Very well then, in a planet say there is more energy availiable so it's a higher pressure realative to say, the sun so it's higher pressure is drawn to the suns lower pressure. When dealing with pressures it's more of a matter of semantics to say which is doing what, the end result is that the direction of travel goes from High -> Low. If I puncture my tire the air will escape into the atmosphere, you could say that it's the high pressure of the tire pushing out into the air but it would be just as accurate to say the lower pressure of the atmoshpere would be drawing the air from the tire equalizing it. Pressures equalize from high to low it's just semantics you're arguing over and you're missing the point.
As for space-time-energy THAT was my point. Every physical object is composed of energy and matter. What I'm saying is that TIME also qualifies as an energy. Energy is movement and that's what time alows us to do isn't it? Move? So as time moves along it sustains what we know of as physical reality. This forms into the traditional energies in physics and matter and what's left over is what we use to move forward in time, granted this is a large amount of energy compared to how much is devoted to matter and traditional energy. But there is a noticable difference and that difference creates the pressure imbalance.
