In the abstract it’s far from obvious that there should be a simple, ultimate theory of our universe. Indeed, the history of physics so far might make us doubtful—because it seems as if whenever we learn more, things just get more complicated, at least in terms of the mathematical structures they involve. But—as noted, for example, by early theologians—one very obvious feature of our universe is that there is order in it. The particles in the universe don’t just all do their own thing; they follow a definite set of common laws.

But just how simple might the ultimate theory for the universe be? Let’s say we could represent it as a program, say in the Wolfram Language. How long would the program be? Would it be as long as the human genome, or as the code for an operating system? Or would it be much, much smaller?

    This piece has some interesting ideas, although the logic is flawed IMO.

    About the same time as Einstein published his theory Russel and Wittgenstein saw that a theory is just a possible explanation for a phenomenon and cannot provide logical basis for it.

    Reading through it, makes it apparent for me that while he thinks that he is searching for the ultimate theory he is ultimately just chasing his own tail.
