I wasn't claiming to be correct in my perception of the subject, merely stating my understanding of it. Which is, of course in violation of the PF Rules. Sorry.

Sorry for being vague. For what its worth the link cleared things up a lot. If the forum is not for sharing and building understanding, then what is it for? (I didn't ask for any replies to exclude mathematics).

So you are saying that you can describe space as an asymptote with massive objects intersecting it, and curving spacetime around them? could you explain the second part of your point differently?

So the inverse square law is accepted by general relativity as well as Newtonian gravity? Does this mean then that spacetime is never truly uniform, and that it's limits could be a result of the mass of the universe curving it?

Yeh I knew a bit about gravity propagating at 'c', but I am asking if, mathematically or otherwise, every object exerts a gravitational force on every other object in the universe. This is also taking into account truly negligible magnitudes over vast distances.

I thought anthropomorphising was a more accurate way if asking, but yes, I was asking if gravity is limited in range.

Are all objects gravitationally aware of every other object in the universe?

With regards to the Matter Creates Spacetime arguement. I am no professional physicist (im only studying Advanced Higher Physics at high school), but to me, it seems silly to assume that spacetime would be created independently from matter and energy. My logic being that an object must have...

We have a basic concept of time (a passage between two events). I believe it is a result of human perception. The best way to describe a system and it's changing values is to compare the starting state to the end state. Hence, we percieve this change as time. In response to your second point: I...

.I would define time in relation to the change in objects . If an object moves from point X to point Y, the difference in it's state between the two points could be described as a product of the time passed. For example, a neutron moves from point X to point Y. At point X it has a value of 1...

Photons have no mass, so it is impossible for them to accelerate. This means as soon as they are created, the travel at 'c'.

I was thinking a bit about gravity. As is known, Physicists have yet been unable to unify the Theory of Relativity (describing gravity) and Quantum Theory (decribing the other three fundamental forces). As mass is a measure of a system's energy, the force of gravity (presumably carried by...
