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 isnt 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  becomes minus infinity at the cost of making a lot of other things much more complicated Its 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 doesnt lead to simplicity
