Dear Charles:

Indeterminacy. Chaos. Free will. Ego. Arrogance. And then, it gets worse! We are all so prone to error, it is a small miracle that we get things done correctly at all.

Quick question: Do you know anybody who is working to define a grid from the Planck base units (or the Stoney units or other yet-to-be-defined primordial units) to the wave-particle duality or quantum fluctuations?

Do you think it is a reasonable task to undertake? Thanks.

RE: Shouldn’t we asking, “What is time?” when it all feels like yesterday.

Hi Charles,

The internet brings us all together in the most elusive and direct ways. Given all your strengths — PhD in X-ray astronomy from the University of Cambridge in 1988 — you might enjoy a little thought experiment:

“If we take the Planck base units, and multiply them by 2, over and over again, how many steps would it take to get to the current moment in time (assuming Planck Time is the first moment in time)?”

Answer: 202 notations or doublings See the numbers here:

Might it help to know that the universe is just about 436,117,076,640,000,000± seconds old? It is a rather peculiar notion that the age of the universe can be computed in seconds. Might it help to know that the first second falls between Notations 143 and 144?

Yes, we mapped the universe in 202 base-2 notations (doublings) in a high school geometry class. It was a result of playing with embedded geometries and by asking Zeno’s question. We didn’t know what we didn’t know.

That Planck scale has not been explored enough!

We started our explorations back in 2011. That horizontally-scrolled chart emerged in 2016. Nobody has debunked that little chart, even after repeated requests of some of our finest scholars!

I hope you are intrigued enough to take a look. Why does the logic and math look so straightforward but it is all summarily ignored?
