Steven Hawking held a time travel party in 2009 for future humans, but no visitors have arrived, leaving the event as a curious experiment in physics history.

Ten years after the first detection of gravitational waves, scientists have captured the clearest signal yet — and it confirms one of Stephen Hawking’s most famous predictions. Using the upgraded LIGO ...

On Sept. 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger of two black holes. Now, in the ...

Studying black holes is immensely difficult, but with gravitational wave detection, astrophysicists do have a way to directly analyze these mysterious objects. A new study details the “clearest ...

A new program at the University of Cambridge library in the UK is asking people to bring in their floppy disks so that any digital artifacts on them can be extracted. Among rediscovered files are ...
