When Gravity is nullified by Universal Shadow and Perpendicularity

We have been studying the human anatomy and physiology. In this study we observed that the human body works by four main natural facts: Pressure, Vacuum, Perpendicularity, and Electrochemical energy without the need for gravitational force. Therefore, naturally a hypothesis comes up: gravity does not exist. So what is the alternative? We studied Pressure, Vacuum, and Light. By experiment, we proved that Shadow and Perpendicularity replace Gravity. These findings, we hope, pave a way towards light-shadow technology especially if we can save digits in shadow and exploit the light-shadow dynamics. In our next work we will describe Darkness, White Shadow, Black Shadow, Light, and Energy.
