Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
He's gone crackpot.
So, I guess he's saying that after the heat death of the universe, if you throw away all of your rulers and replace them with much larger ones, and you throw away all your clocks and replace them with much faster ones, the universe looks like it did just after the Big Bang. All those left-over photons look much more energetic and closer together, basically.
Is it really right, though? Don't some constants (or phenomena) not scale with that change of units? Like, are the left-over photons ever likely to make new black holes? If a cesium atom ever forms, isn't it going to oscillate too quickly?
