    To put some perspective, it takes 225,000,000 years for our solar system to orbit the Milky Way. Meaning it’s gone around almost 18 times. Humans have been here for ~200,000 years, or under 1/10 of an orbit. We’ve barely been here.

    Most of these galaxy's we are seeing generated that light billions of years before the sun existed. Probably billions of years before the super nova that made all of the atoms that make everything we see were fused together.

    In ~4.5 Billion years, Andromeda will collide with the Milky Way. We won’t see it because the sun will burn up the earth as it dies in 3-5B years. Let alone there will be a handful of extinction events as we orbit the galaxy.

    Given how we perceive time, it’s hard to fathom we’ve only been here for ~0.005% of the time this planet has existed.

      I'm an optimist. We'll see it from somewhere else.

        Maybe. But time and evolution will drastically change humans over 2B years.

        At least we would need a “Wally” kind of space craft to get to another place to live. It will take many generations of humans to get anywhere, given we can’t come close to traveling at the speed of light. The ultimate Noah’s Ark.

          As you say, we will be vastly different. We may not need a ship. We may not even need to "go" anywhere. Assuming we can become unstuck in time the way we are in space, we may just differently when. We may already have.

            Not sure how we prevent the sun from running out of hydrogen, and then expanding in size to envelop the earth.

            Or how to violate known physics.

                We've been seriously investigating physics for 500 years. Now let's do that 40M more times.

                  They are also the one of the key reasons people realized that there needs to be an upper limit to wealth.
                  Rockefeller was calculated to control 3% of the wealth of one country. Mansa Musa supposedly controlled half the wealth of half the world.

                    until only very recently, flying was but science fiction. Even science fiction has been around for a short time. Writing barely longer than that. Language barely longer yet.

                    Our definition of "Physics" is meaningless and has no bearing on the actual laws that govern the universe. "Physics" is only fixed on extremely short timeframes.

                      Except there have been flying animals and insects since well before humans walked the earth. The only thing preventing humans from doing it was understanding. We even knew it was possible to go faster than sound before we did it, as bullets had been doing well before the X-1.

                      Traveling faster than the speed of light is quite different than that. Mind you, we have been accelerating particles to very close to that for decades, and understand the energy required to do that for sub atomic particles. Time won’t change that.

                        In our current understanding, yes.

                          Exactly.

                          Physics isn't reality, it's twice removed: it's a model of the metaphysics that is prevalent. We'll keep gathering more data and we'll keep creating more comprehensive models and like I said, I'm an optimist. We'll figure it out.

                              We've been gathering data for millennia. Most of our theorizing, until quite recently, was a colonoscopy on the Angry Man in the Sky.

                              But let's give us 10k years to be generous. OK. Now we do that 2,000,000 more times. With our technology and our ideas increasing in their power and explanatory value exponentially all during the time.

                              We aren't even ants yet, we are bacteria. We aren't even flatlanders, we are barely a point with no dimension.

                                Ok. But the models are converging on some pretty drastic laws pertaining to speed and energy relative to long distance space travel.
