"When all you have is a hammer, everything starts to look like a nail"

Computational capacity of the universe

Merely by existing, all physical systems register information. And by
evolving dynamically in time, they transform and process that information.
The laws of physics determine the amount of information that a physical system
can register (number of bits) and the number of elementary logic operations
that a system can perform (number of ops). The universe is a physical system.
This paper quantifies the amount of information that the universe can register
and the number of elementary operations that it can have performed over its
history. The universe can have performed no more than 10120 ops on 1090 bits.

acho que é "10^120" e "10^90". se não, era pior que um sinclair zx81...

É isso mêmo. Por razões desconhecidas não passou quando fiz copy.
