This phenomenon f suppression by religious institutions has been there right from the beginning but in spite of that things are changing ! To day we are travelling in space where as flying i the air was a dream some hundred plus, years back! There was no electricity, no nuclear bombs, No TVs etc. When the train was introduced for the first time people , they were hiding in their houses thinking that train is a devil, but then today it has become indispensable part of Human life! Thus though the religious institutions may try to suppress the changes brought by the science, if these changes are good for the society and human progress, no body can stop them in implementing! Thanks !
