White Holes and the Universe That Contains Them

I have decided to share my thoughts and conclusions about a universe that would contain White Holes. I do not hold a PhD in theoretical physics, but I became interested in this topic. This is purely a rambling about the conclusions I have drawn from it.

Gravity

I must first begin with gravity, as that is the biggest factor in the majority of these thoughts. Gravity is known as the consequence of the curvature of spacetime. In our known universe, gravity pulls on every mass contained within. Since gravity is pulling on the masses, at certain points, we conclude that it can form a Black Hole that pulls everything into it (including light). A White Hole is simply the reverse of that process, where it would push everything away from it (including light). This reversal is not "color," however, but the reversal of gravity itself. In conclusion, gravity pushes instead of pulls in this new universe.

Time

We know that as you approach the peak of gravity in a mass, the time dilation will slow down. Since the center of Earth is the peak point of gravity on our planet, we notice that the closer you get to the center of the Earth, the slower time seems to pass. In this new universe (that contains White Holes) it would be reversed. That would mean as you approach the peak point of gravity in this alternate universe, time would seem to slow. The difference here, however, is that when gravity is pushing instead of pulling, that peak point would be the entire outer edge of the planet and not a single point at all.

Planets

In our known universe our planet's structure is based off of how gravity behaves. For example, the outer edge of Earth is our "atmosphere," and the inner parts are the crust, mantle, and core. Now, if gravity were reversed, the structure would change because gravity no longer pulls toward the center point, but repels towards the edge. In this White Hole containing universe, the outer edge of Earth would be core, followed by the mantle, and the crust. Now this is very simplified, but I hope that's understandable.

I had heard stories of such a thing called a "Hollow Earth." I conclude that the description of that would be very similar to a description of Earth contained within a White Hole universe, where gravity is pushing instead of pulling. It's interesting, although, it's just something I've considered. The atmosphere would be the center of such a planet. Just my thoughts. It would make sense to me that the creatures and life would be held to the crust of the inner edge inside this White Hole universe's planet as the peak of gravity would be the spherical edge.

The graphic below is super inaccurate, and included just to help visualize my thinking. The image on the right is in a "cut-out" fashion. The circle shapes represent spherical shapes and is intended to make one assume it's similar to Earth, even though it may not be.
