Fascinating. I greatly appreciate such thinking. I have often dwelled on the concept of the other side of a black hole.
In contrast to the concept - after ruminating for a minute or two - my mind tends to believe that they would have found the event horizon - or whatever term they assign it from the inside - by now. It should present as a unique, obvious anomaly in space.
But if true, it could certainly explain a number of outliers in the science of astrophysics...even if their brains are still too small to wrap around such a concept today.
Frankly, it is very plausible that our ‘universe’ is borne of the ass end of a black hole (though not ‘inside’) because - YES - ‘space’ is THAT big (not finite like the supposed smart people proffer).
If we ARE in a black hole, and assuming that ALL black holes are individual universes, then could the event horizon of those black holes be considered as “Cosmic Foreground Radiation “?
I just enjoy looking at the stars at night, and our own star during the day. Just how far are they going to go with this stuff…..?
