Now, if you’re like me, you might think that gravity has always been a constant force in our lives but let’s take a step back and explore how people used to understand this concept before Sir Isaac Newton came along with his fancy equations.

First off, the ancient Greeks. They believed that everything in the universe was made up of tiny particles called atoms, which were constantly moving around and colliding with each other. When these atoms collided, they would sometimes stick together to form larger objects like rocks or trees or even humans!

But here’s where things get interesting: according to Greek philosophy, there was a force that kept all of these particles from flying off into space. This force was called “earth-love” (or “geocentric attraction,” if you prefer). It was believed that the earth had this special power because it was made up of more atoms than any other object in the universe and therefore, it could attract other objects to itself with greater strength.

Now, let’s fast forward a few centuries to medieval Europe. During this time period, people started to think about gravity as something that was related to weight. For example, if you dropped two different-sized rocks from the same height, they would hit the ground at the same time because heavier objects had more “gravity” pulling them down towards the earth.

But here’s where things get even more interesting: some people started to believe that gravity was actually a force that came from within the object itself! They called this idea “impetus theory,” and it basically said that every time an object moved, it lost some of its internal “gravity” which is why heavier objects would eventually come to rest.

But don’t worry we’ve come a long way since then, thanks to the geniuses who came after them.
