This may come off as a surprise for some.
Since I'm notorious for my "post your opinion" type threads.
Appropriately I decided to post this thread in the Fast Thread section because... Well... It's a fast thread [B]thread[/B]. Or a thread in the fast threads sub-forum. A question thread on "how do you explain time travel?"
Is there a way to do it in real life? Are we close or not so close in achieving time travel?
Course, typical response is "get your head out of the sci-fi gutter nerd!", "you're easily influenced."
Please, I have a firm understanding of reality, I know I say stupid shit but come on.
Or an alternative question that I ask is, "how do you explain time travel as it is shown in Video Media, or just books?"
What are some ways to explain how TV/Movies/Books/Games presents it?
You can look this up on the internet fairly easy. Traveling back in time is impossible but traveling forwards (as in faster than normal) is possible.
To achieve this you'd have to be going nearly as fast as the speed of light. [url]http://en.wikipedia.org/wiki/Speed_of_light[/url]
But as of right now that's impossible.

I heard of something like this in an episode of Game Theory on youtube when the guy was explaining the time travel mechanics of Chrono Trigger.
Step 1. Achieve the ability to keep a human safe in a rocket while it goes around the world really really fast.
Step 2. Keep doing this for a while.
Step 3. Land on earth.
Congratulations, you have traveled to the future! Bad news, You've missed the life and death of some of your loved ones and have no way of going back, Better get vaccinated for some new sickness you don't know about.
I don't want to talk about time travel, because if we start talking about it, then we're going to be here all day talking about it, making diagrams with straws.
Just ask uncle Rico

Personally, the only way I think time travel could be viable would be if time was variable between different universes, and interdimensional travel were possible without having to travel to the edge of the universe and travel through the interdimensional void as if it were space. For example, let's say Universe A (ours) flows at a steady 1 second per second, whilst Universe B flows at 1.5 seconds per second. A minute elapsed in Universe A would be equal to a minute and a half in Universe B, whilst in the inverse a minute spent in Universe B would be equal to about 40 seconds in Universe A.
THEN we consider the possibility of time variance being not only in speed, but in direction, aka time flowing in the other direction relative to our direction. To illustrate THAT, Universe C would run at 1 second per second, but inverse to the timestreams of Universes A and B, so from our perspectives in Universe A, a minute in Universe C would make time in Universe A appear to rewind 1 minute.
However, it would only be practical if different universes were on a different set of dimensions that weren't linked to our spatial dimensions, like if our particular universe was resonating on a specific frequency and different realities existed on other frequencies. In theory, that kind of interdimensional travel would involve tuning the "quantum frequency" of spacetime in a select area to make it cross the dimensional barriers into a reality on the same frequency, kinda like broadcasting radio signals on certain frequencies only it causes matter and energy to travel into alternate universes. No idea what kinda machine could broadcast an object into a different quantum frequency, though.
I've read a few articles about the possibilty of making time machines out of 'wormholes' by exploiting time dilation. The basic theory revolves around grabbing one end of the wormhole and setting off into space at luminal speeds, so that time dilation causes that end of the wormhole to experience less subjective time passing. Essentially the stationary wormhole will 'age' faster, meaning the other end of the wormhole exits into the past. Like the twin paradox thought experiment.
Technically speaking, any method of faster than light travel counts as time travel since you're virtually skipping the time it should take to cross whatever distance you're travelling, relatavistic effects notwithstanding. And time dilation is a measurable phenomenon that is very close to time travel in my opinion. In fact, you can see it yourself if you have access to two atomic clocks and a concorde.
When the object enters the timestream, time begins to correct itself. Let me use this example: Imagine four balls on the edge of a cliff. Say a direct copy of the ball nearest the cliff is sent to the back of the line of balls and takes the place of the first ball. The formerly first ball becomes the second, the second becomes the third, and the fourth falls off the cliff.
Time works the same way.
Travel - to make a journey
In this definition I do not think time travel is possible. Let's say I die later this year, in 2014. Let's further say that I have a time machine right now(I don't btw). How can I travel to 2015 when I died the year before?
If you mean 'travel' as in exploiting the effects of faster than light speeds, then yeah I guess.

all you dying in 2014 would mean you traveled back to 2014 after going to 2015

"The Doctor: People assume that time is a strict progression of cause to effect, but, actually, from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly... timey-wimey... stuff."
