For centuries, philosophers like Plato have pondered the possibility that what we perceive might not be the true reality. With the rise of computers, this idea has been revitalized, especially with films like Inception, Dark City, and the Matrix trilogy. Could our world really be a simulation created by some advanced system?
10. Simulations by Our Ancestors
Modern computers are capable of processing massive amounts of data, with many of the most complex and impactful tasks revolving around simulations. These simulations take into account a variety of variables and often use artificial intelligence to analyze possible outcomes. Some are simply games, while others model real-world scenarios, such as the spread of diseases. There are even 'history simulators,' which can range from games like Sid Meyer’s Civilization to more sophisticated models simulating the development of societies over time.
Simulations operate based on the current speed of computers, but as processing power continues to double, the systems of the future will be exponentially more powerful. In 50 years, computers could be millions of times more capable than today's models. These advanced systems would pave the way for much more sophisticated simulations, including historical ones. If computers reach a level of power like that, they could create simulations so immersive and lifelike that the sentient beings within them would have no awareness of being part of a program.
Think that sounds far-fetched? Harvard’s Odyssey supercomputer can simulate 14 billion years of history in just a few months.
9. If It’s Possible, It Will Happen
So, while creating a universe within a computer might be feasible, the ethical implications are significant. Humans are deeply complex, with emotions and relationships that form the fabric of our existence. Would it be morally right to create an entirely fabricated world filled with beings like us? Who would bear the responsibility for the actions of those within the simulation, and would it be too much for us to handle?
Perhaps. But that’s beside the point. For some, the allure of creating a simulation would simply be irresistible. Even if history simulators were banned, it would only take one person to defy the law and create our reality. Just one individual could view it no differently than a game of The Sims.
There might also be legitimate reasons for developing such simulations, beyond mere amusement. Humanity could be on the brink of extinction, prompting scientists to create our world as a massive diagnostic tool. The simulation would serve as a way to identify what went wrong in the real world and help find solutions to save themselves.
8. Obvious Flaws
If a simulation is sophisticated enough, the beings within it wouldn’t recognize it as a simulation at all. If you were to place a brain in a vat and stimulate it, the brain would not know it was in a vat. It would perceive itself as a real, living, breathing individual.
Even the most sophisticated simulations can have glitches, right? Wouldn’t we notice some imperfections or a ‘glitch in the Matrix’?
Perhaps we already experience these glitches in our daily lives. The Matrix suggested that déjà vu—when something feels oddly familiar—could be a sign that the simulation is skipping, like a scratched CD. Supernatural occurrences, like ghosts or miracles, might also be glitches. According to simulation theory, these phenomena are real, but they happen because of bugs in the simulation’s code.
The Internet is filled with anecdotal evidence of such glitches. Stay alert, and perhaps you’ll spot one yourself.
7. Math Governs Reality
Everything in the universe can be measured in some way. Even life itself, despite medicine’s history as an ‘imprecise science.’ The Human Genome Project, which mapped the chemical base pairs of human DNA, was solved using computers. All the mysteries of the universe are unraveled through mathematics. In fact, math offers a clearer explanation of the universe than words ever could.
If everything is mathematical, it could all be reduced to binary code. If computers and their data capabilities evolve sufficiently, could a functional human being be created by encoding the genome sequence into a computer? And if one person can be created, could an entire world of them be built?
Some scientists believe that someone may have already accomplished this and created our world. To find out if we are living in a simulation, researchers are conducting serious investigations—by examining the math behind our universe.
6. The Anthropic Principle
It’s remarkable that humans exist at all. For life to emerge on Earth, everything had to align perfectly. We’re at the ideal distance from the Sun, the atmosphere has the right composition, and gravity is perfectly balanced. While other planets might share these conditions, life becomes even more extraordinary when we broaden our view beyond Earth. If a cosmic force like dark energy were even slightly stronger, life probably wouldn’t exist, here or anywhere in the universe.
The anthropic principle asks the question, ‘Why? Why did these conditions align so perfectly for us?’
One possible explanation is that these conditions were intentionally created to allow life. Every favorable factor was predetermined in some grand experimental setup. The variables were simply plugged into the universe, and the simulation began. This allowed existence, and our planet, to evolve as it has.
A consequence of this idea is that those responsible for the simulation may not be humans at all. It could be another form of intelligence running it, deliberately concealing their presence. Perhaps alien life forms have figured out how to manipulate the simulation and keep themselves hidden from us.
5. Parallel Universes
The theory of parallel universes, or the multiverse, suggests that an infinite number of realities exist, each containing endless possibilities. Think of it like the floors of an apartment building. Universes are part of the multiverse in the same way that floors are part of the building—they follow a similar structure, yet each one is unique and contains different things. Jorge Luis Borges compared the multiverse to a library filled with an infinite number of books, some of which are only slightly different by a letter, while others tell entirely different stories.
The theory comes with all sorts of mind-boggling implications about the meaning of life. But if multiple universes exist, why do they exist? What’s the reason behind their vast number?
If we are living in a simulation, these multiple universes are simply multiple simulations running simultaneously. Each simulation has its own specific set of variables, and this is not by chance. The creator of the simulation inputted various variables to experiment with different scenarios and observe diverse outcomes.
4. Fermi’s Paradox
Our planet is just one of many that could potentially support life, and our sun is relatively young compared to others in the cosmos. Given this, you might expect to find evidence of life elsewhere—from planets where life evolves alongside ours or from ones where life began long before ours.
Moreover, humans have already ventured into space, so shouldn’t other civilizations have attempted space travel as well? With billions of galaxies out there, some far older than our own, isn’t it likely that at least one of them has mastered space travel? Given Earth’s life-supporting conditions, you might even expect Earth to have been colonized by an advanced civilization by now.
Yet, no signs of intelligent life beyond Earth have been discovered. The Fermi Paradox can be summed up simply as—“Where is everybody?”
This ties back to simulation theory in several ways. If life should exist elsewhere, yet only exists on Earth, it could point to the possibility that we are in a simulation. Those running the simulation might have chosen not to simulate life anywhere else, either for simplicity or to observe how humans behave in isolation.
The multiverse theory suggests that life exists on other planets in most universe simulations. Ours, however, is the one simulation where humanity is the only intelligent life in the universe. Returning to the anthropic principle, it may be that this universe was designed specifically for us.
Another theory, known as the planetarium hypothesis, provides a different explanation. According to this idea, the simulation causes various inhabited planets to believe they are alone in the universe. Perhaps the purpose of this is to observe the effects of inflated ego on the progression of civilization.
3. Fake People Make For Easy Simulations
Even if computers advance significantly, simulating the entire universe might still be a daunting challenge. Each of the seven billion people on Earth is complex enough to stretch any imaginable computer’s capacity. And considering we’re only a small part of an enormous universe containing billions of other galaxies, accounting for all these variables would be overwhelmingly difficult, if not impossible.
A simulated world doesn't need to be as intricate as it might first appear. A convincing simulation could be composed of a few well-detailed main characters, with many secondary figures who barely exist beyond the surface. Consider games like the Grand Theft Auto series. They feature hundreds of people, but you only interact with a select few. Life could function similarly—you interact with your close family and friends, but everyone else you encounter might not be 'real.' They're just passing figures with few thoughts, no emotions, and are essentially window dressing.
Let’s stick with the video game metaphor for a moment longer. These games are set in vast “worlds,” yet only the part you're in right now has any real activity. The rest is stored away and activated only when necessary, saving on processing power. The same could apply to our reality. Far-off locations—like distant galaxies—don't need to be continuously simulated. They only need to display convincing visuals when you attempt to look at them.
Forget about the people you pass on the street or the far-off stars. You don’t even have solid evidence of your own existence as the person you believe yourself to be. We assume the past happened because of our memories and things like photos and books. But what if all of that is simply freshly generated code? What if your life was reset the last time you blinked?
The troubling part is that there’s no way to definitively prove or disprove this.
2. Outside The Universe
What lies beyond our universe? In the context of simulation theory, one might imagine a supercomputer surrounded by advanced entities—but there's an even wilder possibility to consider.
The beings running our simulation might be as artificial as we are. There could be multiple layers of simulations. As Oxford philosopher Nick Bostrom posits, “The post-humans running our simulation are themselves simulated beings; and their creators, in turn, may also be simulated beings. This opens the door to potentially countless layers of reality, with the number growing over time.”
It’s like playing The Sims and continuing the game until your characters create their own Sims game. Those Sims, in turn, develop and play their own simulation, while you remain secretly part of an even grander simulation.
This still leaves the question: What exists outside the creator’s “real” universe? It’s a concept so distant from our reality that it may be impossible to fully fathom. However, if simulation theory can at least offer an explanation for the finite nature of our universe and hint at what lies just beyond it . . . well, that’s a solid starting point in understanding the essence of existence.
1. God Is A Programmer
For centuries, humans have envisioned God as the designer of the universe. While some imagine a deity as a bearded figure in the clouds, simulation theory suggests that such a god (or any other) could be a programmer, glasses perched on their nose, hunched over a keyboard.
As we've discussed, a programmer can create entire worlds from basic binary code. The real question is why the programmer would instill in us the desire to worship our creator, which is a fundamental aspect of many religions.
This could be either intentional or accidental. Maybe the programmer wanted us to recognize their presence and embedded within us a sense of being created. Alternatively, the programmer might not have planned this, but we've developed an intuitive sense of the creator’s existence anyway.
The concept of a god as a programmer aligns with the notion of intelligent design in two ways. First, it suggests that code initiated life, allowing everything to evolve within the simulation to the present moment. Second, it might even validate Creationism as described in the Bible—just as the Bible states that God created the world and life in seven days, he may have used a computer rather than divine powers.
