Did You Know?
"Brings me down" means both causing disappointment and the downward pull of gravity! Sir Isaac Newton discovered gravity around 1666 after observing a falling apple. Gravity is one of the four fundamental forces of nature. Earth's gravity pulls everything toward its center at 9.8 meters per second squared. Gravity keeps planets in orbit around the sun and the moon orbiting Earth. Without gravity, atmosphere would escape into space making life impossible. Einstein's theory of general relativity describes gravity as curved spacetime!
