So how science know about protons?

[santisouth]

[Greenwolfdragon]

actually, i dont think weve even gotten to the point where we can see individual atoms, much less protons

@santisouth we can only just see blood cell's and we cant even see dna... now can you imagine how small atom's are? The only reason we know they are there is because of chemical reaction's and such.
