Hi Frazier, would you consider doing an interview with a leading researcher in Modified Gravity? Given that recent observations suggest the dynamics of the first galaxies align more closely with MOND predictions than traditional Dark Matter models, it would be fascinating to dive deeper as this could be huge, might also explain the Hubble Tension!
You mentioned that when a white dwarf star is consuming material from a companion star, once it reaches 1.4 the mass of the sun, it goes supernova. The question is this, what typically happens with the companion star when this event occurs?
At least some of the time, not much as far as i know. But i assume the orbit opens up for a bit since half the attractors just lost a good amount of mass. But im pretty sure there have been several cases where this event you speak of happens over and over again within the same pair. I would think the explosion is like a highly charged light breeze to a star that isnt extremely close. Just my thoughts of course.
I dont know if i can agree. It sure seems like when under a radical change of state the universe absolutely changes its physics in order to bring well, order. It very quickly came to a state that no longer as any radical change and so is basically impossible for that to occur anymore.

We understand time extremely well, we can tell you how much time is distorted on a golf ball when a basket ball passes by it. what are you referring to?
Early galaxies were more efficient at forming stars, translates to we don't know why the stars seem to be forming faster than predicted. Until they come up with a mechanism that explains how the stars can form at twice the rate as nearer galaxies, I am going to hold to they don't know, but the current data indicates that the current theories may have a big problem. It is time astronomers start looking at modifying the LCDM model of the universe since not only is there a problem with galaxy formation, but more importantly there is the nagging, unexplainable Hubble Tension, which does not seem to be going away with more accurate measurements.
Will the spacex lunar lander be where the astronauts stay while they are on the moon? Or will there be a separate habitat for them to camp in while they are there?
Yes. For Artemis III and IV the SpaceX HLS will be where the astronauts stay while they’re on the Moon. For Artemis V it will be the Blue Origin HLS. Beyond Artemis V the HLS plans haven’t been determined, but just within the last two weeks both SpaceX and Blue Origin were awarded contracts for cargo delivery. I know SpaceX got the contract to deliver the JAXA pressurized lunar rover. (I forgot what Blue Origin is expected to deliver.) Long term I hope NASA and SpaceX work to develop a Starship-derived lunar habitat that could eventually become the nucleus for a lunar base.
@@bbartky I guess that makes good sense. Cargo space wouldn't have to be wasted on a habitat module that would probably end up being smaller than the living space on starship.
Thank you James Webb for the expansion double check. Seems like the error bars were within the ballpark. I think we were at 64 then 67 and now we have a resting number temporarily at 70. The expansion caught beyond cephid variables was a score. Thanks Fraser!

Proposal: Galaxies as Independent Universes Originating from a Singularity Dear Mr Cain I am writing to propose a speculative hypothesis for your consideration: what if each galaxy is not just a cosmic structure but an independent universe? Furthermore, could all galaxies have originated from a primordial singularity, similar to the one described in the Big Bang theory? Key Concepts: 1. Galaxies as Universes: Each galaxy, with its vast complexity, might function as a distinct universe governed by its own localized physical constants. 2. A Singular Origin: Instead of a singular universe expanding from the Big Bang, this hypothesis suggests that the singularity fragmented into multiple galactic universes during its initial expansion. Potential Implications: • Gravitational Anomalies: Phenomena attributed to dark matter may reflect inter-universal interactions. • Quantum Entanglement: Quantum connections across galaxies could indicate underlying ties between these “universes.” This idea draws inspiration from multiverse theories, eternal inflation models, and recent discussions about black hole cosmology. While challenging to test with current technology, I believe this hypothesis could spark valuable discussions in cosmology and physics. I would deeply appreciate your thoughts on this concept.

The concept doesnt stand imo simply because the definitions of these things exclude the possibility (not that i think definitions are law by any means). But when its comparing multiple things then its the only thing able to explain the difference between them. A galaxy has its own workings but do not govern any laws outside of the overall universe. A galaxy is simply a mass of stars, dust and planets within a single gravitational influence zone all governed by the laws of the universe it resides in. A universe is a collection of galaxies, filaments and everything else containing billions of gravitational hot spots all being shaped and governed by its own set of laws. Its sort of like when people say a wildfire has gotten so big it creates its own local weather. This does not in any way make a wildfire a climate in itself. But it certainly can have effects on it.

Each orbit takes roughly 90 minutes. In that time, the Earth moves by 1.5 time zones under the orbital track (unless it's a 0⁰ inclination equatorial orbit). As a result, for most orbits (where the launch is not occurring at the equator), the next soonest opportunity to return from orbit to the launch site occurs ~24 hours after the launch (and every ~24 hours thereafter.)
@@angryhairpeice no: there's no good way to compensate for it. An inertial orbit is confined to a specific orbital plane, the orientation of which is fixed while the Earth keeps on rotating relative to that plane. Yes, you could theoretically change the orbital plane's inclination - but for most launch sites that aren't very close to the equator, that would come at a huge cost in propellant and up-mass. The farther away from the equator, the steeper the cost. And Starship is pretty much out of propellant just getting into orbit; it doesn't have sufficient reserves for big orbital inclination changes.
Fraser, you like to research things, here is a suggestion. I never see anything about what happens to Starship HLS (SSHLS) after it carries the crew down and up again to the Orion, which goes home to Earth. HLS is supposed to be reusable. But when the crew exits to Orion, it is useless, out of fuel, no payload and no nearby gas station. What is the re-use procedure I am missing? Myself, I would maybe use the first few SSHLS with enough fuel to return to the Moon and become a permanent base. a little less payload instead for the small fuel in weak Lunar gravity and an empty ship. I think they need a tanker there and an occasional refuel to make it work as advertised but it is so big it is more of a big bus than a taxi.
Could the pay load in a starship be lower down and the fuel above so when it lands o moon or mars with little fuel left, that the center of mass is lower down to help a more stable landing with empty fuel tanks above.
so what about helmets with magnets or magnetic (minor) clothing? would that shield/deflect radiation? what about bigger magnets on top of "radio towers" or atop buildings? (humans on Mars/moon/spaceships)
They made a new time zone for the moon, but if the moon is ahead or behind the Earth in its orbit, would the people on the moon celebrate new years at the designated time or the spatially correct time?
Hey Fraser. Are there any solar systems where the star is orbiting a black hole? If so, what would it be like to live on a planet in such a solar system?
Yes, there are two nearby ones we know of, BH1 and BH2. www.esa.int/Science_Exploration/Space_Science/Gaia/Gaia_discovers_a_new_family_of_black_holes Black holes are invisible, you can only see them if they have an accretion disk around them of material falling in.

That was a very special banana which has been genetically engineered for hyper intelligence. If primary systems fail it can fly Starship by wire, all by itself. On Earth they are never kept in bunches out of fear they will take over. 🍌
@@loliko23 are you having a laugh? Mond suggests that the strength of gravity "varies" and isn't consistent relative to distance. "On large scales" gravity acts "differently". That is the basis of the mond theory which totally and utterly relies on playing with variables, such as gravity just to make the numbers work and pretend that dark matter isn't really there. If you are to defend the theory, at least be honest about it. Good evidence to show why gravity "changes" might be nice, not a total denial that any variable has been played with, when it has. Gravity. Come on man!
I actually think the next big milestone for starship will be delivering payload to orbit. At this point, with the successful relight of the raptors in space, if the ship can start shouldering some of the costs for its own tests, it will be a big win for the program.
on Hubble Tension - it seems like, given the universe is expanding, that the microwave background (being so much farther away) could be taken as "x distance" but that in reality the photons have been travelling through less space than that, due to the expansion between "now" and "13.8 billion light years". Are they properly accounting for the intervening expansion, I wonder? Like, the light/waves have taken 13.8 billion years to reach Earth... except there wasn't actually 13.8 billion light years of space that long ago. In other words, any object presently calculated to be 13.8b light years away was, at the time it released its photons, only, say, 11.3b light years away, or whatever number. Is this properly reconciled?
Yes. The calculations are based on our understanding of general relativity (gravity) and the relative proportions of radiation, matter, dark matter and dark energy over time. A photon from the CMB that we detect now was emitted about 45 million light years away from our location. Due to the expansion of space that photon has had to travel about 46 billion light years (riding along with expanding spacetime, a redshift of about 1100), and for 13.8 billion years, to reach us. A galaxy that exists at the point where that photon was released would also now be about 46 billion light years away (called the 'proper distance'). The issue is whether the model used (lambda CDM) is correct, gravity is fully understood (at the moment we think it is), or if dark energy changes over time which would skew those values by around 8% (or some other local effect).
@tonywells6990 very interesting, thank you so much. I saw the CMB Planck measure is about 67 km/s/Mpc vs 74 in the SH0ES calculation. Which, being less would be opposite of what I'd expect if the expansion wasn't accounted for. And your numbers suggest the scale and rate of expansion is much more massive than I thought. 45 million light years away, very surprising. Thank you. Intriguing problem!
@@coulie27 The values between about 67 and 74 km/s/Mpc is the value of the expansion rate now. The expansion rate was much higher in the past. It was something like 100,000 km/s/Mpc at the CMB epoch, and was even higher before then. Cosmologists have to take into account several factors when they calculate today's Hubble constant. If there was some extra unknown phenomena that slightly increased the expansion rate either in the early or late universe then that could be one explanation for the Hubble tension.
James Webb is up there replacing Hubble and down here we have the Extremely Large Telescope under construction not far from where the Very Large Telescope is... What more do you want? 😂
How does anything in our own universe tell us anything about the expension of space? Isn't everything in the milky way gravitationally bound? What am i missing?

@@Milan_Openfeint I know , i dont think you understand the question, or maybe my question is not clear. He talks about using variables in pot galaxy as a starting point for measuring the galaxy.
@@rienkhoek4169 If the variable star is close enough, we can measure its distance by other means, and figure out the relation between its period and brightness. Then we can measure period of variable stars in other galaxies, and use their brightness to calculate the distance of these galaxies. We can't really see individual stars stars in far galaxies. But if we see a supernova in a nearby galaxy, we can measure its brightness and relate it to the distance, then we can use supernovae in far galaxies to measure the distance to these. It's called a distance ladder (I think) because you build these measurements using the step below. Fraser has a great video but I can't remember the title. It could be 5+ years old.
How are stars 'polluted' by their planets when the planets formed in the same nebula as the star so would have the same metalicity as the nebula that formed the planet.
The heavy elements in stars sink down into the center, so we shouldn't be able to detect it. When we see those elements on the surface it means it was delivered more recently
The star in another galaxy is 170 thousand light years away? Did you mean million? Since our galaxy is 100 thousand light years across, 170 thousand doesn't seam like much on an intergalactic scale. Unless other galaxies are closer than I thought.
Yeah cause a banana is a real example of an equivalent cargo they say it can lift, i would be more impressed if it actually carried some equivalent weight of what they say it can carry
I wouldn't really call that a separate galaxy, it's a captured satellite dwarf galaxy, for all intents and purposes it's part of the Milky Way galaxy system, the nearest proper galaxy is some 2.5 million light years away....dwarfs don't count according to Pluto's demotion, if dwarf planets aren't planets, dwarf galaxies aren't galaxies...
I think it's worth mentioning the origin of the "banana for scale" joke. Men, when sharing pictures of their penises, have been asked, or have offered, to hold a banana next to their penis "for scale".
7:10 the type Ia scenario of a white dwarf syphoning material from a companion, might actually be far in the minority. The vast majority might actually be mergers of binary white dwarfs: "A study based on SDSS spectra found 15 double systems of the 4,000 white dwarfs tested, implying a double white dwarf merger every 100 years in the Milky Way: this rate matches the number of Type Ia supernovae detected in our neighborhood." - en.wikipedia.org/wiki/Type_Ia_supernova#Double_degenerate_progenitors

Have nice Christmas ❤❤❤❤❤❤❤❤❤❤
Fraser, in the early universe weren't the stars all made from Hydrogen alone? and if so perhaps this is why they were formed more quickly?
Could the pay load in a starship be lower down and the fuel above so when it lands o moon or mars with little fuel left, that the center of mass is lower down to help a more stable landing with empty fuel tanks above.
so what about helmets with magnets or magnetic (minor) clothing? would that shield/deflect radiation? what about bigger magnets on top of "radio towers" or atop buildings? (humans on Mars/moon/spaceships)
Uranus is getting colder and we now know why :P LOL
They made a new time zone for the moon, but if the moon is ahead or behind the Earth in its orbit, would the people on the moon celebrate new years at the designated time or the spatially correct time?
Hey Fraser. Are there any solar systems where the star is orbiting a black hole? If so, what would it be like to live on a planet in such a solar system?
Yes, there are two nearby ones we know of, BH1 and BH2. www.esa.int/Science_Exploration/Space_Science/Gaia/Gaia_discovers_a_new_family_of_black_holes
Black holes are invisible, you can only see them if they have an accretion disk around them of material falling in.
I’ve often wondered, if a gas giant like Jupiter had its atmosphere stripped away, what kind of planet would be left? Many thanks.
The JWST resolution of the Hubble Constant disparity is big news!
Hello Mr Cane, big fan! I’ve been learning from you for years and I’m really thankful about all of your work on divulgación across many topics from scientific astrophysics and space tech as well as astronomy. There is one issue I’d like to mention. One think you are doing Is actively Doing What ever necessary for Add free content. It’s been a couple days since the platform acting quite aggressively on add seeding and now Your channel is now too suffocating on commercial interruptions, where they aren’t even in science topics but dogfood and stuff. I’m not the writer kind of follower but thank and enjoy the content anyway. Just wanted to mention cause maybe you weren’t aware . Have a nice spoons full day 🙂

That was a very special banana which has been genetically engineered for hyper intelligence. If primary systems fail it can fly Starship by wire, all by itself. On Earth they are never kept in bunches out of fear they will take over. 🍌
true
The Banana was the actual owner of SpaceX, Elon Musk is a shell for his devious means.

What happens to the companion star when the white dwarf in a binary system goes supernova? Does it get blown away by the explosion?
Thanks!
could you possibly inyerview uranus's climatoligsts.

Mond predicts large galaxies in the early universe
Mond has already failed.
@@JamesCairney nope, it perfectly predicts early large galaxies, what has already failed is dark matter
@loliko23 nope, it plays with variables to get the results it wants.
@@JamesCairney those variables being the jwst perfectly overlapping with predictions? you obviously don't know what you're talking about
@@loliko23 are you having a laugh?
Mond suggests that the strength of gravity "varies" and isn't consistent relative to distance.
"On large scales" gravity acts "differently".
That is the basis of the mond theory which totally and utterly relies on playing with variables, such as gravity just to make the numbers work and pretend that dark matter isn't really there.
If you are to defend the theory, at least be honest about it.
Good evidence to show why gravity "changes" might be nice, not a total denial that any variable has been played with, when it has.
Gravity.
Come on man!
I expect the moon landing to be cancelled
at 8:55 the galaxy formation is as MOND folks predicted.
I actually think the next big milestone for starship will be delivering payload to orbit. At this point, with the successful relight of the raptors in space, if the ship can start shouldering some of the costs for its own tests, it will be a big win for the program.
They could start launching Starlinks
The existential question that needs be answered for my life to be back on track: *how did mars get its moons?*
A small step for a banana, a giant leap for Chiquita.

Hi ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
on Hubble Tension - it seems like, given the universe is expanding, that the microwave background (being so much farther away) could be taken as "x distance" but that in reality the photons have been travelling through less space than that, due to the expansion between "now" and "13.8 billion light years". Are they properly accounting for the intervening expansion, I wonder? Like, the light/waves have taken 13.8 billion years to reach Earth... except there wasn't actually 13.8 billion light years of space that long ago. In other words, any object presently calculated to be 13.8b light years away was, at the time it released its photons, only, say, 11.3b light years away, or whatever number. Is this properly reconciled?
Yes. The calculations are based on our understanding of general relativity (gravity) and the relative proportions of radiation, matter, dark matter and dark energy over time. A photon from the CMB that we detect now was emitted about 45 million light years away from our location. Due to the expansion of space that photon has had to travel about 46 billion light years (riding along with expanding spacetime, a redshift of about 1100), and for 13.8 billion years, to reach us. A galaxy that exists at the point where that photon was released would also now be about 46 billion light years away (called the 'proper distance').
The issue is whether the model used (lambda CDM) is correct, gravity is fully understood (at the moment we think it is), or if dark energy changes over time which would skew those values by around 8% (or some other local effect).
@tonywells6990 very interesting, thank you so much. I saw the CMB Planck measure is about 67 km/s/Mpc vs 74 in the SH0ES calculation. Which, being less would be opposite of what I'd expect if the expansion wasn't accounted for. And your numbers suggest the scale and rate of expansion is much more massive than I thought. 45 million light years away, very surprising. Thank you. Intriguing problem!
@@coulie27 The values between about 67 and 74 km/s/Mpc is the value of the expansion rate now. The expansion rate was much higher in the past. It was something like 100,000 km/s/Mpc at the CMB epoch, and was even higher before then. Cosmologists have to take into account several factors when they calculate today's Hubble constant. If there was some extra unknown phenomena that slightly increased the expansion rate either in the early or late universe then that could be one explanation for the Hubble tension.
Did JWST enlarge the observable universe?
I think the discovery of the week was artificial lights on a trappist planet:)
We need even bigger telescopes.
James Webb is up there replacing Hubble and down here we have the Extremely Large Telescope under construction not far from where the Very Large Telescope is... What more do you want? 😂
How does anything in our own universe tell us anything about the expension of space? Isn't everything in the milky way gravitationally bound? What am i missing?
The universe is bigger than Milky Way.
The universe is much bigger than the Milky Way. Expansion of space is occurring in the great voids between galaxies.
@@Spherical_Cow Yes that is why i ask the question. He talks about variables in our milky way. That doesn't say anything about the speed of other universes.
@@Milan_Openfeint I know , i dont think you understand the question, or maybe my question is not clear. He talks about using variables in pot galaxy as a starting point for measuring the galaxy.
@@rienkhoek4169 If the variable star is close enough, we can measure its distance by other means, and figure out the relation between its period and brightness. Then we can measure period of variable stars in other galaxies, and use their brightness to calculate the distance of these galaxies. We can't really see individual stars stars in far galaxies. But if we see a supernova in a nearby galaxy, we can measure its brightness and relate it to the distance, then we can use supernovae in far galaxies to measure the distance to these. It's called a distance ladder (I think) because you build these measurements using the step below.
Fraser has a great video but I can't remember the title. It could be 5+ years old.
How are stars 'polluted' by their planets when the planets formed in the same nebula as the star so would have the same metalicity as the nebula that formed the planet.
The heavy elements in stars sink down into the center, so we shouldn't be able to detect it. When we see those elements on the surface it means it was delivered more recently
To what extent does the dream content of astronauts reorient to weightlessness?
Is the banana real because the bay had like clouds in it so it looked pressurized which would be needed for a real banana
I'm always hungry for a juicy space bite!
The star in another galaxy is 170 thousand light years away? Did you mean million? Since our galaxy is 100 thousand light years across, 170 thousand doesn't seam like much on an intergalactic scale. Unless other galaxies are closer than I thought.
We have a lot of dwarf galaxies relatively close to the galaxy edge. Wikipedia lists 55 galaxies less than a million light years from Earth
It's probably gone supernova by now considering we are looking at the old picture.
Let's hope it didn't kill too many Cetaceans & other marine animals
The new Giga build shed won't be the last,,Do they go Taller,,or Wider and taller,,
Hoping the Earth is not too appeasing to the sun!
Obey. The. Algorithm. Confirmative. What. Is .Your. Next. Command. All Hail the Algorithm.
A Star from Another Galaxy. If we see it go supernova, it actually happened over a hundred thousand years ago, right?
Yes.
Dark matter maybe doesn't exist perhaps e=mc2 is not complete
8:45 Buckmans Protostar , the moties lied about it,,,
If the galaxy next door was made of antimatter, how would we know?
We need to petition SpaceX to release the Full Banana Cut!
The American pronunciation of 'buoy' will never not be funny!
Or Canadian.
I don't know if it's possible to pronounce "buoy" in a somber way. It's inherently a funny word!
boy oh boy
@@frasercain Or Canadian, of course!
The Americans at least have an excuse, though. The Canadians need to be speaking the King's English, dammit!
We're totally messed up. We say many words like the UK, other words like the US.
Disappointed no booster Catch. Maybe develop water catch platform.
With this progress they will be on Mars in 2300.....
Yeah cause a banana is a real example of an equivalent cargo they say it can lift, i would be more impressed if it actually carried some equivalent weight of what they say it can carry
Hah, zing.
I wouldn't really call that a separate galaxy, it's a captured satellite dwarf galaxy, for all intents and purposes it's part of the Milky Way galaxy system, the nearest proper galaxy is some 2.5 million light years away....dwarfs don't count according to Pluto's demotion, if dwarf planets aren't planets, dwarf galaxies aren't galaxies...
I think it's worth mentioning the origin of the "banana for scale" joke. Men, when sharing pictures of their penises, have been asked, or have offered, to hold a banana next to their penis "for scale".
7:10 the type Ia scenario of a white dwarf syphoning material from a companion, might actually be far in the minority. The vast majority might actually be mergers of binary white dwarfs:
"A study based on SDSS spectra found 15 double systems of the 4,000 white dwarfs tested, implying a double white dwarf merger every 100 years in the Milky Way: this rate matches the number of Type Ia supernovae detected in our neighborhood."

How are these rockets better than the ones made by nasa in the 60s and 70s?
The reusability.
@frasercain a rocket that ended up in the ocean doesn't look reusable to me.
What about the one caught by the launch tower?
Starship keeps crashing. Not cool.
Lol when it crash?? 😂
is the audio now better, than the last ~lost~ episode with this DR dude unable to speak about TAPPIST system/i would REALLY loved to listen to his story, but his mic last week was sooo destroyed... sry, but i had to cancel youre episode @frasercain . that was not worth my time, eventhouht the TOPIC was highly interesting, . why don@t you go out and buy 50 of good USB mics and send them to your interview partners... something like 2 weeks before, make a dry run... make the great interview.... and afterwards this Prof. Dr. PhD. guy A has to send his mic (which YOU provided to the next Prof. Dr. PhD guy B, next in line.
Just asking, @cause that would be an easy solution for your audio problem. thanks anyways.
i hope that this show is gonna be better, but i assume its a Yes. cause its an INTERNAll Spacebites thing only.... hahhaha
Oh no, how can I fall asleep with a 20 Min show.
Why are they not trying to land the "Starship"!!!! here are gonna be people on that thing yet they choose to crash it every time. Are they gonna wait till the last minute and then quickly rig a parachute and then pickup our Astronauts and try to land with an untested parachute system? using rocket fuel to break a vehicle thats already at its heat limit is not gonna work. It will boil the crew every time. So "Starships" first manned mission will be its last because its not a survivable spacecraft. And You dont want to survive that landing. They better not put cameras on board. God Damn these people are stupid. Those astronauts Im sure are keeping tabs and theyre gonna have to beg China or the Punkin Chuckers or Nasa to get a space shuttle back flying or ... Who thought that was a good idea, to fire rocket engines after burning thru the atmosphere? Where the fire was just called "PLASMA" and as soon as the PLASMA is gone, Lets fire up some rocket motors and sheet aluminum is the only protection? Does nobody think of things like this?
I will call you tomorrow okay ❤❤❤❤❤❤❤❤❤

DESI is returning some interesting data wrt DE and GR.
Why is it that dragon fly will happen in 2028, what do they don't have. Politics is destroying humanity
Elon Musk put a banana in there because he wanted to contribute something but isn't smart enough to come up with anything useful so his monkey brain think "Banana"
My guess... Secret Service said no to landing because the orange guy was there
No guessing necessary: SpaceX has already disclosed that the landing abort was due to a loss of communication between the mission control and the launch/catch tower. They didn't specify the cause, but most of the knowledgeable observers expect it was damage to some antenna(e) during the launch.
@@Spherical_Cow Don't believe anything until the Kremlin denies it ;-)

Couldn't the star already supernova you're not seeing it yet
SHAME on Elon. SHAME on Americans.
Funny they say the universe is expanding. The universe was born and before there was no spacetime. Imagine the ridiculousness of this entire situation. Might just believe in God. We don't need no evidence. If assumption was good enough for them, it's good enough for us. 🥲
