@Pds3.14 Says:
I think it would be pretty obvious that an antimatter comet was made of antimatter. Namely, that it would offgas antimatter that would interact with the surrounding low density gas and annihilate.

@Ice.wall7 Says:
How do we know what is made of matter or antimatter? CERN has shown that the only obvious way to discern them is by whether it reacts with matter. If we haven’t observed collisions of matter with a distant object then how do we know it’s not antimatter?
It’s extremely unlikely that much if any pockets of antimatter persists within the Milky Way. But it becomes less and less extremely unlikely as you go to other galaxies, other groups, other clusters etc.
Could an isolated cluster be composed primarily of antimatter and for any intelligent life that might be there, it would just be matter.
Please enlighten me if you can.

A while ago I had read a Sci-Fi book, I think it was written by John ringo, where the locals used antimatter and in order to store it they plunked a single anti hydrogen into the center of a buckyball and repeat ad nauseam. The charge of the buckyball completely surrounding the anti-hydrogen on all sides means that the electron Force pulling on it equally keeps the anti-hydrogen in the center. And when you want a bit of energy, you could legitimately burn the buckyball Dust to release a lot of energy. Is this actually viable?

Why do your hydrogens have 4 electrons?
@chrisbelkosky5466 Says:
Food for thought:
The universe is a big place [citation needed], if antimatter otherwise acts exactly like matter save for having opposite charge, who's to say we don't actually have a 50:50 non-homogeneous split with different clusters being predominantly one or the other?

how can you tell if an asteroid is made of anti-matter? Is it on fire? no? then its not antimater. There are matter particles flying everywhere all the time even in space, enough so you'd notice a reaction

Fun fact: one of the earliest mentions of this fact (3rd by my count) is in a blog post by my father from October of 2008, seemingly now only accessible through a link in an article found in a link to another article thrown into the wayback machine. The earliest mention I could find, sometime in 2006, was also sourced from his workplace Jefferson Lab.
Crazy how mind-genes fly, eh?
@gonpala Says:
so, you know how we called 2 things that look the same, act the same, have lived the same and are, basically, the same? just that, the same.
@jorgelotr3752 Says:
The theory I support about what happened to antimatter is pure statistics: this would be that when matter and antimatter were created, they did so while moving in certain directions, and some ranges of directions were richer in matter and others in antimatter, meaning that it's not that antimatter disappeared, just that parts of the universe are matter while others are antimatter, and we cannot distinguish between them, due to their identical properties, unless an antimatter body collides with a matter body and we manage to observe it.

@MooseBoys42 Says:
4:50 it doesn't need to generate more energy than the production cost to be useful. It can still be a fantastic fuel, having the maximum possible mass-energy density.
@timogul Says:
Well, "raw antimatter" might not be a good fuel _source,_ but it could be a great energy _storage_ device, if we could manage it. I mean, if you had a method of producing massive amounts of free energy, like a massive solar array, you could use that to produce anti-matter, and then store it, and use it as fuel in situations where there is _not_ abundant energy available. Again, assuming you could produce it at volume, and store it at volume, and convert that into energy in a productive way.
@petver29 Says:
Image universe is expanding really really fast (faster than light) while vacuum fluctuates between matter/antimatter. Then these fluctuations result in two separate universes one matter another antimatter and the two shall never interact.
@quinn-imagined-a-phox Says:
2:27 I love this example of everyday antimatter. So roughly every 75 minutes, an antimatter particle (positron) appears, and undoubtably annihilates with a normal electron to form light, which I believe would be 2 gamma rays that are at least 10^20 Hz in frequency
@JoeBorrello Says:
The concept of identical particles annihilating each other has been terribly abused by science fiction. If matter and antimatter Lazarus met, there would be an annihilation, but the same thing would happen if matter Kirk met matter Lazarus. It’s not that they’re the same person, it’s corresponding particles, such as a proton and antiproton or electron and positron. And only the particles themselves would be annihilated, not the entire universe.
@robertsteffler5155 Says:
Not to be pedantic, but given the number of people involved in making this video, I do think there should be more attribution in the description than "Created by Henry Reich".
@becavuse2274 Says:
Actually there is a difference between matter and antimatter called CP-asymmetry. Would be interested to see a video on that

Bananas have positrons in them... I heard it was the potassium. I even saw a video that showed them canceling out visibly to the naked eye. Not dangerous but it was just electron/positron one at a time which is crazy you could actually see it.
@ralanham76 Says:
Maybe way out in universe there’s a section of antimatter and those people are trying to figure out matter.

@think32 Says:
I wonder if there was a slight rotation in the early stages of the universe, during inflation. If so, could that influence the matter/antimatter ratio? Considering conservation of angular momentum, I'd imagine that at that initial scale, the rotation would have been insanely vigorous before slowing as the universe expanded. Just a thought...
@Honestly-Blunt Says:
The missing antimatter turned into the cosmic expansion acceleration. The only thing that explains the amount of energy.
@alan-aka-alum Says:
I don't know
@thimsbarkler5178 Says:
If a large enough cancelation happened would not Anti-matter and matter both be pushed away by energy released during the formation of the universe? It could be uniformly created but not Uniformly distributed? After all, the idea that an equal number of matter and anti matter needing to be created equally, suggests that the laws of physics in the Universe predates the Universe. And if so Newton's laws should also apply? Is it just the question of force of attraction between anti-matter and matter relative to the forces of the conditions of the early universe we're stuck on?
@randomnickify Says:
What if we are from antimatter and those random emissions are the real matter :D

@testdasi Says:
If an anti-particle is its particle but travelling back in time then there's no more 50-50 split issue. The time direction of our universe dictates that there would be more matter than anti-matter. The anti-matter-rich unverse is in our past, just like we are in their past.
@Aash1985 Says:
This looked like it would be an interesting video but the robot voice was just too grating, I gave up a few minutes in.
@katherinek6166 Says:
A bit of a correction, because the episode talked about electric charge primarily. Zero electric charge does not imply particle being its own anti-particle. Neutrinos and anti-neutrinos are distinct particles despite having no electric charge, because they still carry isospin. But photons and other neutral gauge bosons are completely neutral, so they are their own anti-particle. Technically speaking, "zero charge" is correct when it means, "no charge of any kind," but since only electric charge has been mentioned up to this point, it's kind of left ambiguous.
@fluffyboi999 Says:
Wouldn't a large mass of antimatter such as an asteroid be easily identified by the presumably detectable amounts of radiation emitted as bits of it annihilate with normal matter gas and dust?
