Tiny Black Holes Might Have Left Holes in… Everything

Traditional Black Hole Theory vs. Current Data

  • Physicists previously identified 2 types of black holes:
    • Stellar mass black holes: formed from collapsed stars, few times mass of sun
    • Supermassive black holes: seeded by early universe star collapse, grow by consuming stars/gas/other black holes, up to billion times sun's mass
  • Current data challenges this theory:
    • Gravitational wave detections show stellar mass black holes much heavier than expected (up to 10x factor)
    • Computer simulations: supermassive black holes haven't had time to grow to observed sizes
    • James Webb Space Telescope: more big black holes in early universe than predicted

Primordial Black Holes Formation

  • Only 2 known natural black hole formation conditions:
    • Star collapse
    • Fluctuations in super hot/dense plasma of early universe
  • Primordial black holes: formed from early universe plasma "soup" density fluctuations
    • Could be any size
    • Existed before first stars
    • Candidate for dark matter explanation

Dark Matter Connection Issues

  • Dark matter comprises 80% of universe matter
  • Would require enormous number of primordial black holes
  • Expected observable consequences not detected:
    • Light flashes from evaporation (smaller masses)
    • Gravitational lensing effects
    • Star collapses from black hole passages
  • Theory unpopular due to lack of supporting evidence

New Research Paper Findings

  • Calculations for consequences of small black holes passing through objects:
    • Asteroids, planets, people
  • Large black holes: might hollow out planet/asteroid cores by getting trapped and consuming material
  • Small black holes: create tunnels through objects
  • Scale example: 10 microgram mass black hole = 10^-35 meter diameter
  • Tiny black holes effects:
    • Too small to attract atoms
    • Won't slow down or get trapped
    • "Stellar acupuncture" - not fatal to humans
    • Minimal impact on brain function

Detection Methods Proposed

  • Look for sudden holes appearing in materials
  • Larger black holes might cause earthquakes with moving epicenters
  • Moon-based detection potentially more effective than Earth
  • Paper missing consideration of sensitive particle detectors
  • Previous searches in old stones found no tracks
