The speed of light changed recently - New experiments in Oklo reactor in West Africa have shown that a fundamental constant of the nature (alpha) has changed recently; this consists of the ‘c’ term. So, the speed of light may have changed recently. Visit this site - www.newscientist.com (click here) for further reading.

New form of loop quantum gravity arrives - this new form says that particles are made up of tangles in space. Finally, theory has obtained a generalization of all particles like string theory but without any use of background space.

Quantum gravitation states - For the first time, physicists have observed quantum states which are quantized under the effect of the gravitational field. The vertical motion of ultracold neutrons comes in quantized size. Visit this site - http://www.aip.org/pnu/2002/573.html (click here).

Physicists have found ways to see extra dimension - They can now make a model of extra dimensions by studying the pattern of cosmic energy emitted during big bang - a model based on the Superstring theory.

Dark matter no longer present - Physicists have developed a new model in which behaviour of gravity becomes a bit different at cosmological level leading to the acceleration of the universe. This model does not need a dark matter presence. Visit this site - http://physicsworld.com/cws/article/news/24139 (click here).

Measurement paradox - A new paper by Prof. Lawrence Krauss (Prof. of Astronomy, Case Western Reserve University) suggests that the observation of dark matter may affect the age of the universe.
