Scientists Found a Raging Galactic Core From Near the Beginning of Time
The active galactic nucleus is powered by a supermassive black hole and was spotted just 670 million years after the Big Bang, making it the most distant quasar ever discovered.
Scientists Think the Multiverse Might Be the Key to Explaining Dark Matter
A new study theorizes that black holes made of collapsed universes originate dark matter, and our own universe may look like a black hole to outsiders.
Scientists Are Hunting for a Mysteriously Missing Supermassive Black Hole
A distant galaxy should have a back hole that is billions of times more massive than the Sun, but it's nowhere to be found. Where is it?
A Black Hole Is Eating a Web of Galaxies on the Edge of Spacetime
It has taken virtually the entire lifespan of the universe for the light from the 'Web of the Giant' to reach Earth.
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.
A Strange Pair of Dead Stars Might Just Solve Key Mysteries of the Universe
Where did the elements that make up our bodies come from? How fast is the universe accelerating? A pair of dead stars, among the weirdest scientists have seen, could point toward the answers.
Ripples in Spacetime Keep Revealing Bizarre Occurrences in Space
Two recent studies probed ripples in spacetime from cataclysmic black hole events to reveal light in an implausible place and a mystery object in the cosmos.
A Massive Star Has Seemingly Vanished from Space With No Explanation
Astronomers are trying to figure out whether the star collapsed into a black hole without going supernova, or if it disappeared in a cloud of dust.
Astronomers May Have Seen Colliding Black Holes Spark Up For The First Time
Usually, when black holes collide, they create gravitational waves that may be detected from Earth. But now, a flare of light has changed that.
Future Humans Can Mine Black Holes for Energy by Feeding Them, Experiment Suggests
A famed physicist dreamed decades ago that future humans, or aliens, could generate energy from black holes. Now, physicists have experimentally shown that it could one day be possible.
Is There a Black Hole Hiding in Our Solar System? This Is How We'll Find Out
Edward Witten, an influential physicist who developed M-theory, recently started thinking about how to scan the solar system for a primordial black hole.
Scientists Have Discovered the Nearest Known Black Hole to Earth
The "dark" black hole is so close to Earth that you can see the system it's in with the naked eye, and hints that there may be many more hidden black holes in the universe.
