Scientists Are Searching for Clusters of Spacetime-Eating Bubbles In the Cosmos
These hypothetical bubbles could help explain the birth, and ultimate fate, of the universe.
Time Travel Without Mind-Bending Paradoxes Is Possible, Mathematical Modeling Suggests
“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.
Lasers Made of 'Spacetime Wave Packets' Are Breaking the Normal Rules of Light
“Turns out, pretty much everything we know in optics is out of the window.”
A Star Is Orbiting our Galaxy's Black Hole in a Stunning Pattern
In yet another win for Albert Einstein’s theories, scientists report the first ever detection of “Schwarzschild precession” around a black hole.
Physicists Are Studying Mysterious ‘Bubbles of Nothing’ That Eat Spacetime
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.
Spacetime 'Echoes' From Quantum Black Holes Could Soon Change Physics Forever
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.
Scientists Witnessed a Dead Star ‘Dragging’ 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.
Nobel Prize in Physics Recognizes the Dawn of a Whole New Kind of Astronomy
Rainer Weiss, Kip Thorne, and Barry Barish are named for leading the effort to detect gravitational waves.
These Black Holes Merged Nearly Two Billion Years Ago and We Have the Receipts
The newest gravitational wave discovery is the first to involve three detectors.
LIGO's Four Gravitational Wave Detections Come From Off-Kilter Black Hole Mergers
“You don’t write a paper saying: This is awesome! But we kind of have that feeling. It’s definitely a frontier.”
One of the Greatest Cosmic Mysteries Was Solved By David Shoemaker’s Device
LIGO's detection of gravitational waves was an achievement comparable to Galileo’s telescope. Meet the man whose team built the detector.
A New Search Technique Could Exponentially Boost Discoveries of Black Holes
"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."
