What would happen if you put a rope in a black hole?
Newton said that gravity was a force. So, on a Newtonian black hole, you can escape just by exceeding the black hole’s force of gravity. If your rope is strong enough and somebody pulls you up with enough strength, then you could escape. But gravity doesn’t work the way Sir Isaac Newton thought.
Can we put something in a black hole?
By their calculations, quantum mechanics could feasibly turn the event horizon into a giant wall of fire and anything coming into contact would burn in an instant. In that sense, black holes lead nowhere because nothing could ever get inside. This, however, violates Einstein’s general theory of relativity.
Could you pull something out of a black hole?
Astronomers have found that the magnetic field strengths near supermassive black holes can be as strong as their intense gravitational fields. In fact, these magnetic fields are able to expel material from the vicinity of the black hole to form highly energetic outflows called ‘jets’.
What does not move fast enough to escape from a black hole?
The event horizon of a black hole is linked to the object’s escape velocity — the speed that one would need to exceed to escape the black hole’s gravitational pull. According to Einstein’s theory of special relativity, nothing can travel faster through space than the speed of light.
Could you lower a rope into a black hole?
Gravity is obviously too strong, so you cannot rope down into a Black Hole.
How small is the actual black hole?
The crescent shape arises from the black hole’s rotation and relativistic beaming; the shadow is about 2.6 times the diameter of the event horizon….Physical properties.
| Class | Approx. mass | Approx. radius |
|---|---|---|
| Supermassive black hole | 105–1010 M ☉ | 0.001–400 AU |
| Intermediate-mass black hole | 103 M ☉ | 103 km ≈ REarth |
Can you escape event horizon?
Since general relativity states that nothing can travel faster than the speed of light, nothing inside the event horizon can ever cross the boundary and escape beyond it, including light. Likewise, any radiation generated inside the horizon can never escape beyond it.
How strong is the gravity of a black hole?
As with all bodies, the gravity of black holes is proportional with their mass, which varies widely. A black hole could have not just 1000 times that of Sol; some have gravity billions of times stronger. The one recently imaged by the Event Horizon Telescope, the supermassive black hole in the galaxy M87, is one such.
Can there be a black hole 1000x more massive than our Sun?
Well, sure there can exist a black hole 1000x more massive than our Sun, but it isnt even essentially required to have one to get 1000x more gravitational attraction from a black hole to some custom object; compared with attraction Sun exerts to selected object..
How is a black hole formed?
Black holes are formed in many ways, but the most common is as the remnant of a iron-core-collapse supernova, where the star’s metallicity is fairly low but the mass of the star is medium to high (>25 solar masses).
