There is a question that resurfaces from time to time, perhaps at night, when the mind is tired and reality seems a bit out of focus: what if this is all a simulation? Not a dream, not a hallucination, but a giant computer program. An idea that sounds like something out of The Matrix, and has been floating around for years among philosophy, physics and pub discussions.
Now, however, something interesting is happening. A group of researchers led by theoretical physicist Mir Faizal has decided to take this question seriously, without red or blue pills, but with formulas, theorems and a lot of patience. And the conclusion they come to is quite stark: no, our universe is not a simulation.
The idea that everything is fake comes from the movies
Simulation theory was not born to make us doubt that spoon on the table. In 2003, philosopher Nick Bostrom speculated that a technologically advanced civilization might have the means to simulate entire universes, complete with consciousness. It was not science fiction, but logical reasoning: if technology continues to grow, why rule out this possibility?
From there, the idea began to circulate. Some saw it as a philosophical provocation, others as an alternative explanation for everything we don't understand. And in between are those who occasionally look at the world and think: could it be that that's all there is?
Physics makes its appearance and dismantles the idea of programmed reality
The work of Faizal and his team actually begins at a very concrete point: the deep structure of reality. Indeed, according to some quantum gravity theories, space and time are not fundamental building blocks, but arise from something more abstract, a kind of 'pure' information. A concept more reminiscent of Plato's thinking than that of a computer engineer.
And this is exactly where simulation begins to fail. Because, if the universe were really a program, it should be completely describable by computation. But it isn't. The researchers show that there are aspects of reality that elude any algorithm, even using Gödel's famous incompleteness theorem. Even the most powerful supercomputer cannot contain everything that makes our world so real.
Faizal puts it bluntly: "a truly complete physical theory cannot just be computational. It needs something beyond code, beyond instructions, beyond the idea of a program."
This answer affects us more than we think
There is a reason why the simulation hypothesis fascinates us so much. It's not just technology, it's an emotional issue. Thinking everything is 'fake' eases the weight of things, makes pain more distant, choices less final. But at the same time, it deprives us of something: the responsibility to really be there.
This research not only shows that we do not live in a cosmic video game, but also grounds us to an imperfect, complicated, sometimes frustrating, but authentic earth. There is no next level to unlock, no reset button. There is this reality, with all its unprogrammable complexity.
And perhaps that is the most reassuring point.
