Scientists propose detecting spacetime foam, a quantum fluctuation effect, by observing quasar halos. The Very Large Telescope interferometer may soon probe spacetime fabric and infer dark energy or matter. This research offers new cosmological insights.

Area of Science:

  • Quantum physics
  • Cosmology
  • Astrophysics

Background:

  • Quantum fluctuations suggest spacetime may possess a

Purpose of the Study:

  • To propose a method for detecting the texture of spacetime foam.
  • To investigate the potential of the Very Large Telescope interferometer in probing spacetime.
  • To explore the use of spacetime foam physics and computation for inferring dark energy or matter.

Main Methods:

  • Observing halo structures in images of distant quasars.
  • Utilizing the Very Large Telescope interferometer's capabilities.
  • Applying principles of spacetime foam physics and computation.

Main Results:

  • The Very Large Telescope interferometer, at its design performance, will be capable of probing the fabric of spacetime.
