Letters from the November 27, 2004, issue of Science News
Dark Secrets Astronomers and physicists seem to speak of black holes as though they took matter completely out of the universe (“Information, Please,” SN: 9/25/04, p. 202: Information, Please). An evaporating black hole would not fizz away into nothingness. It would lose energy and reappear in normal space as a very dense object (complete with […]

Spinning Earth drags space
Slight deviations of two Earth-circling satellites from their expected orbits appear to confirm a curious prediction from Einstein's relativity theory.

Nanotubes: Knot just for miniature work
A new technique can spin individual nanotubes into durable ribbons and threads visible to the naked eye.

Particle hunt off, collider comes down
Despite tantalizing, last-minute hints of a long-sought, mass-giving particle called the Higgs boson, dismantling of the Large Electron-Positron collider has begun.

Hot little levers write beaucoup bits
Arrays of microscopic tips may offer a way to pack digital data more tightly and transfer it more quickly than is possible with magnetic hard disks.

Light step toward quantum networks
During the transfer of a quantum data bit from matter to light, a cloud of extremely cold atoms emitted a photon carrying a version of the cloud's quantum state.
