sounds pretty dangerous travelling at high speeds

True. But I have to think that if a civilization had figured out a means to achieve travel between star systems, they'd have the means to navigate through something like the Oort Cloud.

True. So I was thinking the OC might serve as a type of filter to keep the trashier, low end ET's away. It seems like a fairly substantial obstacle that would take a while to get thru (if it's 3 light years out).

If alien species were to travel here, they would have to be at least a Type II civilization meaning that they are capable of harnessing the energy of their host star.

Humans aren't yet a Type I civilization. A Type I civilization is capable of fully harnessing the full energy and resources of their planet.

If an alien species is capable of harnessing the full energy of their host star, then they sure as hell are capable of safely passing thru the Oort Cloud or completely bypassing it. A Type II civilization will be hundreds of thousands to several million years more advanced than a Type I civilization.

A Type II civilization would laugh at the Oort Cloud. Or perhaps the Oort Cloud would be as insignificant to the alien species as a sunny morning breeze is to a human.
