I just read that paper about scaling space and time. It is even dafter than the ones in Physics Essays. At least the Physics Essays ons just try and do their stuff and leave out the problems like the decay rate of supernovas. That scaling one has us shrinking instead of the universe expanding and then says the density remains the same - however they forget that what matters is what we see and the density has decreased from our point of view so it isn't the same through time. I sympathize that the idea of a big bang is difficult but the scaling paper does not get round it, at best it just gets the log of time so 0 becomes minus infinity at the cost of making a lot of other things much more complicated. It's like saying the earth must be fixed and treating the rest of the universe as rotating round us every twenty four hours. It can be done but it doesn't lead to simplicity.
