The Great Attractor: The Cosmic Force Moving Galaxies | Cosmos in a Pod S1E21

Welcome back to Cosmos in a Pod! I’m your host, Amitesh, and today we’re diving into the mysteries of the Great Attractor—a gravitational anomaly pulling entire galaxies, including our Milky Way, across the universe at astonishing speeds. What is this enigmatic force, and how does it shape the cosmos on a massive scale?

Episode Highlights:

The Discovery of the Great Attractor

  • Astronomers in the 1970s and 1980s discovered the Milky Way and nearby galaxy clusters moving at 600 km/s relative to the cosmic microwave background.
  • This motion pointed to a massive gravitational pull from a region 150-250 million light-years away, hidden in the Zone of Avoidance.

What is the Great Attractor?

  • A gravitational anomaly in the Laniakea Supercluster influencing the motion of over 100,000 galaxies.
  • Difficult to study directly due to the obscuring plane of the Milky Way, but observations in infrared and X-ray wavelengths reveal some of its hidden structures.

Cosmic Flow: The Motion of Galaxies

  • Galaxies are interconnected through a cosmic web of filaments and clusters, and their motion is influenced by massive gravitational focal points like the Great Attractor and the Shapley Supercluster.

The Role of Dark Matter

  • Dark matter likely constitutes much of the mass driving the Great Attractor’s gravitational pull, shaping galaxy motion across the universe.

Unanswered Questions

  • What lies at the center of the Great Attractor?
  • How does it interact with larger structures like the Shapley Supercluster?
  • What can it reveal about the nature and distribution of dark matter?

The Future of the Great Attractor

  • The cosmic tug-of-war between gravity and dark energy will determine how the Great Attractor’s influence evolves over billions of years.

The Cosmic Perspective The Great Attractor is a powerful reminder of the vast forces that shape our universe. By studying it, we uncover the hidden connections between galaxies and the role of dark matter in the cosmos.
