What Scientists Have Learned from Hidden Ripples in Spacetime
MIT astrophysicist Nergis Mavalvala talks about the discovery of gravitational waves—and everything that has followed—on Motherboard’s “Space Show.”
Scientists Confirm Stephen Hawking’s 50-Year-Old Theory About Black Holes
A wave signal from space validates Hawking’s prediction that the area of an event horizon should never decrease.
Scientists Detect a Black Hole Eating a Neutron Star In Mind-Blowing First
Nobody had ever seen a system containing a neutron star and a black hole. In January 2020, scientists detected two of them.
'Dark Sirens' In Space Can Solve a Huge Mystery In Spacetime, Scientists Propose
Ripples in spacetime caused by black holes colliding in darkness could help scientists clock the expansion of the universe.
Scientists May Have Detected a Huge Collision Between Blobs of Dark Matter
If confirmed, the collision between never-before-seen boson stars may solve the long search for the source of dark matter.
Scientists May Have Detected a Signal That Could Change Astronomy Forever
Scientists think they may have spied the universe's "gravitational wave background" after more than a decade of searching.
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?
Scientists Detected a New Kind of Black Hole Being Born in a Bizarre Event
A merger with a black hole possessing an unexplained 'forbidden mass' created the first conclusive example of an intermediate black hole in the most massive merger ever detected using ripples in spacetime.
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.
We Actually Live Inside a Huge Bubble in Space, Physicist Proposes
What if the Earth, the galaxy, and all the galaxies near us were enclosed in a weirdly empty bubble? This scenario could resolve some longstanding questions about the nature of the universe.
Scientists Detect Waves in Spacetime From Biggest Known Neutron Star Collision
“Neutron star binaries this massive may not be detectable by current telescope surveys.”
