Does nature actually abhor anything?

[zoobyshoe]

There's a saying that nature abhors a straight line.

There's no such saying. You are mixing two separate sayings together: 1.) "There are no straight lines in Nature", and 2.) "Nature abhors a vacuum".

 

[Pythagorean]

Nature abhors a change in flux

 

[bp_psy]

Nature abhors giving away free stuff." There ain't no such thing as a free lunch".
