10 Times the World Almost Ended Image source: Extreme Tech

On 23rd July 2012, a huge solar storm occurred on the surface of the sun, which ejected a large number of coronal masses. The coronal mass ejection was as powerful as that of the Carrington Effect and was speeding towards Earth. Luckily, the Earth missed the ejection by a mere nine days. Had it struck our world, every electronic device would have been toast. Scientists estimate that the damage would have cost more than 2 trillion dollars, and it would have taken decades to recover from the damage.
