Without knowing whether WIMPs or axions or something else are what dark matter is composed of, can we speculate about the vacuum density creating only normal matter, and by what mechanism?
What do you mean vacuum "density" creates matter of any kind? I don't understand what you are asking.Dr Aaron said:Without knowing whether WIMPs or axions or something else are what dark matter is composed of, can we speculate about the vacuum density creating only normal matter, and by what mechanism?
The "quantum foam" that you are describing is speculation by John WheelerDr Aaron said:In a vacuum such as space, matter particles can spontaneously be generated into existence and then pop out of existence just as suddenly. The vacuum density drives this, to my understanding, as "potential" energy is transformed into matter as projected by that Einstein guy. However, we can only detect this action when the new material is normal matter. Does anyone know of any theory relating to the generation of dark matter from this vacuum density? or how normal matter sub-atomic particles are generated by this vacuum energy?
There is no such process.Dr Aaron said:In a vacuum such as space, matter particles can spontaneously be generated into existence and then pop out of existence just as suddenly.

mfb, I stand corrected.mfb said:There is no indication that our universe was without particles at any time. The end of inflation might have produced more particles, but we don't know the composition at that point in time anyway.
Vacuum density refers to the amount of energy or matter present in a vacuum. In quantum mechanics, a vacuum is not truly empty, but rather filled with fluctuating energy and particles. This energy and particles contribute to the vacuum density.
No, vacuum density alone cannot produce normal matter. Matter can only be created through physical processes such as nuclear fusion, particle collisions, or chemical reactions. Vacuum density may contribute to these processes, but it cannot directly produce matter.
Normal matter refers to the particles that make up the visible universe, such as protons, neutrons, and electrons. These particles are made up of smaller building blocks called quarks and interact through fundamental forces like gravity and electromagnetism.
Vacuum density plays a crucial role in the evolution of the universe. It is thought to be responsible for the expansion of the universe and the accelerating rate of that expansion. Vacuum density also influences the formation and behavior of particles and fields in the universe.
Yes, vacuum density can be indirectly measured through experiments and observations of the effects it has on the universe. These measurements help scientists better understand the properties of vacuum and its role in the evolution of the universe.
