If the universe is flat, suggested by a few cosmological theories, then it could not be described as having a bottom (existence of a minimum potential energy well or zero-point energy). Analogous to a sheet of blank edgeless paper, the universe will extend in all directions forever. In this sense, a bottomless universe is also an empty static or motionless universe.

The moment a point particle appears at a particular location of space-time, its nonzero mass will instantly induced a tiny curvature around the space-time fabric hugging this dimensionless but not massless particle. Simultaneously uniform motion and force of gravity are created by this infinitesimal indentation of space-time. In addition, an absolute, unchanging direction of time becomes established. Therefore, a bottomless universe must also be a timeless universe. Since space and time are interconnected, a timeless universe is also a spaceless universe where and when the value of the space-time interval of special relativity is certainly zero. Consequently, zero space-time intervals is necessary and sufficient condition for the existence of an inertial frame of reference and establish the principle of relativity that the vacuum speed of light is a universal constant of nature. Completing all 8 directional invariance properties, a bottomless universe is also topless, rightless, leftless, frontless, and backless. It is a universe without a past or a future. It exists in the present now and forever more.

It may be bottomless and topless but like a balloon being bloown up our universe could still be expanding and therefor not motionless or static, rather dynamic and propagating.

Prehaps what we confuse as depth is really a very long flat line?Looking along the line would Appear as depth,but would be illusional.

That's the widely accepted view. But since the center of expansion cannot be located, it needed a second thought about space and time directional invariance.

[Profpat]

Well we can even give it a third thought Antonio, because I know nothing.

Yes the direction points to where and what "IS"!

I am also working on a 4th thought or maybe should have been a forethought?

I keep thinking that if I follow this line long enough i'll see the back of my head?

[Profpat]

OK thats a good one Antonio

[mkirkpatrick]

Yes you would see the back of your head from the front,so to speak!
