Because black holes bend light violently around them, you can see multiple distorted copies of the entire surrounding galaxy curved around the silhouette, like looking into a cosmic hall of mirrors. 🪞
Roger Penrose proved that an advanced civilization could drop matter into a rotating black hole's ergosphere and extract up to 29% of its mass-energy, making it the ultimate cosmic battery. 🔋
Rotating black holes drag the very fabric of space-time around them like honey stirred by a spoon. Inside this region, called the ergosphere, it is physically impossible to stand still. 🌪️
