[QUOTE="nintendo-boy"][QUOTE="sandroDX"]nice logic, BUT, time travel can exist (if we ever find how to do it), but as far as i know it would only be possible to go back in time, since the past has already happened... and unless the future is pre-determined, we cant travel to the future... this time travel stuff is very confusing, yet it is very worthy of discuss..xaos
Actually this sorta makes sense. If this is true though, wouldn't that mean that once you go back, you can't go forward again? I mean, even though YOU know the future, it technically hasn't happened yet were you are, so unless the future IS predetermined, it would be a big sacrifice to go back in time, and therefore whats the point?
Whereas in the lab, time travel into the future has been done, as mentioned above, and the laws of thermodynamics and general and special relativity say that we can't go backwards in time.Well then that means ther IS a predetermined future. Thats kinda cool.
It might be a bit difficult concept to wrap your head around but time does not exist. Time is a measurement invented by humans just like meters, and kilometers. So therefore time travel simply cannot exist.serb1030
One other thing...you're confusing what we're measuring with the fabricated unit of measurement. So where you say time, you should also say distance. And where you say metres and kilometres, you should also say seconds and minutes. See the difference?

Not at all; it doesn't "skip" the intervening time and ignore causality, but just moves more "quickly" through time while moving at a higher velocity. It would see things at relative rest looking like they were being fast-forwarded, but events would still proceed in accordance with physical laws. There *is* a predetermined range of future possibility, according to relativity, as defined by the light cone diagram someone posted previously in this thread.Yah, there HAS to be some sort of time in the universe, I mean, everything didn't just happen at once. Humans were put on earth AFTER it was created, you eat dinner AFTER lunch, you die AFTER your born, and so on. I mean, the only way for there to not be some sequence of events in the universe would be if nothing ever happened. The only way for there to be no kind of time would be if the moon NEVER revolved around the earth, the trees NEVER grew, and so on.nintendo-boy
Time most certainly DOES exist.:|
Time, in the way you are speaking, does not exist.
But Time, as is the way it is presented in physics, has another term. Cause and effect. And this most certainly does exist, therefore time also exists.
As for time travel, I have no idea.
If you think about it
Time and Distance measures have certain qualities
Let's say you travel 10km in an hour.
Now if you walk back to where you started,
you don't go back to 0km and 0 hourts, rather 20km and 2 hours.
Although, you can go back to the 0km/0hr mark.
It's like watching a movie. You watch an hour of it, then rewind it. The movie time scale is at 0h, but you're time scale is still at 1h.
Another example;
You and your friend walk the same distance in an hour. Your friend walks twice the speed as you. After an hour, your friend has reached the goal of 1km, and you are still at .5km. Although you are on different time scales in the measure of how long it takes to get to the goal, your overall time measurement is still the same, for he has to wait for you to reach him.
What I'm saying is, time has different measuring purposes for individual purposes, but also has a bind over everyone and everything... but it's impossible to go back physically, for it doesn't physically exist.
*also noted, it's the only dimension in which you can only travel one way... so technically, it shouldn't be a dimension. X Y and Z dimensions, you can traverse any way you please...
That's like saying length, width and height don't exist because humans came up with symbols and names to represent it.
Time does exist. Humans just came up with terms to represent time, such as minutes, hours, days, weeks, etc.
Exactly, a banana is still a food, even though someone came up with the name. Well...Uh.... The TC should just give up speaking or any form of communication, since nothing exists. Such as TVs, they're not real, because that's just a name they were given, so they're not real.....I guess.That's like saying length, width and height don't exist because humans came up with symbols and names to represent it.

so everything in the universe happens simultaneously.... The measurementis invented by manbut even cavemen understood that at different times different things happened
It might be a bit difficult concept to wrap your head around but time does not exist. Time is a measurement invented by humans just like meters, and kilometers. So therefore time travel simply cannot exist.serb1030
No, that's silly. HOW we measure time is certainly a human construct, but objects would change position regardless of if we had any concept of time.
Movement proves that time exists. Unless everything is everywhere simultaneously (not true), and unless everything is forever stationary (also not true), then the act of motion requires that something be HERE at one time and THERE at another time.
As in, if an Object is at Point A and then moves to Point B, we have to consider what happens at Point A.
So we can take the coordinates of Point A. If motion is impossible, then the presence of an object at Point A should ALWAYS be a property of Point A. If that object is EVER absent from Point A, and Point A's physical location has remained the same (if it were to move, then that would again be an example of motion, which would prove the existence of time), then the only difference between the location of Point A with the object andthe location of Point A without the object isthat object's position in TIME.

discovered by humans. not invented. therefore time travel exists.

Umm, you have a valid thesis, but your conclusion is completely unsupported, unless you are referring to known stuff like time dilation.Well, I think the majority of the physicists around the world agree that time does exist. So I think it is really silly to come to Gamespo'ts forum to prove that for some reason you are right the the majority of the scientists around the world is wrong. This happen before, when a single individual come along to prove the world wrong, but your statement is neither ground breaking nor oriignal, so I think you simply need to read more materials about time and do a lot more research on the matter, instead of coming up with a semi-petaphisical statement that partially makes sense to yourself. Sorry if it sounds mean.
If time is only a concept not an actual thing, then the effect of time on any individual should remain the same under any circumstances. But it has been observed that, as object travel faster, the effect of time slows down for this object. The famous example would be the Twin Paradox, which explains how a pair of twins, for which one travel at near the speed of light to a distant place in spaceand one remain on Earth. Many years later when the space-travel brother return to Earth, he will find that his twin brother is significantly older. This is because time slow down for the brother that traveled at extremely fast speed.
But when it comes to time travel... well, I'm quite confused about how this is ever going to work. So, the latest theory suggest that we cannot go back further than the time we invent the time machine or something along that line. but, supposedly we do invent a time travel device..., wouldn't it be really weird to see the result of the mission before it even begins? I mean, i is that even logical? To see yourself sitting in the control room, saying "good-luck" to your time-travel mission, and knowing it is going to work because you are looking at the result of the mission right now!
and, does that mean if you don't see yourself visiting you 5 minutes before the mission start, the mission is definitely going to be a failure because if it would succeed, you should see the result already?
I'm so confused.
This guy mentions"meters" and "kilometers" yes, those are only measurements, but they measure something. So if you say "time" is a measurement then it measures SOMETHING. If we can travel by meters and kilometers, we can travel in time.
But then again, "time" really a measurement. "Hours" and "minutes" are. time is more like "distance." And we can travel distance; so therfore we can travel time.
Aye, but it is--as most things are--are a matter of perspective. Time travel seems to me to be thoroughly impossible. Time is change. Everything is changing constantly. As you move faster, the rate of change slows down. But to describe like this is to describe as something that is not definite. To provide this kind of description, imagine every moment as an eternity in itself and then imagine the smallest, most miniscule amount of time to pass and you have another universe. Then how do you jump between these points? A wormhole is the only way, and that is fairly sketchy.This guy mentions"meters" and "kilometers" yes, those are only measurements, but they measure something.

Time is indeed a concept like the concept of zero but it does exsist. there are four stages of time
1.Planck time the short time before the big bang
2. big bang and creation of the universe
3. the decay of the univers in which everything decays
4. just photons flying around forever.
also the concept of time travel is also very impossible due to the number of paradoxes created by the same matter having already been created still being there and as we all know matter can't be created or destroyed and during time travel you are basically creating matter.Now there are diffrences in the types of travel such as interdimensional or para-universal where you think you go back in time but you actually travel to another universe where you haven't been born. You can also think of time travel as being just your time and by that it's where you just go back to your body to another time you were alive in while still keeping your conscience there so if you went ahead twenty years your body would age twenty years but your minds perception would be from twenty years back.So time exsist just not conventional time travel.
Thank you science chanel and my physics teachers!

lol...i wonder what the TC is thinking after being owned countless times in this thread.Aznsilvrboy
Yeah, I figured by now, he probably doesn't think that posting this was such a good idea...
[QUOTE="DeeJayInphinity"]Actually, we can, going forward. Time dilation FTW. Of course, you'd have to go 99.999992283950617283950617283951% of lightspeed to get the Lorentz factor you are describing (1 hour/1 second at relative rest), as defined by the Lorentz time dilation equation: I fail to understand, are you saying that, if it took me 1 hour to travel from point A to point B going at my speed, going at 99.999992283950617283950617283951% of lightspeed i could get from A to B in 1 second? i agree with this however, what i'm trying to say is you arn't skipping a whole hour, you are just saving yourself time so that it doesn't take an hour to get there.[QUOTE="Yongying"][QUOTE="xaos"][QUOTE="Yongying"]Traveling to the past or into the future is something we will never do. Traveling at the speed of light we might one day but we cannot physically skip 1 hour of time in 1 second.Yongying
No, you're not saving time, you're slowing time down. Everyone else who just watched you travel the distance thought it took you 1 hour, but it actually took you 1 second. It's relative.
You yourself did not age for 1 hour, nor did you see the hour pass by, you only aged 1 second and you only saw 1 second go by, but everyone else aged for 1 hour and saw that hour go by.
Very much like if I were to travel to another galaxy in 5 years near the speed of light. Upon my return to Earth, it wouldn't be 5 years later, it would be thousands of years later. I don't want to do the whole equation, you can if you want to, but you will see that I technicaly went into the future.
If i believed in that then i'd have to believe in god also. I understand what you are saying but it seems waaay too magical and spiritual and stuff for that to be possible.not magic man. its science. this is nothing involving religion or magic. straight science. yes technically through this process "travel" into the future. but time is relative. so it will only seem that way. just as everytime you look at the night sky you are looking VERY far into the past. it takes the light hundreds of thousands of years to get here. so effectivly we are seeing things that have not been for thousands of years. looking at that one star you are seeing as it has been way way long ago. not as it is today
It might be a bit difficult concept to wrap your head around but time does not exist. Time is a measurement invented by humans just like meters, and kilometers. So therefore time travel simply cannot exist.serb1030
What your syaing doesn't make sense. Just because we measure in meters and feet doesn't mean distance doesn't exist.
So you're saying that distance doesn't exist? Damn, I've been using my car for no reason. :roll: I honestly hope that this is a joke thread, saying time doesn't exist throws out half of physics.
Time is a dimention, just like length, width and height are demensions, we as humans have the capability to quantify them, that does not mean that they do not exist.
