What is Antimatter?

Fermilab scientist Don Lincoln describes antimatter and its properties. He also explains why antimatter, though a reality, doesn't pose any current threat to our existence!

Nice job! And now we know how they heat the coffee at Fermilab.

you never actualy explained what is antimatter, i mean how dose gravity work on it, why is an anti proton an anti-proton and not say an anti-electron all and where dose the energy go if you combine one anti-proton and one proton? all i understood is where it comes from and that we can make it useing matter, i still have alot of questions about antimatter but as an itreduction this was an Excellent video and meybe rushing too much with this will just get me comfused, This vedio is great!

time traveling not real... hmmm we'll see about that!

0:00 what? many things in sci-fi are theoreticlly quite possible, such as black holes, timetravel(through wormholes), and aliens. if you dont believe me, you are probobly an idoit.

For those of you who are interested, search for kaons and cp violation. They certainly do not explain the lack of antimatter in the universe, but they are a demonstration of what is required for there to be.

good video, congratulations.

@Pwn81 That was true only pre-Einstein. We now know that Energy and Matter are transumutable into one another. Now the sum of energy and matter cannot be destroyed, but matter can be destroyed as long as it appears as energy. (And vice versa.)

[Pwn81]

wait,how do you convert energy to matter because niether energy nor matter can be destroyed

[ZBlayde]

@TheJFKWahoo Antimatter is just matter with an opposite charge. For example, the antimatter electron would have a positive charge, and an antimatter proton would have a negative charge. When a particle collides with its antiparticle, a photon is formed, because photons have no mass. Antimatter particles are affected by gravity the same way as normal matter because gravitons are their own antiparticle. They have no real antimatter equivalent.

Wait a second, wouldn't the anti-photons from the anti-Dr. Lincoln have destroyed the regular video camera?! LOL

Nice touch on the ying-yang shirt... That's right, the Chinese discovered anti-matter long before modern science!

@vesman81 This is a good question, but luckily there is a definitive answer. Galaxies are beautiful and seem isolated, but they are actually surrounded by hydrogen gas. Antigalaxies would be surrounded by anti-hydrogen gas. Under these circumstances, the hydrogen and antihydrogen gas clouds would interact and the effect would be impossible to ignore.

Note it is still possible that there could be gobs of antimatter so far away that our telescopes can't see it. But we don't think this is true.
