An old post that I’m bumping back up to the top because of the interest it has generated…
In finishing up my new science fiction novel I went through a lot of research on Laplace’s Demon. In the process, I stumbled onto the computational limit of the universe. Based on the minimum amount of time you need to move data across the Planck length, at the speed of light, there’s a limit to the computational power of the universe that’s about 10-to-the-power-of-120 bits (actually 10^120 operations on 10^90 bits of data). Anything needing more data can’t be computed in the fifteen billion years or so that the universe has existed so far. Calculating the location of every atom in the universe would require more than 10^120. Ergo, omniscience is impossible even for a computing organism the size and age of the universe.

One is the “manager” mode that recently got an “out of memory” error on my 4gig laptop–I was running with 50 Adobe documents open, 50 Excel documents, most with multiple sheets, 140 tabs on Firefox, 19 Word documents, one very long Power Point slide show, and a bunch of other stuff open, all with my son running in and out showing me the good guy beating the bad guy, informing me that “Dad, these superheroes saved the day!” and asking the names of odd colours, like fuchsia. I told him to ask his mother, she’s a painter, she paints with colours. He said, “And you’re a writer? So you know what’s right?”
