If fiction has taught us anything about time travel, it’s that changing the past tends to get …complicated. Would you do it anyway?

Going to the future doesn’t pose the same risk, though you also wouldn’t know what you’re getting into prior to arrival — what if the year 2147 is an especially unfriendly one and it ends up being a one-way voyage? Maybe time travel is a bit like camping: caution is paramount and it’s probably best if you leave no trace of your stay.
