Feedback, one of the things that is really neat with your videos is that they are very educational. You explain rather complex things in a rather "simple"(take this the right way) so its very easy to comprehend for the listener or atleast with how my brain is wired.
straightforward is probably the more accurate way to say what you're thinking. academia is needlessly circuitous and the internet has been slowly dissolving the artificial barrier to entry
I love your work JMG. You are well on the way to having a million subscribers. I know that sounds hyperbolic, but you keep putting out great content and you have reached the peak now, so the 'snowball effect' is inevitable. You are doing everything right. When you "make it" and go far above, please remember me, I subscribed when you had like 716 subscriptions.
That’s awesome that you got JMG in your feed when he had such few subs. Truly an awesome communicator and if this was a TV show that existed when I was a kid, I would have hung on to every word.
This is one of the best channels I've found especially because the topics are detailed and discussed in a soothing tone. Perfect for casual listening while still being very entertaining
It's worth remembering that the idea of a black hole collapsing into a singularity is just one theory. All we know is that there's a region of space from which nothing can escape. Most models predict an infinitely dense singularity, but it's quite possible there's matter of very high density.
I can’t help imagining it as a kind of neutron star or whatever next step, I still think of it almost like a sun, but with so much gravity light gets stuck around it and eventually gets added onto the mass of the sphere but I can’t imagine it as an actual hole leading somewhere it just feels intuitively wrong. Like a black sun that light and matter can’t escape and it’s gravity field from being so dense is so strong it rips apart matter and reintegrates it into the black sun and that’s why it gets bigger and bigger. Instead of shining out like our sun it’s shining in because the gravity won’t let the light escape.
Thank you JMG, your channel is an absolute treasure. I hope you are doing well and that the passion you have for Space will continue on for as long as possible. Also, thank you for helping me wind down, relax, and pass out. 😁 The vastness of space and what can be learnt completely trumps my short and insignificant problems throughout life.😅
Your videos are amazing but the ending scares me every time I have one I have your videos in queue. I sleep to your videos while I learn at the same time. My only “negative” input is to lower the volume of the end or to change it. Much love.❤
The endings are the identical volume as the rest of the video. Check it with a waveform, it's perfectly industry standard normalization. What I do change is the cadence, which is what I've done in every video since I started in 2016. Were I to change it to please one listener, I'd have thousands complaining and wondering where liiiiiive went.
Hey JMG, are your books available as audiobooks? If not you should record yourself reading them and release them as such. You have a good voice for that sort of thing.
Can a white dwarf become a neutron thought they had surface nova explosions to get rid of excess mass, and if that fails it goes up in a supernova type 1a
I understand that eventually,in some cases, a star can burn it's fuel supply completely and leave behind nothing but a "cinder'. What would this cinder be made of? I find it difficult to imagine anything other than sooty carbon, but i'm guessing a star is a bit different than a fire pit.
Of course, stars aren't literally burning, like wood burns in air's oxygen. Stars fuse nuclei of lighter atoms into heavier ones in their cores. “Cinder” is a metaphor, the remnant of a stellar core, after a star has exhausted available hydrogen, H, and fused it into helium, He, after the rest of the exhausted star, its outer layers, have either dissipated or exploded in a supernova. The “cinder” is most often a white dwarf, sometimes a neutron star, or even, rarely, a black hole. Heavier stars can fuse helium into even heavier atoms, but for the most of the lifetime of a star of any mass, fusion of H to He is the main, longest lasting process, because it has by far the largest energy output per atom. Stars form from the interstellar gas, 3/4 H and 1/4 He, which were created in the Big Bang, with a dash of other elements, made in the previously exploded stars. All atoms in your body except H are made in stellar explosions and neutron star mergers. Carl Sagan once said: “The cosmos is within us. We are made of star stuff,” and this is not a metaphor! Everything on our planet, and even the planet itself, is made of the same star stuff. Watch videos 1 to 4 on star evolution, and 6 on star formation in this Launch Pad Astronomy's playlist, it's a very easy introduction into stellar astrophysics: ruclips.net/p/PLrAnGxL8nxOET_FfZinl5Z-JHrH41OpZ- The rest is optional, only these are essential. And the whole channel is amazing!
@~5:50, maybe dumb question, how do we know far away galaxies aren't made of antimatter? Voids around it so it hasn't encountered normal matter yet, or similar to that.
Italian language lesson: you say "panino" to indicate you're having ONE sandwich; the "o" at the end of a word indicates it's singular. Panini connotates more than one; the i at the end of Italian words indicates plurality, as in bambini, cannoli, molti, etc. So, unless you're having more than one panino, please don't say "...this panini..." Buon appetito.
You know this has me thinking a bit of the hypothesis of the proton decay. How exactly will things look when things start to decay? Will everything just start to be thanosed I assume?
5:06 antimatter is significantly more than flipping charge. It’s more like a mirror image of matter particles that are traveling backwards through time.
nah he's right. antiparticles are just the flipped charge counterpart to the respective particles. how are they moving backwards in time when we can create and measure them
First, I love your video's style, format, and content. At 16:05 you mentioned "Grey Goo" being related to a type of strange mater that converts regular matter when it comes in contact but I think you are mixing that term with something else, at least the Grey Goo I know of is related to run away nanotech (that's the grey part being made of in-organic atoms, i.e. metals and silicon) en.wikipedia.org/wiki/Gray_goo
if some of the galaxies are made of antimatter while others arent.... we could hypothesize that some of the voids are formed when abunch of antimatter galaxies merge with regular galaxies.
Very interesting and as per usual up my street at the moment. Great stuff and many thanks .Actually the really heavy elements are said to come from nothing less than a neutron star collision or some very large mass object . After iron a star actually dies its first life and what ever it is next makes all the elements after that but at the same time those elements only get released in a small percentage of the actual supernova the rest is the neutron star or black hole.
I was just a few hours ag discussing supernovae with my cousin, as well as my hope that a naked-eye one will happen in my lifetime. I missed out on SN 1987A (not even being born until 4 years later), and, knowing offhand that the last naked-eye supernova was nearly four centuries before that, given the timescales involved, I assumed that an interval of centuries was the case and that SN 1987A meant (statistically) I (most likely) missed my shot by a hair. Learning that they *should* occur closer to 50 year intervals and that we are long overdue for one makes me much more hopeful that one will occur while I am still here to observe it. Thanks JMG!
If you create Universe 25, Universe 25 will then exist. Cause will manifest effect. Shocking!!! But true. Everyone smugly and self-righteously creates Universe 25. And then endlessly and endlessly and endlessly complains that it exists. Yeah, right. Logic dissonance much? Universe 25 is what you all have been calling "clown world". And no, you can't Personal Opinion away Universe 25 and its inevitable outcome. Once Universe 25 has reached extinction phase, no one will be left. And no, humans aren't magically an exception to Universe 25.
(15:47) How could metallic hydrogen maintain it's solid phase of matter without the pressures that shifted it into that state? Can anyone please help me understand?
@@jimurrata6785 But when that "liquid" water, which is below the temperature required to phase shift it to a solid, is brought 1 degree into where it should be a liquid, it cannot be changed into a solid no matter how much you shake the container .. or introduce nucleation. The metallic hydrogen is being removed from the pressures that shifted it to solid, yet remains solid in the absence of said pressure. How?
I chuckled, but thought of the gold looking on from a dark corner of the bar utterly indifferently. "Meh, helium again ....". And then Argon showed up and it all went south like a villain from an old west movie. But in the end, nothing happened.
I believe all use of helium as a lifting gas (weather balloons and blimps in addition to party balloons) is around 1% of helium usage. They're using helium as a gas. Liquid helium is 1000x more dense, and every single MRI uses many liters of liquid helium. As just one example.
8:55 Giant stars are rare now most likely because they don't live long, so have long since gone through their shorter lifetimes. And there is less gas around, all through the observable Universe, to keep forming lots of new, giant stars. I don't have anything to cite for these ideas, but that is my guess.
I see those Jets firing out of black holes as Universal sized Matter Colliders. There's got to be some Serious funky stuff going on at the jet terminals.
Strange matter can actually occur very much so from a neutron star or pulsar. There are a couple candidate stars that might actually be composed of it. It actually is much more stable than normal matter but requires very exotic conditions to form. In fact is contagious form of matter. It will convert normal matter into it if it gets in contact with normal matter. Theoretically it could destroy the universe if it got out of a gravity well of a neutron star. Although it might take trillions of years….. Because of distance and range. Anyway I thought I’d point that out
Stars carry out fusion reaction in their cores. Stars are composed of matter that bends / curves space creating the appearance of gravity. So how does the energy released from fusion reactions counteract gravity? The presenter just said so at 7:50, but doesn't explain that mechanism.
One of your best recent videos--and the ME call-out was amusing too! To be honest there is no saying that 'Element Zero' _isn't_ neutronium. We know almost nothing about it, beyond the fact it is created by supernovas which would also fit. However if it were neutron matter then it would need to be meta-stable neutronium since the stuff can be picked up and manipulated. The 'Mass Effect' itself is really just another name for Anti Gravity mixed with some aspects of Doc Smith's Bergenholm-style 'free' or inertialess flight.
I’d love if you could arrange an interview with Stephen Wolfram. I’d like to hear you talk with him about his physics project, irreducible computation, AI, and whatever else. Thanks so much for the content you make. It tickles my brain.
Good news! I actually did interview him a few years ago, and it's entirely possible that we'll check in again as the world careens deeper into the development of AI. The RUclips algorithm lost it, as it does with any worthwhile content, so here's a link to the interview: ruclips.net/video/LpK1d8mTEhI/видео.html
Wait, so are the neutrons created in a neutron star the same as normal neutrons? Feels like they aren’t, because AFAIK, an electron is its own fundamental particle, it’s not like neutrons are just protons with an extra electron in them, right? They are composed entirely of quarks like other hadrons.
Your videos and knowledge help us to not go insane and loose our mind and sanity because of things we can't comprehend. One of the two Best RUclips channel about science, physics, cosmology and philosophy
Muon chemistry has been done before. I remember seeing a paper where they managed to make a molecule of H-He, by replacing an electron with a muon. It's obviously unstable, but weird that you can get away with it.
But doesn’t the equation for antimatter kind of say it regular matter traveling backwards in time? Sooo. There is an antimatter universe traveling the other direction in time? So its why we don’t see much of it. Idk. Just sounds right
The hyper nova is really interesting. Due to antimatter pair instability, gamma rays go out of control, causing more anti pairs to form and then annihilate, causing more gamma... turning the outermost layers of the star into a fusion core. The resulting explosion is so extreme it does not leave a black hole, or any remnant. The whole thing converts to energy, and simply stops existing where moments before were a massive star. Anyhoo, I've never heard of electro-weak burning, that's a novelty I'll have to checkout. The quark-gluon Star I always figured would be the ultimate degenerate star, and some physicists think that is what black holes actually are, so long as you can ignore the idea of a singularity or infinity renormalization stuff. Super compact degenerate matter would dip inside the schwarzschild radius. The fact that quarks cannot easily be obliterated, they just form new quarks when getting smashed apart, so it's a firm if degenerate pressure, unlikely to collapse by gravity... But then we might hit gluon degenerate matter
What if the idea that antimatter “annihilates with normal matter on contact” is not quite accurate. Is it true that “early in the universe most of the matter and antimatter annihilated,” or could it be possible that when matter and antimatter make contact, they result in creating dark matter and dark energy. The first law of thermodynamics tells us that energy can never truly be annihilated, it only changes form - from regular matter to dark matter? With the explosion creating dark energy, responsible for the acceleration of the expansion of the universe? Anyway, it's just a thought.

It can increase in density in this dimension and at its time of collapse it touches the time dimension
Planet Earth 🌏 escape is impossible because there is nowhere to " escape " to.
Not mathematically there isn't.
Are you saying black holes might not be black holes at all?
I can’t help imagining it as a kind of neutron star or whatever next step, I still think of it almost like a sun, but with so much gravity light gets stuck around it and eventually gets added onto the mass of the sphere but I can’t imagine it as an actual hole leading somewhere it just feels intuitively wrong.

Like the other person said, the result is usually just iron. You can sort of think of it as cosmic ash if you'd like, but that's just semantics.
Depending on the size of the star, it can be a ball of carbon and oxygen, a ball of oxygen and magnesium, or a ball of iron.

Best ever , well done John ☆☆☆☆☆
Fantastic stuff!
Your videos and knowledge help us to not go insane and loose our mind and sanity because of things we can't comprehend. One of the two Best RUclips channel about science, physics, cosmology and philosophy
It's lose not loose for fucks sake. Why is everyone doing this these days? Lose. It's lose. Not loose.
My favorite form of exotic matter is muonium, which is formed from an electron orbiting an antimuon and is capable of undergoing chemical reactions.
I saved Muonium for its own dedicated video. Very interesting possibilities in that one.
@@JohnMichaelGodier That'll be an instant watch. It's such delightfully weird stuff.
How is there a “shock wave” in a vacuum/space?
Question? A Universal sized Singularity, normal matter, size 1.0. A Universal sized Singularity, Anti-matter, size .75. What happens if they collide
Could controlled antimatter+matter annihilations serve as rocket fuel?
Muon chemistry has been done before. I remember seeing a paper where they managed to make a molecule of H-He, by replacing an electron with a muon. It's obviously unstable, but weird that you can get away with it.
I stopped watching a Skeptick video for this. Worth it.
Where's Tay Zonday? u seein this?
John, you are amazing. Always remember that
Well actually, everthing we see is light, which is made of Bosons, not the Fermions which atoms are made of...
But doesn’t the equation for antimatter kind of say it regular matter traveling backwards in time? Sooo. There is an antimatter universe traveling the other direction in time? So its why we don’t see much of it. Idk. Just sounds right
Aristotle hated the idea, but he was a bugger for the bottle.
Thanks JMG 🎉
Grey Goo? Love that topic lol
Here comes my existential crisis again, big time.
What if like two black holes 2 universes of opp charge smashed?
The more I learn about physics, the more I think these "scientists" are zealots with an unreasonable amount of faith in very dubious claims.
Yup
Between anti matter and fusion is QGP and there is (at least) research into using it for generating energy.
Dubious of the paradox of matter viewing matter suspiciously.
Please don't ever stop ending your videos with _"in which we liiiiive"._
"I am an instance of matter viewing itself suspiciously" indeed.
The hyper nova is really interesting. Due to antimatter pair instability, gamma rays go out of control, causing more anti pairs to form and then annihilate, causing more gamma... turning the outermost layers of the star into a fusion core. The resulting explosion is so extreme it does not leave a black hole, or any remnant. The whole thing converts to energy, and simply stops existing where moments before were a massive star. Anyhoo, I've never heard of electro-weak burning, that's a novelty I'll have to checkout. The quark-gluon Star I always figured would be the ultimate degenerate star, and some physicists think that is what black holes actually are, so long as you can ignore the idea of a singularity or infinity renormalization stuff. Super compact degenerate matter would dip inside the schwarzschild radius. The fact that quarks cannot easily be obliterated, they just form new quarks when getting smashed apart, so it's a firm if degenerate pressure, unlikely to collapse by gravity... But then we might hit gluon degenerate matter
I want them to discover tachyons, then hypothesise a star made out of them. Would it be a time travelling star? That sounds hard-core as hell! 😂
What if the idea that antimatter “annihilates with normal matter on contact” is not quite accurate. Is it true that “early in the universe most of the matter and antimatter annihilated,” or could it be possible that when matter and antimatter make contact, they result in creating dark matter and dark energy. The first law of thermodynamics tells us that energy can never truly be annihilated, it only changes form - from regular matter to dark matter? With the explosion creating dark energy, responsible for the acceleration of the expansion of the universe? Anyway, it's just a thought.
"Everything you see here is made of atoms"
Actually all tou see there are photons
Close your eyes or turn the lights off and knock on a table. There be atoms without photons.
John love your videos. I'm a big fan. Thank you. Your voice is like Morgan Freeman
Thanks Will! Be well.
