It wouldnt be you. You die and some one else like you(exactly(a clone)) would replace you with all your memories and feelings. You get vaporizerd... wait, thats a teleporter.
I don't get it, this just bends space-time, big deal; everything in the universe does to some extent, like being on Earth's surface means time is more dilated than if you were in orbit, this has nothing to do with going back in time. Also, unless going back in time creates an alternate universe, time travel to the past makes no sense as you'd create a paradox. By sending even one photon or atom or anything back you're instantly creating energy/matter, and at worst you'd create infinite energy, so this obviously isn't possible.

Oh shit just like the movie Primer
[QUOTE=Rach Runner;22315568]I personally don't believe anything is set in stone. (thus not believing in "fixed" events) And I'm talking about people changing the timeline for their own selfish gain. I could see it happening.[/QUOTE] I say things are only set in stone after they've happened. But all things have always happened. If you understand?
[QUOTE=GranaMan;22313797]If time travel was possible, i think we would have some kind of records in the history that some futuristic guy came and said "Oh Hejo, im korean!". And then fucked up the whole time line.[/QUOTE] What about going ahead into the future but not being able to come back?
What happens if you time travel to a spot where another you in the future is traveling to at the same time?
This is just a form of time dilation, really thats the best we're going to get. It must look really weird to the people on the outside though, you are either moving really slowly or are just a statue. I'd still go to the future, I would prefer it to the past by a long way.

And then fucked up the whole time line.[/QUOTE] Unless time travel was only possible like stated here (and suspiciously in Primer) that you can only travel back to when the machine was invented. Since we haven't invented it yet, there's simply no way to travel back to our time. Post 4000 give me 4000 funnies
If I could go back in time I would ask George Washington for a dance.
ik ook
All the people saying "OH MAN LOL PARADOXES ETC" - read the article! The machine can only go back to when it was first switched on, meaning you can't dick around with the past - at least, to a certain point.

So because you can only go back to a certain point it means you can avoid paradoxes altogether? Please.
So if you could only go back to when the machine was invented, what happens if you test it a few minutes after it's invented would you be a few minutes younger?

It's effectively a genesis device in a way. Make it big enough for people keep it powered at all times and if something cataclysmic happens in the future, we have an escape to keep the species going. And who knows, when this thing actually gets turned on for real someone MAY pop through.

I'm not a physicist by any means, but I'm not sure how time dilation is supposed to work at all. If you go at the speed of light, light won't catch up to you so time appears to stop? But this is just an optical illusion? How does that affect the flow of time at all?
No the faster you go time starts to warp slower. It's not optical it happens. It's the same with extremely high gravity.
[QUOTE=bravehat;22342503]And who knows, when this thing actually gets turned on for real someone MAY pop through.[/QUOTE] I can imagine that throughout the liftime of the time machine, plenty of people would want to go back to the instance the machine was turned on. If they did this, hundreds maybe thousands of people may come through at the exact same time.
wow, that room would get crowded fast :v:
Just wiki time-dilation man. Its to do with the speed of light always being constant (always the same) no matter how fast you are traveling. This is because speed is a relative thing - there is no fundamental 'at rest' in the universe, you can only be 'at rest' relative to something else which, from an external perspective, would be traveling [I]with[/I] you. Regardless, light would always be measured to be traveling at the same speed. Due to this, and the equation S=D/T the only thing that vary to accommodate this constant is the passing of time itself. An easier way to think about it. If you shine a torch and measure the speed of its light, and then get in a super fast spaceship and fly towards the light, and then measure the lights speed, both measurements of the speed of light would be exactly the same. I read a Brian Greene book recently, which said that we are all always collectively moving at the speed of light. Its just when we are at rest (relative to something with us) we are moving at this speed [I]through time[/I] (and so 0 time dilation). When we begin to move, this momentum is subtracted from our momentum through time, which causes time dilation. If we get up to 99% light speed our momentum through time becomes 1%. In this sense our combined velocities through time and through space always equal SOL. In this sense its much easier to visualize time as a dimension rather then something which allows change to take place.
[QUOTE=bravehat;22343007]wow, that room would get crowded fast :v:[/QUOTE] They would have to keep logs of who travelled back to when to avoid people going back to the exact same time.
[QUOTE=Eudoxia;22313834]Wouldn't this require, you know, unimaginable amounts of energy? On the other hand, it's just for a neutron, so it shouldn't be much... Too much, at least. Also, Causality violations.[/QUOTE] Causality violations would be avoided due to the fact that if a time traveler decided to alter our reality, only our timeline would be effected and not the time traveler's original timeline.
So basicly the scientist person turns the time travel-machine on, and suddenly everyone who in the future will use it pop out of it and flood the planet

Anyways, I doubt that the time machine will be able to send that much data back through time. It will probably only be able to send data in the form of a protons or deuterons or something.
There is already time travel. Only forward, not backwards. Stand by the Pyramids and time slows down. Not alot, hardly anything. But its still time travel. Because of the mass of the object. Try a Blackhole/Planet/Star and you will have alot greater success or you could try to go at a massive speed(99% of the speed of light) and you will time travel. Everyone has time traveled, maybe not alot. But a fraction.

If it works in the first place :v: EDIT: And I can't be the only who has realised that if that stays on for say, 100 years, whoever is in the future operating the machine could send particles back in a sort of code, and relay scientific discoveries back to us, and super accelarate our scientific progress, and then when our advanced selves reach the future in 100 years repeat the process and we have this fantastic jump.
i predict we switch on the machine an some sort of killer robotic army floods through.
