Verified answer

Time is too much of a complicated subject to write it in Haiku. I will not try and attempt it, sorry,

Time travel is impossible. Time is a measurement of the forward motion. The forward motion is a constant. It cannot be reversed or fast forwarded. We can't go back and see the past because it has already been done, already affected our future, and no longer exists. We cannot travel to the future because it hasn't happened yet, simple as that.

However, the closest you can get to "time travel" is defying the system of time measurement on Earth. Say you have two twins. One travels to a very distant object in our solar system and attempts living there for a year. Because the measurement of time is much slower the farther away from the sun you get, the twins will be different. Twin one, the twin on Earth, will look much more aged whereas the twin two will be looking much younger. They will still be the same age, though, because they've both lived the same span of time.

I hope I was able to present this clearly enough to be understood, and sorry once again that it wasn't in Haiku.

Possible, I think so....

Welcome to the companion Web site to the NOVA program "Time Travel," originally broadcast on October 12, 1999. In the program, leading physicists delve into the mystery of whether time travel is possible, and if so, how one might go about building a time machine. Here's what you'll find online:

Sagan on Time Travel

Listen to the late astronomer and Pulitzer Prize-winning author's insightful and delightfully droll views on everything from wormholes ("very Alice in Wonderland") to the nature of time ("one of those concepts that is profoundly resistant to a simple definition"). (text and RealAudio)

Traveling Through Time

In this excerpt from his 1998 book Time: A Traveler's Guide, Clifford Pickover, an IBM researcher and science writer, declares that "time travel is possible." Find out why he is so sure.

Think Like Einstein (Hot Science)

Albert Einstein showed that space is curved, time is relative, and time travel is theoretically possible. Here, do a simple thought experiment and learn to think like the century's greatest scientist.

Timespeak

What you would call a time machine physicists term a "closed timelike curve." Steep yourself on the concepts and conjectures, the dialects and definitions that physicists rely on when musing about the possibility of time travel.

sorry if i'm no poet but apparently time seems to exist 'consecutively' (i couldn't come up with a better term) only to us, that is, really it's only a fourth dimension just like the other three and from various other perspectives it may as well exist all at once just like they do. so in effect if we could figure out a way to somehow wrinkle up the space-time continuum then time travel would be possible. unfortunately no one has the slightest clue as to how this might be done. as soon as they do, tho, i'm heading back to about 1700 and you'll all have to read about me on wikipedia coz i don't plan on making it back.

It seems to me that time travel is not possible. "Travel" implies distance, and time has nothing to do with distance. Moreover, the only part of time that has any real existence is the present. You can't travel to the past; it existed as the present, but exists no more. You can't travel to the future; it doesn't exist yet. Thus, we are stuck in the present.

Here's my very weak attempt at haiku:

The past is no more.

The future is not yet here.

Now is all there is.

"Dr Who" told me how the Tardis does it but I am sworn by the Interplanetary oath never to reveal the secret.

The Tardis is really bigger on the inside than the outside.

The chronarchy waits

Time rules and the tardis vworps

What decade is this?

Time travel is too far fetched for me it doesn't exsist so it's something i never think about mate.

I believe in it but maybe interdimensional is more sane?

Yesterday I knew.

Tomorrow go back in time

Ask me yesterday.
