As humans, our perception of the universe is inherently limited. Our senses and brains can only process a small fraction of the world around us. To truly understand the nature of reality, we rely on concepts and technological tools. While technological advancements have expanded our knowledge of the universe, they have also introduced unsettling possibilities. One such possibility is the simulation hypothesis, which suggests that it might be feasible to simulate entire universes. But if this is possible, how can we be sure that it hasn’t already happened? Could we be creations rather than creators? Is it conceivable that our reality is not real, and we are unaware of it?
If our current understanding of physics holds true, simulating the entire universe with its countless elements seems impossible. However, a complete simulation may not be necessary. We only need enough of a universe to convince the inhabitants of the simulation that they are real. The vastness of the universe could be a mere projection, and we would have no way of knowing. Similarly, microscopic entities like cells or bacteria might not exist until observed under a microscope. Even the chair you’re sitting on might not be composed of quadrillions of atoms; it could be hollow until you decide to break it open. The minimum requirement for a simulation is the consciousness of its virtual inhabitants. As long as they believe the simulation is real, the illusion is complete.
So, are we living in a simulation? While it’s a possibility, several conditions must be met for this to be true. Here are five assumptions based on a modified version of Nick Bostrom’s original simulation argument:
To simulate consciousness, we must first understand what it is, which remains a mystery. For argument’s sake, let’s assume consciousness can be generated by simulating a brain. The human brain is incredibly complex, performing approximately 100 million billion operations per second. To simulate one second of human consciousness, we might need 1020 operations. Simulating all of human history, with 200 billion humans living an average of 50 years, would require a computer capable of performing more operations than there are stars in the observable universe. Such a computer seems impossible, but perhaps it isn’t.
If technological progress continues at its current pace, galaxy-spanning civilizations with unlimited computing power might emerge. These advanced beings could possess technology indistinguishable from that of gods. Concepts like the Matrioshka Brain, a theoretical megastructure orbiting a star, could potentially handle the immense computational demands of simulating numerous human civilizations simultaneously. Future quantum computers might reduce the size of such structures, making them feasible on a smaller scale.
If all advanced civilizations destroy themselves, the simulation hypothesis becomes moot. The absence of observable alien civilizations might be due to “Great Filters,” barriers like nuclear war, asteroids, or climate change that life must overcome. If life is inherently self-destructive, simulations may not exist.
We cannot presume to understand the motivations of posthuman civilizations. To them, running simulations might be as trivial as an ant trying to comprehend an amusement park. However, if they do wish to run simulations and the previous assumptions hold true, the likelihood of us living in a simulation increases.
If advanced civilizations run simulations, they would likely create millions or billions of them. With practically unlimited computing power, the majority of conscious beings might be simulated. This means that for every flesh-and-blood human, there could be billions of simulated ones. Without a way to determine if we are simulated, the odds of being one of the countless simulated beings are high.
While the simulation hypothesis is based on assumptions we cannot currently test, it remains a fascinating thought experiment. Many scientists disagree with its plausibility. Regardless of whether we are simulated, our existence remains unchanged. We continue to live on a small planet in the vastness of space, or perhaps within a computer simulation. Our lives are no more or less bizarre. All we can do is strive to live well and enjoy our time, hoping that if we are simulations, no one accidentally unplugs the power source.

Simulation – A representation or imitation of a process or system, often used to study its behavior under different conditions. – In physics, scientists use computer simulations to model the behavior of particles at the quantum level.
Consciousness – The state of being aware of and able to think and perceive one’s surroundings and existence. – Philosophers often debate whether consciousness can be fully explained by physical processes in the brain.
Reality – The state of things as they actually exist, as opposed to an idealistic or notional idea of them. – In philosophy, the nature of reality is a central question, with discussions on whether it is objective or subjective.
Technology – The application of scientific knowledge for practical purposes, especially in industry. – Advances in technology have allowed physicists to explore the universe in ways that were previously unimaginable.
Universe – The totality of known or supposed objects and phenomena throughout space; the cosmos. – The study of the universe’s origins and structure is a fundamental aspect of cosmology in physics.
Existence – The fact or state of living or having objective reality. – Philosophers have long pondered the question of human existence and what it means to be.
Civilizations – Complex societies characterized by urban development, social stratification, and symbolic communication forms. – The development of ancient civilizations often relied on advancements in technology and understanding of the natural world.
Assumptions – Things that are accepted as true or as certain to happen, without proof. – In physics, assumptions are often made to simplify complex problems and make them more manageable.
