This article started with what you might call boredom. I find E=mc^2 absolutely fascinating. But we’ve all seen it in that form plenty of times. We’ve even seen it plenty of times as m=E/c^2 (in the form where the equation is solved for mass). So I thought I’d play around with c^2=E/m (obtained by dividing both sides of E=mc^2 by m) and other forms, and see if they were related to the ideas I’ve been having in the last few years. For example, dividing both sides of m=E/c^2 by E means c^2=m/E, so E/m=m/E and mass-energy equivalence emerges (and I plan to explore a few other partial forms of the equation). My keyboard was soon producing sentences about the speed of light, division by zero, “digital” string theory, repelling gravity and its apparent attraction, dark energy, a higher dimension, computer simulation, the universe and subuniverses (with the demise of both the Big Bang and inflationary cosmology), the Law of Conservation of Mass-Energy, imaginary numbers, hidden variables, quantum fluctuation, mass and masslessness, time dilation, unification of the fundamental forces, cosmic microwave background (addressing clumpiness and temperature concerns preventing its dissociation from the big bang), intergalactic and time travel, retrocausality and quantum/macroscopic entanglement. I don’t know how all this appears to anyone else – but for myself, E=mc^2 gives me confidence that my extremely unusual ideas aren’t fantasy but belong to the real world.
