🔭 Recommendation: “Doppler vs. Kepler” by Steven Sesselmann

As someone who has spent a lot of time thinking about the role of potential, reference frames, and how we observemotion in the universe, I found Steven Sesselmann’s paper “Doppler vs. Kepler” to be a breath of fresh air.

Rather than accepting the longstanding mystery of “flat galaxy rotation curves” as a call for dark matter or modified gravity, Steven steps back and asks a simpler question:

Are we interpreting the measurements correctly?

This paper:

• Clearly outlines the difference between Doppler-based observations (line-of-sight velocity) and Keplerian motion (inferred from a fixed celestial sphere),
• Points out the mismatch in fiducial reference points that could explain the discrepancy,
• Shows how a simple sign correction, with no new physics, produces rotation curves that match observation,
• All while staying within classical Newtonian dynamics.

It’s the kind of elegant, intuitive thinking that makes you pause and say:

“Wait… why aren’t more people talking about this?”

If you’re curious about galaxy dynamics, observational bias, or the power of questioning the frame itself — I strongly recommend giving this short but sharp paper a read.

It doesn’t require complex math or exotic matter — just a willingness to look at the sky with fresh eyes.
