In our universe today, we do not know if it is possible to contact or even perceive other universes or realities, but just like out of nothingness our reality was born, certainly out of nothing other -1s are born every day creating universes out of 0s....negative energy is still energy, right? And if you put energy into nothingness, something starts, right?
This, if I understand right, our universe is not last nor first, we are but an instant in an infinite list of universes being born and dying in the glimpse of an eye, but this glimpse is perceived longer by us.
If so, would it be possible for one of those universes to be born with a connection to other universes, a connection that allows matter and light to travel from the universes without them fusing?
