Finally, the one thing preventing time travel solved.

We’re all time travelers here. That is, unless you’re a photon. Are you a photon?

Yeah, I don't know. You've got to be really correct if you're going to go against Einstein and Hawking. The article even flip flops on weither time loops can exist or not.

Yeah, losing entropy is kinda not the point of time travel. What value does time travel have if no one remembers it?

As a layperson, this disenchantment makes it more plausible.

It kind of is. The arrow of time points in the direction of increasing entropy.

So I can go back in time and become my own grandfather? Gross.
