The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
Two independent papers vanquish lingering doubts about LIGO’s historic discovery of gravitational waves.
Quasars powered by supermassive black holes have been unexpectedly vanishing. Scientists have started to figure out why.
Hot spots have been discovered orbiting just outside the supermassive black hole at the galaxy’s center. Their motions have given us the closest look at that violent environment.
Black holes occasionally reveal themselves when passing stars get ripped apart by their gravity. These tidal disruption events have created a new way for astronomers to map the hidden cosmos.
