A universe with many black holes has several baby universes
This theory arose from the theory that we are a child of a black hole. The idea is that when matter is pulled into a black hole, it becomes so dense that the black hole spits it out and forms a universe from it. Remember white holes?
We create a universe every time we make a decision
This theory takes a different approach to the theory of the omniverse, or having many worlds. It states that we give birth to a new universe every time we make a decision since that is how we create reality.
Our universe is constantly smashing into a neighboring universe
According to the Clashing Branes Theory, our universe is a membrane floating in higher dimensional space and constantly smashing into a neighboring universe. This theory leads to the idea that a new big bang is produced every now and then which in turn leads to even more universes.
Space-time is a super-fluid substance
The theory that space-time flows with zero friction is considered to be one of the most bizarre theories of this century. According to physicists Pawel Mazur and George Chapline, if space-time is super-fluid that means that the rotation of the universe causes super-fluid space-time to scatter with vortices. Those vortices give birth to galaxies, causing the never-ending expansion of the universe.
Universes continue to evolve, and those with the most black holes dominate the multiverse
A scientist once theorized that when matter is compressed to extreme densities at the center of a black hole, it leads to the creation of a baby universe. These universes evolve, make many black holes, and dominate the multiverse.
