If gravity can bend matter, then how much gravity is needed in order to break glass?

I agree with John - this is a vague question. Without gravity stars and planets would never have formed. Indeed, life would not have evolved in the same way as it has.

Because we evolved in an environment with gravity, so we have adapted to it. . I like gotcha's answer too.

Without gravity everything would float off into space.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
