Star and Galaxy Formation in the Early Universe

The video tutorial explores the formation of the universe from the Big Bang to the creation of stars and galaxies. It begins with early universe cosmology, explaining how energy condensed into matter, forming hydrogen and helium. The role of gravity in shaping the universe is discussed, leading to the formation of gas clouds and nebulae. The process of star formation is detailed, from protostars to nuclear fusion. Finally, the video covers the formation of galaxies and the universe's evolution into its current form.

What happens to a gas cloud when it exceeds the Jeans mass?

How does nuclear fusion contribute to the birth of a star?

In what ways do stars influence their surrounding environment after formation?
