What if they've invented invisibility and we just never noticed~?

evidence exists that may prove we will one day create time travel; check dis shit out

Also this is implying that time travel would exist in both directions, which it would not.

The faster you're moving the slower time passes. Couldn't that be considered a form of time travel?

Time travel could only exist to the point of creation of the time machine eh?

That really doesn't make any sense though. Assuming a time machine was invented; what would stop people from traveling to a time before the machine was invented?

Simple. Traveling before there was one could alter time in a manner that the time machine is no longer invented.
Read Ray Bradbury's "A Sound of Thunder". Good read.

Something along those lines. Say they cough while back in time. They could carry a disease that hadn't existed yet, or had become extremely mutated so the "modern" medicine in the era they went to couldn't cure it. Then all of mankind is extinguished.

We can already travel forwards in time very slightly. You just need to be going at supersonic speeds for a little while and you'll be a few milliseconds into the future or something like that.

That argument hinges on the assumption that travelling backward in time stays in "our" reality/timeline, rather than creating or entering some sort of separate reality/timeline.

So basically, the idea is that even if humans invented time travel they'd be too scared to use it? I, for one sir, completely disagree with that theory.

Ah, didn't see your post. But yeah, it's arguable that we have the beginnings of a method of proper time travel here. Getting the required speed for any significant travel would be a big problem, of course.

Good point. It would be innately alternate if you think about it. Simply because of your presence.

What's interesting is that we can already look into the past by billions of years, because we see distant galaxies etc as they were before, not as they are now.

I've always found this really interesting. Everything you observe is in the past. If you look at something a metre away from you, you're actually seeing it 10 seconds in the past. :p

Why would we know about time travel?
Wouldn't they have a code to protect as not to affect their future timeline?

I don't think so.
They'd just bring back the info to the future and rewrite their history holo-books. It wouldn't really interfere with anything.
Oops forgot the future's future. nevermind

New theory:
Time cannot be changed and the universe is as it is because the changes happen. Maybe.

Makes sense in my mind but hard to explain in words.
Say someone goes back from Future time - In a line like so Past - - - > Current - - -> Future - and changes something in Past time, and returns to the point in spacetime where he started, Future time.
Nothing will have changed because the universe had already built on the changes made in Past time to create Current time and Future time. The changes made by the traveller are already integrated in the timeline before he makes them.
The change is an event in the Past, already known of in the Current time, and already established before the traveller departs from the Future to make it.
Or something like that.

The current time is as it is because of every single accumulated change travellers have made.
The current time cannot suddenly shift and become some apocalyptic wasteland because some traveller messed up the missile crisis because that change didn't happen, and there's no possible way it can because all traveller changes of the past are already established.
You can't add changes because all changes that were made have already happened.
I think the same can be said for travelling to the future and making changes because at some point it will be the past where new changes cannot happen.
Or another way of thinking of it:
View time from start to end(??) as a big line all happening at once.
All changes made by travellers would be a static set of points on the line and cannot change as every single one has happened. None can be added. If it happened, ever, it's already there.
No point in time can change because it's the accumuation of all history and traveller "changes" before it.
Or just stop thinking about it because it's a total mindfuck in depth.

I think I get you. And if I understand you correctly I think you agree with my OP. If time travel ever existed at all, we'd already know about it.

Well not necessarily that exact point.
There probably is a code of conduct for travellers and none ever slipped up and revealed themselves as travellers.
They probably still messed with shit to make everything as it is today.

Maybe a time machine is far too difficult for any earlier version of our civilization to use it, so sharing the tech might be useless.
Dunno.
