Approximately 13.8 billion years ago, the universe originated from a singularity, swiftly expanding and cooling to create the matter and energy.
A brief period of exponential expansion after the Big Bang, where the universe grew at a mind-boggling rate, smoothing out irregularities.
As the universe cooled, atoms formed, leading to the creation of hydrogen and helium, the building blocks of stars and galaxies.
Nuclear reactions created the lightest elements (hydrogen, helium, and trace lithium), setting the stage for star formation.
Gravity began pulling matter together, forming clouds of gas and eventually leading to the birth of stars and galaxies.
Over billions of years, stars and galaxies emerged, grouped together, and evolved, ultimately defining the cosmic structure.
