Aha !
I suppose leakage of energy from our universe to another one would require the 'recipient' universe to be of a similar 'blood type' as ours.
Ie: I guess, in an infinite universe there would exist another universe whose fine tuning parameters could still be within these fine tolerances, I suppose … perhaps sufficiently enough for us to recognise, and maybe communicate with them … but until violation of conservation of energy is observed in this universe, none of this is reality.
I've been thinking since last night. I really appreciate this dialogue with you Rob .. I'm starting to see where the reactions from in others might becoming from. Its easy to assume that we're all off the same playing field .. but clearly, we aren't.
For me, if something is unknown .. that's exactly what it means .. ie: 'unknown'. I get the distinct feeling that others cannot accept the implications of 'unknown'. Filling in the 'unknown' with supposition is fine .. but that doesn't alter the reality that what we don't know, is still not known, in spite of the supposition.
If it is
unknown whether the universe has a reality able to to be discovered by us, then all the supposition in the world ('trajectories' etc), still doesn't alter this. What does alter this, is observational evidence and our perspective afforded by the tools we've developed for observing it and … the means we've developed by using those tools, to manipulate it.
Much appreciate the conversation.
Cheers
