Dear Prof. Dr. Edward Kolb:

In the 7 September 2020 ArXiv article, *Completely Dark Photons*… you say, “…we calculate the number density of particles resulting from gravitational particle production (GPP) during inflation…” we may be better served to look at Planck Time — 5.391 16(13)×10^{-44} seconds — and other base units and to apply base-2 as the most simple expansion, what would expand? …preons (Jogesh Pati and Abdus Salam in 1974)? …geons (Wheeler, 1955), …strings, automorphic forms, information (ZFC, axiomatic set theory, etc). How about return to Lemaitre’s primordial sphere? If such a sphere manifests, defined by the Planck base units, *it would be a variable, but perhaps around* 539+ tredecillion spheres per second.*

Too idiosyncratic to pursue?

Thank you.

Most sincerely,

Bruce

Dear Prof. Dr. Dean Edward (Rocky) Kolb:

I first found your 1998 work through an “Inflation” search —

inflation + CBR fluctuations + Hubble radius See result #4.

https://ned.ipac.caltech.edu/level5/Kolb/Kolb3.html

I wondered, “Who wrote this page and when?”

By clicking on “Contents” I found you and your 1998 Fermi-work overview:

https://ned.ipac.caltech.edu/level5/Kolb/Kolb_contents.html

Then, of course, I explored your more recent pages:

• https://astro.uchicago.edu/~rocky/cv.pdf

• https://astro.uchicago.edu/~rocky/

• https://kicp.uchicago.edu/people/profile/edward_kolb.html

What a progression from the University of New Orleans!

Congratulations. Entirely remarkable and spirited career.

We lived in NOLA for eight years (Remember JT Curtis? High school football?)

Most recently I have quickly paged through your presentation

on dark matter from 2010:

http://kicp-courses.uchicago.edu/2010-dark/talks/kolb_lecture-3.pdf

**My questions for you**:

1. Do you believe in an infinitely hot big bang?

2. Did Lemaitre initially postulate a cold start of the universe?

3. Do you think the Planck units are real?

4. Might Planck time be the real beginning of the universe?

Thanks.

Warmly,

Bruce
