‘PBS Space Time’ Explores Whether Gravity Is an Illusion

PBS Space Time host Gabe Perez-Giz explores whether gravity is an illusion is a recent episode of the series. The explanation is a bit complicated, but makes a number of interesting points about frames of reference, acceleration, and even touches on general relativity.

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.
