Very interesting! It's a little unsettling to think that coupling constants can change over time, though. I'm looking forward to possible explanations of how and why that happens.

"constants"
Is this related to the recent articles about how the "speed of the passing of time" has actually changed over time? Not sure if I understood all that correctly but I remember wondering if it was going to mess with carbon dating and estimates of the age of the universe
that is a very big difference
It is certainly a bold and interesting claim. Lets see if it pans out.

Tired light theory requires:
Distant galaxies to be blurry (they aren’t)
Events in faraway galaxies to happen at the same pace as nearby events (they don’t. Time is dialated just like frequency is redshifted)
Cosmic background radiation would not be a black body
Constants c, G, and hbar would change through the history of the universe.
