Light Exists in 2D

At high speeds, Newton's Laws become invalid and the equations of motion change in strange and perplexing ways... Special Relativity and Lorentz Transformations give rise to numerous physical effects. Length Contraction and Time Dilation dilation are but a couple however these are traditionally applied in the setting of objects which have mass travelling at relativistic speeds. Whereas in this video I introduce the concepts and physics necessary to theoretically consider how light (photons or electromagnetic waves) may perceive reality and the Universe. Special Relativity leads to many other interesting thought experiments such as the well documented Twins Paradox and is overall a really fascinating part of modern physics. 0:00 - Introduction and the need for Special Relativity 0:37 - Kinetic Energy, Postulates, Lorentz Factor and Transformations 2:40 - Physical Interpretation and Results of Relativity (Length Contraction / Time Dilation) 3:46 - Nature of Light Speed and how this applies to Photons 5:25 - Zero Length and Time Elapsed leads to 2D perceptions of spacetime
