I think there is no such thing as anti-matter. That tunnel they built is just a water pipeline.

On the atomic scale, they do tend to attract towards each other (last I checked). Exotic atoms have been made that replace an electron with an anti-proton, and it has been observed that the anti-proton will sink into the positively charged nucleus to annihilate. Larger lumps may have differing results, however.

I'm still waiting for the day we can determine the gravitational properties of anti-matter. I find myself convinced that anti-matter may in fact be naturally repelled by matter. Though, should we be creating a big lump of anti-matter here on Earth, or try to find something massive already in space, like an Anti Black Hole or Anti Star? How do we detect an anti-gravitational field (negative space-time curvature) when photons seems to interact equally with matter and anti-matter?

Part of me thinks that matter and anti-matter wouldn't attract each other, and may in fact repel each other to prevent perpetual annihilation. They wouldn't work like everyday magnets, as we'd normally presume.Perhaps the big bang really did produce symmetrical amount of matter/anti-matter, but because of anti-gravity the two naturally separated. It would help explain why there seems to be so much matter in the [observable] universe, as the anti-matter would be somewhere else.

So antimatter consists of positive positrons and matter with negative electrons. Want they be attracted to each other?

i like this videos. I find them pretty useful for undergraduate students willing to study physics and know more about it. well this is something new i just learned ! thanks a lot Fermi Lab !

I like how he is wearing a Yin Yang shirt to represent matter and anti matter

Cancel out... not exactly. When matter and antimatter contact each other they annihilate one another. That's the actual scientific term, by the way: annihilation. It's a good word. All of the mass they contain is converted into energy all at once, and they contain a lot of energy. A LOT.
ProgHead777 . (el 01/06/13 a las 2:06 pm)
Put it this way. If you had 1 gram of matter (about the size of a paper clip) and 1 gram of antimatter (same size) and you combined them so that all of their atoms contacted each other at the same time, they would explode with 3 times the energy as the atomic bomb that destroyed the city of Hiroshima at the end of WWII. Let me say that again more simply: with an amount of antimatter equal to the weight of a paper clip, you could destroy an entire city.

This video still didnt actually explain what antimatter actually is, just how it's produced. D+ at best
