Speed of light issues have often moved sections of religious people in rather strange ways. Way back in 1973, as a young physics lecturer at Quaid-i-Azam University, I had been fascinated by the calculation done by the head of our department. Seeking the grand synthesis of science and faith, this pious gentleman — who left on his final journey last month — had published calculations that proved Heaven (jannat) was running away from Earth at one centimeter per second less than the speed of light. His reasoning centred around a particular verse of the Holy Quran that states worship on the night of Lailat-ul-Qadr(Night of Revelation) is equivalent to a thousand nights of ordinary worship. Indeed, if you input the factor of 1,000 into Einstein’s famous formula for time dilatation, this yields a number: one centimeter per second less than the speed of light!
These days the internet groans under the weight of claims that the Holy Quran had specified the speed of light 1400 years ago. Dr Mansour Hassab El Naby, said to be a physicist from Egypt, announces that according to his Quranic calculations, this speed is 299,792.5 kilometres per second. He even gives error bars! Another video gives a still more precise figure of 299792.458 km/sec. Given the unrestrained leaps of logic made by the authors, it is not surprising that they all arrive at more or less the same numbers. More:
