What would happen if you were able to travel closer and closer to a black hole?
If you flew a space ship close to a black hole, you could remain safely in orbit around the black hole so long as you flew outside of the event horizon. However, if you went too close and passed inside the event horizon, there would be no escape!
Can we see black holes?
Black holes have gravitational fields so strong that even light cannot escape, so they are defined by the shell of a black, featureless sphere called an event horizon. But the holes can nevertheless be seen. As they consume matter that strays too close, they squeeze it into a superheated disk of glowing gas.
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) |
|---|---|
| Mass | 1.3×1041 kg |
| Schwarzschild radius | 1.9×1014 m (~1300 AU) |
| Schwarzschild density or | 0.0045 kg/m3 |
Will the universe be filled with black holes?
After 1040 years, black holes will dominate the universe. They will slowly evaporate via Hawking radiation. A black hole with a mass of around 1 M ☉ will vanish in around 2×1066 years. As the lifetime of a black hole is proportional to the cube of its mass, more massive black holes take longer to decay.
What would we see if we fell into a black hole?
If you fell into a large enough black hole, your last moments would be a little bit like being on the inside of a distorted, one-way mirror. No one outside would be able to see you, but you’d have a view of them. Meanwhile, the gravitational pull would bend the light weirdly and distort your last moments of vision.
What would happen if you fell into a white hole?
Objects inside a white hole can leave and interact with the outside world, but since nothing can get in, the interior is cut off cut off from the universe’s past: No outside event will ever affect the inside.
Is there a limit to how far we can observe the universe?
Even though it’s been billions of years since the Big Bang, there’s a cosmic limit to how far we can observe the objects that occupy our Universe. The Universe has been expanding all this time, but that expansion rate is both finite and well-measured.
Is the universe infinitely large?
No one knows if the universe is infinitely large, or even if ours is the only universe that exists. And other parts of the universe, very far away, might be quite different from the universe closer to home. Future NASA missions will continue to search for clues to the ultimate size and scale of our cosmic home.
How big is the biggest black hole in the universe?
At the center of this beast is a supermassive black hole — the largest ever seen — with an estimated mass of 20 billion suns.
Did the universe expand into space after the Big Bang?
The universe did not expand into space, as space did not exist before the universe, according to NASA Instead, it is better to think of the Big Bang as the simultaneous appearance of space everywhere in the universe.
