A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information. more
A basic question in black hole horizon physics the leading breakdown of the low-energy description in terms of quantum fields and general relativity (collectively known as effective field theory).  Although black hole horizons are weakly curved, because of long time-evolution large energies build... more
