There’s a tiny acceleration scale that keeps showing up when we look at how stars orbit in galaxies. In our framework (Quantum Traction Theory, QTT), this same number can be written seven different ways—from the Hubble expansion to a Planck-scale tick of time. Here’s the idea in plain English, and a teaser for what’s coming next as seventh part in the upcoming update to the book.
The galactic “knee” (the acceleration where galaxy rotation curves change behavior) can be written as:

The short story: the same galactic number can be read as:
- a slice of the Hubble expansion (
c H/2π); - a per-turn pace of cosmic time (
c/(2π T)); - a balance with the mass enclosed by the observable universe;
- and even a ratio involving Planck-scale quantities (the tiniest meaningful length/time).
That last “= ?” is our cliffhanger—we’ll unpack that mystery in the next version of the book!
