The theory of everything is the holy grail of modern physics. As science developed, scientists discovered more and more levels of knowledge of matter. Newton discovered the law of universal gravitation, and we used this law with success for several centuries, until Einstein formulated the theory of relativity. It turned out that Newtonian physics is a special case of Einstein's physics. However, the application of the new theory opened up limitless horizons in practical application! This includes semiconductor electronics, GPS and thousands of new materials and technologies. Now the time has come for new physics, which will penetrate to a new level, and what it will give in practical terms is difficult even to imagine! Perhaps the theory of everything will open the way for us to the stars and even other galaxies, or it will allow us to manipulate matter and energy at the level of God, who knows?

I, of course, am not a scientist and am not even fond of natural sciences, but I can say the following. An analogy can be drawn with our own life of each individual person. Each day we live, depending on what we do, with whom we communicate, fits into the framework of a certain behavior model. We do one thing on Monday, another on Sunday, a third in September, and a fourth in the spring. At the same time, we have a past, our personal experience, we know where we came from, there is also the present and we make plans for the future. In other words, we live separate moments, but in the end a whole picture is formed - our life, and we are relentlessly trying to understand its essence as a whole - to find a purpose or meaning.

The same is with all of humanity and the whole world ... Each individual person is one grain of sand, one drop. By ourselves and for ourselves we imagine something, but on the scale of the entire population of the Earth, each person is like one day in our life. And we only make sense if we are all together, which is why it is so important to know the past, present and future. Each person, each inanimate object obeys its own specific laws of physics, but all together in the aggregate obeys some one global law, otherwise we would not be able to exist and develop in harmony. At the same time, private laws cannot contradict global ones.

Planet Earth is also only a grain of sand in the entire galaxy. And it also obeys the laws of an even larger system. Finding and formulating a theory of everything can explain how the Earth arose from its very origins and what awaits us in the future. I think this theory definitely exists. Because if it did not exist, the world would be in chaos, and we would not be here.
