These hypothetical bubbles could help explain the birth, and ultimate fate, of the universe.
“Agents could have free choice to make any action they wanted and no paradox would arise because the events just adjust themselves to remain consistent," said study author Germain Tobar.
“Turns out, pretty much everything we know in optics is out of the window.”
In yet another win for Albert Einstein’s theories, scientists report the first ever detection of “Schwarzschild precession” around a black hole.
A spontaneous hole in the fabric of reality could theoretically end the universe, but don't worry: physicists are studying the idea for what it can teach us about the cosmos.
Scientists are racing to confirm the detection of black hole "echoes" that could unlock exotic new branches of physics and deepen our understanding of the fabric of reality.
Astronomers spent 20 years using a dead star as a gigantic "cosmic clock" to test a mind-blowing prediction of Einstein's general theory of relativity.
Rainer Weiss, Kip Thorne, and Barry Barish are named for leading the effort to detect gravitational waves.
The newest gravitational wave discovery is the first to involve three detectors.
“You don’t write a paper saying: This is awesome! But we kind of have that feeling. It’s definitely a frontier.”
LIGO's detection of gravitational waves was an achievement comparable to Galileo’s telescope. Meet the man whose team built the detector.
"For the past 10,000 years, astronomers have been studying the light side of the universe. We have now just begun to study the dark side of the universe."
