i feel we are pretty close to making time travel a possibility. probally in the next few hundred years.
Interesting considering the "multiple worlds theory" of quantum physics.
Kudos to anyone who actually reads all of the following quotes, rather than scrolling by it, but it does pertain to the issue:
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
The above was written by Dr. Michio Kaku. His credentials:
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".
In other words, according to one of the leading physicists of the world you aren't too far off the mark in what you "feel" is possible. Heck,
there are probably some time travellers reading this right now
