More Evidence For A Preferred Direction in Spacetime
The evidence is growing that some parts of the Universe are more special than others One of the cornerstones of modern astrophysics is the cosmological principle. This is the idea that observers on Earth have no privileged view of the Universe and that the laws of physics must be the same everywhere. Many observations back […]
Third experiment sees hints of dark matter
September 7, 2011
A third experiment has detected tantalising signs of dark matter. The finding raises more questions than answers, however, as two other experiments have found no sign of the mysterious stuff, which is thought to create the gravity that holds spinning galaxies together, accounting for about 85 per cent of all matter in the universe. The new […]
Νuclear cars

Thorium lasers: The thoroughly plausible idea for nuclear cars Some proposed technological innovations seem so far out that they are easy to reject out of hand. But sometimes, a new idea has a kernel of plausibility. Such is the case with a new project to develop a thorium laser power generation system that its creator […]
What’s the weather like on other planets?
September 7, 2011
Mercury he baby of the Solar system and closest to the Sun, smallest-planet Mercury has no atmosphere, so its weather forecast is usually fairly dull. However, visitors would be advised to either wrap up very warm, or slap on lots of SPF 50, depending on which part of the planet they stop off at – […]
Virial estimator for dark energy
September 7, 2011
A.D. Chernin et al A new estimator of the local density of dark energy is suggested which comes from the virial theorem for non-relativistic gravitating systems embedded in the uniform dark energy background. 1 Introduction The virial theorem of Newtonian mechanics plays a central part in the studies of gravitationally bound quasi-stationary astronomical many-body systems […]
