Subject: Perfect play

Hello all!!
I'm a newbie when it comes to computer chess so please forgive me if my
questions have already been answered.
Has anyone ever calculated the total number of possible moves in a game
of chess? If so, it would logically follow that the nps would translate
into the percentage of possible moves needed to play a perfect game of
chess. i.e. at what point in nps would the program be able to spot a
mate or draw after say 1.e4? A trillion nps? An octillion nps? I'm
thinking that even these guesses are quite low as to what would actually
be required, even if the above program were allowed to think for 3
months on move 1.
Since the laws of physics have given us an unsurpassable upper limit
when it comes to processor speed (you can't go faster than light
speed)will we ever solve the game? Even with multiple processors?
If such a feat is ever accomplished will the mythical program doing it
have any knowledge based evaluation functions or will the shear speed of
such a program negate any need for knowledge based evaluation?
Thank you in advance.
