speed of light

[TKAzA]

with time travel , this is interesting because we all have our own time lines and pasts so think of this like a unique line in space if you go back on your line via another route you will in adversely re write your line ( butterfly effect, or ripple effect), this comes now down to are our lives pre written or under our control if so how can you exist in the same time and then go back to the present with your time line reconnecting unless our lives are pre written on a path, if our lives are pre written then if we can make use of this line we can see the future but will this mean we can travel through time, in a way yes

if any one has watched the movie donny darko it uses the same principle

time travel of a object that has a existing in a time and space line with out causeing a butterfly effect, nope and nope

but when i say see the future, i mean that if you see someone move from one side of the room to the other at such a speed, u would see it before it happened! therefore, predicting the future, but does that then mean we dont have free will??
freaky :S

Sounds like my nights with jim bean black just I trow up and the room stops spinning.

We discussed a lot of similar things here.
The Universe

Whilst most theories would suggest we can't physicaly go faster then the speed of light (in a vaccuum)it is theoreticly possible to take short cuts through space. For instance a warp drive would allow for the compression of space or a stable worm hole would give us access to parts of space quite quickly.

I know this all sound a bit star trek but bare in mind most of the stuff there is based on actual scientific theory.

As for time travel. I honestly can only see us ever travelling forward in time (or rather doing so more quickly because we are infact going forward in time.)

Going faster then the speed of light wouldn't mean you saw things before they happen. It would mean things would happen before you see them.

Red dwarf has a great qote along the lines of.

"When you're going faster then the speed of light, by the time you see a asteroid you've already passed through it. It's brown trousers time for anyone, even if you have got an IQ of 6000."

Time travel backwards, why is it impossible? Time is a dimension, so if we travel dimensions, we can travel to different times.

thats like saying you can see the backside of a block because the viewing direction is a dimension?

[ferret]

if any one has watched the movie donny darko it uses the same principle

let's not use fictional movies here - in donnie darko he found that the fourth dimensional tool was water.

Time is just a concept, not anything physical. Time is simply Distance/speed. It is only because we percieve things as having a past, present and future that we feel obliged to consider everything in this blinkard way.

Thats not to say i think time travel is possible at all, i just feel it is more plausable to travel Back as oppose to forwards in time. For the simple reason that one could re-configure particles' direction and speed to reflect any time in history. Doing the same about the future would be guess work surely.

But who knows, we can all speculate and assume until the cows come home! We just have to wait and see.

[Athlete{UK}]

Actually most current thoeries point to time being far my physical then an abstract thought. It's generally accepted now as the fourth dimension.

[Sacul15]

Time travel is already possible. Chuck Norris has done it on multiple occasions.

[Dead-Inside]

Well that was serious.

[daap]

Well that was serious.

i'm sorry...
Dont knwo if anyone watches star-trek but they got some real good theories en ideas about interstellar and timetravel.. (the have a lot off scientist in there story writing team)

Okay, to begin with, time is a concept - that is, it does not exist. Therefore, time travel is impossible.

Next on the list: traveling at the speed of light - First off, accelerating to the speed of light. Even if we could accelerate to this speed, it would take so long that by the time we reached the speed of light, we would already be at our destination, and then you have to slow down again in time before you get there.

Now you may say that we develop some kind of super high thrust engine that can accelerate us to the speed of light in mere seconds - guess what? Accelerating that quickly would amount to a huge amount of force on the vehicle, as well as everything inside it, which would make a big mess.

Now let's say you have managed to find a way around this and created some kind of dampening field inside the vehicle, so that the forces have no effect on the vehicle's passengers - There is still one final hurdle; everything surrounding the vehicle would also experience these forces as the vehicle collides with it - air particles would accelerate to deadly velocities, and an enormous pressure wave would result. You would essentially create an explosion in the path of the vehicle.

Face it, with our current technology, and most likely our future technologies, time travel, as well as traveling at the speed of light, are two major impossibilities.

[Sorrow]

Yeah we need to find a way around it, warpbubbles, shifting into other dimensions etc.
