or maybee traveling to the past isnt possible and it is only possible to travel into the future.

i feel we are pretty close to making time travel a possibility. probally in the next few hundred years.
Having examined Einstein's equations more closely, physicists now realize that the river of time may be diverted into a whirlpool - called a closed timelike curve - or even a fork leading to a parallel universe. In particular, the more mass you can concentrate at a single point, the more you can bend the flow.
In recent years, new designs for time machines have been flying off drawing boards at the world's top science labs. Exact specifications depend on where in time and space you wish to travel. You'll need a hefty CPU to solve the relevant equations for your machine's precise size, shape, motion, location, surroundings, and so on; the more accurately you can nail down these variables, the closer you'll come to your intended destination.
The designs that follow don't have the panache of Doc Brown's DeLorean in Back to the Future or even H. G. Wells' brass and quartz dream machine, but they do put time travel within reach of anyone with a couple of fast spaceships, a supercomputer, and a solar-system-scale machine shop. Warning: Time-space distortions may not be stable and may collapse as you enter, so approach them at your own risk. Also, when going back in time, do not - repeat - do not kill your parents before you are born. Wired takes no responsibility for parallel universes in which you find yourself trapped for eternity.
Dr. Kaku is an internationally recognized authority in theoretical physics and the environment.
Dr. Michio Kaku graduated from Harvard in 1968, summa cum laude (highest honors), and number one in his physics class. He went on to the Berkeley Radiation Laboratory at the University of California in 1972, and in 1973 Dr. Kaku held a lectureship at Princeton University.
Today, Dr. Michio Kaku holds the Henry Semat Professorship in Theoretical Physics at the City University of New York (CUNY), where he has taught for over 25 years.
He has also been a visiting professor at the Institute for Advanced Study at Princeton, as well as New York University (NYU).
During the last part of his life and work, Albert Einstein was on a quest to find the "theory of everything", an equation perhaps only an inch long that would unify all four fundamental forces of the universe. Dr. Michio Kaku has continued this quest, and is the co-founder of string field theory, a leading candidate in the search for a "theory of everything".

thing i cant understand about time speeding up with light spead is say i flew a plane at say around mach 10 if it was posssible its not like the time speeds a few mins or even seconds so why at light speed which is just a speed ur moving at then back to the same piont again at the same speed should only take however amount of time it did in the first place meaning i travel at light speed for 5 minutes and its say around 5.00pm then come back again same speed to the same piont it should only be 5.10pm

so basicaly can what ur saying about alternet times but u change over to a difrent universe which to me would mean that there is and infinite amount of possiblities, the meaning of life is infinite
