Adam posted in a thread about theoretical physics. in his post he refuted general relativity and cited a paper that was recently self-published by one person on her own personal website and had no references to other works in the field.which important question did adam not answer sufficiently when evaluating the cited paper?

Ais a group of letters having a special meaning that appears at the beginning of a word.
