Time travel is NOT POSSIBLE?
Dear heatwave218,

You state that "Time travel is NOT POSSIBLE". Maybe you're right. But quite a number of reputable physicists have developed theories of how it might be achieved. For example, read the following:

Phys. Rev. D 9, 2203:2206 (1974),
[Issue 8 : 15 April 1974 ],
Rotating cylinders and the possibility of global causality violation by Frank J. Tipler, Department of Physics and Astronomy, University of Maryland, College Park, Maryland 20742,
http://prola.aps.org/abstract/PRD/v9/i8/p2203_1

You may need to buy access to PROLA in order to read the full-text article.

While Dr. Tipler has caught a lot of flack over his "Omega Point" theory, he is a trained physicist of some repute and, so far as I know, no one has repudiated his work on global causality violation which was based on the work of G?del and van Stockum.

And he is not alone in his speculations about the physics of time travel. Physicists such as Stephen Hawking, Kip Thorne and Michio Kaku have discussed serious theories of time travel.

An accessible treatment of the possibility of time travel may be found in Dr. Michio Kaku's book, "Hyperspace : A Scientific Odyssey Through Parallel Universes, Time Warps, and the 10th Dimension" (ISBN: 0385477058).

In that book Dr. Kaku writes, "Most scientists, who have not seriously studied Einstein's equations dismiss time travel as poppycock". But he then goes on to demonstrate that those scientists who are knowledgeable do not dismiss the possibility.

I urge you to do some more study on the subject before you categorically reject the possibility of time travel.

Of course none of this has to do with the development by IBM of the photonic silicon waveguide. The principle of operation of that device is well established (i.e., the difference in the speed of light in media of differing refractive indices).

And my advice to you is: Carpe diem! Do not "live for the future" rather, live in the moment (perhaps with an eye to the future) for as Herrick so eloquently put it:

"Gather ye rosebuds while ye may,
Old time is still a-flying;
And this same flower that smiles today
Tomorrow will be dying."
