Antimatter - General - Facepunch Forum

[QUOTE=Rubs10;21371087]Hasn't it already been stated like elevenety times that there could be planets and such made of anti-matter? It seems people have the wrong idea about anti-matter. It's [I]exactly[/I] like matter. But our matter just has opposite charges that explode when they come into contact with anti-matter.[/QUOTE] Stated doesn't mean it's true. I'd like to see some sources.

Another interesting fact about antimatter - it was first discovered by Paul Dirac, who just noticed that his equations predicted it. [url]http://www.awesomestories.com/assets/paul-dirac-discoverer-of-antimatter[/url] How fucking cool is that?

[QUOTE=Pepsi-cola;21371355]There could be but they wouldn't last long. Any matter that meets it's opposite instantly turns into a massive amount of energy, with the greater leaving it's leftovers.[/QUOTE] You're not looking at the bigger picture. It's not just planets that could be made of antimatter, but entire galaxies. There could be entire portions of the universe that are composed of nothing but antimatter, with no matter within trillions of light years.

Make a thread about Dark matter and Exotic matter. Anti matter is exactly the same as regular matter, except Anti.

Xenophiles like Sully show up. Realize they can't fuck aliens because they would both explode. Hilarity ensues.

[QUOTE=archangel125;21370765]Here's the mindfuck. How do we know that we're not antimatter, and that the antimatter isn't truly matter?[/QUOTE] We don't matter is just what we've called the stuff that we're made of. If we were made of anti matter we would call it matter. And OP says that two main uses are weapons and space travel? Those uses do not yet exist. What about positron emitter tomography scans, which help to cure cancer? [QUOTE=Eudoxia;21371043](A 'while' being 1 gogol years. Gogol is 1 followed by a thousand zeroes)[/QUOTE] Its 1 followed by 100 zeros

Dark matter is better.

I love these threads. It's interesting learning about stuff that still baffles scientists. :hydrogen:

[QUOTE=rathat48;21371554]Dark matter is better.[/QUOTE] It isn't "better", it's different. Your comparason is illogical.

Oh god, this is so bad-ass, I always wanted to know about antimatter.

Antimatter galaxies , stars or planets have never been spotted. Sure, they [b]could[/b] exist. But you shouldn't take OP as straight facts (not saying that OP is bad). Also, read: "Antimatter galaxies, theoretically possible, but unlikely" [url]http://www.usatoday.com/tech/columnist/aprilholladay/2004-12-24-wonderquest_x.htm[/url]

What is produced from an anti-matter and matter explosion? Matter cannot be created or destroyed, only transformed. Does this same concept work with anti-matter?

If science has taught us anything, it's that nothing in this universe is impossible. Some things are just more probable than others.

I love science.

[QUOTE=Eudoxia;21371814]But matter can be turned into energy.[/QUOTE] But once it's energy, it's no longer matter. I thought if it's matter its always matter.

[QUOTE=Pepsi-cola;21371911]I never said it was impossible I just have doubts.[/QUOTE] Before considering the possibility of antimatter galaxies we should try to get an estimate of the amount of antimatter in the universe. :iiam:

[QUOTE=Zareox7;21371764]What is produced from an anti-matter and matter explosion? Matter cannot be created or destroyed, only transformed.

Looking at this diagram stolen from Wikipedia, you see a positron and electron interacting with each other (annihilating) and then turning into 2 photons.

[QUOTE=Eudoxia;21371043]Actually, matter and energy can be created spontaneously. Like OUT OF FUCKING NOWHERE :aaa: It's called the quantum vacuum: Every once in a while (A 'while' being 1 gogol years. Gogol is 1 followed by a thousand zeroes) a proton pops up. After an unimaginable amount of time... You pop up again, and the solar system, or even an entire universe :buddy: Isn't that shit just fucking cash?[/QUOTE] Actually, I am pretty sure that particles appear and dissapear alot faster than once in a googol years.

[img]http://upload.wikimedia.org/wikipedia/commons/b/ba/Feynman_EP_Annihilation.svg[/img][/QUOTE] So can you turn light back into matter then?

Is there any way for us to actually know if a given star or galaxy we're looking at is matter or antimatter?

It's awesome. But I think matter won, because ... well: Let's just say matter is "-" and anti-matter is "+", so combining minus with plus equals minus.

[QUOTE=Eudoxia;21371937]Before considering the possibility of antimatter galaxies we should try to get an estimate of the amount of antimatter in the universe. :iiam:[/QUOTE] I'd assume half is matter, half is anti-matter.
