Protect Ourselves from an Exploding Star

LNM Radio Network

Eventually, stars die — not with a whimper, but with a bang.

When they do, there’s the potential that any nearby planets could be devastated by destructive cosmic rays, potentially wiping out life on those worlds.

We’re not quite ready to build any sort of defense for human civilization against a barrage of this sort, but scientist of the Astronomical Observatory of Belgrade,
theorize that in a time span ranging from a few decades to a hundred years away, we might be able to construct the sort of barrier that could withstand a blast of electromagnetic or cosmic-ray radiation that would be caused by a supernova or gamma ray burst from the end of other sorts of star (though predicting these explosions and their trajectories may be more complex than building that barrier).
