A large coronal mass ejection could send this planet into the medieval ages extremely fast...Stars are bizarre, extremely dangerous, beautiful and almost supernatural in size and power. Even their existence nearly beyond comprehension.

This would consist of what, helium? Is there some way of telling if such a blast has been in earth’s past?

I disagree. Usually we get about 2 days warning that a CME is on the way. We should be able to stockpile food and fuel and shut down the electrical grid for the day that it hits. Everything would have to be off and it should survive as long as it is not connected to ground.

This should be no big deal. I am not an EE, but I do have a masters in physics and I also stayed at a Holiday inn last night.

Existence itself is beyond comprehension, as far as that goes.

To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
