From wikipedia:

In physics, a gravitational wave is a fluctuation in the curvature of spacetime which propagates as a wave, traveling outward from a moving object or system of objects. Gravitational radiation is the energy transported by these waves. Important examples of systems which emit gravitational waves are binary star systems, where the two stars in the binary are white dwarfs, neutron stars, or black holes.

In Einstein’s theory of general relativity, the force of gravity is due to curvature of spacetime. This curvature is caused by the presence of massive objects. Roughly speaking, the more massive the object is, the greater the curvature it causes, and hence the more intense the gravity. As massive objects move around in spacetime, the curvature will change. If the objects move around in the right way, ripples in spacetime can spread outward like ripples on the surface of a pond. These ripples are gravitational waves.

New Domain Names Could Come in Mid-2008

AP:

New Internet addresses for general use could start appearing in the summer of 2008 under a timeline the Internet’s key oversight agency announced Thursday.

The Internet Corporation for Assigned Names and Numbers invited public comment on procedures for creating new names, the first expansion for general use since 2000. Names added since then have been limited to specific regions or industries.”

MySpace Aims to Stop Reposting of Videos

AP:

MySpace, a networking Web site owned by media conglomerate News Corp. (NWS) (NWS), said Friday it launched copyright protection software for video content.

The feature, called Take Down Stay Down, prevents users from reposting videos that have been removed at the request of the copyright owner.

MySpace has several other copyright protection features already available, such as an audio filtering application which screens audio files to prevent people from uploading bootlegged music; a video filtering application, which screens video files to prevent illegal video uploads; and a Content Take Down tool, which allows copyright owners to request unauthorized content be taken down.

On Carrier in Gulf, Cheney Warns Iran

Vice President Dick Cheney used the deck of an American aircraft carrier just 150 miles off Iran’s coast as the backdrop today to warn the country that the United States was prepared to use its naval power to keep Tehran from disrupting off oil routes or “gaining nuclear weapons and dominating this region.”

Audio Back Story With The Times’s David Sanger (mp3)

Little of what Mr. Cheney said in the cavernous hangar bay of the aircraft carrier U.S.S. John C. Stennis, one of two carriers whose strike groups are now in the Persian Gulf, was new. Each individual line had, in some form, been said before, at various points in the four-year-long nuclear standoff with Iran, and during the increasingly tense arguments over whether Iran is aiding the insurgents in Iraq.

But Mr. Cheney stitched all of those warnings together, and the symbolism of sending the administration’s most famous hawk to deliver the speech so close to Iran’s coast was unmistakable.

Romney’s Estimated Wealth in Millions

Republican Mitt Romney is expected to report financial assets between $190 million and $250 million, an amount that would likely make him the wealthiest of the 2008 presidential candidates.

Knoxville Zoo Displays Albino Alligator

This white alligator has it made in the shade. Without an alligator’s normal dark camouflaging color, the new inhabitant at the Knoxville Zoo would not live long while exposed to predators or the sun.

In an exhibit made to look like the Louisiana bayou with tree stumps and hanging moss, the 12-year-old American alligator spent one recent afternoon basking under a heat lamp beside a warm pool with one claw lazily dipped in the water. If outside, her skin would burn in the sun.
