Galileo in 15th century, discovered that any object falling to earth, fall at the same rate of time . He mentioned that a cannon ball and a feather, if dropped from the same height will touch the ground at the same time provided there is no air resistance. He had difficulty explaining it for quite a long time and also unable to prove it visually.
4 centuries later with the current technology it has been experimentally demonstrated.
Its a super visual treat to watch the video 👌
