Is this world real? When you hear such questions from a person, then you wonder what kind of a man is he who is putting a question mark on the existence of the world, but only when you put a question mark on something, then you get the real answer.
When someone says that this world is fake then what comes in your mind. There may be some other meaning in your mind, but the real thing is that this world exists. This is true because for this universe to be faked, it is necessary to have this world. If you consider this universe to be a box which is a container and consider the things inside the box as the stars and planets of the real universe, then the thing is that this box is real. Means the container or the universe is real, but the things inside this universe like the planet, stars, humans and animals, are they real.
Let us understand this with an example. Your mobile or computer cashew screen. If you look at that screen carefully, you will notice that this screen is made up of small elements which we call pixels. These pixels work together and change their color every second, which makes you feel like you are watching a video on the screen. But what you see in the video, it is the wonders of pixels. The movie you see in mobile, it looks absolutely real, but that is also the magic of pixels' dance. That means the screen and the pixels are real but the scene you see is just an illusion. Pickles behave in such a way that you think that a scene is going on, but in reality only the pixels of that scene are real and what is seen is fake. Because if there are no pixels, then there will be no video.
If we apply this concept in the universe, then a big interesting thing comes out. This is called matrix or simulation concept. According to this concept, this world is also designed from a computer and if you look at it deeply, then you will find this thing absolutely true. You must have read in science that everything in this world is made up of electrons, protons and neutrons, then everything is made of these three things, and the way we talked about pixels, in the same way you can assume these three things as pixels. Because of the dance of changing the color of pixels, you feel like you are watching a video. In the same way, the movement of atoms in this world, all things are starting from there. The thoughts that are coming to your brain, are amazing of your brain neurons. You are able to understand these things due to the firing that is taking place between the neurons in the brain.
If we look in depth, the neurons of your brain are also made up of atoms. Because of firing between the neurons in your brain, thoughts come in your brain. Everything in our world is made of atoms. It means whatever is in this world is just atoms. You see collections of atoms as the world. In reality only atoms exist, what appears is illusion. At the fundamental level, only atoms exist or if there is anything smaller than atoms, then that thing exists. It is not that, nothing is smaller than atoms. There are quarks and many such particles which are smaller than atoms, but till date science has not been able to study those particles in detail. But who would have made these pixels or atoms, who would had programmed it? Yes, I said programming, can't it be that you are living in a computer world. If you are a computer programmer or hacker and know computer programming and coding then you will understand these things easily.
Computer games are a whole world inside themselves. A world created by game coders, how real that world looks like but not real at all. It is just a virtual world made from programming, it is a matrix or simulation concept. This concept says that this world is also a computer game. But the main thing is that if this world is a computer simulation, then there must be someone who made it. Perhaps an intelligent mind is behind this. Think that, how amazing it is, your heart is beating, Blood is running in your body, the earth is spinning, This is all happening automatically. But where did all these things start? There would be any first force existed in the universe which made the first atom. How and why the universe started, we get stuck on this question. No one knows what happened behind this.
Those who believe in the matrix concept believe that the someone who has programmed this world has set the parameters that we cannot know what is beyond it because the programming of this world does not allow it. Some people believe that the programming of this world is done by nobody else but your mind and you can change the codes of this world and hack them with the help of the power of your subconscious mind. If you keep thinking about something again and again, you may get that thing surely, you can call it the hacking of the subconscious mind of your mind, which is due to the law of attraction. How is this world, it depends on your mind. Nothing is fundamental. What is right for one person can also be wrong for another person. for example, If you like a game and your friend doesn't like that game at all, is this game good? Its answer does not really exist, because how is the mindset of a person's mind, depends on the person whether a particular person will like it or not. The kind of things your brain likes depends on the environment in which you have been living since childhood, so you can understand from it how life is playing games with you.
Perhaps only a few people believe in these concepts, but as technology will progress, perhaps we will be able to know the secrets of this world. Just as glitches occur in a computer program or game, there are probably a lot of glitches in this world too and maybe we feel it sometimes.
