Which consequence occurs when intense gravitational time dilation nears a black hole's event horizon?

💡 Explanation

Near a black hole, extreme gravity causes dramatic time dilation; space-time curvature becomes immense, causing the gravitational redshift of outgoing photons. Because of the Einstein equivalence principle, light loses energy escaping this intense gravitational field; therefore emitted wavelengths observed become stretched, rather than blue-shifted or unaffected.
