Discuss Anitmatter.

Isn't that what is theorized to fill the void of space or something?

Einstein's a genius

has it even been proved to exist yet?

I don't think it's been proven, but it does answer some questions.

I don't know. It sounds like an alright record company, but I'm not sure they have enough records out to be judged at this point. I'm not so sure about all these indie labels these days. Some are good, but some are just crappy.

Yeah, those stupid recording companies that never get anywhere. I haven't even heard any of those songs.

Alright... here comes myncknm to straighten things out.

You all knew this was going to happen.


Oy... if it did then we'd all have died a million times over by now. Antimatter is like the opposite of normal matter. When a normal matter particle comes into contact with its antimatter particle, both are destroyed and the energy that composes them is released. That's called annihilation. When creating matter out of energy, you always get matter-antimatter particle pairs. If all the matter and antimatter in the universe were switched so that all the matter becomes antimatter and vice-versa, we would not be able to tell the difference. The antimatter particle of the electron, for example, is the positron. Where electrons have a negative electromagnetic charge, positrons have a positive charge. That's the most noticeable difference to us (besides the annihilation), that electromagnetic charges are reversed in antimatter.


Einstein did not discover or predict antimatter.


It's been proven alright. You even can go buy some if you really want to. It won't be cheap, though.

At the bottom of that webpage, it cites 35,000 Australian dollars per nanogram of antisodium-22. That's 27,601 in USD.

Yes... anyways, it's spelled "antimatter" people. There are only a few places where letters are capitalized within words: acronyms, some proper nouns (although I think it's stupid when a band titles one of its songs that way), and computer sciences (where sometimes spaces in a name will lead to errors).

I thought he has something to do with it.

Thank you, mynck.

And, yes, antimatter has been proven and is existing at this very second. Since it will annihilate when it comes in contact with matter, it is kept in a vaccum, hovering in midair by being trapped by two repelling magnetic fields. Yes, you can make a bomb out of it, it is theoreticly possible, but it would require enormous amounts of anitmatter, which is just too expensive.

But, it has the potential to be the best damned bomb ever made.

Yes, it does. But, it is not at all practical, or possible, with our current technology. To make an antimatter bomb would require more antimatter than exists on earth, and to make it would cost millions. It's also very rare, since it almost always anhiallates when it is created, unless experts are there when it forms, or if it was naturally contained in a magnetic vaccum. Or we could send a probe into space, where, theoretically, if you exit the universe, there will be a universe of antimatter. But, if the probe touches the anitmatter universe, the entire univese, including ours will anihallate. To get there, however will require a probe to travel to the end of the constantly expanding universe, go faster than the speed of the expaning universe, and exit time. Or we could keep on collecting forming anitmatter on earth for the next trillion years, which by the time, we will have enough to make a bomb. But by that time, the sun will have gone out, and we might as well have colonized another planet, which might not even have antimatter.

From my limited understanding of quantum field theory and stuff like that, getting matter to exit spacetime would be like getting a wrinkle to leave and exist outside of a sheet.

Theoretically, if the universe is expanding, it has to have an end. So, to reach the end of the universe, one must travel faster than the expansion of the universe (speed unknown) once one touches the end of the unverse, one will be atomized, and recreated into an alternate universe, which is made of antimatter. But, since you are matter, the anti matter universe would anhiallate.

Makes sense. I've given everything I know on antimatter.

Not necessarily one that can ever be reached. Say there was some extreme time dilation at the edge of the universe. That would mean that the closer you get to the edge, the slower time goes for you (so that observers from other places would see you as going slowly). Then no matter how fast you go, the expansion of the universe would go faster.

Define "atomized."

What force would be capable of effecting this recreation? And about the universe consisting of antimatter instead of matter, our universe has much more matter than antimatter because of a tiny imbalance in the weak interaction--the weak interaction being a force much like electromagnetism, except that it allows particles to change into other particles--where matter is created just slightly more often than antimatter when particles decay and other whotnot. This happens as time passes. As more time passes, more particles are created that don't have any antimatter counterparts. Therefore, if an universe existed that was made of antimatter, that'd either mean that our laws of physics don't apply there or... actually that's all it could mean. Or maybe another universe came and dumped a ton of antimatter into that universe. Something weird like that.

Or, just enough antimatter to completely balance out your matter. Not the whole universe. That'd be insane.

according to the dictionary

1. To reduce to or separate into atoms.2. To reduce to tiny particles or a fine spray.3. To break into small fragments.4. To subject to bombardment with atomic weapons.

Interesting. Why?



The universes are not meant to be exited. You would be taken through a space (of nothing, as was before the big bang) and your atoms would be spilled into the antimatter universe. However, before the atoms bond, they would be anhiallated.



That's what I meant. Or else, Boom. And, about your physics thing, there would be matter made, but immeediatly anhiallated.

If it cost millions, even Monaco would have an antimatter bomb

The universe is defined as being anywhere anything in that same universe can access. If a probe could access some "antimatter world," then according to the definition, that world would be part of our universe.

You cannot "touch" another universe. Furthermore, you are theorizing based on the multiple universes theory, which hasn't been, and based on its own nature can never be proven or refuted. Furthermore, how do you expect to actually "choose" this particular universe out of an infinite number of universes if in some crazy way you were able to "access" the cosmos?

If a probe exists time it will not exist. That's like asking a cube to exit space... it is defined in space, so it does not exist outside of it. A probe is defined in spacetime, so it cannot exit spacetime. Furthermore, who says there is a "warphole" at the theoretical "edge" of the universe to take us to your supposed "antimatter world"?

How can you make a bomb out of a record company?
Earth doesn't have antimatter either, AFAIK. We have labs that can create antimatter.

I agree, but that reminds me of that one book, "A Wrinkle in Time" (had to mention it ).

But it also forms naturally.

The same thing happens at a black hole due to its gravitation. Space and time get stretched out, so what you observe as a short time or a long distance would appear to an outside observer to be a long time or a short distance.

But there's no "meant to be" in physics. There's only what does happen and what doesn't happen. Atoms cannot exist outside of space. AFAIK, atoms are not distinct objects floating around in space but better understood as being a part of space, much like a wrinkle on a sheet of cloth. And why atoms, anyways? Why not quarks and electrons, which are currently understood as the most elementary particles that make up atoms?


Yes it does. Not exactly in very large amounts though.... Beta decay of an atom results in an antineutrino, I'm pretty sure. And cosmic rays provide enough energy to create an antimatter-matter particle pair.

So you're saying there is a space at the end of the universe that has gravitaional pull far out of proportion to it's size, like a black hole.

No, I don't mean gravitational pull. I was thinking more like--well, if space ends then time has to go with it, right?

No, time can exist where there is no matter.

Time can't exist where there is no space. That'd be like having an object with a width but without a length.

Well, technically Serebii was right in saying time can exist without matter, because matter != space. But he was also off-topic because you mentioned space disappearing with time, not with matter. So bleh.
