Just finished watching (twice) "Einstein's Blunder" on Netflix. If you haven't seen it, it's a dumbed-down (e.g. even *I* almost grasped it) review of more recent Variable Speed of Light (VSL) theories. As I'm watching this, it occurs to me that the OTU has likely adopted one or another of these as valid, since VSL allows energy and matter to be created/destroyed and also includes repulsive gravity as a fundamental force.

Of course, not that many real world scientists support VSL, but it appears to solve a lot of basic problems. 

[As I understand it, while the speed of light varies over time, the scale of time involved is so massive relative to the change in velocity that - for all practical purposes for us living people - the speed of light is effectively constant.]
