Scientists express surprising confidence about the possibility of time travel. while they acknowledge that we don't possess the required technology, they do point out that it's just a question of engineering since it is clearly not impossible (hawking & mlodinow, 2008). if society did have access to technology that enabled travel to the future, how exactly would we use it?

The core reason to travel to the future is to find out what will happen, and if it's the case, to avoid or maintain that future.

Explanation:

A time traveler interested to find out what happens in the future must keep in mind that it's an enormous responsibility. The traveler will have the opportunity to know if the future will be good or bad. Then, when he comes back to his time period, the traveler must work to avoid or maintain the future he saw. There's no other reason to travel to the future.

you should think about the answers you give and expect the same form your questions.
