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.
If anyone is wondering how google is doing, it is giving incorrect answers to the query “How old is the Universe?”
Instead of serving up scientific consensus (just shy of 14 billion years) it is latching onto recent media coverage of a questionable study (tired light, time-dependent coupling constants) claiming a much larger figure.
Notably, it gives me the right answer from an incognito window. But elevating popularity metrics over scientific consensus is a real problem!
I think highest/easiest ROI would be devices that alert or avoid bad events.
Computer simulation provides 4,000 scenarios for a climate turnaround. [9300 that don’t]
