“We Lied to you About Gravity” – Michio Kaku

First of all, we have the theory of gravity. Gravity keeps you on this floor. It attracts everything around its vicinity to create gravity around the earth, or as we say in our astronomy courses, “Gravity sucks.” Gravity pulls everything to the center evenly.

But then, Einstein gave us a different picture. Gravity doesn’t suck at all. We tell our students, “We lied to you.” Gravity does not pull you to the floor. Space pushes you down.

Why are you sitting in your chair today? Does gravity pull you to the floor? No, there is no such thing as gravitational pull. We lied to you. The space around you is warped, and space itself is pushing you down into your chair. That’s why you’re sitting in your chair today.
