New Study Findings on Galaxy Rotation

  • New study found universe might be spinning
  • Researchers examined 263 ancient galaxies to determine rotation direction
  • 2/3 of galaxies rotate opposite direction to Milky Way (marked blue)
  • Only 1/3 rotate same direction as Milky Way (marked red)
  • Result contradicts expected 50/50 probability distribution

James Webb Space Telescope Observations

  • Mission: look for early galaxies formed few hundred million years after Big Bang
  • Surprise finding: galaxies grow/develop structures much faster than dark matter hypothesis predicted
  • Supported modified Newtonian dynamics prediction instead
  • Current spinning discovery was unpredicted by any theory

Galaxy Formation Physics

  • Galaxies spin due to angular momentum conservation
  • Form from matter with increasing density via gravity
  • Matter has random motion, creating angular momentum
  • Like figure skater: denser matter = faster rotation
  • Random initial motion should produce equal probability of rotation directions

Validation of Results

  • Asymmetry not close to 50/50 - significant anomaly
  • Earlier studies on older galaxies showed similar but smaller asymmetry
  • Previous results largely ignored due to smaller effect
  • Combined data suggests asymmetry was larger in early universe
  • Different instruments found similar results, making observational bias unlikely

Possible Explanations

  • Universe-wide spin: Early universe matter had large-scale spin affecting smaller systems
  • Plasma misunderstanding: Incorrect assumptions about early universe plasma formation
  • Fractal universe theory: Quantum fluctuations with self-similarity patterns
    • Julia set example: fractal full of spirals all turning same way
    • Could explain large supergalactic structures violating cosmological principle
