Is There Gravity in Space

The video explores the concept of gravity, debunking the myth that space is devoid of it. It explains how gravity is essential for the formation of galaxies and planets, and how it operates according to Newton's equation, which involves the masses of two objects and the distance between them. The video also clarifies the concept of orbit, describing how astronauts experience weightlessness not because there is no gravity, but because they are in free fall around the Earth. Finally, it emphasizes that gravity is a universal force, constantly acting on all objects, no matter how far apart they are.
