How the Penrose process extracts energy from a spinning black hole

A spinning black hole can give away some of its energy

A spinning black hole twists the space around it. In a region just outside the black hole, an object can enter and then escape with more energy than it had before. That extra energy comes from the black hole’s spin.

Adaptive optics can sharpen telescope images

Earth’s atmosphere blurs images taken by telescopes. Adaptive optics measures and corrects this distortion, letting telescopes produce images much closer to the sharpness their size should allow.

The microbes in your body carry far more genes than you do

≈100× as many genes

The human body contains roughly as many bacterial cells as human cells. But those bacteria together carry an estimated two million genes, around 100 times the number of human genes. Their combined set of genes is therefore far larger than ours.
