How Stephen Hawking might approach Computer Science

The question of “computer science” is, in essence, a question about computation itself, and computation is a fundamental aspect of how the universe operates. The universe, after all, can be viewed as a colossal information processor. Its laws, from the grand sweep of gravity shaping galaxies to the delicate dance of subatomic particles governed by quantum rules, are algorithms.

We grapple with these algorithms through mathematics. General relativity, for instance, describes the geometry of spacetime as a solution to Einstein's field equations. These equations are a form of computation, dictating how matter and energy warp the fabric of existence. Quantum mechanics, with its probabilistic wave functions and superposition, presents a different, albeit complementary, computational model.

The "computer" in computer science is merely a tool, an abstraction that allows us to explore these underlying computational principles. Think of a black hole. It possesses an event horizon, a boundary beyond which information is lost to our classical understanding. Yet, through quantum mechanics, we discovered Hawking radiation – a leakage of energy, a ‘computation’ occurring at the edge of this singularity, suggesting that information might not be entirely destroyed. This interaction between gravity and quantum mechanics, the very frontier of our understanding, is where true computational breakthroughs lie.

The ultimate goal, of course, is a single, unified theory that describes all these computational processes. A true ‘Theory of Everything’ would be the ultimate algorithm, revealing the universe’s deepest computational secrets. Whether we build machines that mimic these processes, or whether our brains themselves are such machines, the underlying question remains: how does the…
