Re: Physics anyone?
if there was a big bang and equal(?) amounts of matter and anti matter were created, how did matter win and not get cancelled out by the anti matter?
this has always confused me. i did see/read an explanation for it somewhere, can't have made any sense to me tho as i'm still none the wiser.

Re: Physics anyone?
They don't cancel out unless they actually lmake contact do they?
It's like at the horizon of a black hole. Black holes emit radiation because at the tip of their horizons they produce matter and anti-matter, when the antimatter is absorbed, the matter "escapes" due to the difference between gravitational field strength on both sides of the horizon. This is known as Hawking radiation.

Having typed all that out, search that for a better explanation. I'm a noob to all this.

Some fascinating, if controversial, shit discussed by Dr Amit Goswami here. First hour or so at least, I haven't got through the whole thing.

The matter/anti-matter transactions aren't perfect there's "left-overs", the matter we see today as galaxies and solar systems is the result of those left-overs I believe is the current hypothesis.

yeah, so they say, but why? i've never heard an explanation that has made any sense to me.SignalRecon wrote:timmyyabas wrote:if there was a big bang and equal(?) amounts of matter and anti matter were created, how did matter win and not get cancelled out by the anti matter?

i'll check out that hawking thing pembroke. as far as i know the 2 are attracted to each other hence why they cancel out. i think particles of matter and anti matter can and do appear out of nowhere (1 of each, so while they have come from nowhere, they are equal and opposite, so it's allowed) then dissapear again almost instantaneously in space (everywhere i guess, not just outer space) as they recombine.

look up cp violation for more info

Re: Physics anyone?
those theoretical physicists need to come up with some better ideas then. lazy bastards. i'll check out the cp violation too.
edit - i guess how is what i was meant to ask btw rather than why. i know we don't know dick all about why the universe is the way it is.

this is worth a read ^ entitled Matter, Antimatter, and Why Are We Here? (CP violation may be the reason.)

Re: Physics anyone?
how and why are interchangeable words in glasgow, although its normally the other way about, people saying how instead of why.
i'll give that a read, will stick the pdf on my phone for when i've got nothing better to do on the bus or someshit.

Re: Physics anyone?
So the reasoning behind that is that you can create matter from nothing as long you create and equal amount of anti-matter, and that these "transactions" happen even in front of your very face millions of times every second on an infinitely small scale in even the void of space and the big bang was simply one of these transactions on a massive scale. After the creation of both of these things they both almost instantly annihilate each other however not completely, sometimes leaving leftovers in "existence"d-T-r wrote:Physics and science has generally always been a place to identify and understand the mechanics of How, but rarely the why.

A really good series to watch on this is called "Everything and Nothing" which aired originally on BBC but is easily found on the net if you dig.

Re: Physics anyone?
pretty sure i watched at, maybe a couple of times as i think it might have been repeated at some point. iplayer/factual/science and nature is where it's at. never enough science on there but, too much big cat diaries or whatever.
that professor elliott cheu has a couple of lectures on there too, checking the one about matter out now, will hit up the one about this next.
cheers for the link d-t-r!

edit - turns out that video is about the lhc and stuff i already know, hopefully the antimatter one will give me some new infos.

The Universal Nilpotent Rewrite System + the dirac equation are other theoretical areas of key interest as they seek to unify all of it (physics and biological systems)

Re: Physics anyone?
The bit in the 1st part of the series about them creating a map of the known universe shortly after creation by observing the cosmic background radiation on a sort of photo-sensitive plate blew my mind the first time I saw ittimmyyabas wrote:pretty sure i watched at, maybe a couple of times as i think it might have been repeated at some point. iplayer/factual/science and nature is where it's at. never enough science on there but, too much big cat diaries or whatever.

would also recommend this
http://hitoshi.berkeley.edu/neutrino/PhysicsWorld.pdf
basically another explanation for the antimatter/matter asymmetry. that article is a bit old but still a good read nonetheless
