Comets may have destroyed life's ingredients instead of delivering them to Earth
The Brief
- New University of Cambridge research challenges the century-old theory that comets delivered life's building blocks to Earth.
- The study suggests comets traveled too fast and struck at unfavorable angles for fragile molecules needed for life to survive.
- Under these conditions, the molecules may have been destroyed rather than delivered intact.
Why it matters
If comet impacts destroyed rather than delivered prebiotic molecules, a major explanation for the origin of life on Earth would need revision, affecting how scientists search for life's origins elsewhere.
Who’s affected
- astrobiologists and origin-of-life researchers
- planetary scientists studying comets and impacts
