## Main Question or Discussion Point

In most cases, we know why things happen. Protons can stick with each other because of the strong nuclear force. There's all kinds of forces and we know mostly about why they occur and how they are transmitted.

But I don't understand gravity. Why do objects with mass attract each other ? I know how to calculate it, but I cant seem to understand how it works.
