Simulating a system, like a fruit fly's brain, doesn't replicate its reality, only our observations of it. The universe itself generates physical structures that are too complex to be simulated within its own computational limits, showing the fallacy of equating simulation with reality.

Elon Musk's take on the simulation hypothesis includes a 'Darwinian' twist. Just as humans discard boring simulations, any creators of our reality would do the same. Therefore, the simulations most likely to continue are the most interesting ones, making 'interesting' outcomes the most probable.

Philosopher Nick Bostrom argued statistically that we are likely in a simulation. Recent physics proving the universe is not locally real and behaves computationally provides empirical evidence that aligns with the structural requirements of Bostrom's hypothetical simulation.

Recent physics experiments suggest the universe isn't "locally real," behaving like a simulation that only renders what is being observed. A tree falling on Mars may not actually fall until it's measured, similar to how an unseen area in a video game doesn't render.

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.

Our current computation, based on Turing machines, is limited to "computable functions." However, mathematics shows this set is a smaller, countable infinity compared to the vast, larger infinity of non-computable functions. This implies our current simulations barely scratch the surface of what is mathematically possible.

If any civilization can create a convincing simulation, and those simulations can create their own simulations, the number of simulated realities would vastly outnumber the single "base reality." This makes it statistically probable that we are living inside one of the countless nested simulations rather than the original one.

The double-slit experiment in physics shows that the mere act of observing particles changes their behavior. This indicates that reality is not fixed but is influenced by consciousness, leading Sinclair to believe there's a >50% chance we live in a simulation.

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.
