Study Suggests 'Microlightning' in Water Droplets May Have Sparked Life on Earth
Stanford researchers propose that tiny electrical discharges in water sprays created organic molecules essential for life, offering a new perspective on Earth's origins.
- The study shows that 'microlightning' in water droplets can produce organic molecules like uracil, glycine, and hydrogen cyanide, key components for life.
- Researchers recreated early Earth conditions by spraying water into a gas mixture of nitrogen, methane, carbon dioxide, and ammonia.
- This mechanism challenges the Miller-Urey hypothesis by suggesting that frequent water sprays, rather than rare lightning strikes, could have jump-started life.
- Microlightning occurs when oppositely charged water droplets collide, producing tiny sparks capable of driving chemical reactions.
- The findings provide a new angle for understanding prebiotic chemistry and the potential origins of life on Earth.
