✨Objects crossing the event horizon of a black hole appear to freeze in time.
🌟Light emitted from objects crossing the event horizon becomes redshifted and eventually disappears.
🚀Einstein's theory of general relativity also predicts the existence of white holes and parallel universes.
🕐Time appears to slow down for objects approaching the event horizon.
🌌Black holes can be detected by observing the dimming and redshifting of light emitted from objects crossing the event horizon.
