>>11552921this was controversial because newton refused to treat light as a wave, he assumed it was a massive particle, and since he was the man back in the day, no one listened to huygens when he proposed the nature of light as a wave, and the entire field of optics was held back by this for approx. 150 years...
same with einstein and lasers btw, he refused to believe a system could be held outside of thermal equilibrium, which resulted in lasers being invented only 50 years after the initial theory was proposed.
