  • They could have forgotten about the position setting all together.

    You’re assuming that the time machine would just change the time and keep the position but there is no absolute reference frame, so the time machine should use some reference frame in which it keeps the position constant. It would then be common sense to have the time machine keep the position relative to the earth. Anything else would be pretty dumb, unless you want to use your time machine also for space travel to other planets.

    why the suns position

    That was just an example. It’s either the sun or the center of our galaxy, or some other reference point so if it wasn’t the earth then the sun is the next most logical option.






  • Near my university there was a great desire path because the bike lane went around a patch of grass for no reason. Their ultimate response was to let the company that was digging up a place for a new hospital building dump all of their excess dirt on the grass patch.

    So they created a big dirt mountain that covered the entire grass patch and now the only choice left was to follow the bike lane. In the meantime they removed most of the dirt mountain but the desire path hasn’t recovered yet since there’s now a lot of overgrown plants.

    I really hope it returns soon because it saved me the full 5 seconds I needed to get to my classes in time.
