In his book, The Sentient Machine, Amir Husain writes:

Today I find myself drawn to the important observation that the universe around us is clearly a consequence of computation. A seed, for example, encodes the information necessary to produce a tree. With DNA as the software and cells and proteins as the hardware, the biological process is a computational one. We find these types of algorithmic outcomes everywhere we look in the universe.

Patterns like the Fibonacci sequence, for example, unlock designs across our cosmos. Everything from flower petals to the curving shells of a mollusk, to spiral galaxies, to hurricanes, adheres to this mathematical formula. Is this by chance?

There seems to be a mathematical seed at the heart of the cosmos that through the power of computation, has been magnified into the universe as we know it, just as a tree is a magnified seed.

At some point in my early adolescence, I tried to imagine a future where all of science fused together. All the deductions completed and all the building blocks of science synthesized into a great pyramid of knowledge. At the very top of this pyramid however, I realized that I was still missing a block that tied it all together. That block is the ultimate question, “What is this all for?’”

He then concludes with a chilling realization, that even with all of our advancements, “we still don’t know the purpose for our existence."

Possible Preaching Angle:

As a Christian, we would argue, that just as a computer program begins in the mind of a computer scientist, the mathematical patterns that govern our universe are testimony to a Programmer. And just as a computer program must run on hardware, that is itself manufactured by an intelligent being, the universe itself bears witness to a supernatural Creator.
