If shit happens I won't be able to stop it. So I really don't care I am going to live my life normally and laugh at all the idiots who plan to spend all their money to have fun 'before the end' racking up tons of debt only to find out; now they need to pay it back because the world didn't end like it was supposed to.
As far as the blackhole never heard that one before, and I am sure I would have; though I did hear the Mayan Calendar and other calendars, as well as your 'predicting things that happened today that are impossible'. Well, thats a matter of words.
"Something groundbreaking will happen tomorrow."
I am probably pretty accurate with that prediction. It doesn't say WHAT will be groundbreaking WHO will do it or even what consists of 'groundbreaking' Meaning I could write some amazing algorithm that saves 2 CPU cycles while searching through a database, and on some levels that is considered groundbreaking...
My point is the statements people seem to think are predictions are simply to vague and not taken in their context IMO. I will not say that there couldn't be truth in anything, I like the idea that people could accurately predict things, but until they start actually making predictions that I feel are not vague I will not go jumping on board.
