I answered your question. That's all. Do you deny that matter tends to clump together with other matter?

Mass attracts mass. That's gravity. Stating a little very basic science is a problem for you? I don't know what you have said that contradicts my definition of gravity. Nor do I have any idea why you think gravity is somehow relevant here.

You still haven't proven the earth is flat. You just continually yap about nothing : - D
