A theory by Albert Einstein has helped astronomers discover a rare exoplanet, sparking new ideas of where they can be found.

According to a new study, the universe may decay many orders of magnitude faster than we thought. The study, which looked at the Hawking radiation of stellar remnants, predicts that the universe ...

Importantly, the theory allows gravity to be represented in flat space-time using the Minkowski metric, without requiring the curved space-time of general relativity.

The method involves simulating curved space-time with a branched electrical circuit, where the electrical signals at each branch point correspond to the gravitational dynamics that would be ...

Illustration of the theory used to model quantum gravity: The lattice simulates a curved space-time—near the boundary, the lattice is denser due to the curvature.
