Do science know why like electric charges repels and unlike attracts?

At the simplest level they do so because when charges were first contemplated, it was part of their descrpition/definition that this was so. Just as the origninal convention has an electron negative, not positive - the rule is entirely arbitary - making them positive would have very major repurcussions, but it would not ultimately make any difference to the understanding of science. On a higher level, you are in the realms of sub-atomic physics, some of it in highly esoteric realms of thinking.

another perspective: There is no "why" in science only "how". But that is possibly even more esoteric!!
