The Big Bang Theory Origins of the Universe

The Big Bang Theory stands as the leading explanation for the origins of the universe. It proposes that the universe began as an infinitely small, hot, and dense point approximately 13.8 billion years ago and has been expanding ever since. This theory encompasses a wide array of concepts from cosmology, astrophysics, and quantum mechanics, detailing the evolution of the universe from its earliest moments to its current state. Understanding the origins of the universe through the Big Bang Theory involves both observational evidence and theoretical models, which explain the processes that shaped everything from the formation of elementary particles to the creation of galaxies and stars.
