Einstein was right about relativity, again. NASA's Kepler space telescope has beamed back the latest evidence that light can be bent by gravity, an element of the theory of general relativity. It's not that astrophysicists expect observations to contradict Albert. But the findings represent the first time the phenomenon has been detected in a binary star system, according to NASA. In this case, a dead star, known as a white dwarf, bent the light from its partner, a small “red dwarf.” The density of the much smaller white dwarf is far greater than that of its partner.

I saw Feynman only once, "live" on stage at Pasadena City College in the early 1960s, where he gave a superbly lucid and uniquely "Feynmanesque" lecture on relativity theory to an entirely enthralled lay audience. The most memorable comment of the evening did not come from Prof. Feynman but from a perhaps 14-year-old listener, who turned to his buddy at the end of the performance and said, "You gotta admit that guy knows what he's talking about!"

Squinting into the dark heart of the Milky Way, astronomers have discovered the closest star yet to the galaxy's supermassive black hole. The relatively dim star, S0-102, takes just 11.5 years to circle the black hole. The previous record-holder, S0-2, took 16 years to make its way around. A black hole is a star whose mass has collapsed to a point, a singularity. Its intense gravity distorts space-time so much that not even light can escape. The one at the center of the Milky Way contains the mass of 4 million suns.

All Santa skeptics, please take a look at the North Carolina State University website. Several professors in the school's Department of Mechanical and Aerospace Engineering recently asked their students to explore the aerodynamic and thermodynamic challenges of delivering gifts to millions of children worldwide in a single night from an airborne sleigh. The results, posted at web.ncsu.edu/abstract/tag/science-of-santa , posit that Santa Claus is a brilliant engineer and physicist.

The National Science Foundation announced last week that Livingston, La., near Baton Rouge, and Hanford nuclear reservation in Washington have been chosen out of 19 candidates for one of the largest research projects in foundation history. The project will attempt to detect gravitational waves for the first time, a discovery that could help explain the origins of the universe. The two sites will operate as a single observatory.

A key prediction of Einstein's general theory of relativity has been confirmed by an experiment showing that the Earth's rotation drags the surrounding fabric of space-time along with it. The phenomenon, known as frame-dragging, was one of the last untested predictions of general relativity. "Frame-dragging is like what happens if a bowling ball spins in a thick fluid, such as molasses," said Erricos C.
