The possiblity of lightspeed and time travel

So with the assumption that time (as we percieve it) progresses with the rotation of the earth, is it plausible that traveling around the world in a opposite direction directly along the equator FASTER the then world is spinning (aka lightspeed) is essentially traveling backwards in time?

I base this on the idea that someone traveling at or near light speed percieves time differently. So that if we sent a spaceship out at light speed, the total time for the people IN the ship would be less then the time that the rest of the universe percieves.

If going against the spin goes back in time, could going with the spin, but still faster, produce a time acceleration effect?
 
There is no backwards in space, no matter what direction you go in space you will be going forward in time not backwards, although the laws of Superman's universe are otherwise. The speed of light is 186,282 miles per second. There are theories that particles exist that move backwards in time instead of forward but they are only a theory at the time being.

That is a laughable statement, this isn't Superman the Movie or Hollywood.

The rotation of the earth has nothing to do with time as we perceive it.

against the spin, with the spin, geez, hopefully somebody will tell you why your understanding of relativity is flawed.
 
Renunconscious,

Whether laughable or not, every post here should be given some consideration without belittling. Several of your posts contain a bit of ridicule and for a first-time poster, this could mean the difference between never posting again and, possibly contributing a vital piece of the puzzle. Otherwise, I enjoy your posts and your discriminating mind. I think I can safely say that no one here has a corner on the truth or all the facts--whether it is about Titor's story (which I personally have big problems with) or the physics of time travel. As a long-time member here, I've learned that we sometimes have to be patient--even in the face of utter nonsense. The non-linear mind can sometimes find a "jewel" in the midst of pure trash. As I've mentioned before, I welcome all the new posters lately--even though some are "fixated" on the Titor saga. I read all of them and have found that I could find just as much information to support it as I can find to disprove it. Regardless, it has many people "thinking". Even the post about "local time" and the progression of the earth got me thinking. Not for long, I'll admit, but I believe that I have given this idea some thought in the past.
 
"The rotation of the earth has nothing to do with time as we perceive it."

But we percieve OUR "local time" (thanks zerubbabel for such a nice term.) based on how the sun rises and sets. Or as science has come to prove it, the rotation of the earth. We may be able to perceive time off of earth, but it is here that we have set the increments for it. WE set up years, minutes, etc. So in a sense of local time, how can we rule out that we couldnt effect our "local time"

Isnt it theorized by most scientists that faster-then-light travellers would experience a distortion of time. Saying that they may age less then the rest of the universe? Is that not in itself a sort of time travel. /ttiforum/images/graemlins/confused.gif
 
jassurkrul,

Lets take your scenario to a higher level. Consider the recently discovered "blazars". This is a highly energized Jupiter-sized glob of plasma that has been ejected at just below the speed of light. It is traveling at the fastest speed possible and yet still maintain its cohesion as a matter unit. At this level, relativity breaks down because it is at odds with quantum theory. The whole analogy of "time-stopping" behavior does not apply at this level. Conceptually, it would seem that matter traveling near the speed of light would emit photons that not only travel at light speed themselves but would have the added velocity of the matter ejecting it. This is not the case. However, a different case can be made at the quantum level. As a matter of fact, Machu Piku, a prominent young physicist, has come to the conclusion that any attempt at interdimensional travel will have to be done at the quantum level. Physics shows that if the ten dimensional model is correct, the only possibility of interacting with those dimensions is at the quantum level. Relativity forbids it at the macroscopic level.

I would highly suggest you read the following synopsis of where science stands today and where it is likely to go in the future. I would also note his conclusion that philosophical and theological questions need to be addressed as well. At this point in scientific history, your "musings" are as valid as any other. However, a healthy understanding of physics goes a long way in removing some of the uncertainties. Renunconsious is absolutely correct about that.
