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, 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.

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.

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