I hope "The End" is not the end of this discussion... Agreed that new revelations are made when you question the obvious... Galileo questioned Aristotle...But he was able to substantiate what he told... Its as simple as the difference between throwing a statement in air and making a statement backed with proof...This is what I meant with the term prediction and this also makes the diffrence between a prediction and making a wild guess... Whenever we find a person with a Ph.D we tend to respect him, just because of that he had done something good about something... Of course not all Ph.Ds can be great but its a standard that everybody accepts to recognise one's expertise. The point I made is straight dear kishore..I dont mind you questioning the obvious...But you can only when you substantiate yours BTW why no posts from the rest in the buddy list?
