On the physical implications of Hawking's spacetime foam
arXiv:1810.09574 · doi:10.1002/prop.201800070
Abstract
Hawking's spacetime foam model predicts that due to quantum fluctuations, spacetime is filled with black hole like objects. We argue that Hawking's model implies a cosmological constant of the observed order and that it can also be used to solve the problem of time in quantum gravity.
