so can we use this post for any useless crap? ill start by asking:
IF you imagine a strip of matel having coins punch out of it, the coins are matter/protons and the hole left in the strip of metal is antimatter/antiproton. At the start of the universe, there were masses of protons and antiprotons, and they a;ll wizzed around and when a proton and antiproton meet, they dissapear from the fabric of teh universe. we're lucky that the universe is around, cos for every billion antiprotons there were a billion+1 protons, and all the very small ammount of protons left formed the universe. what i dont get is; how do we know that this happened?
