What Is Dark Matter, Exactly? | Science for Sleep

Описание: Tonight, we drift gently into one of the quietest questions in modern cosmology: what fills the universe when light falls silent? In this episode, we explore dark matter not as a mystery to solve, but as a presence to understand — calm, invisible, and shaping everything we see. Galaxies turn smoothly, clusters remain bound, and cosmic structures endure, guided by gravity we can measure but matter we cannot see. This is a slow journey through observation, evidence, and patience, following how scientists came to recognize an unseen majority of the universe.
This is AstraFlow, where learning softens into rest and curiosity becomes calm. Here, science for sleep unfolds without urgency, allowing the mind to settle as understanding deepens. Let the steady rhythm of science for sleep guide your breathing, as science for sleep carries you through space, time, and gravity. In this quiet exploration, science for sleep becomes a place to rest, and science for sleep becomes a way to drift peacefully into the unseen structure of the cosmos.
