What Do You Think of Time Travel?

You make some good points.

I don't think it's semantics. I have always been fascinated by the concept of time travel, however there are many branches of physics that state it can't be possible. I have always felt though that there has to be more than what we know.

In the 100,000 years or so mankind has been around (and in the what... maybe 6,000 or so that mankind has had thoughts related to this sort of thing) that we know absolutely everything, and how the universe really works

I saw a kickass video to prove my point, it was about how space is an illusion.

So in theory, these two electrons react to stimuli, even if they are thousands of miles apart.. So, if this is in fact true, and can be proven, who is to say that we are 100% correct that time travel is not possible?

It might not be possible today, but then again, we also said 100 years ago that man would never go to the stars, set foot on the moon etc. (Unless of course you are of the belief that we never went to the moon of course, but that is another topic entirely lol)

 

it's not semantics, no. you could be right, give it another few thousands of years and who knows where physics is by then. my viewpoint on time travel being impossible stems from the simple fact that time doesn't really exist. future doesn't exist. and past doesn't exist. it's speed of progress. we have an illusion of time because of it. how can we go somewhere that doesn't exist? for time travel to ever become viable it would mean that the future already exists and that the past still exists too. and i don't think that is true. alternatively it would just mean skipping/manipulating speed of progress in part. that i see as a more realizable possibility. but that seems to constrict time travel in the direction of future only and it would have to come about as a result of manipulation of subject physiology rather than external space or 'time'.

i know that e.g. every single electron in this universe seems to know exactly what every other electron in the universe is doing. that sure seems weird and very alien to human experience, but i don't see how it's connected to the concept of time travel. this is all still happening in the present.

 

the electrons reacting to each other is quantum theory

do you think matter travels through time when it goes beyond the event horizon?

 

It didn't really have anything to do with time travel, just that it's an amazing science..

And if you are correct, and the past no longer exists, and the future doesn't exist as it has not happened yet, then the only way to "time travel" would be to travel at the speed of light, travel away for a bit and come back.. But then.. That by your standards really wouldn't be time travel, it would be more like signal delay.

I guess in order to really know if time travel is possible, we need to think of time as a tangible thing. if by using quantum mechanics we can prove that time is an actual PHYSICAL thing than for sure..

They say that if you got stuck on the event horizon of a black hole, time would freeze. this would only be true in that time was a physical thing being affected. A black hole is that which nothing can escape, not even light.. so even that would be considered signal delay for you.

The only way then that time travel could exist would be if you believe in the multiverse theory. That we are in a bubble surrounded by millions of other universes. In theory each of these universes would be going through the big bang etc, and going/developing at different paces.

Of course, you would need to find the EXACT universes with the EXACT same properties as the one we are in in an earlier state. and even then it really wouldn't be time travel, it would merely be sliding into the alternate universes. Where everything is the same, but it's at a different state of development is all.

I guess we won't know.. And unfortunately, unless they come up with the trick to immortality in the next 60 to 80 years... We're not going to know.

 

If time travel was possible how come we havent met anyone from the future.

 

That's because we aren't allowed to interact with you people from the past...



Wait!

 

Or at least when we do don't give a way where we are from!! Tyron you will be reported to the big giant head I'm afraid.

 

He is safe. You got his name wrong. :2thumbsup:

 

Just to ensure I don't start any prophecy or something

 

Well, time travel, if it's discovered and proven at all will probably be thrown away right away to not fall into the wrong hands...

All that stuff of paradoxes and the universe imploding etc.

Science says that if two particles cannot exist in the same place at the same time right? It's all about displacement, so if we went back in time, we would be materializing there and go "boom"?

Or of course, assuming it was perfectly safe, by even just observing the past, you are changing it... And who knows what sort of impact that can have a few thousand years down the line?

As an example:

Say you went back in time, and told Hitler to stop being an idiot and wait for warmer weather to invade Russia? We might all be speaking German right now...

Or:

Someone goes back in time and saves that Duke and WWI never happens... No war, good thing right? Well, there would be other things that would change drastically. There would be no more income tax as that was instituted as a temporary measure to raise funds for the war... uhmm.. OK, that's a good thing.. BUT... Penicillin might never have been discovered, because if I am not mistaken it was discovered by accident during the first world war by a doctor in the field.

So you see... Even small changes, or big changes, could have a huge impact on our history.. it would need to be monitored in a way that would never be possible.

So... The thing is.. Even if it were possible, it would be way way too dangerous to ever let the public know about.

Still cool to talk about though

 

you've perfectly understood my viewpoint on all this. now you see why i don't think any of the above can be considered time travel.

the last thing this planet needs is immortal human beings running around on it (and i'm not even an environmentalist). and aside from the fact that i don't think time travel is physically possible, i also hope things will never progress to a state where it does become a possibility. all the human experience, our life, it would become completely meaningless.

 

I agree with you on the immortality stance, everything has a cycle, and as much as I don't like the idea myself, a cycle needs to have a beginning middle and end...

Why do you think it would mean our experience, and our lives would be meaningless if time travel were possible?

Are you looking at it from the angle that if someone makes a mistake or something that they would just immediately go back and fix it? Or are you looking at it from another angle?

 

I'd never thought about that.
I imagine if you were able to factor in a geostationary time differential synchronisation equation and then put: 'Geostationary Orbit Determination' on the side of a rather shiny flashing box - in theory you might be able to compensate for the shift in position. Doesn't everything in the universe do that anyway, or else we - for instance - would not be in one piece.

I like the idea of 'folding space'
I like the idea of time being like tangled string.

 

"and I'm not even an environmentalist". Good thing you don't live in an environment then. That would be bothersome..






Time travel is an interesting writers device,but is a fantasy,perhaps like reincarnation-IMO.

 

alright to all here: yes time travel is real but in a different sense.

for instance due to the theory of relativity: lets say you travel 25 light years away at near light speed. then you travel back to earth at near light speed. you would've aged 50 years maybe 51 (gotta hang out w/ the aliens right lol) WHEN YOU GET BACK, earth would've aged 4 1/2 MILLION years.
i read that in a science book. yes i can give more examples of strangeness like this too

 

Time is only linear to us. If we were a hyperdimensional being we could see time as something like a "sphere", you could see all time past present and future, and alternate times (left and right). Its like a video tape, you play the movie from front to back, but all of the information is all on the tape all at once.

If you watch "Into the worm hole" on the science channel they always talk about time travel and worm holes. Our math and physics do allow for time travel! Its science fiction without the fiction!

Now they usually say the technology isnt really here, but according to this video it seems like it is. As far as wormholes, the technology and energy needed is not quite there yet.

Now there is another field of time travel that we could do right now if the right discipline is applied. Yoga has been looking into this for millenia, but now logical scientist and physicist have studied this and proved this. The information is hard to find but its there.

A great book is "My Big Toe", which stands for My Big Theory of Everything. It explains how you as an individual consciousness can step out of this reality frame and be able to travel in other worlds, other dimensions, and other times. You don't need a time machine, only your consciousness and a meditation process. Basically an out of body experience can be used to do this.

You can see the past, and you can see the future in probability vectors. You can see all the possible future states that can happen and plan your life accordingly. You can use your consciousness outside your body, and travel through all sorts of different planes of reality. This physical reality sits inside a larger "nonphysical" reality. If you expand yourself, and drop out of this reality and into the higher reality, you can experience a much broader view of our reality.

 

^personally im not so sure about the yoga thing myself^

here's another thing to think about: lets you are sitting in one spot in space. i start to move towards a black hole. as i get closer and closer it apears like it's taking longer and longer. i start moving faster and faster, and yes reach almost light speed. to you at the moment of the event horizon, i am moving so fast, and time is being distorted so much for me, that TO YOU, i will STOP! and redshift till i disapear, and it will take A LONG time for me to disapear. remember:
as you get closer to the event horizon, it takes more and more velocity to leave it's gravitional grip. after the event horizon light cannot escape either. so just before the event horizon light is moving towards you, but so slowly it appears i stop.
plus due to the velocity of how fast i am moving towards the center, time is also different for me than you as well.
but time is relative. neither of us will truly notice it. to me, i just get crushed. to you, i stop and freeze in time.

 

How old would I be if I stepped sideways into 1449 and then back again? Not "future" not "past" but sideways... How old would the earth be? What would happen if I left my cigarette lighter there?

 

i dont know lol

 

Yeah... they never talk about that in those school books... :rofl:
