Hybrida":3cb45c8j said:
Because sci-fi is fond of adding "nuclear" or "photon" or "quantum" to anything to make them sound cool.
Even so, antimatter and photons aren't a seperate thing. Anti-matter collisions that convert all matter involved into kinetic energy, create photons.
Anti-matter itself isn't anything special; it's just... anti matter. It's abundant and everywhere. But colliding anti-matter with matter causes annihilation of both resulting in some crazy shit (though have to be careful of leaping from the realm of quantum physics to the realm of sci-fi; everything here is only a theory).
I believed that matter + Antimatter = Universe explodes. Not true, but not impossible. :grin:
NASA experiment with Antimatter. They calculated that a tea spoon of antimatter will equal to an explosion over 800 megatons. A few grams could blow up a whole city. It's to dangerous test, but it would make nuclear weapons look obsolete.
NASA trying to find way to use antimatter as a energy source, but they are too scared to use the stuff. I don't blame them.

they've only managed to create a few atoms of antihydrogen and even less antihelium, and i'm pretty sure they're annihilated within a few milliseconds or something
it's extremely difficult to create and is currently valued as the most expensive substance in the universe (one gram of antihydrogen is over $60 trillion i believe)
it's incredibly interesting stuff, actually. makes me want to become a quantum physicist or something :specs:
oh god i'm turning into hybrida ;-;

When matter and antimatter touch they are "annihilated" and turned into energy (i.e. a photon); while this is a relatively large amount of energy it is certainly not the end of the world, especially considering both matter and anti-matter are abundant to the Universe (according to the theory of quantum mechanics).
The "large energy thing" you talked about is the Large Hadron Collider (and come on, everyone and their mother knows about it and... the halluximatoric Hybrida doesn't o.O). It collides single photons with each other. Not antimatter. Nothing in fact to do with antimatter; they are trying to create a higgs particle by colliding "real" photons.
What you are talking about is colliding a particle with it's corresponding anti-particle, which would create one photon or anti-photon. NB: I may be wrong! But it would still only create one of them. When they talk about getting energy from antimatter, or creating antimatter weapons, we are talking a HUGE amount of antimatter (relatively speaking) - more than one or two particles which is what is used in such CERN tests as the LHC.

Actually, the large underground experiment related to antimatter is a large underground pool of pure water loaded with sensors. The theory is that, since several theoretical substances related to antimatter would simply pass through the earth with little to nothing in the way of slowing them down, they'll have a better chance of detecting them if they try it deep underground, basically filtering out a lot of other shit that could get in their way.

According to a TV show my dad was just watching, the explosion of Krakatoa was 13,000 times bigger than the explosion of the nuclear ordnance we dropped on Hiroshima. 13,000 times bigger. I guess mother nature kicks the ass of everything when it wants to, including nuclear weapons. What say you, Hybrida?
When you get to those numbers x000 times means relatively nothing. Making nuclear bombs bigger doesn't make them any more of a threat; a nuke that can blow up a house is enough to get a government worried enough to do what you want them to do. The gov arent gonna scream around going their nuke power levels! are over 9000 megatons!, they'll scream around saying "omfg they have nukes" in general.
