    The beauty of a time machine though is even if you take a really long time to build it, you can just go back and build it faster.

      That’s gotta be a good sci fi novel. Society invents time travel, and continuously goes back in time to accelerate their progress by uplifting their ancestors.

        I’ve thought about ubiquitous time travel resulting in humans being able to choose not just where to live, but when, bringing their technology with them. What a mess that would make with the timeline!

          You would actually physically be rolling back the entire universe, reverse-entropy style. So, only one person could do it, and they would basically be god.

        Or every time society invents a time machine, the world ends and somebody has to come back and sabotage the effort. So humanity hits a wall in progress that it can only pass by not focusing on time-physics.

          That kinda sounds like the plot of the cancelled Netflix show Travelers, to be honest.

          It was a good show, and the main characters were always going against other people from the future trying to foil their purpose for going back in time in the first place.
