Why OP's question in particular, is stupid? Enlighten us... Anyways, there's no stupid questions but stupid responders
i don't know how many have seen an apple fall from the tree but basically only newton asked himself ''why did this apple fell ?'' if someone else saw him asking himself that they would have said the same
Afaik, Newton wasn't the sole inventor of the laws of gravity, he mostly bundled others theories because they wouldn't dare to risk the repercussions by the church in their time.
but still his questioning changed a lot i'm not saying that's the question in the topic will change anything (about why it's well done not weldone)
what i'm saying is we live by ''why'' if you give someone a pencil and you told him ''we draw with pencils'' if he didn't ask himself ''why do we draw with pencil only ?'' he wont know what he can draw with coal and i don't know else the painters use these days to make paintings that gets sold for big money the point is ''why ?"
Why is green green and not brown !!!!! ? @ Newton .......... it wasnt an apple ........... thats the politiclay correct version ........... what realy happened ? = A pidgeon s**t on his head
