Let's say that I pose a mirror-universe that started off as the mirror image (wrt momenta of particles) of ours. Like a pair of universes. Of course there could be any number of different universes besides that. But my point is our universe (pair). I suspect that the creation of two particles that have opposite momentum can be created with zero energy, but I'm not sure.jim mcnamara said:@entropy1 I'm confused - are you saying there must be more Universes, not just one? Or are you asking could there be two or more?
Why in the world would you suspect that? Do you see oppositely charging elephants popping up all around you?entropy1 said:I suspect that the creation of two particles that have opposite momentum can be created with zero energy, but I'm not sure.
Ok. That was very dumb of me I suppose...Bandersnatch said:Why in the world would you suspect that? Do you see oppositely charging elephants popping up all around you?
The energy has to come from somewhere, although your idea is correct, virtual particles appear as oppositely charged pairs in our current universe. If a virtual particle big bang is your belief then an equal antimatter universe is pretty much a given.entropy1 said:Ok. That was very dumb of me I suppose...

The most accepted theory is the Big Bang, which suggests that the universe began as a singularity with infinite density and zero energy. This singularity then expanded rapidly and created all matter and energy in the universe.
Energy played a crucial role in the creation of the universe. As the singularity expanded, it released a tremendous amount of energy, which eventually cooled down and formed matter. This matter then clumped together to form stars, galaxies, and eventually, planets.
Yes, there is a significant amount of evidence that supports the Big Bang theory. One of the most convincing pieces of evidence is the cosmic microwave background radiation, which is the leftover heat from the initial expansion of the universe. Additionally, the abundance of light elements, such as hydrogen and helium, also supports this theory.
Currently, we do not have the technology or understanding to create a universe from zero energy in a lab. The conditions required for the Big Bang to occur are beyond our current capabilities. However, scientists continue to research and explore this concept through experiments and simulations.
Some alternative theories include the Steady State theory, which suggests that the universe has always existed and is continuously expanding, and the Oscillating Universe theory, which proposes that the universe goes through cycles of expansion and contraction. However, the Big Bang theory remains the most widely accepted explanation for the creation of the universe from zero energy.
