Kerala's Red Rain: Spores or Space Panspermia?
From July to September 2001, heavy, color-changing rain fell across Kerala, with about 9 million red particles per milliliter and an estimated total mass of 50,000 kilograms. Scientists attributed the phenomenon to airborne spores of the bright-orange alga Trentepohlia, which coated trees and lamp posts. However, two Mahatma Gandhi University physicists suggested a meteor deposited extraterrestrial biological cells and proposed panspermia, a claim that has never been validated in peer-reviewed research.
