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.

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. Visit this site - http://www.newscientist.com/article/mg19125642.900.html
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
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
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. Visit
