Hey, I was wondering, is time travel possible? Thanks a bunch!

I wish it was possible and practical. I would be using it.
To answer your question nobody knows for sure because it has never been done as far as we know. It is an abstract theory.

I believe that one day time travel will be possible. The Elegant Universe and Parallel Worlds are both interesting reads that encompass this subject.

There is a guy who took Einsteins theory of relativity and is starting to build his own little 'thing'. The idea is if you take light, and make a vortex (tornado tunnel) of light, nothing can escape the light. So you send a beam of present time (as light) into this tunnel, and it would forever sit there and never escape, thus in the future you can look into the past (or future) with this tunnel.

Youtube video:

If it was possible it will be invented at some point in the future. Maybe a hundred years from now, maybe a thousand or even ten million.

In that case, why have we not had any time travellers come back to us yet?

(Cue the folks saying that UFO's, demons [LOL!], spirit manefestations etc. are the time travellers)

this is something i wonder about

http://www.unexplained-mysteries.com/forum...howtopic=112729

i've got some kind of theory on the matter in that link above.. tell me your thoughts?

I GOT IT!!

We are all time travelers.. You know how?

After I typed the last letter of what you are reading, 1 second has gone by, thus making you the length of this sentence (x) number of seconds in the future from the first letter of this sentence!

that's really scraping the bottom of the barrel

if time travel is possible? I think yes, but not now...maybe in a distant future.
Why we dont see time travellers? well perhaps they avoid all the time travel paradoxes by exactly not revealing them self to the pubblik.
But on the other hand how do we know exactly the timetravellers dont operate 8silently) in our dimension? perhaps is thank to them that people like Hitler and mussolini have lost the war? who know's...

^ nice theory.
who knows, that may be possible

i dunno

i say no
yet yes

if you traveled back in time you may actually have gone to a dimension that runs a little late.

would this be time travel?

the laws of physics acuity support the ideas of time travel

Tipler cylinder as such, Ronald mallet, even different time zones in other areas of the universe.

I wish it was possible.. i would like to try it.

It may happen in the future lol
Maybe a few hundred years too
xD

Myabe! It's possible I would like to be the first to try it

Crono-Phasing may be possible

if i check up on the physics of my theory.

actually my phasing tech[ideas] makes anything possible.
thats why i abandoned the theories.

too much power for the children [humans] to play with.

Yes it is possible. We know that gravity and fast speeds distort time, so if you travel really fast or go into a strong gravitational field, you will age slower than other people. The only problem is that we don't have the means to go fast enough to really tell a difference. The best thing to do now if you want to time travel is go into a space shuttle and orbit earth. At that speed, you will be 1 second younger than if you were on earth. It's not much of a difference but i guess it's a type of time travel.

Regarding why no one has gone into the past: Basically, the laws of physics do not permit this. Going into the past is purely hypothetical and was derived from a hypothetical model of the universe.

Yes, you could go back, however I believe it would displace yourself. You can go to the future however it would be a false future (because it would be without your presence). Quite possible there are TT's living with us today, however this is up to probability... are we living a displaced timeline of a displaced traveler? Akin to the John Titor story, I believe JT could be a time traveler, however his mission (go back to the 70's to retrieve old computer and return it to the future) has failed as he has interfered with the timeline... he may have returned to his own time, only to find out the war never happened.

We can't see the 4th dimension. What if time travel is used in that dimension?


Time travel is getting from point a to point b before the light from point a reaches b. You will see the present ( what is past at (a). Now, in the 4th dimension, we can demonstrate it, but we can't see it. Since it's so complex for our minds not to be able to see it, there must be a change of how light travels or bounces off.

I thought I read somewhere a long time ago that nasa proved you could travel forward in time. They synchronized thier clocks before a space flight and the guy came back with his clock reading something like .03 seconds faster then what they were on the ground. So he essentially went .03 seconds into the future. I don't recall the whole story.

As far as travelling backwards in time I think its impossible.

IMO when we learn how to travel sideways in time we'll probably know where all of these so called flying saucers come from. I don't think there is a 4th dimension or a parallel universe, I think its something else having to do with time travel.
I also think this is probably what they work on in area 51 and the hill air force range. Think about it for a minute. If you could go "sideways" in time and travel to a spot you want to go then come back,your trip would be totally invisible (because your not there) and your arrival would be a complete suprise. We all know about the what the element of suprise means to an attack.

But then again, What do I know...I'm just a welder.

Yup, time travel is not only possible, but quite unavoidable. I predict that right now you are travelling through time at the rate of 1 second per second. Grab a clock and tell me if Im right.

For those of you with a lay-mans grasp of relativity (like me!) http://casa.colorado.edu/~ajsh/home.html is fantastic. Try to get your head around the 4D rotating hypercube! I have stared and stared at it, but I just can't internalize it. Stuff like this should be taught from the age of 2.....

Time travel is possible according to Relativity. According to Relativity (and I'm sure Pawna will correct me if I'm wrong), the faster an object travels, the more time will distort and begin to slow down as it nears the speed of light. Hence, once you break the speed of light threshold, you would be traveling backwards in time. However, Einstein says that nothing can travel faster than the speed of light. This is because the faster an object travels, the more mass it gains and the heavier it becomes. The heavier it becomes, the more it will begin to slow down. For something to travel at, or faster than, the speed of light, it would need infinite thrust (because the gain in mass would also be infinite), which is impossible.
So how do we measure the affect of speed on time? Well, it's relative to the point of view of the individual.
Imagine two people, Bill and Bob. Bill will be traveling close to the speed of light and Bob will be observing. Bill has a bouncy ball that he can position above the ground so that, when he drops it, it takes precisely 0.5 seconds to fall to the ground and 0.5 seconds to bounce back up to his hand. When he is stationary, Bill drops the ball and catches it again. To both Bill and Bob, the ball has traveled in a straight line and took exactly one second to fall and bounce back up to his hand. Then Bill sets off and, at 100MPH, drops the ball again. From Bill's perspective, the ball falls and bounces up in a straight line again while, to Bob, there is a slight v in the ball's trajectory. Now Bill is traveling at close to the speed of light and drops the ball again. From his perspective, the ball again drops and bounces up in a straight line. However, from Bob's perspective, the V shape of the ball's trajectory would not only stretch the length of your computer screen but probably from one side of the room you are in to the other.
In other words, from Bob's perspective, the one second it takes for the ball to fall to the ground and bounce back up again has stretched and is now taking much longer to travel its course. Yet it still takes the same amount of time for Bill. Therefore, from Bob's perspective, Bill is traveling much slower through time than he is (yes, I know that if Bill was traveling close to the speed of light then Bob wouldn't be able to see him at all. This is just a demonstration, so use your imagination people). That's how it works in Relativity. So, if you 'could' breach the speed of light, then you would be traveling backwards through time. However, Relativity doesn't explain how you would get back to your own time again.

Hi Seffy

Just two little things (Im absolutely no expert) mass and weight are not synonymous (ie on the moon your mass would be the same but your weight would not - you would be lighter standing on scales on the moon than you would be on identical scales on Earth). And if you were in space (where else are you going to be travelling at the velocities required to notice these effects) which is a vacuum, I dont think you would slow down as you become more massive. From what I remember, its that you need more energy to accelerate the mass you have already gained...

And I think this is because mass and energy are the same thing, the faster you travel (requiring more energy) the more massive you become.

These discoveries are vitally important. If Im wrong about anything here please someone correct me, as its important to get it right.... As I said, I think these things should be taught in school. Kids pick up these mind-bending concepts much quicker than adults.

Pawna

Of course, what a stupid oversight. What does weight matter in a weight-less environment? It's glaringly obvious and I still missed it.

Wow, you sound like Patrick Troughton's Doctor. Ooooor maybe Sylvester. Not a huge fan of the new series mind.

As a huge Doctor Who fan, I can't help feeling very happy with that compliment. Thank you.

> What Does that mean?
?


Supposedly if you travel at the speed of light you can slow or speed up time (but not go back). If you go fast enough you will go far into the future. But nobody wants to leave our time period forever, besides, there is no way to prove that it works, because everyone would forget and think the Time-Traveler was (is) insane.

Would that be past or present tense? Time travel talk always gets me on these points...

They are being learned in the school I am at... It's taught in 7th, 8th, and 9th grade at least...

Introductory Physical Sciences (9th) is an optional class, but then, not everyone is a gardener or a farmer (Not I, I hate farmwork.).

Hey new guy here, I am by no means an expert on the subject but I do believe that as you accelerate time slows (and eventually stops as you reach the speed of light.) Now if you could somehow accelerate to faster than the speed of light, time would flow in reverse. This obviously can't happen because matter will break down at the speed of light according to Einstein.

The question has been asked if time travel does exist in the future then why have we not seen any time travelers? The answer is simply because you can only travel back to when the first time travel occured. You can't travel back before a time machine was invented. This is why it would not be good to be the inventor of the first time machine because you would only be able to travel back to the first time you turned it on.

This is not really true based on my knowledge. The only reason someone can't go back in time is because relativity does not allow it. The only model that allows time travel to the past is based on a hypothetical model of the universe.

But someone can go back in time (theoretically) BECAUSE of relativity.

What hypothetical model of the universe are you referring to?

I was referring to the Godel universe which is derived from the equations of relativity. Though it is an interesting model, many people ignore it for some reason.

Hmm, well my take on it is yes. I added this theory of mine in the big bang topic. If you take spirituality and science and combine it, you get something interesting. Take the emerald tablet quote "As above, so below" Now take a look at quantum physics where everything behaves so strangely. Well were just looking at the bigger picture. Time is just a product of our "energy level" for example if you take the notion that the closer to the speed of light you get, the more there is a distortion in time. Well we on a higher level then then quanta see it's world as instances that don't quite make sense because our perception of time is different from "theirs". Now if you go back to spirituality again...and hear about the beings and psychic stuff, it's all on a higher level. WE become the quantum world and they are able to tell us "in a sense" what will happen to us because they already see those possibilities happening. They are above our time. Time is relative to the observer but it's the amount of energy they have that determines the perception of time.

Well that's my 2 cents at least. Blessed be everyone!

No they cant, not because of the theory of relativity. Perhaps you should learn about the theory of relativity first before making such claims.

There's a certain balance in the universe I think. By removing yourself from one reality and adding yourself to another the balance would be effected. If you could travel between realities with your mind you wouldn't be aware of it anyway because your mind is supplied by information from your brain. As far as you know you would have always been in that reality. (One you travelled to)

who cares if it is or its not? what purpose would it serve? if you went back in time to stop a murder, or make some investments, and then hop into a machine to the present day...what memories would you have? would your mind just create some out nothing? as far as time travel goes im more concerned with the effect it would have on my own sanity more than being a fly on the wall at the roswell site.

Tbh I think we're already effecting the outcome of probability. Just in not as direct a form as time travel. Look up on some books like "The Secret" and "Think and grow rich" the prospects are fairly amazing however I think maybe a bit over exagurated.

has "The Secret" even been proven to work?

Well, you don't hear about the failure rates so I can't say that I'm certain. However I can tell you first hand that really wanting something can produce some surprising effects. Just try it for yourself. Imagine you really really want something, imagine it in your pocession and wait. Be insightful though, it might come to you in a different way than you think. The best way to prove/disprove something is to simply try yourself. By the way, for a bit of a laugh check this out, its pretty funny http://youtube.com/watch?v=Et_jG58qg1k

PS. I think the way "The Secret" was illuminated is a bit extreme, but I'm not completely ruling it out.

Oh, by the way, I would probably recommend "Think and Grow Rich" over "The Secret." I feel that the idea in "The Secret" was stolen from Napoleon Hill who dedicated his life to understanding why the successful are successful. He's one of the earliest producers of the book of personal success (Think and Grow Rich).

try telling that to millions of fanboy virgins praying to get laid everynight!

Ahaha lol well put. Result cannot be reaped without action however . I'm thinking about starting a whole new topic on how I think the "Desire and receive" prospect works. *Sigh* that's going to be a big type, good thing I can type 160wpm lol.
