Interessanter Blog mit einigen Anknüpfungspunkten. Dilworth ist wohl auch der Bewegung ‚Skeptischer Rationalisten‘ (als einem Versuch der Rettung von Wissenschaftlichkeit) verbunden.
David Dilworth bringt hier einiges gut auf den Punkt in Sachen Missbrauch der Mathematik in der Physik. Auch eine gute Diskussion im Anschluss im Forum.
Im Artikel taucht der Verweis auf folgende Arbeit zu möglichen Interpretationen der ‚Rotverschiebung‘ des ‚Licht-Spektrums entfernter Himmelskörper‘ auf:

„However the cosmology implied by general relativity was never completely accepted by Hubble. In a series of lectures he gave in 1936, he explains that “the familiar [Doppler] interpretation of red-shifts seems to imply a strange and dubious universe, very young and very small” . Today, the universe is estimated to be ten times larger and older than Hubble’s universe and the cosmological red-shift is explained by the expansion of space.
Even then, the mechanism behind many red-shift observations remains unclear — the expansion of space does not explain the solar limb red-shift, the “K-effect”, compact groups of galaxies with one discordant red-shift member, intrinsic red-shifts of quasars, quantization of red-shifts, alignments of galaxies showing the “Finger of God”, and the high degree of uniformity of the CMB radiation. As a result of these anomalous observations, many mechanisms and models have been proposed in an attempt to provide an explanation. Some of these mechanisms are based on an idea similar to Zwicky’s while others are based on the Doppler red-shift, space expansion, a Big Bang scenario and even ’new physics’.
The present paper lists most of these hypotheses and attempts to provide quantitative comparisons between the many possibilities. The main focus of this paper is to extend an earlier review of red-shift mechanisms which are a function of the cosmological distance to the observed objects. Other red-shift mechanisms, not necessarily related to distance, are given a short description at the end of the paper. They may explain, for example, intrinsic red-shifts observed in quasars.
The red-shift mechanisms are classified under seven categories based on how space, time, matter and light combine to produce the red-shift:
1. A time-dependent distance or metric of space,
2. a time-dependent property of gravity,
3. a time-dependent property of matter,
4. a time-dependent property of light or an interaction of light with itself,
5. a time-independent geometry of space and time,
6. a time-independent property of a field, gravitational or other,
7. an interaction between light and matter.
Because of the wide range of conditions under which red-shifts are observed in astronomy, it is likely that more than one mechanism is at play.“
