Galactic Epoch

Galactic Epoch produces documentary-style educational videos on cosmology and astrophysics, with recurrent deep dives into dark matter and dark energy, black holes (their formation and observational signatures), star formation, and the physics of the early universe. The channel ties these topics to contemporary observations — notably James Webb Space Telescope discoveries — and occasionally examines related ideas like technosignatures or astroengineering (e.g., infrared signatures of Dyson-like structures).
