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.”
“If it turns out to be right, then we’ve confirmed a new type of star system. It’s that fundamental.”
“When these objects merge, there is more energy produced than the rest of the universe put together.”
A statistical analysis of 740 supernovas found that black holes can only account for 40 percent of dark matter in the universe, putting another nail in the coffin for the MACHOs theory of dark matter.
The supermassive black hole at the galactic core seems to have an abundance of smaller black hole friends.
Interference is playing havoc with radio telescopes.
Astronomers capture both a gravitational wave and optical imagery from the energetic union of two neutron stars in a distant galaxy.
Rainer Weiss, Kip Thorne, and Barry Barish are named for leading the effort to detect gravitational waves.
