Chapter 1-4: Rethinking General Relativity as 5 Dimensions of Physics - A Unifying Theory of Gravity
Many scientists have postulated that we need more dimensions to explain our observations in physics. The problem has been "Where are they?" This is my proposal of a different way of thinking about dimensions so we can perceive them, measure them, and incorporate them into our understanding of physics.
For this video, I focus on a fifth dimension of space and General Relativity. Below is a chapter outline of the video so you can skip around as needed, and at the bottom here is a list of videos I reference for further education.
A special "thank you" to my daughter who has spent the last 8 months diligently helping me put this together with editing, animations, and a lot of insight and feedback (she makes a few cameo appearances).
