Full Idea
If a theory has to rely on excessive 'fine-tuning', a series of extremely unlikely events in order to produce the universe we see around us, then it is extremely unlikely that this theory is correct.
Gist of Idea
If a cosmic theory relies a great deal on fine-tuning basic values, it is probably wrong
