"The research is already causing controversy among physicists. What bothers them is that if light could travel forward in time it could carry information. This would breach one of the basic principles in physics - causality, which says that a cause must come before an effect. It would also shatter Einstein's theory of relativity since it depends in part on the speed of light being unbreachable."

...and all along the thinking has been that the stock market is an anomoly where cause follows effect.

If that speed of light story turns out to be true, I can see an another Einstein on the way--that is, someone who will develop complex (abstract) theories from this discovery.

Going to be interesting.

If in fact what Wang has done is proven valid, all of our lives will be change forever. Very hard to fathom what he has done, right up there in accepting infinity.

Laser Shoots Down Rocket for First Time
By Jim Wolf

WASHINGTON (Reuters) - A laser-based system developed for the U.S. Army and Israel has shot down a rocket in a successful test of breakthrough defense technology, the Army said on Wednesday.

The test was the first in a series before the high-energy laser designed by a team led by TRW Corp. is handed over to Israel in coming months to help protect its northern borders against short-range rocket threats.

``We've just turned science fiction into reality,'' Lt. Gen. John Costello, head of the Army Space and Missile Defense Command, said in a statement released by his headquarters in Huntsville, Alabama.

He said the shoot-down, which occurred Tuesday at the White Sands Missile Range in New Mexico, showed ``directed energy'' weapons systems like lasers ``have the potential to play a significant role in defending U.S. national security interests worldwide.''

A laser -- short for Light Amplification by Stimulated Emission of Radiation -- is an intense, highly directed beam of energy. The one developed for Israel derives its energy from a carefully controlled deuterium fluoride chemical reaction.

Moving at the speed of light, such highly focused energy can shoot across great distances with minimal spreading out or loss of intensity. Theoretically, such a beam could knock out targets at distances ranging up to thousands of miles. That was the idea behind a space-based missile defense shield like the ``Star Wars'' system first suggested by President Ronald Reagan on March 23, 1983.

The ground-based, short-range air defense system is formally known as the Tactical High Energy Laser/Advanced Concept Technology Demonstrator (THEL/ACTD).

For the first test of its defensive capabilities, a Katyusha rocket carrying a live warhead was fired from a rocket launcher inside the test range.

Seconds later, the laser, located several miles away, detected the launch with its Israeli-built fire control radar, tracked the streaking target, then ``engaged'' the rocket with its beam, Cleveland-based TRW said in a statement.

``Within seconds, the 10-foot-long, 5-inch diameter (3.13 meter) rocket exploded,'' TRW said in a statement from its Redondo Beach, California-based Space and Electronics Group, the program's prime contractor.

Major Gen. Isaac Ben-Israel of the Israeli Ministry of Defense was quoted by TRW as saying the successful test was ``an exciting and very important development for the people of Israel.''

``With this success, THEL/ACTD has taken the crucial first step to help protect the communities along our northern border against the kind of devastating rocket attacks we've suffered recently,'' he said.

Tim Hannemann, executive vice president and general manager of TRW's Space & Electronics Group, said the test provided an opportunity ``for our customers to consider developing more mobile versions'' of the system.

THEL is a ``transportable'' system contained in several truck-sized shipping containers. The system stems in part from a commitment made in April 1996 by President Clinton to then Prime Minister of Israel Shimon Peres to aid Israel in developing a defense against Katyusha rockets fired by Hezbollah guerrillas from southern Lebanon.

Clinton is due to decide by November whether to begin deploying a ground-based national missile defense against what U.S. officials see as potential threats from countries like North Korea, Iran and Iraq. Lasers are not due to play any role in the initial phase of any such deployment.

Subcontractors for the system tested in New Mexico are Ball Aerospace & Technologies of Boulder, Colorado; Contraves Brashear Systems, L.P., of Pittsburgh; and Israeli firms Electro-Optic Industries of Rehovat; Israel Aircraft Industries of Yehud Industrial Zone; Rafael of Haifa; and Tadiran of Holon.
