Scientists trap anti-matter

[BiscuitintheBasket]

Titanium occurs in nature, although combined with other elements. I believe for the man-made elements you need to go to the heavier elements past Uranium, I don't think they are stable enough to occur naturally.

On Earth. Important to point that out when talking about something occurring naturally. As some of the "man-made" elements on Earth have been found to exist outside of Earth.

Wouldn't they decay just the same if produced naturally in some star or something?

One of the reasons for going back to the moon is to mine Deuterium (heavy hydrogen). It's been found in very, very small amounts on Earth, but theoretically there's tons of it on the moon.



Edit: Actually, I think it's tritium they want to mine from the moon.

Close. The lightest "synthetic" element is Technetium, whih does ocur in nature but the most stable isotope has a half-life of 4.2 billion years, and as such, any remaining from the formation of the earth ould have decayed. Minute traces occur in natue from the decay of Uranium (as in about 1 part per trillion), but any technetium used now is synthetic.



I think there are about 5 elements lighter than uranium (technetium being the lightest at 43) that are synthetic.



As for anti-matter, it's existance was I believe proved, but they could never keep it from annihilation and "trap" it before.

There are tons of things created in some star that stay the element they are, just in a different state. The fact that "man-made" elements on Earth have been found outside of Earth (not just in stars), suggests that those elements can and will exist.

That's my understanding as well. This recent discovery allowed them to trap it long enough to do some measurements. Hopefully they'll be able refine their methods and first, have an easier time to create it and second, to trap it for longer so they can poke and probe it for more thorough investigation. How they'll do that, I have no idea.

So if the big bang theory created equal parts matter and anti-matter, and mostly all we can find is matter..... maybe that anti-mater just went the opposite way than the matter and someone directly on the other side of the universe there is a BIZARRO EARTH! RIGHT NOW SOMEWHERE RUUTU IS STALKING JAKO....





Seriously though, I obviously am not following everything this thread, but man is it good.

I believe thats actually a seperate theory where there are infinite universes. So aliens and shit might not only be from another planet but another universe as well.

Never really thought of it like that. infinite possibilities are possible when you think of different universes.

We alread talk about Jako and Ymono enough.

Or it could even be argued that Anti-matter went back in time from the big-bang, while normal matter went forward in time.

The existence of anti-matter was first suggested by physicist Paul Dirac, who tried to reconcile quantum mechanics and general relativity, sometime in the 1920s. Diracs equation could describe the electron at any speed, until then they had always gotten the wrong answers when it came to describing electrons moving close to the speed of light. The equation needs the existence of anti-particles to work and a couple of years later it was proved with the discovery of the anti-electron, the positron.



I don't think that there is any doubt in the physics world about the existence of anti-matter. Most models seem to require it. The big question, as the article states, is the baryon asymmetry, why there seems to be more matter than anti-matter in the universe.



All in all, an exciting breakthrough in understanding the fabric of reality itself.

I took it as, we were 99.99999% positive anti-matter exists, but this experiment makes it 100%. I always thought anti-matter was still theoretical prior to this experiment

If matter and anti-matter annihilate when they collide. Does that not go again "matter cannot be created nor destroyed"? also in theory is it not possible for the universe to simply run out of matter and anti-matter.

I think that one is super string theory. But I know there is a theory that there are infinite universes and every single situation has its own universe. Under that theory there is a universe that everyone in this thread actually plays for the chicago blackhawks and man we are good, Also Bri is the captain of the squad...and our best fighter.

I think the consercation of energy/momentum comes into play. Using normal mater, in nuclear fission the overall "mass" of the matter after fission is less than the atom that did split. The mount of energy released is thus calculated by E=mC².



Thus, I believe if a hydrogen atom (protium, for simplicity's sake) and an anti-hydrogen atom (anti-protium), annihilate each other, the amount of energy relesed is equivalent to the total mass of the electron, positron, proton, and anti-proton times C², which means that the energy/momentum is conserved.

Did WE trade KANE for TURRIS?

We one upped that, we DRAFTED TURRIS.
