We can't exclude anything that is even remotely scientifically possible.  In fact, I'm not ever sure we can exclude anything that is currently impossible.  All it takes is a discovery that extends our knowledge.

I've also always thought that Hawking just threw that "we've never been visited by time travelers so time travel probably doesn't exist" out there as a beginning discussion point.

I didn't get a chance to meet the dude so I can't be sure of when he was being serious or when he was just simply taking the piss out of people, I have heard he was quite the prankster.

The libraries are full of learned academic texts "proving" how many things in existence today are completely impossible.

But only allowing birth dates up through 2038 seems a bit short sighted, or maybe he knew something...

My only proof against time travel is that no texts describe the crucifixion as attended by millions of people. And you know that as soon as there is time travel, Cooks will schedule tours.

Unless you can't travel back in time to before you turned on the machine.  You can go forward and go back to where you started but into the past isn't possible.

Going forward is easy. Anyone with enough reaction mass to approach relativistic speeds can do that. It's going backwards that violates what you might call temporal entropy.

The great conundrum, it is possible to find solutions in general relativity that allow for it, but the solutions require conditions that may not be physically possible.

Wait, aren't I travelling forward in time whether I like it or not?  I'm starting to age and I'm not sure I see any value in accelerating my journey through time.  Hell, there's too much I miss already because it bores me.

The passage of Time is an illusion.
