Here is a question to think about.
 
If you went out in space and was traveling at the velocity that is greater or the same as the speed of light do you think time would stop?

lx_theo June 4th, 2010 1:52 PM

More the opposite, actually. You would, in a manner of speaking, go forward in time, going faster than time itself.

Binary June 4th, 2010 1:54 PM

Ah..no, I don't think time would stop.
Else, the light from the Sun would reach the Earth without having to travel the few minutes. Or am I wrong?

AaronOnPokemon June 4th, 2010 1:54 PM

Actually everything else will stay the same by stopping you will be going forwards. But you wont be going forward in time because nothing will happen because of everything is the same.

Tacogeddon June 4th, 2010 2:05 PM

Traveling greater than the speed of light is impossible, as far as we understand anyway, hyperdrive this, warp speed that. Someone's watch on Alpha Centauri is going to end up different than someone's watch on Sol even if they could be set exactly the same, because even though the speed of light is great, it still takes time for it to travel across the sheer huge-oscity of space. Your time is relative to you, not necessarily someone else. So if you travel at light speed, you'll find that your watch appears slow to the watch of someone where you arrive.

So I guess relative to you, time is slower.

^^ This would happen.

Also, this is what some scientists believe could pose as time travel. They say that if one traveled at light speed for some distance then traveled back to earth, they would find themselves in the "future." It'd be a one-way trip, however, as there is no way to go back. Unless, of course, in the future, somehow, somebody figured out time travel...XD

JakeyBoy June 4th, 2010 3:28 PM

I was told once that it was tested and proven that as an object approaches light speed, the object notices time slowing down. I don't fully understand it, but the people above are probably correct. Though I don't think you could call it time travel.

Or, in a more obvious manner, v=d/t, so t is inversely proportional to v, so as v increases, t decreases. I think I just gained a higher understanding of the theory. :D

Mattysaurus June 4th, 2010 4:09 PM

I don't know, but I was watching something on the History channel that was talking about black holes and how when you reach the center of it, everything out side looks to be slower. But that's probably because you are being sucked in faster than the speed of light, right?

Jack June 4th, 2010 4:14 PM

If you travel faster than light, everything is like as slow as a turtle to you because your going at such a speed. [ Dont understand but whatever ]

The event horizon of a black hole has an escape velocity that is mathematically greater than the speed of light, but since it's impossible for something to BE faster than the speed of light, you're going nowhere surprisingly fast. :P

hiphiphippo June 4th, 2010 5:24 PM

i think that would be cool - traveling at the speed of light with everything slowing down
but i think you might just like rip a hole in the universe and create a black hole of doom o:

twocows June 4th, 2010 5:24 PM

Everything in physics must have a frame of reference. If you consider the frame of reference of light, if I start moving the direction the light is coming from, I'm already moving faster than the speed of light. I think that's heavily related to how things behave at those speeds.

PokeWe June 4th, 2010 5:48 PM

A theory that I consider, is that time doesn't exist. So in my opinion, being a mere concept, time wouldn't necessarily stop.

Well done!

You're right... as far as we know, time doesn't increase when we travel at faster velocities, but actually decreases (relative to the traveler), and I believe it has been proven. Mu mesons are one of the more interesting examples: little particles that continually travel down from the sky at something like 0.8c, and while to us they survive for a a fraction of a second, to them they survive for much longer, and even see a distortion (length contraction) in the environment.

Interesting stuff!

Dawn June 4th, 2010 6:24 PM

I just imagined someone going so fast around the world that they manage to step on the back of their own foot and trip themselves. (Yes, I realize that's impossible.)

I lol'd, though.

Somehow I doubt time would stop. Then again, I have NO idea what I'm talking about here.

I dunno?? ¯\(°_o)/¯ Has anyone experienced hyperdrive, teleportation and warp stuff??

LethalTexture June 5th, 2010 2:31 AM

I believe it is accepted that an object travelling at or close to the speed of light would experience time at a much slower rate that in actuality. For example, if you are travelling towards a planet at or close to the speed of light, mere seconds would have passed for you, but on the planet five years will have passed.

  • Wormholes
  • Tachyons
  • Alcubierre Metric
Are all examples of faster than light travel that are absolutely possible.

Zet June 5th, 2010 2:49 AM

I don't think time slows down at all when traveling at the speed of light. I think people just perceive things being slower than they really are. It's like doing 300km/h in a car and you go past a car traveling at 100km/h, and don't know it.

Alkaide June 5th, 2010 6:23 AM

As fast as lightning, OMG.

I think that I would have died before thinkin' 'bout that, but I think no, the time would not had stopped~

KejiBebi June 5th, 2010 8:43 AM

I don't think its possible for time to actually ever stop moving forward.
I'm not saying its not possible, I just don't see how it would be. :o

SIN1488 June 5th, 2010 9:58 AM

I don't know enough about that stuff yet to say for sure, but I'm guessing no.

So here's another question. Let's say you're floating out in space, only moving in one direction. Is it possible to reverse your momentum and only go in the opposite direction, just using your body?

Cloche June 5th, 2010 11:12 AM

Have you seen 2001: Space Odyssey? It would be a trip like none other.
But, in all seriousness, either you'd create some black hole, or go forward. I dunno... I haven't seen "cosmos" in ages, but it is a very interesting question, that someday, I'd like to find the real answer to.

AaronOnPokemon June 5th, 2010 2:41 PM

My theory is that if you are traveling greater than the speed of light you will not stop or start. Everything will stay the same for everyone, but the person or people that are traveling faster.

Lets say this, you have a person that is the same age as you. You where born at the same time, same date, same place etc. If you are going faster than the speed of light I think you would get older than that person. This is only because is you traveling at those speeds you will have to take in fourth dimensions. This will mean that the whole concept of time will be in the balance. So if you traveling at the speed you will create a time elapse causing you to make everything, for you, stop.

But I think this may happen :-

Time travel
 
So everyone know what is time travel. Maybe some of you might know a physicist called Michio Kaku. I watched one of his video and he say having a spaceship that can travel in a very fast speed, it can slow down time. I don't really understand...one of his example is you travel in that spaceship far from Earth for 10 years, when you get back to Earth, it pasted 70 years. I want to know what you guys think and if you know more about it, welcome to post in here. :)

wakachamo June 5th, 2010 5:52 PM

Essentially this has to do with a law of physics - nothing can go faster than the speed of light. With this, it is assumed that nature has a few safeguards for this.

Imagine you have a train that is traveling at almost the speed of light. Very close to it. If you were inside that train, and were to run inside it, you would theoretically be running faster than the speed of light. (The train's speed + your running speed would surpass the speed of light) However, because nothing can travel faster than the speed of light, 'nature' stops you from doing so by slowing down time for you. Therefore, you would be going so slow you would not be able to reach the speed of light.

Since time is being slowed down for you, everything around you is 'speeding up'. 5 minutes of your time could be 1 hour 'outside'.

And thus the idea of easily traveling into the future is born - you just need something really, really fast.

This isn't really 'time travel' though - this is more along the concept of keeping yourself in a time capsule; preserving your state and letting time flow around you.

Zet June 5th, 2010 5:54 PM

Wouldn't be so great if you did that and found the Earth to be destroyed only a few years later.

There's a bigger problem for time travel than traveling faster than the speed of light. It's the fact that everything in the universe is constantly moving.

Due to the fact that the Earth is moving around the Sun and the Sun is moving in the Milky Way Galaxy and the Milky Way Galaxy is speeding through space... If you went just one second into the future, you'd be lucky if you were near Pluto.

So a destroyed Earth would be the least of your worries...

NarutoActor June 5th, 2010 6:30 PM

Who cares, if you can travel faster than light you should enter a benefits marathon.

I'd think that the fact that going backwards is still theoretically impossible (For all I know, at least).

stonehearteddd June 5th, 2010 7:26 PM

Honestly, who would want to travel into the future, anyway? I wouldn't.

Ayselipera June 5th, 2010 9:33 PM

No traveling into the future for me. I think the world just keeps getting more boring year by year. A 70 year jump into extreme boredom would be torture. I rather go back to the past where I could just do my own thing. 1800's "wild west" America would be the most preferable.

Overall I really don't understand the theory of time travel. I have trouble viewing time as a thing that you can forward and reverse. I don't even view time as a thing. It's just a way to describe the passing of days and such.

Serene Grace June 6th, 2010 2:39 AM

You would die. Or go forward in time.

Volroc June 6th, 2010 3:33 AM

id change a few events in the past, kill a few people i shouldve, save a friend i let die, stop myself from doin the 3 worst mistakes...

time travel is a blessin& a curse. no one should wield such power.

That's not the way that time travel would, at least in theory, work. The basic principal of time travel is not blinking out of existence in your own time only to re-appear at the exact same spot at a certain time in the future, but instead have your own personal realization of time slow down. The fact remains that you will not suddenly lose gravitational pull towards the Earth just because you are time travelling.

Think of the time stream as a river. If you are in a canoe on said river, and you begin to paddle, you will go faster than the normal current of the river. If the river winds and does not follow a linear path, this does not mean that you are going to suddenly end up in a tree a kilometre away.

Ninja Caterpie June 6th, 2010 4:31 AM

At the rate we know science, we can't make time "speed up", only "slow down" to us, so we can technically only go into the "future".

The thing about going "into the future" is that you need a means to get there. As I said before, it's not like you blink out of existence and then re-appear in the future. You have to go through the time stream at whatever pace.

PokeWe June 6th, 2010 5:09 AM

I strongly believe in the theory that time doesn't exist. Theoretically, time is a concept used to measure lengths of time, created by us. Take away the concept and you just have one continuous span of events all taking place in the same moment. It sounds weird, but I have come to believe it. Therefore, with no time, traveling it would be impossible.

AuraGaurdian June 6th, 2010 7:48 AM

while a very other worldly concept to us it could still happen.
so what we are saying here is that nature itself is preventing us from breaking the speed of light by slowing down the time around our physical being and we can use this to our advantage by using this effect to travel through time because as we are slowed down, time around us would continue to move at its normal; speed so while we would feel no different we would actually be going alot slower than normal so technically looking through our own eyes everything would look like u hit the fast forward button on a movie until we stopped going the speed we are going so to explain it using Fujitsus theory we are canoeing down the river of time and we suddenly start going faster than the river itself and then to stop this the river forces us to paddle backwards so that the current still takes us but we go dramaticaly slower and in this way the river (time) still flows at its normal pace but we go slower
and since the river (time) is going at a quicker pace than us much of the river (time goes past us (Ill let u guys finish this theory out) so if alot of time passes us out then well be........

Jolene June 6th, 2010 7:54 AM

Most people think that time is like a straight line, but I think that time is more like a big ball full of time stuff. The people who write time travel stories all seem to think that you have to hop from one point on the straight line to another if you are travelling through time, but what you must really do is roll the time ball.

That's got to be some sort of world record for 'longest sentence'. Thanks for basically repeating everything that's been said so far in this thread.

Heart's Soul June 6th, 2010 11:18 AM

You do know that "time" is something that man created to name existence? Time doesn't really exist and we can't explain how can it or time travel either.

We can make something that travels faster than time (to get to Mars in near no time) but we'll need so much energy that nothing on Earth (or everything on Earth) can make this happen.

It's an odd game, I tell you. There is no future, there are no years, no seconds, WE MADE THAT.

Ever heard of something called 'the 4th dimension'?

And even still, that doesn't stop us from going really fast, as if freezing ourselves for a certain amount of time just to 'wake up' in the future.

EmeraldSerenade June 6th, 2010 1:57 PM

I wouldn't like to time travel. I'd most likely do something stupid in the past and ending up messing up the future :x

Time Travel is an interesting topic, but I'm afraid of the bad things that can occur from it.

I doubt we'll be able to do this until the far future xD

Jolene June 6th, 2010 1:59 PM

People will never be able to time travel because if they could there would be time travellers walking around now.

If only scientists knew to roll the time ball. It would shake up the time stuff and we would time travel.

Time flies...

Can't really add much on what's already been said, time slows down relative to you as you approach light speed. One theory suggests that with negative mass you can achieve FTL travel but then you have the problem of gaining negative pass which is unlikely unless we can do something magical with anti-matter or the likes.

Gymnotide June 6th, 2010 8:55 PM

Fun, vaguely-related fact time!
If you view time as relative, it is possible to stop time by looking at a clock rather intently. The steps are a bit too complicated for me to care to type up here, so here's a link instead:

ummmmm yh thats kinda what I meant to do I was trying to just do a recap of everything we said cause it was all a bit confusing and split up so I decided to string it together into one post as to make it easier to read...........
though I suppose I did kinda make it a very long sentence but I didnt know that grammar was extremely necesary*_*.....and I suppose I should of been more clear what I was doing so in total I was just recaping on what had already happened and composing all the posts into one solid theory!;)

Pokémon Ranger ✩ Moriarty June 7th, 2010 5:17 AM

There's a 1990's radio play called Earthsearch by James Follett that deals with this very issue. Only, he argued that because you were traveling at the speed of light, time around you passed faster. So the protagonists return to Earth thinking only a thousand years had passed, and it turned out that three million years had gone. And, er, so had the Earth, hence the title of the thing.

It's a totally awesome production, btw. If you can find it, it's worth a listen.
