Dear Prof. Dr. Anthony Aguirre:

Thank you for all your work; I’m tackling the above cited articles and your work within ArXiv.

Our high school geometry class went off on a wild tangent a few years ago. We decided Newton was wrong* and that Leibniz was going in the right direction, and Planck’s base units should not be ignored.**

We applied base-2 exponentiation, simple doublings of the Planck units; and in 202 notations we had this all-natural, simple inflation from a very cold start. The numbers stretched our imagination. Do you think there is enough cogency to continue this admittedly entirely idiosyncratic study?

Your comments would be highly regarded. Are we just too naive for words?


Most sincerely,
Bruce Camber
*Tegmark wants to throw infinity out and Nima Arkani-Hamed wants to retire space and time.
**Big bang theory ignores all but temperature but temperature is always derivative.

    1. By 1927, Georges Lemaitre had attempted to understand the origin of atoms in nature by proposing that before the expansion of the universe started there existed a primeval atom consisting of all the matter in the universe crushed to nuclear densities. It formed a gigantic ball of nuclear liquid which existed in this state at very low temperature. The low temperatures were required to keep this cosmic atom from falling apart via thermal agitation. But this fluid broke-up anyway under mechanical instabilities, into a mist of microscopic particles. He estimated that only 260 binary divisions would be needed to convert the cosmic mass into atom-sized particles. This idea was pursued by Maria Meyer and Edwin Teller, but ultimately this idea couldn’t explain why the universe should expand, or where the light elements came from.
    2. “…if matter existed as a single atomic nucleus, it makes no sense to speak of space and time in connection with this atom. Space and time are statistical notions that apply to an assembly of a great number of individual elements; they were meaningless notions, therefore, at the instant of first disintegration of the primeval atom…”   — Georges Lemaitre

    3. A variant on Lemaitre’s cosmology was proposed in 1966 by David Layzer, developed a short-lived alternate to Hot Big Bang cosmology by proposing that the initial state was near absolute zero. The motivation for proposing such an initial state, reminiscent of Lemaitre’s initial state. Through thermodynamic arguments, Layzer argued that rather than the universe starting in a high entropy state, it began in a very low entropy state near Absolute Zero. It was matter-dominated with little free radiation, and the conditions were favorable for the formation of galaxies via fragmentation. The famous Cosmic Microwave Background Radiation discovered by Arno Penzias and Robert Wilson in 1965 was produced much later when galaxies were forming in a dusty environment.
