NOVA scienceNOW | Ask the Expert | Antimatter Engines

Want your own question answered? Put it in a video and post it here on YouTube. We'll have NOVA scienceNOW's experts answer selected submissions. This is a rare opportunity, so come up with questions, make a video, and send it in.

Video questions will be selected and posted on the Cosmic Perspective page on the NOVA scienceNOW website and then be answered by our experts throughout the season of NOVA scienceNOW, via text on our website, with the last question being answered the day after the final broadcast, September 20, 2009.

nuclear reactor was invented before the nuclear bomb.

Neil, please visit Dallas and explain to John Wiley Price what a black hole is and the physics behind the creation of a black hole.

[quangluu96]

@humbemsishere Somehow u can connect two ends in space and go through it :), some people think Black hole are worm hole

[blenderpanzi]

But wouldn't you need the exact same amount of energy to produce anti matter as you would get out of it later? And the magnetic containment would need extra energy, so it isn't efficient at all!?

@humbemsishere with capslock

[NobleUniverse]

annoying music in the end.

[humbemsishere]

HOW CAN I MAKE A WORM HOLE?

[fasantupp]

And they have contained antimatter in a vacum and some magnetic fields at LHC, it's still not a complete vacum tho so small portions of the antimatter gets anihilated.

[fasantupp]

If i don't remember wrong it costs as much enegry or more to produce antimatter as the anihilation of it gives :/

[Capeau]

@derman077

There is no matter in most ppl their heads, so thats no problem

[Capeau]

and how about instead of finding a way to contain them, maybe find a more eficient way to produce em at location

[derman077]

So how do they get antimatter into the brain inside P.E.T scanners?
