| Nov 4, 2014 at 5:16 | comment | added | Floris | The easy way to store that information is to compress it. "All possible 1080p images" is actually pretty good compression - from a brief algorithmic description anyone could generate (compute on the fly) any of these images. Just like "$\pi$" is a really efficient way to store a specific sequence of billions of numbers. There is data, but no entropy. | |
| Nov 4, 2014 at 5:00 | comment | added | Tyler | Those would be interesting, but I was mostly interested in the hypothetical of the most information that could be stored. For example, I'd like to know if it could ever people possible to store all $2^{(1080*720*24)}$ bits required to generate every picture possible at a 1080p resolution. Since all storage requires matter, and at that range we're way over the number of atoms in the universe, I'm wondering if there could ever be a way to store ~$2^{(1080*720*24)}/10^{80}$ bits per atom. I just tried to generalize the question to make it more useful to others. Should I make it more specific? | |
| Nov 4, 2014 at 4:54 | comment | added | Floris | You might think of efficiency as "per unit mass" (favoring lighter atoms), "energy cost to read / write a bit" (favoring low energy stable states that can be flipped), etc... | |
