This is not the series of the Matrix movie, but a real theory from the scientific community that our dearly damn universe may be a computer simulation. In other words, everything in the universe and the whole universe itself are all simulated!
If the universe is simulated, who or which has created this simulation? Religious persons will say their respective God/s, but why such a supernatural being would do such a thing? Is this a test? Does it mean a Deity or more created something to see how it goes, or, even, created it and abandoned it later?
Even a simulated universe cannot be proven, it does involve the question of the existence of an intelligent design! Bear in mind, God, Deity or whatever you call it is not the same for everyone. As more people are abandoning religions because of several absurdities, they prefer to adopt spirituality as the latter does not share the same view on a God. For example, many think God or Deity is a supernatural energy. It can be a being, but we do not know. Thus, we cannot give it characteristics just like religions do. In the same line of thought, spirituality does not have big issues with science compared to religions.
Imagine you are a programmer, and you create a simulation software. You created it in such a way that it does not need your intervention. You added all the features, so that the simulation is governed by them. Apply this to the concept of a Creator. Hence, the simulation software is the universe, the features are the laws of Physics and energies. Not all people will agree to this hypothesis, because the Deity created it and not interfere. It sounds a bit senseless, why the Creator would not intervene in its own creation?
Nevertheless, it can be that a Creator created the universe which does not require its interventions! The Creator gave us logic and feeling to determine what is right and wrong and what to do for our own progress! Let’s go deeper in the topic, suppose truly the universe is like a computer simulation, does it mean the whole universe itself is not real? Does it mean every living being, planets, galaxies, stars etc are just illusions? Well, it can be! Just see around you, do you think we are real? You are real in your own reality but not for the Creator of everything!
We can ask more questions whether another universe exists! The theory of multiverse should be taken more seriously because we cannot deny we have other universes as well. The question of parallel universe should be immensely studied. If the universe is a computer simulation, does it have any bug just like a real software? Will the simulation stop one day? In case it stops, will it simulate again? So much mysterious aspects in this matter!
The more science is progressing, the more we are near to an answer even we do not have concrete evidence. We are decoding new mysteries everyday. It is crystal clear we are not alone in this simulation. Our galaxy contains billions of planets similar like us, now imagine, the number of galaxies with their trillions and trillions of planets. Yes, there are other civilizations elsewhere. Let’s see what new improvements will occur in this theory. Even you believe it or not, it is true the universe is being simulated and it is not necessary to believe in a Creator or not to know that!
A last thing to this theory, some Physicists have decided to reproduce the universe on computers, in proper term, to create a universe and simulate it.
