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. CONTENTS.
21 paź 2020 · It is expected that when quantum gravity is better understood that BHs, WHs and wormholes might play an important role in our understanding of spacetime and perhaps even in understanding the origin of the Big Bang.
White holes and FRBs. arXiv:1811.03368. T-reflection of a black hole. „is not always white“: like the black hole having active and passive phases, main collapse event and episodic matter injections, its T-reflection should not be always active, can eject the matter episodically.
11 lip 2023 · Why white holes may not exist. While general relativity describes white holes in theory, no one knows how one might actually form. A black hole cordons off its bit of space when a star...

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.
