EINSTEIN'S MESSENGERS, LIGO AND THE SEARCH FOR GRAVITY WAVES

submitted by: nsf
Einstein's Messengers is an Award-winning 20-minute documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory. The video examines how LIGO is spearheading the completely new field of gravitational wave astronomy and opening a whole new window on the universe. It explains how LIGO's exquisitely sensitive instruments may ultimately take us farther back in time than we've ever been, catching, perhaps, the first murmurs of the universe in formation. Above all, Einstein's...

Phase-shift Plasma Turbine - Interplanetary Spaceflight

submitted by: MFerreiraJr
The Phase-shift Turbine consists of a set of concentric coils, axially rotated from each other, and feed by phased RF sources, producing radial and longitudinal sequences, which results in helical moving force, ionizing intake gas/particle/ion, generating continuous unidirectional thrust. It was designed in order to operate in atmospheric environments, mainly during takeoff, and in space to reuse exhaust gases from chemical rockets to booster the overall ISP, enhancing utilization of both...
