re: #227 DaddyG

I’ve seen both of those shows with my kids. Hawking talks about it being theoretically possible to travel forward in time based on the behavior of particles at the quantum level but doubts we could travel back in time due to feedback issues and paradoxes.

He even talked about a party he threw for future time travellers where no guests showed up.

The shows are very well done and based on solid science and mathematics.

I am certain they are. Hawking is wonderful. It is the silliness of Fox I am giving richly deserved grief to.

N.B. one need not invoke quantum mechanics to discuss going forward in time at a faster rate (which is the same thing as slowing down how time passes for you). You get that directly from special relativity.

The transformation is not even hard for a middle schooler to calculate - it’s just algebraic.
