Is there any proof that gravity is an attractive force?

[Cubbie Boy]

Is gravity an attractive force of matter, or is it a universal force of expansion and pressure that exists in apparently empty space? Does matter attract objects near it, or does matter merely block gravity pressure on on any given side of a material body, giving the illusion that the matter itself is producing gravity?

LeSage gravity has been experimentally falsified for well over 100 years now.

Thanks for the reply. Interesting link, but a bit long, and beyond my ability to understand.

OK, the bottom line is that the idea has been considered, but doesn't match observations.

And with that, the thread is closed.
