Finding a star to call home

We live on a rocky little planet perfectly situated around a middle-aged G2 spectral type yellow star. In many ways, a very boring and ordinary star, but with an extraordinary difference: it has at least one habitable planet. And, in fact, one inhabited world with the right temperature and ratio of

Scientists Confirm ‘Impossible’ EM Drive Propulsion | Hacked

Later today, July 27, German scientists will present new experimental results on the controversial, “impossible” EM Drive, at the American Institute for Aeronautics and Astronautics’ Propulsion and Energy Forum in Orlando. The presentation is titled “Direct Thrust Measurements of an EmDrive and Evaluation of Possible Side-Effects.” Presenter Martin Tajmar is a professor and chair for Space Systems at the Dresden University of Technology, interested in space propulsion systems and breakthrough propulsion physics. A Revolutionary Development for Space Travel The EM Drive (Electro Magnetic Drive) uses electromagnetic microwave cavities to directly convert electrical energy to thrust without the need to expel …

Evaluating NASA’s Futuristic EM Drive

EM Drive

“A group at NASA’s Johnson Space Center has successfully tested an electromagnetic (EM) propulsion drive in a vacuum – a major breakthrough for a multi-year international effort comprising several competing research teams. Thrust measurements of the EM Drive defy classical physics’ expectations that such a closed (microwave) cavity should be unusable for space propulsion because of the law of conservation of momentum.”
