TIME TRAVEL

WHENCE THIS CREATION HAS ARISEN - PERHAPS IT FORMED ITSELF
OR PERHAPS IT DID NOT - THE ONE WHO LOOKS DOWN UPON IT, IN THE
HIGHEST HEAVEN, ONLY HE KNOWS- OR PERHAPS EVEN HE DOES NOT KNOW.
-- THE RIG-VEDA

People who have seen the movie- time machine will defenately remember the time machine used in the movie, the one with some rotating semi sphers.. Perhaps a practical time machine would be similar.

Light consists of particles called photons. Energy of these photons is proportional to their wavelength. When you are looking at a clock, light riflecting from it falls on your eyes and you can see the hands ticking away.. now consider same watch when kept inside a gravity sphere( all planets are gravity sphers but very large in size for our use, force of attraction at the center of this sphere is zero as forces from all the sides cancel each other) light reflected from the watch have to work its way out of the sphere and looses energy, Because of resultant increase in wavelength you see the same incidents(like second hand ticking) for a longer time(just like streched a rubber band which appears longer) and thus appear slower.

Now consider a man sitting inside of such sphere, his heart or any other growth of his is just like a clock and would appear slower to a person outside.Now for the light falling into the sphere, it gains energy and thus its wavelength shrinks and outside world seems faster to the man inside. Apparently he is on his rapid motion along time dimension compared to normal speed of one second per second.

Sounds simple huh? constructing a gravity sphere is something that needs a lot of time and money.... but hey it is not impossible... its just too complex.

For those who think all that above is fictious and foolish... i can only say you remind me of my grandmother when i tried to convince her that there are no real people inside of a t.v... LOL stay glued for time travel to past
