The Early Universe

The early universe discussed the first three minutes after the big bang and explained the process responsible for the formation of atomic materials. If t = 0, there is no space or time. Today's popular theory describing the origins of the universe and the places where it began is Big Bang theory. Scientists believe that the universe we had around 14 billion years ago can be in the palm of people. At first there is nothing. I do not have space or time, but then it is bright. There was a small amount of light, and there was space in this little fireball - this is the beginning of time.

Immediately after the Big Bang, the universe was in a uniform and dense state at an early stage. Hot gas in the early universe approached thermodynamic equilibrium (causing horizon problems), hence the maximum entropy state when considering their volume. However, expansion of the gas increases its entropy, so expansion of the universe increases entropy. From the later age, the early universe can be thought of as very orderly. The theory of cosmic expansion explains the homogeneity of the state near this initial equilibrium

As the universe grows older, it varies from minimum entropy to maximum entropy, and range of sizes. This results in a state homogeneity close to the initial equilibrium, which increases with time as the entropy increases. Therefore, the local universe begins to become a uniform dense state at its early stage, and at the final stage it becomes a random low density state. After all, as all grows late, the older the universe, the longer its process. Each universe starts with a small disturbance of tightly packed raw materials. After the universe expanded rapidly, it started to expand, and everything that was not bound by its internal gravity was pressed more and more strongly. After all, everything in the universe is too far and there is nothing else to do, so all of the space-time continuum will eventually do not do anything. Then, after the end of one universe, the other begins

About 1.75 billion years ago, our universe was born. Shortly thereafter, primitive rays began to fly towards the universe and spread throughout the early universe. At this moment, the universe itself is expanding. After the first occurrence, the expansion of the universe slowed down, but since then the expansion rate steadily increases due to the dark energy. Essentially, the universe has grown at an increasing rate since its birth. Cosmologists estimate that the oldest photons we observed since the Big Bang spread between 4.7 and 4.7 billion light-years. This means that you can observe the universe with a width of about 93 billion light years (giving or needing a few light years).
