I'm just curious, what would it really take to travel to a parallel Universe? How much energy and what kind of technology would enable a person to travel to other Universes?
 
Astronomy news on Phys.org
There is no evidence whatsoever that "parallel universes" exist, so your question in the realm of science fiction, not science.
 
Really, it's not even science fiction, it's straight fantasy.

There's no scientific basis for how we might do this; it is left to wild speculation.
 
I would relax the certainty against parallel universes, but, not the certainty they are intrinsically undetectable.
