Gravitational Collapse in Gravity's Rainbow

TL;DR

This paper explores how gravity's rainbow modifies black hole horizons, allowing particles of different energies to perceive different horizons, which could enable information escape from black holes.

Contribution

It demonstrates that in gravity's rainbow, the horizon position depends on particle energy, potentially allowing information to escape black holes.

Findings

Horizon position varies with particle energy.

Particles inside and outside perceive different horizons.

Information can escape black holes in gravity's rainbow.

Abstract

In this paper, we will analyze the gravitational collapse in the framework of gravity's rainbow. We will demonstrate that the position of the horizon for a particle inside the black hole depends on the energy of that particle. It will also be observe that the position of the horizon for a particle falling radially into the black hole also depends on its energy. Thus, it is possible for a particle coming from outside to interact with a particle inside the black, and take some information outside the black hole. This is because for both these particles the position of horizon is different. So, even though the particle from inside the black hole is in its own horizon, it is not in the horizon of the particle coming from outside. Thus, we will demonstrate that in gravity's rainbow information can get out of a black hole.
