The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing our reality are simply algorithms. The experiences we have are generated by the computational processes of an immensely advanced system.

While inherently speculative, the simulated theory has gained attention from scientists and philosophers due to its intriguing implications. The idea has made its mark in popular culture, across movies, TV shows and books—including the 1999 film "The Matrix."

The earliest records of the concept that reality is an illusion are from ancient Greece. There, the question "What is the nature of our reality?" posed by Plato (427 BC) and others, gave birth to idealism. Idealist ancient thinkers such as Plato considered mind and spirit as the abiding reality. Matter, they argued, was just a manifestation or illusion.

Fast forward to , and idealism has morphed into a new philosophy. This is the idea that both the material world and consciousness are part of a simulated reality. This is simply a modern extension of idealism, driven by recent technological advancements in computing and digital technologies. In both cases, the true nature of reality transcends the physical.

Within the , the concept of a simulated universe has sparked both fascination and skepticism. Some scientists suggest that if our reality is a simulation, there may be glitches or patterns within the fabric of the universe that betray its simulated nature.

However, the search for such anomalies remains a challenge. Our understanding of the laws of physics is still evolving. Ultimately, we lack a definitive framework to distinguish between simulated and non-simulated reality.

If our physical reality is a simulated construct, rather than an objective world that exists independently of the observer, then how could we scientifically prove this? In a 2022 study, I proposed a possible experiment, but it remains untested today.

However, there is hope. Information theory is the mathematical study of the quantification, storage and communication of information. Originally developed by mathematician Claude Shannon, it has become increasingly popular in physics and is used a growing range of research areas.

In my recent research, published in AIP Advances, I used to propose a new law of physics, which I call the second law of infodynamics. And importantly, it appears to support the simulated universe theory.
