Question

why isnt there an answer for "why" in science

Answer 1

What do experts really mean when they say "Science does not answer 'Why' questions"?

Here is what I tell my students. You ask a physicist "why do things fall?" and they'll possibly answer "because there is gravity". Then you say: but gravity is a theoretical conception derived from observations of how things fall; I have asked a why and you have answered a how". The wise physicist will remark that that is precisely the point and that science really works at best every time it has managed to transform a why to a how successfully and thoroughly.

A philosopher would turn this argument around I think, as follows: "why is there gravity?" "because things fall". Does this also make sense? Absolutely.
