An orbital experiment is about to test to see if objects really fall at same speed in a gravitational field -- or wither some exotic physics may be detected.
Can a 74-year-old theoretical physicist to remain playful? When thinking of Stephen Hawking, it's certainly possible.
Mankind’s biggest ever platform for scientific discovery goes offline when Mother Nature intervenes.
Hawking said it's not likely that scientists will find intelligent alien life in the next 20 years. But he had one caveat.
In tonight's special Perimeter Institute public lecture, Nobel Laureate Art McDonald will delve into the science behind detecting the most ghostly known particles in the universe. Watch it here, live, at 7pm EDT!
The United States signed a new partner to expand the search for gravitational waves, ripples in the interwoven fabric of space and time set off by the motions of massive objects, like merging black holes.
Now the elusive ripples in spacetime have been found, scientists are planning for a rich future for using gravitational wave observatories to unmask the warped side of cosmos.
Black hole theoretical physicist Stephen Hawking has some thoughts on the discovery of gravitational waves.
