PAGE 1 OF 5 — WHAT IS A BLACK HOLE?
THE VOID
Comic illustration of a black hole event horizon, the boundary beyond which nothing can escape
WHERE GRAVITY WINS EVERYTHING
A black hole is a region of space where gravity is so unimaginably strong that nothing can escape once it crosses the boundary called the event horizon. Not matter. Not light. Not information. Not anything. It is not a hole in space. It is a real object of almost infinite density, born from the collapsed core of a massive dead star.
🤔 MYTH BUSTER
Black holes are not cosmic vacuum cleaners. They do not suck things in from a distance. If you replaced the Sun with a black hole of the same mass, Earth would continue orbiting exactly as it does today.
INESCAPABLE!
EVENT HORIZON
Diagram of the event horizon where escape velocity exceeds the speed of light
⬛ The point of no return: escape velocity exceeds light speed
⚡ Cross it and you can never come back
🐧 Invisible itself: only the shadow and ring of light betrays it
SINGULARITY
The singularity at the centre of a black hole, infinite density at a mathematical point
🔮 At the center: infinite density, zero volume
📏 Mass of a mountain compressed to zero size
⚛️ Spacetime curvature becomes infinite at the singularity
