wormhole?
Overthinking all these possibilities, I believe the existence of a wormhole could be real. I expect it's related to quantum entanglement. How could we see a difference in it when it is the same phenomenon?
Again, this seems magical and looks impossible. But consider what we learned from Einstein and visualized with Minkowski's diagram: an event occurring in a certain spacetime is different for an observer traveling at a certain speed. Just add gravity to it. So, suddenly, an event can occur at two different times and different places? Or is it the experience of a possible wormhole?
Then, the thought of quantum entanglement, as mentioned, is related or might be the description of a wormhole. (Much to think about! 😊)
