- Title
Quantum gravity: An astrophysical constraint.
- Authors
Carroll, Sean
- Abstract
A quantum theory of gravity is proving elusive. Observations of radiation from the Crab nebula now place even stronger constraints on the likelihood of detecting the effects of quantum gravity. The effects of quantum gravity might cause small violations of space time symmetries, violations that could be directly observed through the behavior of particles at high energies or over large distances.
