Time travel isn't realy possible. No time travel is accurate.
I think Tenet or Primer might be the closest to actually plausable. And they don't realy match what people think of as "Time Travel".
My head canon is the only viable timeline is the one where time travel is never invented.
We are all time traveling though... Into the future at 1 sec per sec.
Tenet plausible? Bruh, what?
You also change the rate at which you move forward in time depending on the local gravity and speed.
It is technically possible to accelerate so much you can travel forward in time at a nearly infinite rate.
You just can't go backwards in time.
Yes. Exactly.
Tenet and Primer both use the exact same time travel mechanic.
Step into the machine and you start traveling into the past at a rate of 1 sec per sec. You're traveling through time at the same rate as normal, just the opposite direction.
Tenet is complete nonsense
It's realy not. It's a completely consistant, well thought out conception of time travel. It only seems like nonsense because it's so different from our normal experience.
I didn't say it wasn't consistent, it's just nonsense
Then I don't know what nonsense means
I’ve not seen either of those but I always imagined if time travel to the past was real, it would be circular, as in, in 2027 I travel to 1950, but right now in 2026 I haven’t travelled yet, but if I were to look, I would have already been in 1950 in the worlds past but my future. Eg Harry Potter, Timeline, etc
Primer is a great flick for thinking the logic through. Unfortunately you'll need to watch it a few times at the very, very least, to get all the interthreading plot lines. But it's fun.
