Configurations like these, known as Einstein crosses, typically consist of four distinct points of light. This particular ...

The merger of two black holes is a momentous event, revealing the wildest and most extreme configurations of space, time and gravity known to science.Researchers have now gotten their best look yet at ...

Space and time seem like two completely different ideas, but Einstein showed they are interlinked in what is known as ...

To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could just physics smarter and build one on a lab ...

Gravitational waves shake the very fabric of the universe when black holes collide. Today we measure these events and use them to understand the cosmos. Now University of Copenhagen researchers and ...

For the first time, scientists measured a newborn black hole that "kicked" off into space after 2 larger black holes merged together.

Science is a story of coming up with theories then doing our best to disprove them. That is especially true for theories on a ...

Is time something that flows — or just an illusion? Exploring space-time as either a fixed “block universe” or a dynamic fabric reveals deeper mysteries about existence, change, and the very nature of ...

Since that day, LIGO — composed of two highly sensitive laser interferometers located in Hanford, Washington and Livingston, ...

A decade ago, scientists first detected ripples in the fabric of space-time, called gravitational waves, from the collision ...

A decade after the first discovery, scientists have used these waves to find a unique merger, a massive binary system and a ...
