How Much Information?

by on February 17, 2011

Here’s an attempt to figure out how much information the world contains.

Looking at both digital memory and analog devices, the researchers calculate that humankind is able to store at least 295 exabytes of information. (Yes, that’s a number with 20 zeroes in it.)Put another way, if a single star is a bit of information, that’s a galaxy of information for every person in the world. That’s 315 times the number of grains of sand in the world. But it’s still less than one percent of the information that is stored in all the DNA molecules of a human being.

You can find the rest of the numbers here: How Much Information is there In the World?
