MERGED: Is time travel possible?

[rodsky]

he is still 50 years older just like any of us 50 years from now, only difference is his mind stopped generating new experiences, he hasn't defied any laws of nature. a "real" time travel is going 50 years into the future with your current biological age intact.

I didn't use that as an example to illustrate actual time travel, but as an analogy to what you might feel if you've been suddenly transported to the future. It's exactly the same as what the comatose man might've felt after waking up 50 years later.

pero sir wala siay ni travel kay iyang lawas naa ra man sa Bed. maybe pasabot nimo puede ni sa atong imagination.

Again, please read my response to coolnezz's post. You guys must be having trouble with the concept of analogies. The comatose man is merely an analogy, not a direct example of travelling to the future.

Furthermore, travel by definition can be either of two things--spatial (i.e. delta of position, x,y,z, relative to a fixed point in space) or temporal (i.e. change in time). To appreciate this further, you must appreciate the fact that in our current understanding of the physical universe, spatial references (i.e. "travelling from one place to the other") can no longer be considered as purely a "space" operation/procedure, but a space-time one, where, x,y and z are coordinates of spatial reference, and another axis which I'll call T, which stands for time. Thus, space is not only in three dimensions, it's four dimensions, the fourth axis/component being time. Thus, when you say "travel", it can very well mean a temporal shift, rather than a spatial shift.

very easy to understand

everytime you travel at high speed, you're traveling to the to future, pero insignificant ang amount. mao nai gitawag og time dilation.

*edit
time dilation experiment

dunno.....

you guys watch too much HEROES!..

There is a big difference between watching a television series based on science-fiction or fantasy, and then claiming that time travel is possible only because of that TV series, and reading and understanding (even if only the parts that can be understood by a layman) the principles of time-dilation (when travelling close to the speed of light) as stipulated in Einstein's Special Theory of Relativity.

I bet the TS is a big BACK TO THE FUTURE fans

[coolnezz]

got better things to do than wracking my brain about time travel.
best left to the "scientist"

[ermitanyo16]

it's not possible!

[brownprose]

Theoretically, it is possible. Quantum Mechanics has it that in the subatomic world, particles defy the laws of Physics.

The idea of a "wormhole" was also forwarded back in Einstein's time which continues to this day an interesting topic among physicists.
