What is a quantum fluctuation and how do they form a seed for black holes?:
Loren said:Quantum fluctuations are simply a variation in the vacuum energy of a point in space.
As far as I know, black holes are formed by the accumulation of mass. Once a critical amount is acquired within a specific region of space the mass collapses to form a black hole.
There are theories about the possibility of micro-black holes, but no one has observed/detected any and it is simply a theory.
wolram said:I thought it was big bang, plasma, quantum fluctuation, black hole, or some form of creation from a QF.
PeterDonis said:Can you give a reference that describes a specific model of primordial black hole creation from quantum fluctuations?
wolram said:I have found this article that states that matter is all quantum fluctuations.
wolram said:Under these conditions, simple fluctuations in the density of matter may have resulted in local regions dense enough to create black holes.
A quantum fluctuation is a temporary and spontaneous change in the energy of a subatomic particle or system. It is a fundamental aspect of quantum mechanics, which describes the behavior of particles at a microscopic level.
Quantum fluctuations occur due to the inherent uncertainty in the behavior of subatomic particles. According to Heisenberg's uncertainty principle, it is impossible to know both the position and momentum of a particle with absolute certainty. This allows for temporary changes in the energy of a particle, known as quantum fluctuations.
No, quantum fluctuations can also occur in empty space, known as vacuum fluctuations. In empty space, particles and antiparticles constantly pop in and out of existence, creating temporary quantum fluctuations in the energy of the vacuum.
Quantum fluctuations are not directly observable, but their effects can be seen through experiments and calculations. For example, the Casimir effect is a phenomenon that can be explained by vacuum fluctuations.
At this time, quantum fluctuations cannot be controlled or harnessed for practical use. However, scientists are studying ways to manipulate and exploit these fluctuations in the future for potential applications in quantum computing and other technologies.
