Stars, galaxies, black holes...For 13.8 billion years, light has been related to all things, it shapes the largest structures in the universe. Born in the chaos of the Big Bang, she remained a prisoner of matter for a long time, until the day when, finally, she illuminated the cosmos with her first brilliance.

Light wanders alone in an immense and cold Universe. Indifferent, he expands and wins. But she perceives an invisible presence lurking, secretly weaving, through the cosmos, a mysterious web that traps matter. Then, everything changes: light takes hold of this matter, sets it ablaze and rewrites its destiny.

At the cosmic dawn of the Universe, light shapes the first stars, veritable forges which give birth to the first complex atoms. But these stars, too fragile, were born to die. From their ashes a new generation of stars will soon be born which will form even brighter structures: the first galaxies.

The Universe is running out of steam. Galaxies have burned matter and exhausted space. The Light wakes him up and leads the stars in a frantic dance. Little by little, cosmic noon is announced, a golden age where, in abundance, stars are born and galaxies flourish.

The vast symphony of the Universe unfolds. The light dances with the galaxies which take on a spiral dress. But, here and there, more and more, the stars jostle. The Universe is too populated. Galaxies collide, become exhausted and die. However, these galaxy cemeteries remain among the brightest structures in the cosmos...

Light discovers terrible specters in the shadows of the cosmos: ancient stars who invent a new destiny: black holes. In front of them, the light flickers. Nothing escapes their intense gravity, not even its photons. Yet, against all odds, light finds powerful allies in them.

The light plunges into a black hole. Absorbed by the abyss, beyond the event horizon, she glimpses the destiny of the Universe: the death of stars, galaxies, and black holes which, little by little, evaporate. What remains of the Universe, billions and billions of years after the Big Bang? Could this be the start of a new cycle?

On a distant pebble, nestled in the heart of a young spiral galaxy, light discovers the tiny and fabulous spark of a new day. Life, one of the most luminous forms in the Universe, proliferates there, a fragile breath which nevertheless seems to want to dominate the one that nourishes it...
