The History of Antimatter

[barito7]

well....welll....well....CARRY­ ON then

[chillichomper]

B.S. You can't create enough antimatter to do anything useful with it. This might be a blessing in disguise because we'd probably blow ourselves up!

[E65Hawk]

@chillichomper Not, yet! wait 10 or 20 years. We'll figure it out

[StrikaAmaru]

@E65Hawk There are anti-protons trapped in the Van Allen belts, and around Saturn; they're produced by high-energy particles collisions. About a year ago, I found a PDF describing how an antimatter trap could be built to mine it...

But it was several km. across, even if it was mostly empty space, so not many chances of seeing one built.

[dimiTTar]

I just started thinking... If electron's opposite is positron (same characteristics but opposite charge) and proton's opposite is antiproton, THEN how this works with neutron (neutron-antineutron)? 'Cause neutron doesn't have a charge... Or does it have anything to do with the charge?

[enriqueDFTL]

I wondered the same thing...

[howieqd]

i think it is not only the charge that's making them "anti----" but it's their behavior as well. Even though neutron has no charge, its mirror image (antineutron) bonds with antiproton to make its nucleus making its behavior different from neutron.

[jesterlady]

This is the answer: Protons and neutrons get their charges from elementary particles called quarks, which are only found within them. In Anti-Neutrons, the antiquarks, though they still equal out to be neutral, have the opposite charge than each would on a neutron.

[shamsael]

It's not just charge, it's also spin. Neutron is spin 1/2, antineutron is spin 2.

[scorchinscorpio]

antimatter confirms the fact that by nature, everything has a positive and negative side to it.

[jesterlady]

except for the imbalance between matter and antimatter in the universe ^_^

[acidmatar]

a movie is coming out called angels and deamons but dunno if its same as the book ...hope it is though

[dellsprospects2]

need to take this stuff off internet...why don't we just build the weapons for the whole freaking WORLDWIDE Terrorist network to watch...jeez, people...

[Firemanrob87]

This stuff costs 300 billion dollars per milligram, and would cost 100 quadrillion dollars and 100 billion years to make for a gram with today's technology. SO this is not possible for terrorist, nor can they transport the stuff. Also you need a particle accelerator to produce it (~4 mi in Circ.).

[bantalboy]

wow the video is so amazing but to me it is too boring

[vampiregirlx3]

Really cool.

Read Angels and Demons.

[JCo62484]

Yeah that's where I first heard about "anti- matter" and it got me interested in the whole concept. It really is a good book.

[Clausfarre]

This makes me think of the Bizarro world Seinfeld episode

[Cyberphysics]

Thankyou for this - adds another dimension to my lessons on antimattter!

[Outlawed86]

have they actually collected samples of antimatter?? or are they going to?

[Dudekunle]

yes we have samples that were created using super-colliders

[yiotos]

wouldn't the particals die from the atoms in the air?

[james0music]

the accelerators operate within a vaccum, so when the anti-particles are produced - there is no air about for them to collide with an "cancel out" with.

[SkepticalZombie]

Very neat video, I genuinely learned something from this. Thank you.

[kurtilein3]

thanks for uploading, its short but contains some important knowledge.
