The Fermi Paradox—the contradiction between the high probability of alien life and its lack of evidence—is resolved by the simulation hypothesis. A resource-constrained simulation would only render what an observer needs to see, leaving the rest of the cosmos computationally dormant to save processing power.

A particle's quantum state collapses not due to a conscious observer, but when any physical interaction captures information about its path. This suggests the universe is a system responding to information processing, where computation is more fundamental than matter.

In algorithm design, randomness isn't free. High-quality random bits (from quantum sources) are expensive, while cheaper sources (thermal noise) have lower quality. This reframes randomness as a resource to be managed and minimized, just like time or space complexity.

Physicist Michio Kaku refutes simulation theory by highlighting a core principle of quantum mechanics: the universe is based on inherent probabilities, not a predetermined script. This fundamental randomness is at odds with the concept of a controlled simulation.

The universe is not "locally real," meaning objects exist as probabilities until observed. This mirrors video game engines that only render objects in a player's view to conserve computational resources, suggesting our reality is similarly efficient.

A 2008 experiment showed researchers could predict a person's choice up to ten seconds before the person consciously made it. This suggests our conscious mind merely rationalizes decisions already made by unconscious processes, indicating free will is an illusion.

A coin toss is random to a human but predictable to a supercomputer with high-speed cameras. This shows randomness is not an inherent property of an event, but a reflection of an observer's inability to compute the outcome. The less powerful the observer, the more random an event appears.

The 'three-body problem' in physics shows that a system can follow deterministic laws perfectly yet be impossible to predict without simulating every step. This demonstrates that unpredictability and freedom are not the same, explaining why life feels 'free' even if it is predetermined.

The Nobel Prize-winning discovery that the universe is not locally real suggests it operates like a video game engine, rendering reality only when an interaction or measurement occurs. This principle of computational efficiency, along with the universe having a minimum pixel size (Planck scale) and tick speed, strongly supports the simulation metaphor for reality.
