Physicists Create Black Hole Analog in Lab, Observing Simulated Hawking Radiation

Simulated Hawking radiation may only be thermal under specific conditions related to spacetime warp.

In November 2022, a team led by Lotte Mertens at the University of Amsterdam used a one-dimensional chain of atoms to simulate a black hole's event horizon, observing Hawking radiation-like effects, which may help reconcile general relativity and quantum mechanics.

  • Black hole analogs simulate Hawking radiation effects.
  • 2022 study used a chain of atoms.
  • Event horizon prevents escape from black holes.
  • Stephen Hawking proposed radiation in 1974.
  • Simulated radiation matched theoretical black hole predictions.
  • Research published in Physical Review Research.

A team of physicists simulated a black hole in a laboratory setting in 2022, creating an event horizon using a chain of atoms. This experiment allowed them to observe the equivalent of Hawking radiation, which is theorized to be emitted by real black holes.

Understanding Black Hole Analogues

The black hole analog was created by arranging atoms in a single file. This setup enabled electrons to ‘hop’ between positions, simulating the event horizon of a black hole. By adjusting the ease of this hopping, the physicists produced a rise in temperature that aligned with theoretical predictions for a black hole system.

According to the source, this rise in temperature occurred only when part of the atomic chain extended beyond the event horizon. This finding suggests that the entanglement of particles across the event horizon is crucial for generating Hawking radiation. The simulated radiation was thermal under specific conditions, indicating that it may only manifest in certain scenarios.

Implications for Quantum Gravity

The research aims to bridge the gap between the general theory of relativity and quantum mechanics, which currently conflict in their descriptions of the Universe. The study offers a method to investigate Hawking radiation without the complexities associated with actual black hole formation. The simplicity of the model allows for its application in various experimental setups.
