Definition

1. Noun:
   • A massive concentration of galaxies: The Great Attractor is a vast, diffuse gravitational anomaly in intergalactic space, located in the direction of the constellations Centaurus and Hydra.
   • A gravitational focal point: It is characterized by its immense gravitational pull, which influences the motion of many galaxies, including our own Milky Way, over vast cosmological distances.

Usage Examples

• Noun:
  • Astronomers study the Great Attractor to understand large-scale flows in the universe.
  • The motion of our Local Group of galaxies is influenced by the pull of the Great Attractor.

Advanced Usage

• "the pull of the Great Attractor": refers to its dominant gravitational influence on galactic motion.
  • Scientists map galaxy velocities to trace the effects of the pull of the Great Attractor.
• "in the direction of the Great Attractor": describes the spatial orientation toward this anomaly.
  • Many galaxies are streaming in the direction of the Great Attractor.

Variants and Related Words

• Gravitational anomaly (n): a region in space where the gravitational force is significantly different from the surrounding area.
• Large-scale structure (n): a vast formation of matter in the universe, such as a supercluster or filament, of which the Great Attractor is a part.
• Dipole repeller (n): a complementary cosmological concept describing a region of relatively low density that also affects galactic flows.

Synonyms

• Gravitational focal point: A center of gravitational attraction.
• Mass concentration: A region containing a large amount of mass.

Related Phrases

• Flow toward the Great Attractor: The bulk motion of galaxies drawn by its gravity.
  • The Milky Way is part of the flow toward the Great Attractor.
• Hidden behind the Zone of Avoidance: A phrase noting that the Great Attractor's core region is obscured from our view by dust and stars in the plane of our own galaxy.
  • The core of the Great Attractor remains difficult to observe because it is hidden behind the Zone of Avoidance.

Noun

1. a massive grouping of galaxies in the direction of Centaurus and Hydra whose gravitational attraction is believed to cause deviations in the paths of other galaxies
