Question

In three to five sentences, briefly describe how the big bang theory explains the origin and evolution of the universe.

Answer 1

The Big Bang Theory posits that the universe originated from an extremely dense and hot state, around 13.8 billion years ago. This event, known as the Big Bang, marked the beginning of space, time, and matter as we know it. As the universe expanded, it cooled down, allowing particles to form, and eventually leading to the formation of galaxies, stars, and planets. The theory also suggests that the universe is still expanding, supported by observations such as the redshift of distant galaxies and the cosmic microwave background radiation.
