Can a black hole form a galaxy?
When scientists measured the masses of several enormous black holes and those of their host galaxies’ bulges, they found a proportional relationship between the two. This means that the formation of a massive black hole and its galaxy are very closely related to each other.
How do black holes impact galaxies?
Virtually all massive galaxies, including our own, host central black holes ranging in mass from millions to billions of solar masses. The growth of these black holes releases vast amounts of energy that powers quasars and other weaker active galactic nuclei.
What would happen if a black hole entered our galaxy?
As the black hole made its way through the Solar System, it would disrupt the orbits of all the planets in it. Likely, our space intruder would tangle the biggest planet in the system, Jupiter. The black hole would pull all the gas from the giant planet, turning it into a swirling hot disk.
How do galaxy black holes form?
Stellar black holes result from the collapse of massive stars, and some have suggested that supermassive black holes form out of the collapse of massive clouds of gas during the early stages of the formation of the galaxy.
How does a galaxy form?
Galaxies are collections of stars, gas, dust and dark matter held together by gravity. Galaxies are thought to begin as small clouds of stars and dust swirling through space. As other clouds get close, gravity sends these objects careening into one another and knits them into larger spinning packs.
What makes a galaxy cluster explode?
The eruption is generated by a black hole located in the cluster’s central galaxy, which has blasted out jets and carved a large cavity in the surrounding hot gas. Researchers estimate this explosion released five times more energy than the previous record holder and hundreds of thousands of times more than a typical galaxy cluster.
How do black holes explode?
This happens when matter falling toward the black hole is redirected into jets, or beams, that blast outward into space and slam into any surrounding material. Chandra observations reported in 2016 first revealed hints of the giant explosion in the Ophiuchus galaxy cluster.
What happens when a neutron star and black hole collide?
A neutron star can also merge with a black hole to make a bigger black hole, or two black holes can collide. Mergers like these also make black holes quickly, and produce ripples in space-time called gravitational waves.
What is the relationship between black holes and galaxies?
On a larger scale, most galaxies seem to have supermassive black holes at their centers. The connection between the formation of these supermassive black holes and the formation of galaxies is still not understood. It is possible that a black hole could have played a role in the formation of our Milky Way galaxy.
