Have you ever wondered if our reality is just a computer program? It might sound like science fiction, but recent discoveries in physics have sparked intriguing discussions about the nature of our universe. A Nobel Prize-winning physicist has revealed that the universe is not “locally real.” But what does that mean?
The concept of “locally real” suggests that objects have definite properties, regardless of whether we observe them. For instance, the Moon orbits the Earth even when no one is watching. “Local” implies that objects are only influenced by their immediate surroundings, and any influence cannot exceed the speed of light. However, cutting-edge quantum physics experiments have challenged these ideas, suggesting they cannot both be true.
This revelation has led some to explore the simulation hypothesis, a theory popularized by philosopher Nick Bostrom. He suggests that if we ever develop supercomputers capable of creating entire universes with sentient beings, it might be more likely that we are living in a simulated universe rather than a real one. Bostrom argues that once such technology exists, there would be countless simulated universes compared to the few real ones, making it statistically probable that we are in a simulation.
Bostrom outlines three possibilities: First, almost all civilizations at our technological level go extinct before reaching technological maturity. Second, advanced civilizations lose interest in creating simulations of their ancestors. Third, we are almost certainly living in a computer simulation.
If the third possibility is true, it might seem like anything could happen. However, even in a simulation, the best way to predict future events is by observing patterns and making informed decisions, just as we do now.
Critics of the simulation hypothesis argue that there is no concrete evidence to support the idea that we live in a computer simulation. Some use the fine-tuning argument to suggest that the universe was created by a higher power, while others propose the multiverse hypothesis as a simpler explanation for the precise conditions that allow life to exist.
The fine-tuning problem questions why certain physical constants have values that enable complex chemistry and life. It seems unlikely that these values are coincidental. One theory is that there are many universes with different constants, and we exist in one where the conditions are just right for life, giving the illusion of fine-tuning.

Right now, we’re inside a computer program. Is it really so hard to believe? Elegant experiments with entangled light have unveiled a surprising discovery at the heart of reality. A Nobel Prize-winning physicist has shown that the universe is not locally real. But what does that mean exactly? “Locally real” means that objects have definite properties independent of observation. For example, the Moon is always in orbit around the Earth, even when no one is looking.
“Local” means objects can only be influenced by their surroundings, and that any influence cannot travel faster than light. However, investigations at the frontiers of quantum physics have found that these concepts cannot both be true. This discovery has prompted some to connect the dots with the simulation hypothesis. Philosopher Nick Bostrom argues that the notion of a simulated universe, similar to “The Matrix,” is plausible. Imagine one day we have powerful supercomputers that can create a universe in silico, complete with sentient beings unaware of their simulated existence.
Bostrom simplifies his argument: once we have the technology to create a simulated universe, there would likely be many more simulated universes than real ones. Real universes are hard to create, while simulated ones could be generated easily. Therefore, statistically, it is more likely that we are in a simulated universe.
The simulation hypothesis proposes that all of our existence is a simulated reality. Bostrom explains that one of three possibilities must be correct. The first possibility is that almost all civilizations at our technological stage go extinct before reaching technological maturity. The second possibility is that civilizations that do reach maturity lose interest in creating ancestor simulations. The third possibility is that we are almost certainly living in a computer simulation.
If we assume the third possibility is true, many people’s first reaction might be to think anything could happen. However, upon reflection, we realize that even if we are in a simulation, the best way to predict what will happen next is still through the methods we would use anyway. We observe patterns in our reality, extrapolate them, and act accordingly.
Critics of the simulation hypothesis point out that proponents have not provided evidence that we live inside a computer simulation. The fine-tuning argument has been used by some to suggest that the universe was created by a higher power, but proponents of the simulation hypothesis also use it. The multiverse hypothesis may offer a simpler explanation for the fine-tuning of constants that allow life to exist.
The fine-tuning problem raises questions about why certain physical constants have values that enable complex chemistry and life. While it could be coincidence, it seems unlikely that these values would just happen to be right by chance. Some suggest that there may be a large ensemble of universes with varying constants, where most universes lack observers. Observers only exist in those universes where the values are conducive to life, leading to the perception of fine-tuning.

This version maintains the essence of the discussion while ensuring clarity and appropriateness.
Simulation – A method for implementing a model over time to study the behavior and performance of an actual or theoretical system. – In physics, computer simulations are often used to predict the behavior of complex systems, such as weather patterns or particle interactions.
Physics – The natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. – Physics provides fundamental insights into the workings of the universe, from the smallest subatomic particles to the largest galaxies.
Universe – The totality of known or supposed objects and phenomena throughout space; the cosmos; macrocosm. – Philosophers and physicists alike ponder the origins and fate of the universe, seeking to understand its vast complexities.
Reality – The state of things as they actually exist, as opposed to an idealistic or notional idea of them. – Quantum mechanics challenges our traditional notions of reality, suggesting that particles can exist in multiple states simultaneously.
Technology – The application of scientific knowledge for practical purposes, especially in industry. – Advances in technology have allowed physicists to explore the universe in unprecedented detail, from the depths of the ocean to the far reaches of space.
Consciousness – The state of being aware of and able to think about one’s own existence, sensations, thoughts, and surroundings. – The nature of consciousness remains one of the most profound questions in both philosophy and physics, as scientists explore the brain’s role in shaping our perception of reality.
Possibilities – Things that may happen or be the case; potential outcomes or scenarios. – The multiverse theory in physics suggests that there are infinite possibilities, with each universe having its own distinct laws and constants.
Constants – Quantities that are universally invariant and fundamental to the laws of physics. – The speed of light in a vacuum is one of the most well-known constants in physics, serving as a cornerstone for the theory of relativity.
Philosophy – The study of the fundamental nature of knowledge, reality, and existence, especially when considered as an academic discipline. – Philosophy often intersects with physics, as both fields seek to answer profound questions about the nature of existence and the universe.
Existence – The fact or state of living or having objective reality. – The question of existence is central to both philosophy and physics, as scholars debate the nature of being and the origins of the universe.
