Two massive black holes smashed together and completely changed what we know about the universe. This physics-altering collision simply doesn't make sense.
This artist’s concept illustrates a supermassive black hole with millions to billions times the mass of our sun. Supermassive black holes are enormously dense objects buried at the hearts of galaxies. Image credit: NASA/JPL-Caltech At the core, millions of tonnes of hydrogen are being converted...
Thus a black hole formed in a binary system will end up being larger than a black hole born solo. As the black holes age, they continue to feed on any surrounding gas, which the astronomers also estimated. Lastly, occasionally black holes find each other in the darkness of interstellar ...
The former, as the name suggests, are formed when a star of sufficiently large mass (i.e., at least twenty times more massive than our sun) exhausts its fuel and succumbs to the force of gravity by collapsing in on itself: they represent the lightest type ofblack hole, and we have ...
Astronomers have observed objects called quasars, which glow brighter than thousands of galaxies put together and are thought to be powered by supermassive black holes consuming matter. Quasars have been seen back as far as the first billion years after the Big Bang, when our universe formed, ...
and from that we can learn all sorts of things from how black holes are formed through to the creation of the universe itself. These radio waves require a very large telescope, which is why the VLA is actually made up of 27 dishes, which work together to capture radio waves. There’s ...

Black holes are regions of space wheregravityis so strong that not even light can escape and so isolated black holes are truly dark objects and don't emit any form of radiation. However, black holes that get deformed, because of other black holes or stars crashing into them, are known to...
