SUMMARY

This discussion centers on the influence of quantum foam, specifically virtual particles, on the gravitational background of the universe. Participants explore the potential for quantum foam to contribute to the missing matter problem, particularly dark matter, and question whether quantum foam is uniformly distributed throughout space. The conversation emphasizes the speculative nature of these ideas, noting the necessity for peer-reviewed references to substantiate claims. Current understanding remains constrained until a comprehensive theory of Quantum Gravity is established.

PREREQUISITES
  • Understanding of quantum mechanics and virtual particles
  • Familiarity with concepts of dark matter and gravitational theories
  • Knowledge of spacetime and its properties
  • Awareness of peer-reviewed scientific literature standards
NEXT STEPS
  • Research the latest theories in Quantum Gravity
  • Examine peer-reviewed articles on the implications of quantum foam
  • Study the relationship between dark matter and quantum fluctuations
  • Explore the concept of spacetime density variations due to gravity
USEFUL FOR

Physicists, cosmologists, and researchers interested in the intersection of quantum mechanics and gravitational theory, particularly those exploring the nature of dark matter and quantum foam.

I see that this had been asked years ago, but I want to know if something new arise from this question.

Does quantum foam (virtual particles), with the sum of all these virtual particles popping into existence, may exert some gravity background?

If the sum of all this virtual particles popping into existence, can exert some gravity background, are there any way to estimate this gravity exerted in a volume?

If that's the case: How much of the matter missing (dark matter) can be explained by this quantum foam gravity?

Do we live in a universe, where this quantum foam is homogeneous distributed? Or not all the space are of the same density, for quantum foam? I guess that at least when the space is bended by gravity, the quantum foam change in density.

These are speculative areas in physics and as such we don't discuss them here at PF unless you have a peer reviewed reference that your question is based on.

Wikipedia has a writeup on the Quantum foam idea but there's no references to the latest thinking on it:

https://en.wikipedia.org/wiki/Quantum_foam

but it may help to answer some of your questions.

Until we get a theory of Quantum Gravity our understanding of spacetime at very small dimensions is limited.
