I thought about this earlier. We know that we are *stretching away from certain objects in our universe faster than the speed of light. Therefore we are behind an event horizon for those objects, we are outside their future light cone, no information can ever pass between us and them. Therefore we live in a black hole?
 

*stretching as in a sense that the universe is expanding, we are not physically moving through space away from each other FTL.

 

EDIT> but what does it have to do with this topic? We are offtopic, Dave!

Just to stay off topic for a bit longer...

A black hole event horizon marks the point where gravity is so fierce, light would have to exceed the speed of light in order to achieve the escape velocity necessary to get away from the black hole. As light can't go faster, it is the cause of not being able to see what it is going on in that particular region. 

The expansion of the universe at a rate greater than the speed of light is another cause of not being able to see what it is going on in a particular region.

In both cases the seeing problem is a limitation produced by the light speed barrier but the regions are not the same thing.  One is a hidden region because escape velocity is higher than light, the other is a hidden region because it is moving away from us faster than light can come towards us.

The qualities of each region are very different, the only commonality is that we can't probe those regions using light. So, no, not being able to probe those regions is frustrating but not evidence that we live in a black hole.
