Planet Capable of Supporting Life Found



The planet exists outside our solar system and lies in a 'habitable zone', meaning that it isn't too near to its sun to dry out or too far away to be frozen. The planet, Gliese 667Cc, orbits around a red dwarf star (common stars in the neighbourhood of the sun, usually hosting planets called gas giants, which are not composed of rock matter), 22 light years away from the earth. Gliese 667Cc is a solid planet with roughly four and a half times the mass of Earth and receives less that ten percent less light from its red dwarf star than the Earth gets from the sun. The planet still receives nearly the same amount of energy as the Earth, which means that water could be liquid and surface temperatures could be similar to that on Earth.

Scientist Who Was Out to Challenge Einstein's Special Theory of Relativity Resigns After His Findings Were Overturned


Antonio Ereditato, an Italian professor who led an experiment to challenge one of the fundamentals of modern physics by showing particles moving faster than the speed of light, has resigned after the finding was overturned earlier this month. 
The OPERA experiment (as it is known as) measuring the speed at which sub-atomic particles called neutrinos travelled from the European Organization for Nuclear Research (popularly known as CERN) research centre in Geneva to Gran Sasso in central Italy at first appeared to show they had flown the 730 km stretch 60 bilionths of a second faster than light placing the speed at 4.38 * 10^ 16 metres per second compared to that of light which is 3 * 10^ 8 metres per second. Had it been confirmed, the finding would have disproved Einstein's 1905 Special Theory of Relativity, one of the foundations of modern physics and cosmology, which holds that nothing in the universe can travel faster than light.
The result of the experiment was later called into question by separate experiments and CERN said the OPERA result appeared to be the result of a measurement error or malfunction.
Sorry Professor Antonio, but you can't disprove Baba Einstein that easily.
