Really dumb (probably) questions about plagues and research

[Puke]

i think some of the facilities in the organic tech tree prevent low levels of plagues, but the only way to cure them is with ship components.

if you are that well developed, dont forget about building ringworlds or sphereworlds. the ultimate coup-de-grace and sign of imperial might!

and, incidentially, the only way to make sure a sun does not accidentily go nova.
