Chapter 4: Robustness and Physical Laws

In the previous chapter, we not only revealed that spacetime is a holographic projection, but also pointed out that it is essentially a set of Code. If the universe is code, it must face the oldest and deadliest threat in computer science: Errors.

Quantum fluctuations, environmental thermal noise, bit flips… At the Planck scale, the microscopic world is full of chaotic randomness. In principle, a system composed of such fragile components should crash (freeze) in the first second of operation.

However, our universe exhibits astonishing Robustness. Rocks are hard, planetary orbits are stable, atoms remain intact for billions of years.

Why? Because the universe is not just running; it is also self-checking.

This chapter will reveal that those cold physical laws we learn in textbooks—energy conservation, momentum conservation, charge conservation—actually have a hidden identity. They are Checksum Algorithms running in the universe’s underlying operating system to prevent data corruption.
