The Big Bang: A Point Where Space and Time Vanished
In short: Modern science points to the Big Bang as our origin story, but it leaves a profound mystery: what existed before the very first moment of space-time?
The Big Bang theory suggests that approximately 13.8 billion years ago, the universe emerged from an extremely hot, dense state. This initial state is often described as a singularity—a point where mass and energy density become infinite while dimensions shrink to zero. Crucially, this wasn't an explosion occurring within space; it was the birth of space itself.
As the universe expanded, it cooled rapidly, allowing subatomic particles to form and eventually leading to nuclear reactions that created hydrogen and helium. Gravity then pulled these atoms together over hundreds of millions of years to form the first stars and galaxies. The central scientific tension remains: what preceded this singularity or triggered its initial countdown?
