MIT astrophysicist Nergis Mavalvala talks about the discovery of gravitational waves—and everything that has followed—on Motherboard’s “Space Show.”
A wave signal from space validates Hawking’s prediction that the area of an event horizon should never decrease.
Nobody had ever seen a system containing a neutron star and a black hole. In January 2020, scientists detected two of them.
Ripples in spacetime caused by black holes colliding in darkness could help scientists clock the expansion of the universe.
If confirmed, the collision between never-before-seen boson stars may solve the long search for the source of dark matter.
Scientists think they may have spied the universe's "gravitational wave background" after more than a decade of searching.
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 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.
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.
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.
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.
“Neutron star binaries this massive may not be detectable by current telescope surveys.”
