Exploring Matter and Black Holes Beyond Event Horizons

[ABHoT]

I am believing that event horizons refer to where light can no longer escape the gravity of a black hole. What about everything else that moves at less than the speed of light?
If a small moon winked into existence at some point further out than the event horizon with momentum that was sending it away from the black hole (if you could believe such a thing), would it get sucked back into the black hole like light? Does matter get sucked in faster than photons of light? Is there a separate 'event horizon'-like distance where matter can either escape or fall back in?

Ah. Just seen the black hole video.

ANY object within the EH will be unable to escape from the black hole. Things farther away than the EH may or may not go into the EH depending on initial velocity.

With the moon, it would depend on it's initial velocity, like Matterwave noted, and the strength of the black hole. If the initial velocity is greater than the escape velocity, it's good to go. As for matter and photons, well matter has inertia, so you can naturally make conclusions off of that. There is only one event horizon, & beyond that, as far as we know, there is no hope of getting back out, except Hawking radiation.

I can say that the concept of event horizons is a fundamental aspect of black holes and their extreme gravitational pull. You are correct in stating that it is the point at which light can no longer escape the black hole's gravitational pull. This is due to the immense curvature of space-time created by the black hole's mass.

However, it is important to note that the event horizon is not a physical barrier or wall that prevents anything from crossing it. It is simply a boundary beyond which the gravitational pull is too strong for even light to escape. This means that anything, including matter, can still enter the black hole beyond the event horizon, albeit with a very high probability of being pulled in.

In regards to your example of a small moon with momentum, it is possible that it could "wink" into existence beyond the event horizon and continue moving away from the black hole. However, the closer it gets to the event horizon, the stronger the gravitational pull will be and it will eventually be pulled back in. This is because the pull of gravity is dependent on the mass of the object and not its speed.

As for your question about whether matter gets sucked in faster than photons of light, the answer is no. In fact, both matter and light will be pulled in at the same rate, as they both experience the same gravitational pull from the black hole.

Lastly, there is no separate "event horizon"-like distance for matter. The event horizon is the same for all objects, regardless of their mass or speed. However, there are other factors such as the size and rotation of the black hole that can affect the distance at which matter can escape or fall back in.

In conclusion, the concept of event horizons is a crucial aspect of understanding black holes and their effects on matter and light. While matter can still enter a black hole beyond the event horizon, it is important to remember that the event horizon is not a physical barrier and does not prevent anything from crossing it.
