Are We Living in a Computer Simulation?

 For a while around world coming theory that we are living in a computer simulation.

Simulated reality is the hypothesis that reality could be simulated—for example by quantum computer simulation—to a degree indistinguishable from "true" reality. It could contain conscious minds which may or may not be fully aware that they are living inside a simulation.

Simulation is the imitation of the operation of a real-world process or system. The act of simulating something first requires that a model be developed; this model represents the key characteristics, behaviors, and functions of the selected physical or abstract system or process.

According to a new study by astrophysicists from Oxford University, the likelihood that we exist in a simulated universe becomes practically impossible under normal quantum circumstances. They realized that to accurately model quantum phenomena occurring in metals, a simulation needs to be extremely complex. The complexity increased exponentially as the number of particles required for full-bore simulation grew. The larger the simulation, the greater the computing power required. In short, it’s always unworkable. It’s physically impossible — and they only attempted to model a portion of the physical universe.  

It's not enough evidence we living simulation. It's more sense and proof for the fact we live in real life.

We will not find proof that we are not living in a simulation, because any evidence we get can be simulated. Some argue that the existence of habitats, or regions around planets in which life may exist, is evidence supporting the theory of simulated reality.

The Matrix is not fiction? Other scientists say that we probably live in a simulation. Researchers analyze Nick Bostrom's hypotheses and try to calculate the probability that our life is a computer simulation. Some even have a risky idea of how to prove - you have to cause a computer error and hang the system. Others say that you just need to wait because soon it will be the man who will start creating simulations of reality.

Do we all live in a computer simulation and our reality is an illusion like in the Matrix movie? Or maybe we're all stuck with Mikoshi from Cyberpunk 2077? In 2003, the philosopher and futurist Nick Bostrom of the University of Oxford in the article "Are You Living in a Computer Simulation" stated that "our life is a simulation dreamed by an advanced civilization". He stressed that at least one of the following three propositions about our world must be true.

The Mandela Effect - memory problems or parallel reality and reality simulation?

Some refer to the "Mandela Effect" to prove the existence of a simulation. Why do we remember things that we did not live through? Why do the same memories apply to so many people? Conspiracy theories assume that it is not only the imperfections of the human mind but evidence for the existence of parallel realities. What if this is really part of the simulation and the "programmer" is misleading us? Or is it the "system error" mentioned by Caleb A. Scharf? Or maybe by imagining something that was not there, we are already starting to create some reality simulations ourselves?
