iirc there was some stuff I read while I was in high school (I got bored, so I started into this topic back then) that although there are no white holes in this universe, there have been postulates that we live in a multiverse (many universes) which have in the past have also been referenced as "dimensions".

This leads us to 1 of 3 different possibilities (the first two of which I particularly like).

1) The dimensions are layered on each other like a stack of pancakes. These dimensions are perpendicularly aligned with the dimensions we know. The first dimension is the track that all the universes are stringed on which creates a wormhole from dimension to dimension. The second and third dimensions are the frameworks that hold our current universe scheme together. The forth dimension is the other track that we travel along.

because they are aligned perpendicularly, we are able to expand forever in 360 degrees around the center point of the universe, however, it will give the appearance of going on forever, yet each universe is shaped like a spherical oval (where we live on the outside of the pancake)...

We are linked to our universe/dimension and all the universes/dimensions are traveling like a train on the 1 and 4th dimensions (tracks). Black holes are the way to jump from one car to the next. Now, even though there is no known white holes, it is not that they don't exist, but rather, they cannot be seen because light never hits them to reflect off of to us. Also, white holes are seen once one is in the worm hole since they are ways to escape.

2) Rather than being linked to our universe, we are linked to the 4th dimension, in this example; the 4th dimension is like a road. The universes are still stacked, however, the different choices we make force us to go from one universe to another (similar to how in back to the future, one choice could change everything) black holes and white holes are ways to go forward and backward in time.

Now even though Einstein said time travel was not possible, he did say that theoretically time viewing was possible. combining this view with the fact that in order to view something, light must be reflected off of it AND the particle theory of light which states that light even though it travels as a wave it has qualities of a particle (hence why it is sucked into a black hole) leads us to see that theoretically time travel should be possible and how we technically would be able to change our past mistakes.

this also creates a paradox, however, because (and we are going to presume God exists) if God created everything, and black holes are a way to go back into the past, then because of the black holes now and in the future, and the original white hole in the beginning, all the matter that was collected into the future was sent through the white hole which caused it to explode causing the big bang happened. because this happened, God never had to create anything since he already did, and the cycle just keeps going, he did however have to create a black and a white hole in the beginning... which brings us to our third possibility

3) WYSIWYG (what you see is what you get) and the first two points could just be mental masturbation and even though things can be mathematically proven, they are only possibilities and not realities

the end
or is it
