A genus of non-photosynthetic algae.

If we ever found and wanted to colonize a near-Earthlike world with a native biosphere the undertaking would seem to be highly hazardous since we don't even understand how some of our native pathogens work.

IMO, the biggest fantasy in Star Wars is that everyone wouldn’t have died long before from galaxy spanning plagues - over and over again.

This has me thinking, there must be some intersection point, where a civilization can't grow any larger while staying connected because it'd create new diseases faster than the medicine of the time could develop cures/treatments/vaccines.

Probably directly related to ease/speed of travel and how controllable it would be too. In Star Wars, random joes seem capable of rapid and uncontrolled movement between arbitrary star systems with little to no possible border control, which would make it really easy to spread everything, and impossible to stop. Even planetary blockades seem ineffective.
