What's wrong with having some reservations?
Ok, first off
my personal opinion
has little to no relevance in science.
You then follow your "personal opinion" with
Therefore, any attempt at answering a question that deals with the universe as a whole should be taken with at least a hint of skepticism
That's a mighty big conclusion to draw from your own personal opinion. It may well be true, but it hardly follows...
There was no error behind the catastrophe
The error was in
the classical physicists thought they had it all figured out
Believe me, none of us think like that (although a couple did back around 1980 with N=8 SUGRA, but they shall remain nameless)
Again, the cautious me says that we're bound to run into problems later on that may need to move onto a new model.
Of course there are problems. And of course there will be modifications and new models. But to direct the level of tentativity you did at the most basic elements of GR is naive. If I had been explaining the ways in which string theory can remove the singluarities of GR, or even how cold dark matter factors into the large scale structure of the universe, you would have a point. But we are talking about the most accurately tested theory known to man, a theory that is over 90 years old. It will require a bit more than anyone's "personal opinion" to budge.
Anyway, have you had a couple of drinks?
Not at all. I'm just very defensive about my life's passion. Just remember, what I described is not some new-fangled hyper-theoretical super-jargon - it is exactly as it would have been explained in 1915... except they wouldn't have had the luxury of ninety years of solid evidence to back them up!
