New fear unlocked: runaway black holes
- Runaway black holes could travel across galaxies at speeds reaching thousands of kilometers per second.
- Gravitational wave observations have revealed spin angles that support runaway black hole scenarios.
- James Webb Space Telescope images show straight stellar contrails in distant galaxies that may indicate runaways.
- Contrails could form as a runaway black hole travels, pulling gas and forming new stars in its wake.
- Some dogs: smaller runaway black holes are expected to exist alongside their massive counterparts.
- Runaway black holes could, in theory, move at speeds that avoid typical galactic orbits.
- Observers have correlated streak-like features with the passage of a black hole through a galaxy.
- The potential for a solar system–intervening runaway black hole remains extremely unlikely.
- The research integrates theory with multiple observations since gravitational wave discoveries began in 2015.
- The study highlights a broader universe where runaways affect star formation and galactic dynamics.
