True, if one is not curious. But KNOWING which it is could greatly impact our understanding of the physical universe and how it works. And the more we know about it, the more we can manipulate it.

With all due respect, I don't think you're getting the point, here. Gravity is a force, which can be defined as either a 'push' or a 'pull', depending on how one chooses to define you +/- signs. The difference is a matter of convention. Newton's theory says it's an attractive force. That's as specific as it (or any other field theory) can get.

I don't think I was getting the point. I think you are correct.

My point, however, is that we don't know what we don't know, and finding out whether it is push or pull could have ramifications of which we are not aware - yet.
