can we do time travel if we rotate the earth in speed greater than the speed of light?

Yes, one aspect of time travel is theoretically possible. That is to say, according to Einstein's Special theory of relativity it is possible to travel into the future. How far in the future in a given time span depends how close to the speed of light you accelerate. Traveling at 80% of the speed of light according to Einstein's formula y=1/ Sqrt 1-v^2/c^2 ,(v=velocity, c= speed of light) the clocks on Earth will advance 1.667 times faster than the one traveling in space. Therefore, after a twenty year journey by the space travelers, (20 yrs time has elapsed by the travelers account) upon their return, there will have passed on earth 33.4 years.

At 98% of the speed of light, 20 years of travel at this speed, upon return, 100.4 years will have passed on earth.

This is the equivalent to traveling into the future, which is a form of time travel. Therefore time travel is theoretically possible. In fact, check out this site as the guy proclaims that we will be able to approach speed of light travel within 100 yrs.

Traveling back in time is debatable, as you would have to be able to exceed the speed of light to do that.

Plug in the numbers to this formula. speed of light c= 186,000 miles per second. For velocity, just multiply this number from .01 to .9999. Then just follow mathematical operations.

good luck

To Alan B. you got the concept but you sound skeptical. I am not sure that you numbers are correct, but that doesn't matter, you got the concept. Einstein stressed this; the traveler would be unaware of the time as it would appear to them to be normal. It' s if someone from Earth could somehow glimps at the travelers clocks they would notice that the travelers clocks were running significantly slower. Vice Versa, if the travelers could see the Earth's clocks run faster. Near speed of light travel also alters size and mass (space travelers become smaller but more massive).But these differences would only be noticed from outside not by the space travelers.

Oh yea, anyone traveling near the speed of light would know these parameters. There are no Dukes of Hazard in space. Nor any Oswalds of Drew Carey fame..

I actually do not believe time travel is possible. I think something else happens when moving at speeds close to the speed of light. I think that electrons have a set velocity at which they travel. When one travels at close to light speeds, my thought is that the electrons orbiting atoms in you body, your ship and everything else travelling with you slow down. Less orbits may result in less decay, ageing and I would think that your perception of the universe would be that of a VCR with someone on the fast forward button, that is if you could perceive it. Imagine riding a bike slowly and time is a person wanting to push you off. Then Imagine riding fast. Wouldn't it be sad if one were to travel at the speed of light to some distant world not knowing of this effect. All the shipboard clocks would appear to keep correct time according to the ship and an order to travel one year at 297,000 Km per second, would mean that we on Earth would see carry on for 14.1 years or so

Rotational velocity skill Angular velocity (Omega) and and linear action is in line. If this takes place then each thing which consists of crust would be thrown aside or earth could get away from solar's gravity container. get away velocity of earth = 11000 m/s easily Rotation velocity = 465.a million m/s If new Rotn velocity = 3 X 10^8 then each thing will pass off. Earth would be destroyed. playstation : Earth has (or could i say all and sundry in Universe) has composite action. Earth's rotation is the rotation of the solid Earth around its very own axis. Earth's revolution is the rotation of the solid Earth around solar.

***no speed greater than speed can be attained by any of the body

This the primary assumption and is followed by everyone

if we can attain a speed equal to the speed of light then the time period of one second will be infinite and thus we acn do time travel

but this is impossible by the resources present to human today

Without delving into the whys time travel is not possible.

A time traveler could embark on a journey at any time and it would spread throughout time and every body would be a party to it.

I would have gone millions of years ahead and back in time and let every one in on it.

No, if for no other reason than that nothing can move faster than the speed of light.

maybe but everybody will get really dizzy and get motion sickness
