### Fluctuations at the threshold of classical cosmology

- Physics
- 1970

It is proposed that the initial conditions of galaxy formation are metric fluctuations at the threshold epoch of classical cosmology, and the evidence in favor of this theory is (i) the density fluctuation obeys the n=23 rule, and (ii) the spin fluctuation gives an eventual angular momentum of the order N43ℏ, in reasonable agrement with that of the Galaxy.
