The idea that the universe began from a single point and expanded to its current size explains a large number of observations, i
ncluding those in the table below. In addition, many predictions based on the idea have led to additional observations that support it. This idea of the origin of the universe is best classified as a
The description of the question provided above points out to the famous Big Bang Theory. In addition, this theory is among the most accepted by cosmologists because it fits like a glove to the phenomenon the universe is experiencing right now: it is expanding and distances between celestial bodies are getting farther and farther.
The origin of universe is best classified by the Big bang theory. This theory proposes that the universe is very old and its origin took place almost 20 billion years ago. It states that a single huge explosion i.e. Big bang took place in the space which was so powerful that it is unimaginable in physical terms. Due to this explosion, the universe expanded in volume and the temperature of the space came down. Slowly hydrogen and helium gases formed, which condensed due to the gravitational forces present in the surroundings. This all resulted in the formation of billions of galaxies.
