The laws of physics that govern our universe have left scientists with a lot of questions. But what if there was a simpler way to look at the universe? 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?
