Entropy scale factor could solve event horizon paradoxes

The entropy scale factor (ESF) builds on work in emergent gravity to propose that gravity is due to entropy instead of the energy and momentum of general relativity. This theory proposes changes to the scale of space and time, which result in finite time dilation on the surface of black holes, contrasting with the infinite time dilation predicted by general relativity. The amount of time dilation on a Schwarzschild black hole's surface is inversely proportional to its radius, just like the Hawking temperature. Since time dilation is not infinite at the event horizon, black holes can absorb light and matter from the perspective of a non-accelerating observer, resolving the Cornish‐Moffat paradox. Since the event horizon can emit light directly, it can return information to the outside universe, resolving the black hole information paradox.

Abstract

The entropy scale factor (ESF) builds on work in emergent gravity to propose that gravity is due to entropy instead of the energy and momentum of general relativity. This theory proposes changes to the scale of space and time, which result in finite time dilation on the surface of black holes, contrasting with the infinite time dilation predicted by general relativity. The amount of time dilation on a Schwarzschild black hole's surface is inversely proportional to its radius, just like the Hawking temperature. Since time dilation is not infinite at the event horizon, black holes can absorb light and matter from the perspective of a non-accelerating observer, resolving the Cornish‐Moffat paradox. Since the event horizon can emit light directly, it can return information to the outside universe, resolving the black hole information paradox.
