Cosmic Reionization Era mysteries that turned the dark universe transparent

What happened after the Big Bang to flip the cosmic lights on? This video dives into the universe’s teenage years, when the first stars, galaxies, and black holes reshaped everything. We explore 25 open puzzles that still challenge astronomers, from first light to the last neutral gas.

What ignited the first stars and galaxies, including the hunt for elusive Population III stars and the role of dark matter halos
When reionization really happened and why CMB data, quasar spectra, and galaxy counts still disagree
Who did the work, dwarf galaxies or quasars, and how ionizing radiation escaped into intergalactic space
How patchy reionization was, what the 21-cm signal can reveal, and why temperature and helium matter
What JWST, future radio arrays, and local dwarf galaxies tell us about the end of reionization and its lasting impact
