2. Now for our second story.
Subject: Relativity.
In shaping modern cosmology, Galileo articulated the relativity principle in 1632, Newton made gravity universal in 1687, and Einstein revealed gravity as the curvature of spacetime in 1915.
Galileo Galilei showed that constant motion is undetectable. That physics works the same on a smooth ship or solid ground. Isaac Newton made gravity universal. Centuries later, Albert Einstein extended Galileo’s insight. Einstein revealed that space and time are intertwined. Energy is matter, and gravity is the very fabric of spacetime itself.
