This is a fun one to try and wrap your brain around:
If black holes and the Big Bang befuddle you, try wrapping your brain around this one: The entire universe may have been created in an explosion inside a black hole.
“It’s a mathematically plausible model which refines the standard model of the Big Bang,” said Blake Temple, a mathematician at the University of California, Davis.
The standard model holds that the universe began about 13.7 billion years ago. The Big Bang is described not as an explosion so much as a rapid outflow of material from a point of nearly infinite density. It is a theory, one among several attempting to describe the observed expansion of the universe today. It has not been proved.
The Big Bang has been compared to black holes before, because the tremendous crush of matter that defines a black hole is much like the unfathomable density that preceded the Big Bang. Both phenomena are termed singularities.
In the proposed modification to the standard model, the Big Bang is an actual explosion, Temple explained today in a statement, and it occurs within a black hole in an existing space. The shock wave of the explosion is expanding into an infinite space.
Temple also describes the whole scenario as a white hole, the theoretical opposite of a black hole because it tosses matter outward instead of pulling it in.
This theory is a long way from being proven, but it provides for some interesting possibilities. It’ll be fun seeing where they go with it.
