The origin of the universe

The video explains the evolution of the universe from the Big Bang, which occurred 15 billion years ago, leading to the formation of matter, energy, space, and time. Initially, the universe was a hot, dense gaseous state that expanded rapidly. Over billions of years, hydrogen and helium formed, leading to the creation of galaxies, including the Milky Way. The solar system, including the Sun and Earth, formed about 10 billion years after the Big Bang. Life on Earth began to appear around 12 billion years after the Big Bang, eventually leading to the planet's current form.
