Runaway black hole mergers may have built supermassive black holes
The researchers used cosmological simulations to recreate the first 700 million years of cosmic history, focusing on the formation of […]
New black hole merger bolsters Hawking area theorem
Skip to content a black hole hunting machine Physicists spliced merger’s gravitational signal into isolated frequencies to determine surface areas. […]
There could be “dark main sequence” stars at the galactic center
Dark matter particle and antiparticle collisions could make some stars immortal. For a star, its initial mass is everything. It […]
Merger of two massive black holes is one for the record books
Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two […]
New evidence that some supernovae may be a “double detonation”
Skip to content It may be possible to blow up a white dwarf before it reaches a critical mass. Type […]
Simulations find ghostly whirls of dark matter trailing galaxy arms
“Basically what you do is you set up a bunch of particles that represent things like stars, gas, and dark […]
Milky Way galaxy might not collide with Andromeda after all
100,000 computer simulations reveal Milky Way’s fate—and it might not be what we thought. It’s been textbook knowledge for over […]
Testing a robot that could drill into Europa and Enceladus
We don’t currently have a mission to put it on, but NASA is making sure it’s ready. Geysers on Saturn’s […]
New data confirms: There really is a planet squeezed in between two stars
And, critically, the entire orbit is within the orbit of the smaller companion star. The gravitational forces of a tight […]
