Could you orbit a black hole inside the event horizon?
Yes, stable orbits exist inside event horizons for certain classes of black hole solutions. Yes, stable orbits exist inside event horizons for certain classes of black hole solutions. It is instructive at this point to review the mechanism that prevents stable orbits in the interior Schwarzschild geometry.
Is it possible to have a stable orbit around a black hole?
In order to receive strong enough CMB light, a planet would need to orbit very close to the black hole’s event horizon. Normally an object that close would soon get sucked in. If the black hole is spinning fast, however, close stable orbits are possible.
Why are there no stable circular orbits close to a black hole?
Non-rotating black holes The lack of stability inside the ISCO is explained by the fact that lowering the orbit does not free enough potential energy for the orbital speed necessary: the acceleration gained is too little.
Can something orbit a black hole forever?
For example, unlike normal objects like asteroids and planets and stars, there is a minimum distance from a black hole where a small object can orbit it without falling in. Farther out and you’re fine; you can orbit forever. Closer in, and space is bent so much that down you go.
Can life exist inside a black hole?
So planets could potentially form around black holes, but that’s no guarantee that they offer a life-friendly environment. On Earth, living things are hugely dependent on the light and warmth from the Sun to survive. Without the glow of a star, life around a black hole would likely need an alternative source of energy.
How close could you get to a black hole?
With current technology, about 27000 light years. That is the estimated distance to the nearest black hole, and we have no where near the technology needed to get there.
Can gravity capture light?
A black hole is a region of space where gravity is so strong that nothing can escape, not even light. It might be surprising to you to hear that gravity can affect light even though light has no mass. If gravity obeyed Newton’s law of universal gravitation, then gravity would indeed have no effect on light.
What is the most stable orbit for a black hole?
Otherwise, it generally stands to say that whatever orbits are stable for any large body are also stable for a black hole. Actually, a black hole will be even more stable. All the planets are stars have a complex gravitational tapestry due to density changes due to composition changes.
Are black holes special?
The answer is “yes”, and there are a surprising number of ways to argue this. You will probably want to look at the question about small orbits around black holes in Physics Stack Exchange. At sufficient distances, black holes are not special. Black holes behave the same as any other spherical collection of matter.
What would happen if you collapsed a planet in a black hole?
If you collapse any of these bodies to a black hole, they’ll have to expel their angular momentum. At long distances from a black hole, the gravitational field will be exceptionally constant, and this leads to greater orbital stability. When we’re talking about Sagittarius A* and things like that, we’re generally still in this regime.
How fast will the Earth’s orbit change in 100 years?
Specifically 43 arc-seconds over a century, which is something like 1/100th of a degree… in 100 years. However, since the solar system has been around for billions of years, this can still have an impact on orbital stability. That’s a very minute correction to our conclusions.
