Life from Chicxulub

20 November 2013

At https://medium.com/the-physics-arxiv-blog/56e227224a25 … rocks from the Chicxulub asteroid 'must' have spread through the solar system, it is theorised in the arXiv paper. What do they mean? It seems the life in Earth rocks could have been carried anywhere in the solar system – to Mars or Venus, Jupiter or Saturn, or to their moons such as Callisto and Titan etc. It has been calculated some 70 billion kilograms of rock and debris could have been blasted off the surface of the Earth by the asteroid collision. Hence, we have the possibility of space rocks hitting Earth and spreading the seeds of life, but also, earth rocks doing the same thing elsewhere. Neat.
