30 Theories About the Universes Dark Ages - First Halos Form - A Cozy Celestial Story

Описание: What Really Happened During the Universe’s Dark Ages?

Imagine the cosmic microwave background fading into silence, leaving behind a universe of perfect darkness. No stars. No galaxies. Only vast clouds of hydrogen and helium adrift in an expanding void. This is the era astronomers call the “Dark Ages” — a hidden epoch stretching hundreds of millions of years after the Big Bang, when the cosmos had cooled, but light had not yet returned. In this haunting stillness, the invisible scaffold of dark matter began shaping the first hints of structure, setting the stage for everything that followed.

The standard cosmological model tells us these were the years between recombination and the birth of the first stars. Within that darkness, dark matter halos formed, molecular hydrogen struggled to cool the gas, and ultraviolet radiation from the first stars began the long process of cosmic reionization. From there, scientists have built thirty mind-twisting theories — from primordial black holes and cosmic strings to axion clouds and mirror universes — each trying to uncover what forces sculpted the dawn of light.

The Dark Ages may seem remote, but they hold the keys to understanding why the universe looks the way it does today, and perhaps even why we exist at all.

Join us as we explore these thirty theories and trace the moment when darkness gave birth to creation itself.
