Bryan Enderle, a wonderful science professor at UC Davis, was kind enough to give me some feedback on my work which prompted me to come up with a Nutshell Version. In fact, this is something I should have done to begin with. Who wants 10,000 or 20,000 words? Let me give you this whole hypothesis in a few paragraphs.
I believe the speed of light is actually zero. The world we observe with our senses is emergent, and it is light from which it is emerging. The degree of emergence is reflected in the speed of light. The farther backward in time we are, the faster light’s speed.
But why, then, does light’s speed not perceptibly change? Because time’s speed is changing proportionately. At the Big Bang, light’s speed is c, and time’s speed is zero. At the End of Time, light’s speed is zero, and time’s speed is c. Light and time are trading places.
As time speeds up, light slows down. Or, as time slows down, light speeds up. Though there is an “End of Time,” it is merely the point of reversal. Time never ends.
We do not perceive light’s speed changing, because our sight is unable to distinguish between a train traveling at speed c, and a train traveling at speed zero on a track that is traveling at speed c. We speak of the universe as accelerating, yet we do not take its movement into account, in our equations. This is not an inertial frame.
This PBS Space Time video explains what I mean by “inertial frame.” Einstein asked “What if gravity is fake?” I echo him, and ask: “What if gravity is fake, and the speed of light is inversely proportionate to the speed of time?”
