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.
@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.)
How do we know the universe is only matter? Would the light be different from an anti-matter star? There may be an equal number of matter galaxies to anti-matter galaxies, and since the distance between them is so massive, they never combine. and we never notice
@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.
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!
@TheJFKWahoo The energy is released in many ways, but we see it as heat. The "Angels and Demons" movie/book was right, from a physics point of view. [As the video showed us, it is technically impossible to make a lot of antimatter, but if a gram of antimatter >>DID<< exist, goodbye Vatican!]
Antimatter is just the opposite of matter and, when combined with matter, releases a lot of energy. Other than that, it's kind of ordinary. You could make an anti-universe of antimatter.
@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.
Wow this was awesome!!!! You need to bring out more videos like these!! I'm a science teacher and love to show my students these videos explaining this more complicated topics.
When the universe began, weren't matter and anti-matter uneven? If they cancel one another out some matter was left behind to become what the universe is today, right?
@ilee9624 Yes...this is the fundamental mystery to which he is alluding. Matter and antimatter were made in equal quantities. However something made for ever 10,000,000,000 antimatter particles, there were 10,000,000,001 matter particles. The 10,000,000,000 annihilated, leaving the 1 leftover matter particle. From that tiny excess, the universe began. There is proof of this. If you count the number of photons in the universe from this annihilation, it is far more than the number of protons.
time traveling not real... hmmm we'll see about that!

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

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!

@franalappies Are you aware of the other video he put out regarding the Higgs boson? My understanding is that this is intended to be a series.
You can see the other video on the fermilab youtube channel.
