In the way you're thinking

Short answer: no

Long answer: No, probably not - Obviously we can't say exactly what we'll find out/discover/invent in the future, but from everything we know so far the universe has rigid and strict laws about anything remotely like that.

We don't even know if the "past" or the "Future" exists. We assume just because we have a recollection of places, things and events that they must be somehow tangible or still exist somewhere.

That's a huge assumption - For all we know Time could be like a burning candle, Everything below us is unlit and doesn't exist in time yet and anything above is gone.

And you can't un-light a candle to exactly what it was before. Entropy doesn't work that way.

OK, maybe we cannot travel back in time, but could we observe the past directly in some way? Could we livestream the past and beam the stream forward in time in some way?

Technically, yes.

Realistically, no.

Have one gigantic galaxy sized & perfectly calibrated refracted mirror 10 lightyears away perpetually focused on us at all times.

Point a gigantic planet sized telescope at it. done, you can now see Earth Live from 10 20 years ago.

If you looked at a mirror 10 light years away, you would see 20 years in the past

Siellus t1_j49afp2 wrote

Derp, You're right - I meant 5 lightyears away (roughly near proxima centauri, but went with 5 rather than 4.2 because meh) and 10 for the whole journey back and forth.

But you're right, I'll change it! :)

Willing_Definition71 t1_j4994vv wrote

I have heard similar ideas that if a time machine was created, that it would only be able to travel back to the point it was switched on

So since we have not invented it yet, nobody is travelling back this far

If wormholes exist, couldn’t we warp to a space far away from earth, look at it, then watch the light just reaching us?

Siellus t1_j49f02x wrote

Sure, You'd never find earth though. And you'd need a telescope the size of a planet at least, and even that probably won't be big enough.

>could we observe the past directly in some way

Yes. When we see something in deep space, light years away, we're observing that something's past, in real time.

If we look at a star that say, 100 light years away, we're watching that star as it existed 100 years ago. To see what's happening with that star at this moment in time, we'll have to wait 100 years, perhaps longer if that star is moving away from earth.

You mean the one that gets posted on reddit almost every day, "Think about what we'll know tomorrow"

Yeah, but Time travel is a whole different thing.

People keep regurgitating "yeah but we also didn't think people could fly" Yeah but we knew it was possible, Birds fly. Nothing in the universe travels through time.

Yes "That we know of", but inadvertently, if something like that is so hard to find, it might just give credit to just how outside of the realm of possibility it really is for gigantic, living creatures such as us to do it.

Science fiction and television have made the prospect seem so tangible, when in reality it's a lot like asking "Will we ever be able to shoot giant beams of energy out of our hands and destroy mountains like in Dragon Ball Z?"

The answer is no. Not just because "we don't know how to do it yet" but because it's literally impossible to the point where it doesn't make any sense at all.

Should we just stop trying? Lol no, That's not what I'm saying and that would be ridiculous, I'm saying it's not an active field of study, because the road to get to it either doesn't exist, or is so so so so unimaginably far out of reach, it may as well be impossible.

It's (conceptually) very easy to travel forward in time faster than normal.

Halorym t1_j493xj6 wrote

I buy the multiversal time travel theory. In which case kind of. You can travel to other realities like ours that progress at different rates so you can effectively view other times, but anything you do there won't affect ours.

In short term only. What most people know of time travel is based on Hollywood physics...

Time is a construct for the human mind. It's reality is based on how conscious you are, not how far you travel.

KjellRS t1_j498smh wrote

Even if it were possible, it's certainly not going to be like in the movies where you're in a mirror universe and 99% is the same. The world as it exist is the result of so many random events, throw things off even a little and somebody will wipe right instead of left on Tinder and meet someone else and everything diverges from there. If you go back with the intent to "fix" the past it's not going to happen, you're basically erasing your timeline and replacing it with something new.

Who is to say people already aren't? What makes you think you are special enough to be informed? Just like if ufos are actually humans, or maybe there are aliens visiting us and mankind has made contact with them. Evil rich bastard: "We gotta let everyone know bout this guys!" (Said no one). I like your whole fellow mankind "We" thinking but sorry to say it's not "We." dude.

DefectPicrews t1_j493mrn wrote

Technology has advanced incredibly quickly, however I don't think we're at a point where we can manipulate physics to our will within any of our lifetimes. The very fact that events such as the Holocaust haven't been prevented gives me reason to believe we will never find a means of time traveling into the past. You know what humanity is like, SOMEONE would have killed Hitler in his youth. There would likely also be very strict policies on who could use it and how it could be used so I doubt the general public would ever have access to it. Maybe time travel into the future could become a possibility though, assuming we don't wipe ourselves out anytime soon. ♡

Maybe, but they also could have potentially done it and discovered that it led to alternatives that were worse, right?

Perhaps the future is perfect and they don't want to risk changing anything even if it was an atrocity

Also we don't know what all these UAP sightings are, they could be observers from the future /s

A perfect future would be a dream come true, considering the current state of the world! However, I believe we're more inclined towards extinction to be honest. With great power comes great stupidity!

If you did something as drastic to the timeline such as killing Hitler, your boomer parents would never have been born and you would not exist. In fact almost no one younger than a certain age that exists today would be around. The world would be full of different people.

An event like WW2 directly or indirectly affected everyone on the planet. Prevent it from happening and your grandparents, if they meet at all, copulate at different times and in different circumstances. Even a slight change in timing and circumstances of conception can lead to a different soul being formed.

It's hard to imagine Marty McFly's mom getting knocked up at the exact same time, 3 times in a row, with a much more confident daddy McFly strutting around.

I hate parties.

battleop t1_j499ttv wrote

Einstein's theory of General Relativity says yes. If you can travel away from Earth at a fast enough rate then come back time would accelerate for you relative to the Earth. Not probably what you are thinking in terms of stepping into a time machine but about as close as you could get to it.

It's either impossible or, at least, we won't figure it out.

If it was possible then it would have already happened a near infinite number of times and we would be drowning in billions and billions of time travelers.

AdolescenceOfP1 t1_j49cwy5 wrote

Place "Time travel" as visited in science fiction on the back burner for a moment. There's a problem already.

So many of these comments throughout reddit are saying we are currently traveling forward in time, or that there is a travel forward that is "faster than normal".

What is, is. In the cases of things aging differently (from speed or gravity), there is no change in forward travel. The state at every time slice has dilated, nothing more.

mustafar0111 t1_j49d2uf wrote

I thought this was already proven as a yes to some degree with extreme mass objects bending spacetime. In the case of two blackholes bending spacetime so badly you could be in the future and present at the same time.

Its just not practically feasible for our civilization.

ive always thought about this. the existence of a connection between past and future is hard to prove in itself but, if we were to find a way....it would never be known to us. imagine telling the entire world that they could just zap right back or ahead to time.

New-Difference9684 t1_j49m0et wrote

Thought may be outside the bounds of time as time is commonly considered. In quantum dynamics, time may not even exist. In the macro universe, things follow Einsteinian physics or the block universe model with the concept of the arrow of time.

As much as I love the concept I agree with people here that time is a nontangible thing. It flows outward and away from our grasp.

Time travel to the future is easily possible. We don't have the ability yet, but will soon enough. However, there's no going back in time.

You can travel to the future by jumping in a space ship and going somewhere very, very fast. The closer to the speed of light you go, the faster thru time you will travel. Depending on how far and fast you go before returning to earth, is how much time will have passed here, compared to you.

A few months for you could be decades or centuries here on Earth.
