Stephen Hawking, who unraveled the mysteries of black holes and inspired billions of people, left behind some remarkable insights before he died on March 14.
Hawking was a theoretical physicist who pioneered new understandings of black holes and the cosmos at large. What's more, he did so while struggling with a severe neurodegenerative disease that confined him to a wheelchair for the vast majority of his life.
The world-renowned scientist carefully contemplated and composed his thoughts with a special eye-tracking computer, and those words — many of them humorous — continue to inspire generations of people who were curious about how the universe works, where it came from, and where it may be headed.
