/. are techie with possible needs for more robust OSs. How many support 'older' folks? The ease of use makes them a great option instead of constant WinUpdates. You can log in a set bookmarks in the bar for relatively easy access. Bigger screen at 1/2 the cost of an iPad...althought the newer 10.2" iPad is a great value and works 'kinda' like phone they already know.

Astronomers Discover 33 Pairs of Waltzing Black Holes 101

Posted by ScuttleMonkey on Monday January 04, 2010 @03:59PM from the teach-them-to-foxtrot dept.

Astronomers from UC Berkeley have identified 33 pairs of waltzing black holes, closing the gap somewhat between the observed population of super-massive black hole pairs and what had been predicted by theory. "Astronomical observations have shown that 1) nearly every galaxy has a central super-massive black hole (with a mass of a million to a billion times the mass of the Sun), and 2) galaxies commonly collide and merge to form new, more massive galaxies. As a consequence of these two observations, a merger between two galaxies should bring two super-massive black holes to the new, more massive galaxy formed from the merger. The two black holes gradually in-spiral toward the center of this galaxy, engaging in a gravitational tug-of-war with the surrounding stars. The result is a black hole dance, choreographed by Newton himself. Such a dance is expected to occur in our own Milky Way Galaxy in about 3 billion years, when it collides with the Andromeda Galaxy."
