Alternative History: Echoes of Architects
The Subtle Call My first acquaintance with this story was neither a dream nor a vision of a waking mind – rather a vivid, telepathic stream of images, words, and...

Gravitational clustering and density fluctuations
How slight density contrasts grew under gravity, creating conditions for stars, galaxies, and clusters to form Since the time of the Big Bang, the Universe transformed from an almost completely...

Emergence of large structures
From the heat-breathing beginnings of the Big Bang to the complex structure of galaxies and their clusters stretching across billions of light-years, the cosmic structure has undergone an astonishing evolution....

Regionalization: The End of the Dark Ages
How ultraviolet light from the first stars and galaxies reionized hydrogen again, making the Universe transparent In cosmic history, reionization marks the end of the Dark Ages — the period...

The Dark Ages and the first structures
The period before stars formed, when matter began to gravitationally clump in denser regions After the recombination epoch — when the Universe became transparent to radiation and the cosmic microwave...

Recombination and the first atoms
How electrons combined with nuclei, ushering in the "Dark Ages" in a neutral world After the Big Bang, the Universe was a hot, dense medium for the first few hundred...
