Black Holes and their Spin


Posted By on May 29, 2007

There are two basic characteristics that describe black holes: Mass and Spin. Mass determines the size of the event horizon, the gravitational mass, and many of the ways the black hole can gravitationally shred people, planets and just about anything else. Spin is related to the magnetic field (which can also shred people because of the magnetic properties of water), and it exerts many relativistic effects on its surrounding, such as...

The catch was, while none of these stories had previously had related press releases, many of...

This mornings first press conference spanned the scales of the Universe. From a high speed dwarf galaxy only 1/20,000 times the size of our galaxy, to a new picture of M81 (a nearby spiral galaxy – image shown), to information on how a lack of gravitational pull is causing the local group to wander away a local void, the scientists took us on a wild ride through the universe.

What really caught my eye was the three scientists and their three Apple laptops. And, at the back of the room, Apple affiliated folks (not sure, but I think Apple Employees) were...

One of the odd side activities at AAS meetings is the search for neat give aways from the different space missions, companies, and publishers. These items generally take the form of lanyards, pens, and posters. I picked up something kind of new and neat and just in time for pool parties last night : A WMAP beach ball depicting the cosmic microwave background. I’ll now be able to toss the fingerprint of the big bang around my...
