I often hear about how solving some problem would require a computer "the size of the known universe", or something like that. Is there a "unit" of computing power?(adsbygoogle = window.adsbygoogle || []).push({});

How many units of this power would say a 1cm^3 cube of hot gas have? In other words assuming you wanted to simulate the actual atoms bouncing around, how many units would it take to simulate this perfectly?
