How many times have I heard that from the terminally lazy on this
newsgroup. 

As though anything worthwhile has no depth or complexity.

EXACTLY the point of fundamental research — exploration and knowledge with
no emphasis on practicality. Engineers have a hard time understanding the
value of this.

Feel free to question. There are oodles of books on the subject. 

Just don’t expect, like so many hacks, that a clear explication of the
theory and the experimental evidence will be forthcoming in a few simple
paragraphs on Usenet. That can’t be done for Newtonian mechanics or quantum
mechanics or plate tectonics or evolution either.
