Is Gravity An Illusion?
Season 1
Episode 17
Most of us take gravity as an assumed part of our living realities, but why? Basic physics introduces us to the concept of gravity from a Newtonian sense, but when you start factoring Einstein into an understanding of gravity, things get weird. For example, gravity may simply not exist. Why? Watch this week’s episode of PBS Space Time and find out why gravity may be an illusion!
