Time travel to the past is impossible. Time travel to the future is pretty easy by moving at relativistic speeds due to time dilation.

Regarding what you said, yes that's something that's often omitted in time travel stories, but sometimes they mention it too.

We time travel at the rate of 1 sec per sec

Right. We are all time traveling right now. We are just bored with the same old constant speed.

But there are some methods to change the constant speed that we time travel.

If you want to slow it down, get yourself in a car stuck in traffic. If you want to speed it up, oversleep when you have to get up and get ready for work.

It's not really time travel. Time just moves slower for the person affected by heavy gravity or moving at the speed of light.

Sure... but I mean.. if you went to sleep and woke up in the year 4500, it would feel a lot like time travel, right?

It doesn't matter what it feels like. It isn't time travel. That's like saying you time travel 8 hours into the future when you go to sleep because you didn't perceive those 8 hours.

Which is actually perfectly valid from a certain perspective. But I think your simile is not really accurate... in the case of time dilation your entire presence is not experiencing time at the same rate, which is simply one method of time travel. With sleeping the time travel is purely experiential.

We don't call it time travel because it's too familiar - but it is, in a way. We're all travelling through time, all the time. Or it least it feels like we are.

I mean, say I made a ship that produces WARP SCOOBY-DOO fields that distort the flow of time, and when I get in it, press a button, and get out, I'm in the year 4500.

But when I get there, some bald guy is like "oh, you weren't time travelling, you were just in STASIS for 2500 years". I'd dramatically tell him to "STEP OFF MY TIME BISTRO" - but how would I prove any sort of difference?

What is the real difference? That the ship was sitting there, with me looking frozen the whole time? Is that what counts? Would it make a difference if it was cloaked behind the scooby-doo rays?

What if I got in the ship and then got out in the past - would it matter then that the ship was sitting there with me frozen inside "during transit"?

I’m with you. People are arguing semantics without ever defining the bounds of this conversation

That is time travel. Similar to using cryogenics, you’ve effectively skipped over x amount of time into the future.

But you haven't skipped over it. It still happened and your body was there for the whole thing. Your consciousness simply wasn't able to perceive it.

If I fall asleep and wake up in the year 3000 (something I never could reach in a normal lifespan), I would say that’s time travel. The end result is winding up in a time that is not naturally my own.

If you lay there for 978 years before waking it. It absolutely isn't time travel. It can appear that way to you. But it isn't. Your body simply laid there for 978 years.

Agree to disagree, but Stephen Hawking used the term “time travel” to describe this very thing in Into the Universe.

You would appear to time travel to others looking on. NDT explained it well.

Something appearing to be the case doesn't make it scientifically true. Magicians have made a living out of things appearing to be the case that aren't really true.

Something to consider: Richard Feynman proved and demonstrated that an action in the present can affect the past.
