What theory on time travel do you find easier to believe?

Whenever my friends and I are hanging out, we always seem to end up arguing about which time travel theory is the most legit. Most of my friends say that the "Back To The Future" theory is right, but I say that theory from "LOST" is the right one. What do YOU guys think?|||I'm not familiar with the t.v. show "Lost", but I am with "Back to the Future". Einstein's already been mentioned, but I'd propose that according to his theory of time dilation we are all time travelers already. Consider a rotating fan. The outermost edges of the blades would be moving more quickly (distance per unit of time, not rps) than the inner lengths of the blades or the hub, therefor the edges would be "aging" more slowly than the rest of the fan, one end of an object traveling forward through time at a different rate than its other end. Likewise, a point or object (or person) at the equator travels a greater distance each day than one near the polar regions. As suggested, we'd need a "thing" or a transport which could safely carry us near (not at or faster than) the speed of light to travel forward a great length of time. I think moving forward through time at a controlled rate and moving backward through time at a controlled rate are two different mechanics, as the forward happens to us all "naturally" at our own individual rates. Maybe an answer to both would be similar to a warp drive, but instead of warping space around us we'd warp time and leave space as is. I picture the H.G. Wells time machine, but why not a DeLorean, right?





Going backwards in time would require a science not yet discovered or understood. Physicist Jack Sarfatti did some work with FTL (faster than light) transmissions, signals sent through a chamber of cesium gas (?). Him and others doing the same experiments claimed speeds over the speed of light (300 times, was the highest I recall), their "evidence" being that the receiver seemed to receive the signal before the transmitter sent it (maybe based on time stamps?), a sort of reverse time dilation: traveling FTL moves you backwards through time. The oldest note of this suggestion I know of was in the book "The Dancing Wu Li Masters: an overview of the new physics" published in the 70's or 80's, and Sarfatti had discussed it in a "Time Travel" episode of a Discovery Channel show... I'm thinking "Beyond 2000" but it was around 1998-1999 so I can't say for sure. If there is any truth to this idea, then a vehicle or even a transporter beam might be capable of sending someone backwards in time as well as forwards. However, travel could be limited per the idea that the traveler could not go back to a time before the time machine was built, which would mean Dr. Brown could not travel back to the old west. The only "loop hole" I can see for this would be either: A) discovering a "time warp" engine which could warp at FTL speeds (maybe a flux capacitor?), making the "time span" of the vehicle relative and not fixed or linear; or B) discover a way to use a pre-existing cosmic body/system for travel so you could go as far back as its creation, black holes or worm holes seem like the usual suspects, though it may be something we've yet to discover or consider. Maybe even a Star Trek variation, where the Enterprise is simply a time traveler like her crew but the sun itself acts as a carousel-like time machine, allowing travel between the time span of the sun and not just the time span of the ship.





Einstein's theory of time dilation has been tested and proven through use of atomic clocks and space travel, but I've yet to see any major acceptance of Sarfatti's idea of FTL signals. However, we can't fully define "time" any more than we can fully define "gravity" (can we say for certain that they are indeed causes and not only effects?), so the true answers may be totally beyond our current expectations. My greatest optimism for time travel lies in knowing we once believed vehicular flight was impossible, and we believed traveling faster than sound was impossible, and we even believed sailing around the world was impossible, so the claims that time travel is impossible do not dissuade my contemplating the matter.|||Under ideal conditions, any relativistic effect is a time travel event, be it moving quick through space to event changes across vast distances to black hole's growth exceeding stable limits. All of them have the ability to affect the observer's time table. As for tv shows and movies, they're for entertainment purposes. In all likelihood, actual time travel (with the exception of traveling in a fast vehicle) will be a terribly boring experience, because macroscopic relativistic effects are rarer.|||I heard that using relativity of the best ,Albert Einstein we will be able to travel to the future!


Just when we find something witch has the speed of light .


An example;


when we travel in this "thing" for 2 years, we will find the earth 40 years later!


thanks by-by|||I think that people that have traveled to our time are lost and want to get back to the future.





Thus, either one could be right or wrong or right and wrong at the same time. Great Scott.|||I believe time travel is impossible.|||Not sure about either of those theories. Mine is that if time travel was at all possible, then why have we not had many visits from people who live in the future?|||http://www.youtube.com/watch?v=JkxieS-6W鈥?/a>
