Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if ...

When two massive black holes slammed into each other earlier this year, astronomers were able to observe it in the clearest ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...

The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions ...

New observations of two black holes merging have confirmed predictions made decades ago by Albert Einstein, Stephen Hawking, ...

This video explores Einstein’s theory of general relativity and how gravity, as the warping of spacetime, shapes everything from planetary orbits to the bending of light. It traces the historic 1919 ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

Black hole merger detected by LIGO offers the strongest proof yet of Einstein’s relativity and Hawking’s predictions. The findings confirm black holes are defined by spin and mass. Their event ...

A Hiroshima University team has designed a feasible way to detect the Unruh effect, where acceleration turns quantum vacuum ...

Most cosmologists believe that these stars were the first large, free-floating structures to illuminate our universe, and ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect -- a long-predicted phenomenon at ...
