← ScienceWhich outcome occurs when gravity exceeds tidal forces in a galaxy cluster?
A)Gravitational lensing distorts background objects✓
B)Star formation exhibits a cessation phase
C)Galactic spin rates undergo rapid increase
D)Black hole mergers happen with decreasing frequency
💡 Explanation
Gravitational lensing occurs because extreme mass warps spacetime, creating curvature that bends light; this is caused gravitational forces overwhelming weaker tidal effects. Therefore, we perceive distortions rather than alternative effects because stronger self-gravity dominates tidal influences.
