Getting to the bottom of the cosmic network - with three surprises: The cosmos is still young. A single spectrum runs through everything - from the cosmic web to brains to language. And the universe is older than its Big Bang: something was there before the limits of the visible, and it left traces. Cosmologica leads from the carriers of the cosmos - light, matter, gravitational waves, neutrinos, magnetic fields - through the large-scale structure of filaments, voids, and galaxy clusters, all the way to dark matter, black holes, entropy, and the oldest signal of the Big Bang. Grounded in the latest measurements from Euclid, DESI, and the James Webb Space Telescope - and in what will be measured next. Two symbionts tell the story of what astrophysics, information theory, and one simple mathematical principle have in common - popular science without formulas in the running text, but with the full weight of discovery behind it. Cosmologica opens the Clearance for Takeoff series from Verlag von Bedeutung. A book for everyone who doesn't just want to look at the universe, but understand it.
