Abstract
The question 'It from Bit' or vice versa is the question of what is real. The answer is a matter of belief, so I analyze why physicists believe theories, including QED and QCD and follow with the simplest possible theory of the real world. I focus on the fact that gravity is real, and discuss a new approach to non-linearity. Because Wheeler’s 'It from Bit' is tied to his 'Participatory Universe' I explore that topic and a theory of information based on gravity.
