A method that takes into account the speed of light, time dilation, redshift, dark energy and an expanding universe? My brother, Jon, has come up with just such a hypothesis for a unified theory of everything that could explain all these and more. The biggest question is - could he be right? ▀▀▀▀▀▀ 0:00 A Theory of Everything 3:25 Time Is Relative 6:32 Do We Need Dark Energy? 12:26 4D Spacetime 17:22 Speed Limit of a Photon 22:38 Calculating the Speed of Light 26:42 Why Does the Universe Expand 29:20 The Barn Pole Experiment 35:12 Solving the Antimatter Problem 37:14 Is Time Travel Possible? 39:17 Does Free Will Exist? 41:03 Vibrating Strings ▀▀▀▀▀▀ Astrum books are still available in the US!
