Needs of Nature According to Shu

``For this we argue as follows: When converting the magnitude of increment in time, dt , into that in length, Nature needs a universal standard to refer to.  Noting that the concept of time arises from the observation that the distribution of mass-energy contained in the universe is dynamic and the rate of change, $\dot \rho(t)$, of the cosmological density is the very quantity that manifests the dynamicity of a homogeneous universe, we postulate that $\dot \rho(t)$ is the standard taken by Nature. If the distribution was static, $\dot \rho(t)$ $0$ , the concept of time would have no meaning.''

Shu, somehow thinks that Nature has needs. I know the game, I play it myself, I feel though; that we can step back a little bit, and see what  we are saying.

The game is this: he gives a prediction that goes well with Filippenko et al.'s measurements. So, maybe Shu is right.

BTW, I notice in his references that Perlmutter et al. is first, even though his paper came later than Riess et al.; mh.
