Exploring planetary structures via Lense-Thirring and more

If general relativity is correct, one of its implications, Lense-Thirring / frame dragging, should be able to be used to map planetary interiors. The Lense-Thirring effect is basically a twist in space near massive bodies such as planets, stars, and black holes. If proven, it...

More or less evidence for Lense-Thirring

If you perform an arXiv search on Lense-Thirring, you get about 200 papers directly related to the subject. Lense-Thirring is the GR concept purporting a 'twist in space' near massive spinning objects. Contrary to the claims of Gravity Probe B staff, due to noise in the data,...

Plasmonic Computer Data Storage: 10-100 Times Today's Capacity

"Plasmonic nanolithography" focuses light by exciting electrons on metal lenses, which write data on photo-sensitve disks. According to UC Berkeley professor Zhang, storage capacity 10 to 100 times today's may be possible."Engineers at the University of California, Berkeley,...
