Our sun becoming a supernova and swallowing the interior of our solar system will probably happen before we get pulled into the milky way black hole. Space time continuum, interesting. Things I wonder about black holes: Are they round? Or are they just a hole in the fabric of reality? Another thing about space I've wondered is whether or not it is a limitless void, or is there a boundary to what we understand of existence. And if such a boundary exists, well then what exists beyond the boundaries of the universe?
We don't have the lifespans to explore a 5 million light year solar system in person, we as of yet do not have the technology to safely(If safe exists in space) explore space for a long period.
Come to think of it, if we as a species are still around when the sun finally begins to run out of fuel, I'm sure we will overcome it. We'll build our own death star and become planet conquering Necro Mongra's.
