Isnt the outskirt of the Universe an invisible Horizon where the escape velocity is equal to the speed of light?

This sounds like an interesting idea which I first heard watching "Cosmos," the Carl Sagan series. Are we really inside a big black hole--part of some multiverse?
No answer, just a beautiful idea.

Hi. The "event horizon" surrounding a black hole is where the escape velocity is equal to the speed of light. Any "event" happening there would not be visible, ever. It is called a "horizon" because you can not see past it.
