In the beginning, there was nothing, which exploded.

Explain quantum nothing
Our universe began as a point smaller than an atom. How small is that?… It might help to know that you could squeeze 1 million atoms into the dot at the end of this sentence.
- David Christian, Origin Story
At the moment of the big bang, the entire universe was smaller than an atom. Packed into it with all the energy, and matter present in today’s universe. All of it. That is a daunting idea, and at first, it might appear plain crazy. But all the evidence we have at present, tells us this strange, tiny, and fantastically hot object really existed about 13.82 billion years ago.

Huge amounts of energy were compressed into tiny amounts of matter, like motes of dust in a vast fog of energy.
- David Christian, Origin Story
In the seconds and minutes after the Big Bang, the universe was in thermodynamic free-fall. For a dazzling few moments, there was enough energy to make and unmake exotic new forms of energy and matter. In the kiln of the big bang, forces and particles stabilised like fired pottery.

Inconceivably hot and dense , it exploded outwards in an expansion that continues to this day more than 13 billion years later, and will continue for another X billion.
An explosion that never ended. Even after 13.8 billion years we’re still in the opening moments of the Big Bang. It will continue for trillions of years more, during which time gravity will have swallowed everything in the universe in the maw of gigantic black holes.
Within seconds of the big bang, a chaotic mess of bosons and fermions were created. Three minutes later, many of them coalesced into the most basic atoms, creating vast clouds of hydrogen and helium. These clouds floated in space for millions of years. Over a long time gravity pulled the clouds inwards, until they formed billions of swirling galaxies. Within each galaxy, clouds rotated around a central
Should I get into black hole cosmology? The theory where black holes could make a big bang, creating a child universe. Or the big bounce, where a black hole singularity could rebound, creating a big bang.
