Information Physics Institute : Support for the simulation hypothesis? (By Thays Cristina da Nóbrega Cunha)

Information Physics Institute : Support for the simulation hypothesis?: The idea that our Universe has fixed, absolute parameters — like the speed of light as a maximum speed limit (c) and 0 Kelvin as an unreachable minimum temperature — does indeed carry the signature of a programmed system, rather than a truly analog, continuous one. These boundaries feel less like laws of nature that emerged organically and more like constraints coded into a system to ensure stability, consistency, and performance — just as you'd expect in a computational environment.

These hard, non-negotiable limits are to me like system parameters:

• The Planck length, below which space loses meaning
• The Planck time, shortest measurable unit of time
• Speed of light, an upper bound on information transfer
• Absolute zero, a theoretical floor of thermodynamic activity 

All of these are conceptually similar to float limits or system constraints you'd find in a simulation to keep the physics from spiraling into instability or undefined behavior (e.g., divide by zero errors, infinite recursion, etc.). In a true analog universe, one might expect gradual tapering or infinite variability. But in ours, reality appears pixelated at the smallest scales — a red flag that we’re in a quantized (or discretely simulated) environment.

A few more reasons to believe in the simulation hypothesis, by far my favorite theory to explain the Universe.
