OK, and have some lucid dream, for in there we can be God and do anything, even breaking the laws of physics and floating though the air.
Here's some more breakfast food for thought, even if it repeats a bit:
It’s only those things that we don’t know are possible that we can’t say for sure. We’ll have to wait for better computers to figure it out, a daunting task since even a state of one change of one atom requires a precursor form and a series of prior events cascading backwards through infinite time and across infinite space.
However, there is still every possible combination of matter and energy; it’s just the resolution that remains unknown. Think of morphing objects together; the resolution is like how many intermediate stages there are (possibly infinite, but who knows).
I am calling this notion ‘supercontinuity’. It says that any object known to us, whether a galaxy, planet, person, or whatever has a prodigious number number of very similar examples in space somewhere, varying along every possible parameter. This supercontinuity must be true by virtue of the universe’s permutational variability. The only question, still, is what is its resolution: how closely can these (separated) instances of any given type of object resemble each other?
For example, even on Earth, between human races, the percentage of DNA separation is less than .1 percent (2% between chimps and humans). There is even a web site where one can look up their so-called ‘doubles’ on Earth. Identical twins have identical DNA, but differing experiences (so we are not yet at the stage of identicality). To be exactly the same, they would have to have the same molecules and quantum states.
But, heck, there is all of space and all of time; thus, it is very likely, even certain, that at least some intermediate states of a certain resolution exist somewhere at this very moment, and always did and will at any given time. If there is not exactly another Earth, surely there could be one whose only minor difference was one unnoticeable at the atomic level.
