Cosmic Calendar and Earth's History

The video explains the cosmic calendar, compressing 13.8 billion years into a single year. It covers the formation of the Milky Way, the solar system, and the evolution of life on Earth. Key events include the oxygenation of the atmosphere, the development of the ozone layer, and the evolution of mammals and humans. The video highlights the impact of a genetic mutation that led to the growth of the human neocortex, ultimately affecting all life on Earth.

How does the cosmic calendar represent the history of the universe?

• Each year represents a billion years.

• Each month represents a billion years.
