Question

Which description is considered most accurate regarding what actually happened during the Big bang

Answer 1

The most accurate description of what actually happened during the Big Bang is that approximately 13.8 billion years ago, the universe began as a singularity - an infinitely dense and hot point from which all matter and energy originated. The universe rapidly expanded and cooled, forming the building blocks of galaxies, stars, planets, and ultimately life as we know it today. This event marked the beginning of time and space as we understand it.
