← ScienceWhich consequence results when extreme spacetime curvature traps light?
A)Formation of an event horizon✓
B)Increased gravitational redshifting observed
C)Decreased electromagnetic radiation emission
D)Spatial dimension inversion occurs locally
💡 Explanation
An event horizon forms because immense gravitational fields cause spacetime curvature. Objects falling past escape velocity cannot return due to spacetime curvature; therefore, an event horizon defines the black hole's point of no return, rather than increased redshift alone.
