The doco thing, when he said, physics allows you to travel into the future.

If you build a train track around the globe, and put people in the train, and have them go at
a speed just under the speed of light, if they stay on the train for a week and then get off, it
will be 150 years into the future.

You just need to build a train to go that fast, so its a engineering and economic issue, not a physics one.

It is technically possible to go to the future.

Great Scott!
