13.8 billion years ago, everything that exists emerged from a singularity of infinite density and temperature. Big Bang is Aeon Immersive's focused, immersive exploration of the universe's first moments — from the Planck epoch through the quark-gluon plasma era, the formation of the first protons and neutrons, and the nucleosynthesis of hydrogen and helium in the universe's first three minutes.

Where Origin of Universe covers the full cosmic timeline, Big Bang zooms in with extraordinary detail on the first fraction of a second and the crucial first 380,000 years — the period that set the initial conditions for everything the universe would become. It covers the Higgs field, cosmic inflation, baryogenesis, and the recombination era, visualising processes that are fundamentally invisible and sub-microscopic at a scale only the dome format can provide.
