The new black hole has more than 200 times the mass of our sun – and is challenging theories of how objects form in space ...

Two colossal black holes—among the most massive ever seen—collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

The massive black hole has been dubbed GW231123. Its unusual size and behavior is challenging scientists' understanding of ...

Named GW 231123 after the date it was recorded on 23 November 2023, it's the most massive black hole collision we've seen yet ...

"Theories involving substantial formation of stars prior to or together with the black hole formation and growth are very ...

The laws of general relativity suggest that it is possible for an object to have such a density that nothing, not even light, can escape. That is a black hole. There are a few defining ...

It took less than a second for the space observatory hidden in Louisiana woods to detect a black hole that is that is ...

Discoveries keep pouring out of the James Webb Space Telescope (JWST). Researchers observed an unusual cluster, which they ...

"However, there is a singularity at the center of black holes where the laws of physics as we know them break down." At those singularities, the density of black holes goes to infinity. Physicists don ...

The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

These are rare occurrences—scientists estimate that the giant black hole at the center of our Milky Way galaxy gobbles a star ...

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...
