Solar Flares and Their Impact

The video discusses the potential impact of solar flares on Earth, drawing parallels with a historical event 150 years ago when a solar flare disrupted telegraph systems. It explains solar flares and coronal mass ejections, highlighting their potential to cause geomagnetic storms that could severely damage modern electrical infrastructure. The societal consequences of such an event could be catastrophic, affecting agriculture, emergency services, and leading to widespread chaos. The video also compares this potential disaster to the asteroid impact that wiped out the dinosaurs.
