Hello all, just thought I'd post this link to a story about these 'strangelets'. Have a read, it's very interesting. Here's a little snippet of the article:

They are only the size of a pollen grain but so dense they can rip through the planet and exit on the other side in seconds.

If anyone has any good info on this, apart from searches on www.google.com - cos I already have done that - post em up, I find it very, very interesting and would like to read more on this kind of stuff.

Cheers,
Greg
