AE’s explanation rested “on an ever-present internal energy ... reflected as temperature”.
Physicists were skeptical over “questionable theoretical leaps”.
The Theory fails to match modern observations in at least three scenarios:
It is good to look back on how understanding developes. I am sure I would have made the same objections.
