Hopefully, people will soon leave their biaises and treat Earth physics the same way as other physics application, i.e. with objectivity.
Many years ago, I had to leave this forum because of that problem (lack of...
I'm mostly trained as a physicist, so I'm wondering, on a scale from crackpot (1) to imressive (9), where does this hypothesis rank to an anthropologist?

I was once mystified by time. Now I see it as nothing but counting something mechanical.
Take a reference motion, such as the Earth rotation, and all of the "t"'s in physics equations could be replaced with "number of Earth rotations".
Instead of "distance over time", speed could be defined as...
I'm interested in standard curriculum textbooks on micro- and macroeconomics. No holding back on math rigour please, I get annoyed by the law of demand presented as a straight line.
All of math could be written in a spoken language. It's actually precision shorthand for surprisingly long sentences. Try reading Newton's Principia, you'll appreciate the current notation.
You could actually make two cups and do the experiement. Drop a thermometer in each, and clench only one. My hunch is that the clenched one cools faster.
Yes to temperature widening the spectral lines! Especially temperature I believe!
Dark line because emission can happen in any direction other than towards your eyes!
