Part 2/8:
The story of time begins with Sir Isaac Newton, who, following a legendary encounter with an apple, posited that time was absolute, flowing uniformly across the universe. He believed that time for someone on Earth would pass at the same rate as for someone in deep space. For generations, this perspective sufficed as a reliable framework for understanding motion and gravity.
However, Newton's theories couldn’t fully explain the gravitational interactions among distant celestial bodies. It wasn't until the early 20th century that Albert Einstein revolutionized our comprehension of time. Through his theories of special and general relativity, he established that time is relative, dependent not only on motion but also on gravitational influence.
