  • Even more specifically, if we are talking a temporal teleport, then this shouldn’t be a surprise. Most mainstream fiction uses teleports for time travel, pop out of one time and into another without experiencing the time between. As opposed to the device Farnsworth made in The Late Philip J. Fry, where they actually just change speed through time instead of skipping through it. In the latter case, you shouldn’t have to worry about this issue at all. But with a teleport, any teleportation device is simultaneously a temporal and spatial teleport, due to causality and the nature of spacetime. So any teleport would need spacetime coordinates, not just spatial or temporal coordinates.

    Sapient, not sentient. Sci-fi has co-opted the word, but sentient basically means able to feel emotions. There are plenty of sentient species right here at home. Sapient is the word sci-fi usually wants, there are no known sapient species aside from humans. Though some may argue that a couple other animals may qualify, it’s a very fuzzy concept that is hard to identify with a being unable to communicate abstract concepts.

    If it slowed down it would get closer, not further. The truth is, any orbit is only stable given a specific timeframe. The longer that timeframe, the less likely any given orbit is to remain. The moon has just a little bit more speed than the Earth can hold onto, so it is in an extremely slow escape, and always has been.






  • I think so long as you maintain consciousness that issue is fairly null in this particular circumstance. There’s lots of tolerance for changes in thought while maintaining the same self, see many brain damage victims. So long as there is minimal change in personality, there are lots of other circumstances that have a stronger case for killing one person and having a new person replace them due to change of consciousness, imo, I don’t think most people would consider a brain damaged person killed and replaced by a new consciousness, or a drug addiction with radically altered brain chemistry, etc.






  • Well that’s good, because it is the least efficient walk. It’s even worse than binding your hands to your sides. It makes a kind of intuitive sense, but shocker, the way we’ve evolved to walk most comfortably is the most efficient. We swing our arms in part to reduce angular momentum. Anti-swing walk, swinging the same arm forward as the leg that is moving forward, not only fails to bleed that momentum, it adds more of it. Which we then need to spend even more energy to counter, with less efficient muscles. It’s the worst of all worlds. The only practical reasons to use it are to increase the intensity of your walks, or if you’re into some martial arts/kendo that relies on it.
