To elaborate a bit on the overall increase of amount of information in the universe, let's first look at extropy:
"Extropy is neither wave nor particle, nor pure energy. It is an immaterial force that is very much like information. Since extropy is defined as negative entropy — the reversal of disorder — it is, by definition, an increase in order. But what is order? Despite our intuitive sense, we lack a good operational definition of order, which seems to be tied up with complexity (see Ordained Becoming). For simple physical systems, the concepts of thermodynamics suffice, but for the real world of cucumbers, brains, books, and self-driving trucks, we don't have useful metrics for extropy. The best we can say is that extropy resembles, but is not equivalent to, information." --

Then next we can look at what information is. I didn't find any good definition now that I searched on the Web. Instead we can use the definition of digital information:
"A digital system is a data technology that uses discrete (discontinuous) values." --

We can model the entire universe using digital information. Can such model be complete? Maybe if reality is discrete. In any case the universe can be modeled using digital information to at least some degree of accuracy.
In order for extropy to increase, the amount of digital information to model the universe at any given point in time will also increase along the arrow of time. Even entropy can be included in that model, so we get: The total information in the universe at any given point in time is the amount of information required to model the total amount of entropy plus extropy in the universe.
Proposal: Information = Entropy + Extropy. And the total amount of entropy equals the total amount of extropy in the universe at any given point in time. Each moment in time contains an equal amount of information that is contained in all previous moments combined. This creates the arrow of time as an exponentially expanding amount of information which results in the process of evolution.
Any questions?
