Life cannot go on forever. It has at most 10^120 operations left, and then all life in the visible universe will go extinct. The information stored and preserved by those living creatures will then be irreversibly dissipated. Though the information is never truly destroyed, it will be scattered, useless, throughout the dark, lifeless cosmos.
This is the ultimate irony of the laws of information. Physicists are using information to figure out the most profound questions of the universe. But at the same time, those tools of information theory have revealed our ultimate fate. We will die, as will all the answers we have to these questions--all the information our civilization has gathered. Life must end, and with it will end all consciousness, all ability to understand the universe.
