I think multiple dimensions may exist. Einsten had good points for the theory. I also keep wondering if there could be new worlds inside black holes. If these worlds do exist, there's a chance that there are beings living there, but it would be random.you think there is a fourth dimension, if so do you believe there are beings living there?
Human beings aren't wired for that. I'd probably run out of intellectual stimulation and end up depressed.Do you think you have the patience and endurance to live forever?
Second option.to add to this, do you think that if you lived forever that the brain would eventually run out of space to record memories and learn? or do you think information be forgotten as you continue to learn?
