Have absolute gravitational singularities ever formed?

Click For Summary
SUMMARY

The discussion centers on the hypothesis that dark energy may prevent total gravitational collapse in black holes and could have played a role in avoiding a singularity at the Big Bang. Participants speculate on the implications of a unified theory that could simultaneously eliminate classical singularities while providing an explanation for dark energy. The conversation highlights the tension between established gravitational theories and emerging concepts in cosmology.

PREREQUISITES
  • Understanding of general relativity and its implications for black hole physics.
  • Familiarity with dark energy and its role in the universe's expansion.
  • Knowledge of singularity concepts in cosmology and theoretical physics.
  • Awareness of unified theories in physics, such as string theory.
NEXT STEPS
  • Research the role of dark energy in cosmic evolution and its effects on black holes.
  • Explore the implications of general relativity on singularity formation.
  • Study unified theories, particularly string theory, and their approach to singularities.
  • Investigate current theories and models that address the Big Bang and singularity avoidance.
USEFUL FOR

Astronomers, theoretical physicists, and cosmologists interested in the interplay between dark energy, black holes, and singularity theories.

What of the possibility that dark energy prevents total gravitational collapse of black holes, and might also have helped avoid an actual singularity at the big bang?

You wouldn't expect dark energy to do that, because there is so little of it around. On the other hand, you might speculate that a unified theory will simultaneously prohibit classic singularities and explain dark energy.
