Because they are separated from the rest of the world
The one which describes a difference between Robert Boyle and Isaac Newton is that, Robert Boyle discovered the relationship between pressure and gas volumes, while Newton discovered the law of gravity.
It is said that in the mid-1600s, Robert Boyle considered the connection between the pressure p and the volume V of a confined gas which was held at a constant temperature. Thus, through this, Boyle saw that the result of the pressure and volume are said to be seen almost steady.
Whereas, Isaac Newton is said to have clarified the operations of the universe through Mathematics. Thus, he depicted the law of gravity and motion. Thus, these laws are math recipes which clarify that how protests move when a power follows upon them.
Hence, gravity is the power that makes the things fall down.
