We need to get on that magnetar defense.

Let's build a Faraday cage for the Solar System! Now, on a more serious tone, we may want some contingency plans with underground environments and something to preserve some life for long enough we could be able to re-seed a biosphere on the surface. Useful for ice ages too. Now imagine it as the start of a story - we terraform Mars, or Venus, only to trigger a re-seeding of the now friendly environment by long buried machines left by a dead civilization.

  Who says we haven't been making our way out for awhile now? I also like the theory that a previous civilization was all soft biology based and that its tech would leave no trace. Speaking of underground environments, Mercury would be an excellent location. http://www.einstein-schrodinger.com/mercury_colony.html http://www.einstein-schrodinger.com/mercury_colony.html

    An initial colony could be supplied by advancing multiple launches with supplies and landers before the first colonists arrive at sunset. They’ll have 88 days to assemble the underground habitats or abort and come back. Are there any perpetually shaded areas? If so, the 88 day deadline could be extended by as much as we want just by sending supplies in advance. And having between 4 and 10 times as much sunshine we could even generate some power from the light reflected in the crater/canyon rim.

      Yes, there are craters with water ice in them that are permanently shaded near the poles. Solar concentrators could be moved out of the shadows and redirect light, generate electricity or heat. I think we could be less than 5 years away from landing a Starship in a crater on Mercury.

  The Faraday cage that can block gamma and cosmic rays masses more than the solar system. Probably you find a pair of rogue gas giants, and set them orbiting one another out in interstellar space, arranged so one is always positioned lbetween your planet and the nearest magnetar.

  It would be quite easy at the bottom of some of our deeper mineshafts. The radioactivity would never penetrate a mine some thousands of feet deep. And in a matter of weeks, sufficient improvements in dwelling space could easily be provided. A computer could be set and programmed to accept factors from youth, health, sexual fertility, intelligence, and a cross section of necessary skills. Of course it would be absolutely vital that our top government and military men be included to foster and impart the required principles of leadership and tradition. Naturally, they would breed prodigiously, eh? There would be much time, and little to do. But, ah, with the proper breeding techniques, and a ratio of say, ten females to each male, I would guess that they could then work their way back to the present gross national product within say, twenty years.

    I see what you did there.
