Question: What is so fascinating about watching objects move?

The way that gravity affects the world is always a pet interest, basically when Galileo said that everything moves to earth at the same time that just bloo my mind. How is this even possible? Basically what he was saying was if we move away from the earth’s gravitation pull all objects would move at the same time. But then roughly at the same time this chap called Newton said what goes up must come down. He come up with an idea of well if i take me gravity and take mass and full it through the air there is something acting on it this become what we know as force. Hence he come up with one of the oldest equations to date Force = Mass X acceleration. This sort of work still goes on now and it’s fantastic
