time travel?

whoa. Mind=Blown

I'll read this later when not on my iPod :0

This is actually pretty close to what my physics teacher told me when I ask. (yes I asked just for you xD) Assuming you're leaving earth at say the speed of light. That means it'd take you a year to get a light-year away. Since the speed of light is the max speed an object can go, yes time travel the way you're saying is possible.

If I gave you to ice cream cones (no icecreem) and you put them end to end (skinny end together) the point at which they meet should be thought of as the present. The end of the cone is a light year away. a body can not move through the past, so you'd have to go forward. you will be moving your present with you, while leaving their present behind you. There for you'd be traveling into the future.

If you were a light year away, and you sent light to your friends house, a year later, if you called him, even if you were able to, a light year away would delay your conversation by longer then a year, since nothing travels faster the light, neither can radio waves. By the time your friend would be able to communicate that he saw your light, it'd be atleast 10 years after you sent it.

traveling the speed of light for 20 years, you wouldn't age yourself because you are stuck in the present, and everyone else is in the past, but when you came back it wouldn't be earth 2042, it probably be earth like 2212. because you never aged, and everyone else did, every bit of technology would be new to you. but even though is theoretically possible, it's not likely to achieve because: The terminal velocity of something is far below that of light speed, and it takes mass to move it faster, and more mass means more energy spent moving it. If you were in a craft going light speed, you'd have to add mass to it until you reached the right amount, and after that point you'd have so much mass and be traveling so fast, that you'd stop suddenly. you wouldn't age for about 1 second. is all of this making sense?

I just re-read this and I semi-agree with what Bowy said.

You mention you're on the phone with a friend. Well seeing how Radio waves travel much slower than light there would be a noticeable delay between you talking and you're friend hearing it, for this example I'll call it lag time.

If you're 2 light minutes away from Earth we can hypothesize that Radio waves take double the amount of time. So 2 Light Minutes (LM) = 4 Radio Minutes (RM)

We can safely assume that if you send something faster then the speed of light, known as the particle dispersion acceleration theory, that you're friend will receive the object at 1 LM.

This is assuming that 1 Particle Minute (PM) is 1/2 of an LM.


Let's give an example.

At 10:30 you say to your friend through your phone. "Hello!"

At 10:31:30 you partically charge an apple to your friend.

At 10:32 they receive the message and the apple at the same time. Radio waves took double the time and Particle minutes took half the time.

The theory that if something moves faster than light it's time travel is exactly that. A theory. The secondary theory in which I mentioned takes the basic concept of atoms, in which everything is made, and bends them through your space craft with some very complex magnetics.

Since humans can't, however, travel at the speed of light we can not prove or disprove the theory of using atoms to boost light speed.

Light bounces off of atoms, so if we move the atoms there are no light and therefore we can travel through and faster than light.


That is what I think on this. Any questions? (:

BTW if you tossed an apple at your friend from space, they'd have very hot/burnt/incinerated apple sauce.

Tasty.

and actually... Sno and I were wrong. Radio waves travel at the speed of light... so...

Woahh
