Answer to Question #100880 in Astronomy | Astrophysics for Richard Davidson

Question

If the big bang is considered a point of infinite mass and density wouldn't that make it like a black hole. Or as I am proposing a white hole. And if that were true couldn't the observable universe be all the matter that was expelled from the opposite side or white hole if you will. Furthermore it would explain why the observable galaxies are distributed in such a homogeneous and isotropic manner. Also this may be the reason for the environment of such high energy and low entropy in the early stages of the universe. However due to the time dilation of gravity involved when dealing with black holes the possibly ongoing emissions from the white hole would go unseen by onlookers due to the loss of energy before the light or radiation waves ever reached us.

Answer 1

According to modern conceptions in the fields of astronomy, physics, and cosmology, white holes are still hypothetical objects. Few researchers and scientists support their existence. However, everybody agrees that white holes exist only for a short time. The process of emergence and collapse of a white hole is spontaneous and looks like the big band, that is why it is called sometimes as a "small bang". Such theories were studied in 2012 by Retter and Heller and in 2014 by Madriz et al.

Thus, further research will give us more information about our universe.
