Summary of La Teoría del Big Bang: el Origen del Universo 🌌

00:00:00 - 00:10:00

The Big Bang theory is the most widely accepted theory for the origin of the universe. It states that the universe began with a violent explosion about 13.8 billion years ago. All matter, time, and space sprang into existence at that moment. The theory has been confirmed by numerous observations, including the observation that distant galaxies are farther back in time than nearer ones.

• 00:05:00 The video discusses the three stages of the universe according to the Big Bang theory- the radiation stage, the cosmological stage, and the structure formation stage. The radiation stage is characterized by the creation of photons, the cosmological stage by the dominance of matter, and the structure formation stage by the formation of stars and galaxies. The video points out that the high temperatures of the early universe did not allow light to form, but that the universe had cooled enough by the time light could move freely to allow the formation of neutral hydrogen. The video concludes that the universe has an origin in time and a finite age.
• 00:10:00 The video discusses the theory of the big bang, which scientists believe is responsible for the expansion of the universe. The expansion has not stopped, on the contrary it seems to have accelerated, and evidence for the theory can be found in the cosmic radiation background. The Hubble-Lemaitre law states that the speed of galaxies away from us is proportional to the distance between them, and has been validated by the Hubble Space Telescope. However, there are still many questions that scientists are unable to answer about the theory, such as the origin of the singularity and why matter predominated over antimatter.
