I mondi di Galileo – Galileo’s Gravity and the Origin

Gravity is full of surprises. Including the fact, discovered by Galileo, that all objects fall at the same speed, regardless of their mass, form or composition. Since then a whole series of surprising discoveries has been made including the fact that gravity can increase or diminish the volume of space or cause objects to appear to be travelling at a speed faster than light. It is an infinite source of energy and can even create something from nothing. These are all properties that can be explained and that play a crucial role in current ideas on the origin and evolution of the universe.
