i'm an artist making my way through life, this site seems neat.

Adult subjects and jokes may occur but no explicit porn. that's a DIFFERENT account.

for a hot moment we thought that they'd have negative mass or react negatively (as in, fall up) to gravity but we found out that anti-hydrogen does in fact fall down.

anyways we use antimatter elements in PET scans regularly.

Anti-elements are fun 'cus they're almost identical, until you strip a lepton or two and suddenly they'll go the opposite way in a magnetic field.

Or they find their counter parts and go "oops! I found my normal matter counter parts and FUCKING ANNIHILATED BOTH OF US IN MUTUALLY ASSURED DESTRUCTION"

Granted, it's more dramatic than it sounds. It happens all the time (I am not kidding, it does).

oh you can make much more fucked up stuff than anti-matter atoms
my favorite trick you can pull is being able to make an atom with a single electron orbiting a single antitau as the "nucleus". the antitau is short-lived and decays into an antielectron quite quickly, at which point they annihilate each other, but the fact you can do it at all is wild

Fun side effect of this is that we (pretty much) can't tell matter from antimatter at a distance. Like, there could be entire galaxies where antimatter predominates rather than matter, and we probably wouldn't know unless some physical stuff came from there to here (in which case we'd find out very quickly lol)

actually, interestingly, we know all the galaxies we see are matter!
The intergalactic medium is thicker than we expect - still about a particle per cubic meter. So if there was an antimatter galaxy next to a matter one, we would see a gigantic-as-hell glow between them as the antimatter and matter combine

Unfortunately, we don't see it ::< so, no antimatter galaxies

There's another way to tell, assuming there's also intelligent life there that can communicate with you & can perform particle-physics experiments, as detailed by a great MinutePhysics video: there's a very particular interaction of the weak nuclear force that violates both mirror-image and matter/antimatter symmetry, and with that you could communicate both left vs. right and matter vs. antimatter unambiguously
