  • Everything bends when you move it, usually to such a small degree that you can’t perceive it. It’s impossible to have a truly “rigid” material that would be required for the original post because of this. The atoms in a solid object don’t all move simultaneously, otherwise swinging a bat would be causing FTL propagation itself. The movement needs to propagate through the atoms, the more rigid the object the faster this happens, but it is never instantaneous. You can picture the atoms like a lattice of pool balls connected to each other with springs. The more rigid the material, the stiffer the springs, but there will always be at least a little flex, even if you need to zoom in and slow-mo to see it.


  • While it is true that will always result in a winning line, it’s not true that it is the only way to force a win. Half of their moves will allow you to play adjacent to you starting corner towards an open corner and still force a win, as long as their first play isn’t the opposite corner or any of its 3 adjacent spaces. In fact, if they start in one of the adjacent sides or non-opposite corners, you have 3 winning moves. If they start on a side, you can take either the open, non-opposite corner, the side leading to that corner, or the middle. If they start in a non-opposite corner, you can take the first two moves above, or the opposite corner.



  • 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.
