New research suggests that the very structure of space-time may be an emergent phenomenon, arising from the entanglement of quantum information. This challenges our fundamental understanding of gravity and the universe.
Physicists are revisiting the chaotic region near singularities within black holes, utilizing new mathematical tools to potentially reconcile general relativity and quantum mechanics and gain a deeper understanding of space and time.
This article presents a white paper summarizing current knowledge on quantum gravity phenomenology and its multi-messenger signals. It provides an overview of the field, discusses experimental and observational signatures, and identifies key questions and challenges.
