    And to add the cherry on top, should you ever reach his arbitrary speed limit, it distorts time itself. Even if you flew through space at c for a little weekend getaway, you’d return to a now foreign world only to find time had skipped forward +2,000 years, your entire family and social circles long dead from old age with societal and technical advancements beyond what you could have ever thought possible, completely isolating you. You’re now doomed to live in an unfamiliar world where not a single human speaks your language nor can they relate to you in any meaning way.

    AKA, gods speeding ticket.

      I have a solution for this: When you travel somewhere, travel with everyone’s mind at light speed. You see we think about lightspeed wrong. It’s meant for whole species to migrate. Not 1 individual.

      Another alternative is just take a snapshop of everyone’s minds at that point, then let them continue living even with your snapshot. When you return you pick back off where you left off. Living in your own dimension. The other dimension is long gone but you miss nothing.

      What is observable is constrained by cause and effect. To see something, information must come from there to us. That cause and effect relationship cannot happen faster than lightspeed.

      We therefore have no evidence for anything other than the observable universe. Claims about anything else run into Russell’s teapot issues. We can speculate, but it’s ultimately nothing more than a story.

        The observable universe is constantly expanding as the passage of time allows light to reach us from more and more distant parts of the universe. So it’s less “we don’t know what’s outside” and more like (to a certain extent) “we have to wait and see.” And there’s nothing we’ve seen to indicate that these external regions that are being revealed are anything but more of the same kinds of things in our inner region of the observable universe.

      True, but there is thought to be a finite amount of matter + energy, which cannot be created or destroyed. And since it is spreading out from an original dense point, it stands to reason that there would be a vacuum area that it has not reached yet.

        That’s not at all how it works. In particular, it didn’t start from an original, dense point. It started everywhere, with nearly uniform density apparently infinitely in all directions. If the Universe is boundless, there is no reason to suspect the material it contains is not equally boundless.

    The universe is actually expanding at a rate faster than the speed of light. There’s only a finite distance we’d technically be able to travel if we were to leave right now.

    This is assuming that the universe is for us. It’s probably not for anything, but to the extent that it is for a kind of life, it might not be us.

    To be clear it’s lightspeed in space time, we “just” need to get rid of time to conquer the space.

    alcubierre drives are (theoretically) a thing. wormholes are also a (theoretical) thing.

    we could just bend space.

    Let’s say we reset everything today, wipe out everyone’s memory. God will be forgotten, science will still exist. People will figure out science sooner or later.

      Science laws won’t cease to exist, but if you wipe out everyone’s memory, their knowledge of that science will cease to exist - so they’ll have to figure it out from zero - and there’s no guarantee that there won’t be another placeholder in a sense (i.e. what religions have been historically) for what’s yet to understand.

      Edit: maybe it’s more accurate to say science laws would cease to exist, but won’t cease to work; they would cease to exist in a formulated way (in that hypothetical memory loss) since they were put together by humans.
