If we could use a time machine, would it be better to have one that only goes back in time or one that only goes forward?
The advantage of having a time machine that can travel both into the past and future is that you could potentially change events and create new outcomes. If you had a time machine that went only back in time, you could potentially affect history and cause unintended consequences. On the other hand, if you had a time machine that could only go forward, you may not be able to experience certain historical events or make changes that could lead to different outcomes. Ultimately, the best time machine would be one that can travel both backward and forward in time with complete flexibility.
