Thanks for this thread, as it was on my mind too as I begin my investigation of RS/RS2.

As a follow-up question, how might it be possible to distinguish between inward and outward angular motion? Linear is easily understood... speed of light outward separation of galaxies vs inward "pull" of gravity, but I can't visualize a similar differentiator for angular motion.

Cheers!

RS2-0: Getting Started with the Reciprocal System • Re: Newbie - where to start?

RS2 Research - Mon, 01/09/2017 - 14:21
Hi guys. Long time listener, first time caller. Well, not really... just wanted to say that.

I just discovered all this a few weeks ago and have been trying to work my way through Nothing but Motion, with supplements here and there from Bruce's tutorials. Dr. Larson's writing is thick and difficult to follow, and doesn't help the fact that RS is supposed to be a simpler way to think about the universe.

Anyway, I'm about to start chapter 13 ("Physical Constants"). After spending considerable effort to understand a photon, that a photon is the center of an atom (actually, two photons), and the complexities of the rotational motion the units must undertake in previous chapters. After pausing to supplement that understanding with information here, I find that RS2 has scrapped the idea of a photon being a simple oscillation, and the idea of needing "something to rotate" in order to build a particle of matter. Are there more major contradictions to come? Is it worth moving forward, or should I switch to a different source?

Also, in chapter 12, I came across a statement where Larson up and says, "...there can be no physical distance less than one natural unit, which, as we will see in the next chapter, is 4.56 x 10-6 cm," before saying something about measured distances being smaller. Is this still considered current or correct? Having a background in biology/pathology, there's no way 45nm could be unit size, evidenced by electron micrograph images like the one below. Everything else seems so elegant, so hopefully you guys can enlighten me or show me what I misunderstood?

How much of you lies among the stars? How are the elements that make up life distributed among stars and planets? As trippy as the questions seem, astronomers from the Sloan Digital Sky Survey (SDSS) announced today at the 229th meeting of the American Astronomical Society that they knew the answers — or, at least, were starting to learn them. SDSS, “the energizer bunny of sky surveys,” according to spokesperson Karen Masters, is a massive data collection project that’s
