Gallileo theory proved with help from NASA & BBC
The video is amazing !!
Galileo, born in Pisa in 1564 and died in Arcetri, near Florence, on January 8, 1642 (77 years old), was a 16th century Italian mathematician, surveyor, physicist and astronomer.
According to Galileo's theory, if you remove the air from a room to create a vacuum and drop feathers and a cannonball into it, both will hit the ground at the same time!
Indeed, according to Galileo, the speed of an object is independent of its mass in a vacuum. In theory it works, but in his time, Galileo could not prove it... it took over 400 years before the experiment could be carried out.
While we all understand and accept his theory, to see it verified is remarkable.
