Alphonsus Kelly, an Ireland engineer, in his
lecture at Trinity College, Dublin, on February 15, 1996, stated that the
Einstein’s Relativity theory might be wrong. Kelly revealed the experiment of Sagnac,
the French physicist in the year 1914, showing that the time taken by a light
to complete one rotation is found to be different from the time taken by one
rotation in opposite direction. The Sagnac’s experiment proved that the speed
of light was not constant. It is different from Einstein’s teory stating that
the light velocity is constant.
