How big would a black hole be with the mass of the universe?
The observable universe’s mass has a Schwarzschild radius of approximately 13.7 billion light-years….Parameters.
| Object | TON 618 (largest known black hole) |

| Schwarzschild density or | 0.0045 kg/m3 |
How big would a black hole be with the mass of the moon?
0.2 millimeters
A body with the mass of our moon (about 7 million trillion tons!) would be compressed into a black hole with a diameter of only 0.2 millimeters!
Can a black hole be the size of a galaxy?
Galaxy Size Step aside, supermassive black holes — scientists say that there could be black holes the size of an entire galaxy. “The supermassive black holes go up to nearly 100 billion solar masses,” Queen Mary University of London astronomer Bernard Carr, who worked on the new research, told Futurism.
Can a black hole have a moon?
Dark Matter Evidence The paper’s authors believe that evidence of these miniature black holes could shed light on dark matter, the elusive stuff that many physicists believe accounts for the majority of matter in the universe.
What if a small black hole replaced the sun?
If the Sun were replaced by an equally massive black hole, all the planets would remain in their present orbits, circling the black hole at a safe distance. Life would be impossible without the light and heat from the Sun, but at least Earth would survive.
How big is the biggest black hole in the universe?
It’s 24 billion miles across and contains the same mass as 6 1/2 billion suns. But this supermassive black hole, as large as it is, could still fit within our solar system with plenty of room to spare. So we have to look at one of the most massive of all supermassive black holes. It has a diameter of about 78 billion miles.
Do black holes grow beyond their limit?
But these gigantic black holes, which accumulate mass by sucking in matter from neighboring gas, dust and stars, seem unable to grow beyond this limit regardless of where – and when – they appear in the universe. “It’s not just happening today,†said Natarajan. “They shut off at every epoch in the universe.â€
What happens when matter falls into a black hole?
These motions imply a dark, massive body whose mass can be computed from the speeds of the stars. The matter that falls into a black hole adds to the mass of the black hole. Its gravity doesn’t disappear from the universe. This animation illustrates the activity surrounding a black hole.
How long does it take for a black hole to form?
It can take less than a billion years for one to reach a very large size, but it is unknown how long it takes them to form, generally. Scientists obtained the first image of a black hole, seen here, using Event Horizon Telescope observations of the center of the galaxy M87.
