Investigadores de Cambridge consideran improbable la entrega de vida por cometas

Investigadores de la Universidad de Cambridge afirmaron que sus últimos modelos computacionales indican que el intenso calor y presión de los impactos de cometas a alta velocidad destruyen las moléculas orgánicas clave, lo que hace altamente improbable que los cometas hayan entregado los bloques constructores de la vida a la Tierra temprana. Anteriormente, el mismo equipo había señalado que compuestos prebióticos como el cianuro de hidrógeno tendrían muy pocas probabilidades de sobrevivir a la colisión, basándose en simulaciones de 100 000 impactos que mostraron una entrega extremadamente rara y que Marte podría haber ofrecido condiciones más favorables. Estos hallazgos refuerzan estudios computacionales previos que cuestionan la hipótesis de que los cometas aportaron los precursores orgánicos de la vida.

Computer models of 100,000 comet impacts indicate that delivering enough hydrogen cyanide to support the origin of life on Earth would have been highly unlikely, while Mars may have been more favorable for such deliveries.

Computer simulations suggest that comet collisions would have vaporized most hydrogen cyanide, making comets an improbable source of pre-biotic molecules, with asteroids or terrestrial synthesis favored instead.
