Okay, let's stick with cosmic forces, shall we?
This one is all about "Information Theory."
*Suppose that it is possible to describe the universe in terms of it all being "particles of information." In fact, suppose that everything can be reduced to the familiar ones and zeros (1, 0) "bits" - or
quanta which can be 0, 1, or
both - at their most basic level. Then the current state of every "bit" in the universe is its "memory," and since the universe is finite, that memory must be finite as well.
Interestingly, we can then consider the universe itself to be a type of "computing device," modifying information as time passes.
Well guess what? Some smart dudes sat down and worked out an estimation for just how many bits that is! (Hint: This involves the Plank constant, speed of light, and the amount of time since the big bang....)
The result?: Our universe has performed about 10
120 "ops" in its entire history!
Now for The Question: Considering "every degree of freedom of every particle in the universe" how many "bits" could our universe now hold? (Hint: It has to be a number SMALLER than the number of "ops....") An answer within +/- two powers of ten is acceptable.* So if this all made your head implode, JUST GUESS!
