Space is vast, yet space is not empty. Anything could happen. Nice application of particle simulations. Direct link to PDF if anyone else wants it. Has transfer probabilities based on their sim, which runs over a 30 kyr milieu. It's probably guessing a bit low if we want to know "ever." http://arxiv.org/PS_cache/arxiv/pdf/1108/1108.3375v1.pdf http://arxiv.org/PS_cache/arxiv/pdf/1108/1108.3375v1.pdf
