Hawking Radiation
Theoretical radiation emitted by black holes due to quantum effects near the event horizon.

💡 Analogies
Imagine a black hole is like a hot cup of coffee in a cold room. Very slowly, it radiates heat and eventually goes cold. Hawking showed that black holes, despite being "black," actually glow faintly and lose energy over time.
Think of the empty space near a black hole like a churning sea of tiny bubbles constantly appearing and vanishing. Occasionally, one bubble escapes while its partner falls in. Over eons, these escaped bubbles drain the black hole.
⚠️ Common Misconceptions
Myth: Hawking radiation has been directly observed from real black holes.
Reality: Hawking radiation from astrophysical black holes is far too faint to detect with current technology — the temperature is billionths of a degree above absolute zero for stellar-mass black holes. It remains a theoretical prediction, though analog experiments in laboratories have demonstrated similar physics.
