Ever since the proof einstein's theory of gravitational waves the whole world of physics has been literally changed. So I have a question, if space is made of something like a fabric which reacts to gravity; what keeps it together why doesn't it 'tear' if the gravity is too much. Is there a 'thing' that is holding it together? For example a piece of cloth is held together by threads, etc. PS. I am just a 9th grader and I know the question is quite stupid. No Hate.
