Dear Prof. Dr. Stephon Alexander:

You may remember two years ago, when I wrote that you were the first person in physics who at least acknowledged that logically this universe starts either super hot at the Planck Temperature or superconductingly cold at zero temperature. Of those choices, I had chosen to explore the cold start.

We haven’t progressed terribly far from that point, yet you might enjoy reading the latest work. And, of course, your comments will always be welcomed. Please be just as pointed as you can be!

Now, I haven’t forgotten that I owe you a session at Snug Harbor, New Orleans with your fellow jazz artist, Donald Harrison with an audience of fellow physicists from around the city, all accompanied by one of their jazz aficionados. It’ll be quite a night. We’ll make it happen.

Warm regards,

Thank you, Stephon and Laura!

I’ve gone through your September 1, 2017 article and have highlighted several spots, particularly “We are exploring the possibility of an underlying microphysical mechanism that limit contributions to vacuum energy from phase transitions in the early universe, and furthermore which relates the energy of the vacuum to the coupling constants of nature and their hierarchy, in other words to the the Standard Model, in a fundamental way…”

In the microphysical scale, if you begin at the Planck units and use base-2, you’ll have those 64-to-67 doublings to the CERN scale which define the very-very early universe. Between the 143rd and 144th doubling the universe is just a second old and the length is the distance light travels in a second. At the 197th we are within our first 500 million years and at the 202 we are now emergent within the Age of the Universe today.

That simple math and simple logic, of course, is too simple for most. You may be surprised, once you are inside those domains, how complex and open it all is.

Thanks again for your article.
Wonderful collaboration!

Most sincerely,

Dear Prof. Dr. Stephon Alexander:

Let’s improvise! It looks like I’ll be quoting you more than not!

I have now listened to you play and tell your story about your dear Mr. Kaplan. I have surveyed your website. Hardly irrational thinking; it is meta-rational. Can you hear the harmony of the spheres? Love your rhythm and harmony comments.

Now, I was on your website (wonderful site, thank you) and on it I sent this note through your



“Wow, how very impressive. When you come to New Orleans,  please let me know. My wife and I would love to hear you play live!  Can we get you booked into Snug Harbor, one of our many jazz clubs?”

Now, for those special words of yours that I would like to quote:
“Alexander described two potential ways the universe began. Either it was at the Planck temperature and then inflated and cooled to create what we see today. Or it started off at zero temperature and speeded up as it expanded. So one of two situations could have happened,” he said, “and it would be interesting if, indeed, both situations are really the same underlying phenomenon.”

You are the first person I have found who said the “either-or” on temperature. Do you have colleagues who are so open?  Also, I would like to credit the source for that quote if it was from one of your publications.  I am looking for it now.  Thanks

I am now surveying your ArXiv submissions.  Have you ever thought that the old CMBR can be achieved within your OR suggestion?  Here’s one way to do it:

Thanks again for all that you do (and I thank Mr. Kaplan, too!).
