22 lis 2018 · Quantum tunneling of a black hole into a white hole provides a model for the full life cycle of a black hole. The white hole acts as a long-lived remnant, solving the black-hole...
This is a review of some recent developments on quantum gravity aspects of black hole physics. In particular, we focus on a scenario leading to the prediction of the existence of a Planck-mass quasi-stable object, that could form a component of dark matter.
In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy - matter, light and information can escape from it. In this sense, it is the reverse of a black hole, from which energy-matter, light and information cannot escape.

31 paź 2021 · gravitational attraction can be demonstrated as curvature of a two-dimensional surface [1]. Similarly, a black hole can be thought of as a severe curvature of spacetime [2]. Then, the white...

21 kwi 2023 · While there is observational evidence for the existence of compact objects that are “cold, dark, and heavy”, which thereby are natural candidates for black holes, the theoretically viable time-reversed variants — the “white holes” — have nowhere near the same level of observational support.
