Most gravitational-wave models throw away uncertainty, which could make Einstein’s theory look wrong when it isn’t. Today’s authors show when this could happen and how to take care of the problem.
A new solution to Einstein’s general relativity suggests wormholes could be real and traveling through them might be possible.
Subtle whispers in gravitational waves put general relativity to the test.
In today’s bite, we investigate a controversial paper from two years ago, tracing its origins and attempting to finally answer the question: are black holes dark energy?
Today’s undergraduate research post features the work of Vrunda Macwan on black holes!
What’s better than a single gravitational lens? A double gravitational lens! Learn about how light from a distant quasar zig-zags across the universe because of the first double gravitational lens to be observed!
