Decoding the Nature of Reality
Is the universe real? Are we living in a simulation? Is the reality what we perceive to be real or if there is something more to it then what meets the eye? All these questions have been challenging physicists and conspiracy theorist all over the world for several decades. Ever since the dawn of quantum mechanics there has been debates about what the nature of reality actually is?

There is no denying the fact that quantum mechanics is true because it has been able to make many astonishing predictions to a great level of precision. Quantum physics will prove to be a cornerstone of technology in the years to come for example the semiconductors used in computers and other electronic devices is based on a quantum phenomenon called electronic band structure of solids. Even LASER is based on quantum phenomenon. There is an important concept in this field which states that a particle exhibits wave property and after observation its wave function collapse and the particle comes into existence. In other words, a particle does not exist unless it is observed but such a theory transcends all common sense yet the theory is believed to be valid. Neil Bohr called this “duality paradox” a fundamental fact of nature.
One such hypothesis for the explaining the nature of reality is “Simulation Hypothesis” . The great mathematician and philosopher, Rene Descartes first laid out its argument long before quantum mechanics was even established. This theory was later refined by Nick Bostrom who argued that the probability of us living in a simulated universe is much higher than the probability of us living in a real universe. This hypothesis had garnered the attention of several people over the years like Stephen Hawking, Elon Musk , famous astrophysicist Neil De Grasse Tyson and many more. According to this hypothesis we, all of the surrounding around us, the laws of physics and everything exist as a result of a simulation run by a higher sentient being. Now this is mind boggling but there is a possibility that it might be true.
Computer enthusiast and programmers even believe that we are inside a game which is run by a higher entity and that we are nothing but codes- 0’s and 1’s back and forth. A programmer builds a game using codes and games have evolved in the past 30 years and also the complexities of these codes have risen exponentially. Who would have thought that games would evolve from “Contra ” to “Witcher 3 ”. Games have evolved so much that in the near future the graphics used in the game would be almost same as that of the real world. But to exactly create and maintain a game just like the real world we would need almost infinite computational power which is impossible by even quantum computers having billions of qubits . Open world games like the “GTA ” series, “Just Cause ” series are good examples in which we can control the character and move him around and do all sorts of things with him just like in the real world. Now imagine that the character in the game was intended in such a way that all the character slowly evolves and they could start to think and rationalize and soon they could build their own games in which they create sentient beings of their own. Now the character will think that it has free will whereas its actions and thoughts are predefined. If this is to be believed that we cannot say for sure that we are or we aren’t living inside one of those games. We could never know where is the beginning of this chain or in which layer we are in. In small games to reduce the computational power, the program executes only those events in which the character of the game is interacting with or only those things exist which can be viewed by the character. All the other random generations do not execute at the same time so as to prevent the computer from getting lagged, also known as procedural generation .With this one can create a infinite procedural generated world even with non-infinite memory. Now this has resemblance with one of the quantum phenomena explained earlier (particles do not exist unless they are observed).
How can we be so sure that something exists? How can we be sure that “WE” even exists? Rene Descartes once said “We think therefore we are”. What if our thought is a part of a greater scheme, what if all of our thinking is merely an illusion, what if we are just codes? Is existence an illusion? Is it a question that can never be answered or will we get an answer to all the universal and metaphysical mysteries in the near future through scientific advancements?
