The actual shape of a black hole depends on how you’re looking at it:

---

🔵 1. Non-Rotating Black Hole (Schwarzschild Black Hole)

• Shape: Perfectly spherical.
• It’s a symmetric sphere of space where gravity pulls equally in all directions.
• Nothing can escape beyond the event horizon — a spherical boundary.

---

🌀 2. Rotating Black Hole (Kerr Black Hole)

• Shape: Flattened sphere or oblate spheroid.
• Due to its spin, the black hole bulges slightly at the equator (like Earth).
• It also has:
  • A flattened event horizon.
  • An ergosphere — a region outside the event horizon where space is dragged by rotation.

👁️‍🗨️ What We See (Shadow of a Black Hole)

• When astronomers image a black hole (like in the famous M87 black hole photo), they don’t see the black hole itself, but its shadow.
• The shape of that shadow is circular, even for spinning black holes — due to how light bends around it.

• The dark shadow is nearly circular.
• Surrounded by a glowing ring of hot plasma falling into the black hole.
• This supports general relativity’s prediction of a roughly spherical or slightly oblate shape.
