The Maxwell Equations and the Universe

The universe expands and expands exponential expansion. The black holes will all evaporate the way by walking evaporation. They'll swallow galactic clusters. What's left in the universe? Very well photons. Now giving the simplified version of the theory because there's some questions about it still. But let's say it's dominated by photons, which is pretty well true, but not. Let's take that. Okay. Who's in this universe eventually? Not us. Because more importantly, the equations governing light are the wonderful equations due to James Clark Maxwell, the Maxwell equations. And they have a very interesting property that they can't tell big from small. If you want to build a clock,
