No doubt each black hole has a multitude of event horizons nested within each other. For an object with a speed of 1000 mph, the event horizon of a BH is fairly large and if the object strays within it, it will be drawn in. For a greater speed it can come closer and for a lesser speed it must follow a trajectory that will take if farther from the BH at the closest point. The EH that counts the most is the one for light. Are you saying the so called double EH has two both of which are for light and if so, how does that work? Obviously you don't know.
You're confusing escape velocity with the event horizon concept. It is true that for an object that starts with an initial velocity of 1,000 mph, there is a certain critical circumference (of a sphere centered around the black hole) from which that object would not be able to "escape" (in the sense of never falling back into the hole).
However, such an object could then try to accelerate away from the black hole, using rockets or whatever, and it would be able to escape. For any distance from a black hole's event horizon, there is a certain critical speed below which an object could not escape, faster than which an object could escape. That critical speed would be the "escape velocity". However, it must also be pointed out that at any distance outside a black hole, for an object travelling at any speed less than the escape velocity (including sitting still, just before freefalling into the hole), that object could exert some level of acceleration (perhaps a very large, but
finite amount of acceleration) and escape the black hole.
At the event horizon, it's not just the fact that the "escape velocity" is the speed of light. This fact in and of itself doesn't fully capture the essence of the event horizon. What really matters is that, at or inside the event horizon, no amount of acceleration could change the fate of that object: it will never escape. For an object at 1.0001 times the critical circumference (of the event horizon), it could escape if it could expend enough energy. For an object at 1.0000000001 critical circumference, it could escape if it could expend enough energy. The fraction of energy that would have to be expended would be over 99% of the object's rest mass energy, but it could be done. But at and within the event horizon, no amount of energy could be expended to get the object out. There is only one event horizon in this sense, for a spinless, chargeless black hole. Many escape velocities at various circumferences, but only one event horizon.
I claim no such authority or understanding but we all have the right to question what is presented to us. Those who doubted that the earth was the center of the universe a few centuries ago were treated with much the same scorn you heap upon doubters right now. People now as then were expected to accept many things on faith.
The first difference you seem completely ignorant of was that those who doubted that the earth was the center of the universe had good reasons to. You play the part of the skeptic for skepticism's sake, not because you have good reasons to doubt anything. So far you haven't presented anything that might be confused as an educated objection to the current understanding of physics. You've only displayed your unerring faith in your own ignorance to help you understand the world. I pity you, and I don't say that to be mean. Honestly, what is your intention here? It's certainly not a pursuit of the truth.
