The secret is in their ability to withstand heat.
Normal matter makes up just five percent of the universe, but we can only see about 2.5 percent of it.
Rainer Weiss, Barry C. Barish and Kip S. Thorne win for "decisive contributions to the LIGO detector and the observation of gravitational waves."
How supermassive black holes formed so quickly after the start of the universe has long baffled scientists.
Studying neutrinos will help researchers answer fundamental questions about the universe.
The last of his tweets leaves science aside for what could read as a political statement.
Object found hiding in a cloud of molecular gas believed to be an elusive type of black hole.
Physicists discuss the latest discovery of 15 radio bursts coming from a galaxy three billion light years away.
Astronomers discover hypervelocity stars originally came from a dwarf galaxy orbiting the Milky Way.
Scientists' observations could help us understand what could happen to our own galaxy in the future.
Hawking said we need to leave within 500 years “if humanity is to continue for another million years.”
“From your native country one cannot expect—in the foreseeable time—a more reasonable political attitude,” he wrote of the U.S.
Einstein predicted that gravity and light could be used to calculate the mass of a star. But he never thought scientists could actually do it.
The ripples in space-time were first predicted by Einstein more than 100 years ago.
Scientists have long tried to explain the origin of a mysterious, large and anomalously cold region of the sky—and a new study opens up a pretty wild possibility.
Since HG Wells imagined humans traveling in time with technology, literature has inspired science. Will time travel be possible one day?
The theory breaks with the popular idea that expansion is caused by dark energy and suggests energy for expansion would never run out.
Earth's magnetic field has reversed periodically throughout the planet's history. Now, we're a little closer to understanding why.
Thirty-three scientists refuted the suggestion the universe began with a big "bounce" rather than a big bang.
“People think of time travel as something fictional. But, mathematically, it is possible.”
Physicists say proton collisions can result in a large number of particles containing strange quarks—findings that challenge current theoretical models.
Thanks to an enormous telescope network, scientists are now pushing the frontiers of what we know about the universe.
