You sound excited and I’m sure you will get learned responses, but in the meantime can you explain this concept a little further.

You say, “The Rindler horizon, then, is just that original distance from which we cannot receive new light.” That is true as long as you keep accelerating, which you can do in a thought experiment. But when you relate the Rindler Horizon to the event horizon of a black hole, how do you achieve continued acceleration?

Or what is the point of relating the Rindler Horizon to the event horizon?
