We Finally Measured How Big the Laniakea Supercluster Is

Описание: We finally understand the true scale of the Laniakea Supercluster — and the answer reshapes our place in the universe. For years, astronomers believed the Virgo Supercluster was our cosmic home. But when scientists began mapping galaxy flows instead of positions, a hidden structure emerged: the Milky Way belongs to a much larger gravitational basin spanning more than 500 million light-years.

In this journey, we explore the invisible architecture of the universe. Watch how galaxies drift like streams in a cosmic river, how peculiar velocities reveal unseen currents, and why Laniakea is not a cluster of galaxies, but a continent of gravity stretching across the local universe.

We cover:
• The discovery of galaxy flow fields
• The Great Attractor and the Shapley Concentration
• The cosmic web and filament structures
• The Local Group’s slow drift toward Virgo
• What lies beyond Laniakea — and why some galaxies escape its pull
• The unanswered question: what happens when a supercluster collapses?

Sleep On Science creates calming, long-form documentaries that blend scientific concepts with cinematic storytelling. Our videos are designed for relaxation, late-night curiosity, and falling asleep while learning. We explore the universe at a slow, peaceful pace—covering astronomy, cosmology, space travel, deep time, and the quiet mysteries of existence.

Many viewers use Sleep On Science for bedtime, meditation, background study, or stress relief, returning to our channel as part of their nightly routine.
