Black Holes: The Unseen Universe

Singularity: The point of infinite density at the center of a black hole
Event Horizon: The boundary beyond which nothing can escape, not even light
Hawking Radiation: Theoretical phenomenon of black holes emitting energy over very long timescales
Gravitational Waves: Ripples in the fabric of spacetime caused by massive objects like black holes
Supermassive Black Holes: Black holes with millions or even billions of times the mass of the Sun
Accretion Disk: Swirling disk of gas and dust surrounding a black hole, heated by friction and ultimately falling in
Tidal Forces: Intense gravitational forces that can stretch and tear apart any object venturing too close to a black hole
