Has there ever been a serious debate regarding the "holographic universe" idea?

Question

I mean a real debate, where someone for and someone against the idea got to present their respective cases, and rebut the other's case? Has there ever been serious discussion on this, or has "mainstream" science just rejected it out of hand?

Answer 1

If you're referring to the holographic principle (see reference), yes it is seriously considered. Debated isn't the best term, since science should (and usually does) consider a conjecture by trying to determine whether or not it is true, not by trying to win an argument.
