The world’s most prestigious science journal just published an ex-astronomer’s remarkable screed.
Scientists are still discovering how many systems, controls, and other aspects of planetary fine-tuning are in place to ensure that we have abundant life.
“The atmosphere lets through just the light we need,” says Denton, “and the sun puts out just the light we need. It’s a remarkable coincidence.”
At the end of a perfect day, when the Sun is setting, the beams of light we see slant through the atmosphere nearly parallel (tangent) to the Earth’s surface.
It’s no help having essential elements in the Earth’s crust if they can’t get to the organisms that need them.
