Beyond Einstein: Gravitational Rainbows. Much as a gentle mist can split light waves into beautiful rainbows, dark energy may split gravitational waves into deeply revealing gravitational rainbows. Leading researcher Claudia …

Albert Einstein spent his last thirty years unsuccessfully searching for a ‘unified theory’ — a single master principle to describe everything in the universe, from tiny subatomic particles to immense clusters of galaxies. In the decades since, generations of researchers have continued working toward Einstein’s dream.

The first detection of colliding black holes rocked the scientific world, establishing that gravitational waves are real and that we are able to measure them. More recently, scientists have achieved …

As physicists attempt to answer some of science’s biggest questions about the universe, they are testing the limits of experimental and observational science itself. In this program leading physicists, astronomers, …
