Indeed. In fact, I think we're long overdue.
On an earlier post you wrote, in reply to PatrickHenry: "The 'rod' only represents the trajectory of the particle over time. The particle is pointlike and massless. The particle moves through the space as a massless object. The shadow of the particle on the plane moves on the plane as if it had mass."
Fascinating insight, Physicist. It seems the "billiard ball [mechanical] model" of the Universe is increasing shown to be an inadequate explanation.... Thank you so much for writing.
I'm sure you will recognize the Wesson article. His consortium has a track record of questioning the presupposition of Kaluza-Klein compactification of the extra dimensions. I find that particularly refreshing.
