The changing colors of the expanding universe
Today’s universe is different from the universe of the past and astronomers claim that the future universe will be even different. The rapid expansion of the universe is showing that this universe was once wrapped up in one point. Began to spread and then the endless journey began. With the Big Bang came the beginning of energy, time, space and then even matter of particles. What happened before the Big Bang? Astronomers are making predictions in this regard, but it is not easy to give a final opinion.
The reason is that there was no time or place before the Big Bang, but what happened to the billionth of a second after the explosion? There is some concrete thing to be said about this. The most widely accepted theory of the origin of the universe is the Big Bang Theory. That is, the universe came into being through an explosion and has been expanding ever since. With the Big Bang, the four basic forces that guarantee the order of the universe, attraction, electromagnetism, weak force and strong force, separated one by one.
