When we travel back in time, does it change the future if you don’t touch anything but travel back?

We really don't know.
There are different theories.
Is there only one time line that is currently being changed by time-travelers?
Or do we create a brand new time-line in which we are a traveler but can effect events?
Or are there an infinite amount of time-lines in which every possibility exists and which we can travel to, thus effecting them?

If you like short stories, try:
[i]And the World Turned Upside Down[/i]
HMS [i]Eagle[/i] is somehow transported 25 years into the past... to the Andaman Sea on December 6, 1941.

Sorry, could only find the link to part 2, but follow it from there.
Not the best bulletin board format,

Somebody, or maybe you, invented a mechanism which allowed you to travel back in time. Which means that [i]events had to play out exactly as they did for that mechanism to exist.[/i]
You use that mechanism to go back in time. Your mere presence constitutes physically touching that point in time (as explained by [@PhpPheonix]. However, your presence in that previous point in time cannot change your future because, if it did, the time travel mechanism would not have been invented.

@NerdyPotato But surely an unchanging time-line would already incorporate that visit to the past. It would be part of that same fabric of time would it not?

@room101 That's an interesting theory, but that means time isn't straight-up linear. The only way for the visit to be written into history is if history was written after the machine was created in the future. So either we're experiencing time in reverse or the invention and visit actually happened simultaneously.

@NerdyPotato Until relatively recently we believed that time is indeed "straight-up linear". Now, we are investigating theories which hinge on a multi-dimensional perspective of time.
If time is linear then it is, by definition, unchanging. Our time traveller went back in time but did nothing which affected the technology of that time. Hence, the time machine he used was still waiting to be invented. And yes, that visit would have been written into history. But probably as a sci-fi anecdote.

Depends on your view of time travel. In one view, whatever happens always happened, so there is no way to change the present. When you traveled back to 1900, you were there in 1900 and those who lived back then might’ve run into you; there’s no changing anything.

I don't think so because you were only there as an observer. :)

Because you weren’t born does it effect your birth@Tinkerxbell
Tinkerxbell · 41-45, F
@MOONAMONA86 It won't as long as you do not touch anything. May I know, why would like to travel back in time? Is it because the present moment is too much?
