     Comets probably didn’t deliver life’s building blocks to Earth

     Most comets would have hit Earth with too much speed and at too sharp an angle for life-giving molecules to survive impact, a new study suggests.

     ¿Y si los cometas no sembraron la vida en la Tierra?

     Después de todo, los cometas podrían no haber sido los responsables de 'sembrar' la vida en nuestro mundo. Lo cual supone un serio revés para una idea que lleva más de un siglo seduciendo a los científicos: que estas antiquísimas rocas de hielo trajeron hasta aquí los componentes moleculares primordiales para que la vida pudiera surgir. De hecho, se sabe a ciencia cierta que los cometas transportan en su interior muchas de estas preciadas moléculas.La nueva investigación, sin embargo, recién...

     100.000 simulacija otkrilo koliko je vjerojatno da su kometi donijeli život na Zemlju

     NOVE simulacije pokazuju da je teorija o postanku života iz tvari koje su donijeli kometi vrlo malo vjerojatna. Šanse za uspješnu isporuku ključnih molekula na Zemlju su iznimno male.

     Did comets really start life on Earth? New study challenges long-held theory

     Researchers from the University of Cambridge conducted computer simulations to examine the role of comets in life's origins. The study found that high-speed impacts likely destroyed important chemicals, such as hydrogen cyanide. Only a small percentage of simulations indicated successful delivery of these compounds by comets. Additionally, most impacts during early Earth history could not deliver intact organic molecules.

     Simulacije pokazale: Panspermija na Zemlji je moguća, ali i vrlo malo vjerojatna

     Teorija o nastanku života putem udara kometa znatno manje vjerojatna nego što smo dosad možda pretpostavljali, barem kad je riječ o našem matičnom planetu
