A mind-boggling proposition. It challenges our theoretical thinking process beyond imaginary possibilities. It's already a stretch to picture our universe in its entirety, where its boundaries are, let alone what may exist beyond these boundaries. It makes it abundantly clear how much we don't know. The only way we'll ever get absolute proof of any theories what happens at the end of time is by getting there. That would require travel at many times the speed of light. This seems physically impossible. The mind twister in this context is time itself. The question becomes is time even real? In looking across the universe the question evolves, is there really a beginning and an end of time? If so, then it should be possible to find a place certain for each. The truth is, such places may not exist. The idea of time originates with the big bang. We measure the time via the expansion of the universe that presumably is the consequence of the big bang. What if there never was a big bang? According to an alternative theory, the big bang could've been the effect of a collision with another substantial universe that shook up everything we can see. This would indicate that time is infinite, no beginning, no end. Just a constant ongoing destruction and renewal process, where things get rearranged into new things, a constant metamorphosis of matter. Then the question arises, is what we can see all there is? I think that we can only see a fraction of all there is, like a slice of a pizza. The rest is invisible to us. In our intuitive thinking, if it's not visible, then it must not exist. Wrong. We already dubbed the invisible stuff as dark matter. What if we could see this dark matter with our own eyes? What would the universe look like then? And, what would it take to make such an expanded universe visible to us? It's possible that if we could see the dark universe, we could also see shortcuts how to get to other places within the entire creation in an instant. Perhaps the darkness is not really dark at all. It's just beyond the light spectrum our eyes can process. To clear that up we need to understand how human eyesight developed during its evolutionary history. It's conceivable that our eyesight was different 50k years ago. After all, eyesight is a reconstruction of reality by our brains based on information extracted from our vision process. Perhaps it just takes an adjustment in our brains to make the universe fully visible to us. Instead of looking outward for answers, perhaps the answers are already within us. Why not? After all, we're made of the same stuff we can see out there, even the currently invisible stuff. That would make it plausible that we already know everything about everything, we're just lacking the key to unlock it.
