The idea that the laws of physics remain constant across the universe is arguably a very important and universal concept in Physics. In fact in the case of the gravitational force this has been specifically stated in Einstein’s equivalence principle.

Recently experiments seem to enforce the idea that is not the case certainly for the fine structure constant (alpha). The first hints for a variability of alpha came from analysing observations of the Keck Observatory, in Hawaii. The new data from  the European Southern Observatory’s ‘Very Large Telescope’ in Chile was analysed by Professor Webb and others. He comments:
