I’m not a physicist much less an astrophysicist and so take what I’m about to say with a hefty grain of salt. But I wonder if this new approach can also explain observations of distant galaxies. Distant galaxies either redshift because they’re moving away faster over time due to dark energy or redshift because their mass is changing. Can this new theory help explain why older galaxies might lose increasing mass over time?

I thougt the red shift is due to Doppler effect and the universe expansion (planets are running away from any observer in the universe)

>redshift because their mass is changing.

Why would that cause red shift?

[tycho-newman]

Losing energy shifts the frequency of your emissions towards red.

Basically, cooling down is the same thing as moving farther away from an inertial reference point.

Are you thinking of thermal radiation? And what does losing mass have to do with cooling down?

We observe redshift in the spectrum. Hydrogen emits radiation in very specific frequencies, which are redshifted. This cannot be explained by losing mass, heat or energy.
