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 universe 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 modern times, 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 scientific community, 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.
I mean, is there really potential for infinite simulated ones? It doesn't make sense to be able to simulate a more powerful computer than the one running the simulation, else any computer would be able to have effectively infinite processing power with recursive simulations, so each "layer" of the simulation is logically going to have less processing power available for it than the layer above, probably a lot less. After a certain point, shouldn't it reach a state where reality as we perceive it is too computationally intense to simulate?
The latest season of Futurama actually illustrated this, that due to time being relative you can just slow down the simulation to reduce the requirement to run at a 1:1 performance ratio with our current environment.
It also describes that someone from flatland wouldn't be able to tell that they're missing out on a dimension, or quality, because it's their only frame of reference.
Definitely not scientific in approach, but it is thought provoking around the possibility of a simulated existence.
It's not even hypothetical, as simulations go; Eve Online does this in-game with a Time Dilation system that dynamically slows down the tick rate in systems that are under heavy traffic, to ease server load.
Here is their demo video of it, from WAAAAY back when when they first put it in.
