Simple question by jacob66. Do you think time travel to the past will ever be possible?

How about a language that's circular (maybe like the text in the video game Outer Wilds)? Or the one in the movie Arrival.

Yes ,I think it might be posible .
(On a subatomic level)but not feasible as seen in movies. Just like the typical example of "throwing a tennis ball through a wall " . It isn't imposible but it won't be happening anytime soon . 😢

My answer is yes. Not now, but maybe far in the future. Who knows?

Time machine, anywhere door, magic pocket.. Would love it if I'm still alive when Doraemon's machines are invented someday. 😂

Pretty sure no. I'd love to say it's because we've never seen any people from the future, but honestly, I think it's super complex and that humanity will have killed itself long before it has reached that level of technology to assure semi-achieveable time travel.
Freezing people however, stopping their time and getting them into the future? Now that's another story.

I think that it may be possible to recreate images of the past that would be akin to observation-only time travel some day (we're nowhere close though, no one even has a theoretical approach) but true travel to the past is definitely impossible, or we would've seen it by now (someone coming back here). In fact, if it was actually feasible, society would be full of time travel already. There'd be no reason to limit it, since regardless of the energy requirements, you could gather more energy by going back to the right time.

So yeah, causality will be intact in our universe. Interactive time travel is definitely impossible (but observation-only pseudo-time-travel may be possible).

Nope. Never ever. I'd loooove to be able to time travel, but alas, that'll definitely never happen, I have absolutely no doubt about that. Sad, but we must accept that there are lots and lots of things humanity will never be able to achieve. And that's for a reason. It's better that way.

There are so many things in the universe we have not yet seen or just don't understand, so it's hard to say that it would be totally impossible... I mean, there is quite a lot about THIS planet that is beyond our understanding.

About that we would have seen a timetraveller if they came... Why would you notice if 7,861,504,618 people turned into 7,861,504,619. I mean unless they actually pops into existance right in front of you how would you know? I've met quite a lot of weird people...

my understanding is that yes it's possible, but the energy needed to do it is not feasible without something akin to a dyson sphere, and even then, you could only travel to the point that the hole was made/maintained.
