"The answer may be that other regions of the Universe are not quite so favourable for life as we know it, and that the laws of physics we measure in our part of the Universe are merely ‘local by-laws', in which case it is no particular surprise to find life here."
John Webb -University of New South Wales 
One of the most cherished principles in science - the constancy of physics - may not be true, according to new research carried out at the University of New South Wales (UNSW), Swinburne University of Technology and the University of Cambridge.
The study found that one of the four known fundamental forces, electromagnetism - measured by the so-called fine-structure constant and denoted by the symbol ‘alpha' - seems to vary across the Universe.
