say Starship was a partial success right? I truly don’t understand the obsession with binary success / failure talk. And that’s generally mainstream media. You’re channel is much better than mainstream. No need to say “I’m not going to get into that” as if it’s yet another binary political issue. It’s currently at experimental stage. And it did take off. Lessons were learned. Thanks for your channel!
So there are countless billions of rogue planets going every which way through the galaxy. That's a little scary.
I wonder what sized/massed object would effect life on earth? meaning
..Like what if a mercury massed planet came into our system on the same path/speed as oumuama.., would it be 'enough' to disrupt any orbits to the point of ending life on earth? Or would it need to be closer to the size of jupiter to do any real damage? i guess universe sandbox could answer this but i dont have it
Question: could a star have ever gotten massive enough that the force of gravity could overcome the force of a core collapse, leaving a supermassive star with a stellar remnant at its core?
But why did SpaceX choose hot staging? And how does that increase payload to orbit?
SpaceX originally planned some weird half somersault centrifugal separation.
Problem with that was that they would have to do that with boosters off.
And... Until you have climbed onto a stable orbit, any time you are not thrusting ~ 1 G upward, you are loosing altitude (or upward velocity) that you "paid for" with fuel that you will have to "re-spend" once you continue accelerating.
It is more fuel efficient to accelerate continuously, and at the maximum rate that your ship/payload can withstand.
@@NullHand Oh, so they do it to minimize gravity drag. Thanks!

what would happen to the first person to die on the moon should they epect to havr some sort of system to bring them home.
Leave me there.
@@redcat9436 don;t have the excess space for people to visit it.
I flew through the Oort Cloud a few weeks ago. ..wait.... Sorry, it was just a regular cloud we flew through, my wife has just told me. 'Blue Stratos' she says it was. What's the Oort cloud, she's askin'.. Women, eh? What ARE they like!
I am still waiting for them to clue in that Atlas (Uranus) and Khaos (Neptune) are labeled incorrectly. Ironically they got Caligo (Sedna) right.
Uranus is the sphere within Atlas’ orbit except Gaia obvi she came first. That’s the sphere Atlas is holding.
Who them?
And what do you mean? Uranus was the husband of gaia, both son and husband, atlas was a titan, ordered by Zeus to keep heaven and earth apart, (Uranus and gaia) Chaos was the time before creation, Uranus was castrated by Chronos, are you mixing stuff together?
@@doncarlodivargas5497Uhm...
You got some Greek sauce on that Roman MythoSalad you ordered there.....
Perhaps we need a new Generation of Stars. The 1st are the ones we know that produce heavy metals, The 2nd and 3rd have lighter elements. Perhaps a 4th Generation of stars much closer to the Big Bang, were degenerative matter once abounds.
Maybe those are the primordial black holes, if they exist. Technically that classification works. 😀
How much light does a single photon produce?
The energy depends on the wavelength. Shorter wavelength the more energy.
Well space is a fluid so of course it has waves.
No mummy, no !
