One of the biggest accomplishments through his life. one of them was done over 100 years ago. Albert Einstein grappled with the implications of his revolutionary theory of relativity and came to a startling conclusion. He found out that mass and energy are one, related by E = mc2. In "Einstein's Big Idea, there were two main parts. First, Einstein discovered that the speed of light is constant. Secondly, Einstein determined that space and time are not absolutes; rather, they are relative to the position of the observer. So if you watch how fast something is going it might seem different from another person who is in a different position.
