In my questions on gravity, I've come to the understanding that spacetime is really just time, and there is no need for space. Anything that requires a distance (for example the distance between two massive bodies for gravitation calculations) could just be a function of time. Can anyone show that there is a need for dimensions of space in spacetime?
To further explain what I'm asking. Michelson Morley proved that there is no aether? However, it is also correct that the Gravity B Probe mission Link proved that there is a bending of spacetime out there. So, if you subtract one from the other, it seems to show there is no space in spacetime.
It seems to me that the only thing required for gravity to work is the time dilation caused by a massive body. We talk about the bending of spacetime, as if it is a 4 dimensional thing. We talk about gravitational waves as ripples in spacetime, but are they really only waves in time? We can see time dilation at work. But can we see spacetime dilation? Can you show me how the dimensions of space are required for gravity?
Here is another way of putting it. There are objects floating around in the universe. The only thing connecting these objects to each other is time, rather than something called spacetime.
I hope that this clarifies the question.
