Question: Is time travel going to be possible on day?

Hey
I agree koalas do rock but they also skink!
Anyway thanks for the question. Time was first measured by sticks or rocks in the ground acting as sundials and by monitoring the stars. There are lots of different kinds of calendar some based on how the moon or the sun or random stars. So there are lots of ways to tell time all of which are pretty clever really. However if you think about how we tell the time then people time travel all the time. If I was to travel from Australia to here I would arrive a day before I left Australia this even works for places nearer to us like for example France. I think having a past to learn from is very important and don’t like the idea of people going back to change it so in that sense I hope not 🙂
