Barry Evans' column ("Science. It Works Etc.," Aug. 24) should have mentioned that Planck's beautiful curve represents the origin of Quantum Mechanics.
That it precisely fits the Cosmic Microwave Background proves that Quantum Mechanics works exactly across all expansive space and time, originating in the Big Bang 13.8 billion years ago. Of course, science does not explain everything. The Big Bang's origin remains a mystery.
