A Solution to the “Final Parsec Problem?”
Supermassive Black Holes are Nature's confounding behemoths. It's difficult for Earth-bound minds to comprehend their magnitude and power. Astrophysicists have…
Primordial Black Holes Can Only Explain a Fraction of Dark Matter
What is Dark Matter? That question is prominent in discussions about the nature of the Universe. There are many proposed…
Merging Black Holes Could Give Astronomers a Way to Detect Hawking Radiation
Nothing lasts forever, including black holes. Over immensely long periods of time, they evaporate, as will other large objects in…
Here’s Why We Should Put a Gravitational Wave Observatory on the Moon
Scientists detected the first long-predicted gravitational wave in 2015, and since then, researchers have been hungering for better detectors. But…
Black Holes Need Refreshing Cold Gas to Keep Growing
How were supermassive black holes able to grow so rapidly in the early Universe? Galactic mergers were believed to be…
Next Generation Gravitational Wave Observatories Could Detect 100-600 Solar Mass Black Hole Mergers
Humans are born wonderers. We're always wondering about the next valley over, the next horizon, what we'll understand next about…
Ultra-Massive Black Holes: How Does the Universe Produce Objects So Massive?
Black holes are the most massive objects that we know of in the Universe. Not stellar mass black holes, not…
When Black Holes Collide They Also Produce Neutrinos
Ever since astronomers first detected ultra high energy neutrinos coming from random directions in space, they have not been able…
Shortly Before They Collided, two Black Holes Tangled Spacetime up Into Knots
An international team led from Cardiff University has confirmed that black hole binaries experience precession.
Astronomers Discover two Supermassive Black Holes Orbiting Each Other, Doomed to Collide in the Future.
Until recently, one of the closest orbiting each other pairs of supermassive blackholes was found in NGC 7727. That pair…
