Foto del Big Bang (la Luz Más Antigua del Universo)

The video explains cosmic background radiation, originating from the Big Bang, and its journey through the universe. Initially, the universe was dense and hot, with free electrons and protons. As it expanded and cooled, electrons and protons formed hydrogen atoms, making the universe transparent and allowing light to travel freely. This light, now stretched into microwaves, is known as the cosmic microwave background (CMB). The video also discusses quantum fluctuations that led to the formation of cosmic structures like galaxies and superclusters.

What is the significance of the cosmic background radiation in understanding the universe?

Describe the conditions of the universe immediately after the Big Bang.

How did the formation of hydrogen atoms affect the transparency of the universe?

Explain the relationship between the cosmic microwave background and the temperature of space.

What do the fluctuations in the cosmic microwave background tell us about the early universe?
