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).
