Sorry if this is just a stupid question from a hobbist but it truly has me stumped. Or maybe I just have been taught by oversimplification.. Anyways! The question:

At the event horizon not even light can escape... but anything with mass should!?

Essentially my question boils down to: Is there a limit to the amount of energy that can be given to a mass as speed? Or asked in another way can momentum be increased without limit?

As I understand mass can be accelerated with indefinite amounts of energy approaching the speed of light. Also giving that this mass would need the opposite amount of energy to stop.

Given an object for example a bit of non-interacting dark matter accelerated standing still right next to a black hole should reach in AND end up on the other side outside the event horizon. Energy preserved. Essentially not caring about the event horizon. Starting as far out as it could be attracted by it and gaining the speed to end up on the other side equally far from the senter of mass of the black hole. Yes?

The same applies to normal matter. Approaching the black hole with sufficient momentum. Never reaching the speed of light but having enough energy that the black hole can not hold it. As long as it does not collide with stuff... it should be possible to skim into the event horizon and out as long as you HAVE mass? The pull of the black hole must be limited but as long as the energy you can put into a massive object is not you must be able to visit the inside of the event horizon and get back out...
