It is so incredibly cool that solar flares can leave a radioactive signature in tree rings. Like that sounds like it should be fake - corroborating it with written accounts must've been such a mind blowing process.
This also reminds me of the national parks up in NorCal that have cross sections of tree trunks that show which rings of the tree correspond with significant historical events. It's great perspective to see that a tree was halfway through it's life when the magna carta was written.
It would be good if similar research was performed on/for other ancient civilizations to better understand our sun.
A big Coronal Mass Ejection (CME) is going to cause a lethal geomagnetic storm, it’s not a matter of “if” but of “when”. Our modern lifestyle is heavily dependent on electronics and we’re going to be heavily impacted :-(
I've been talking to a friend about this lately, in the context of "prepping". Curious if anyone here knows whether a laptop computer could potentially get fried from a solar storm if it were unplugged? I'm guessing it's just things connected via wires that would be destroyed. If I'm mistaken, would a faraday cage keep the laptop safe?
A faraday cage with the right hole size, or a faraday shield of sufficient thickness, should protect it against very intense effects, up to EMPs.
Just being disconnected already helps, it comes down to strength of the solar flare vs length of metal piece.
I know some military hardware is built with a metal box with holes on the inside of the plastic case -- a faraday cage -- though that probably also serves to minimize RF leaks.
