B An Ancient Solar Storm 9200 years ago is Cause for Concern

AI Thread Summary
An ancient solar storm approximately 9,200 years ago raises concerns about the potential impact of similar events today. A recent discussion highlights the risks of a Carrington-type solar storm, which could be catastrophic in our technology-dependent society. The 2012 solar storm incident serves as a reminder of how close we came to experiencing such an event. Additionally, the conversation touches on the possibility of other catastrophic events occurring without leaving a trace. The discussion emphasizes the need for awareness and preparedness for solar storms and other natural disasters.

I think that even a simple repetition of the Carrington event will be disastrous. We do not have to look at an event 9,000 years ago. 160 years are sufficient.
 
A Carrington type event nearly missed us in 2012:

And yes, this kind solar storm hitting the Earth in this technological age would be catastrophic.
 
It seems every kind of event where the Earth survives shows a scar of some sort that scientists can discover. Only a catastropic event of a similar type occurring over another might destroy any prior evidence but we would never know because there’s no evidence to know.

Theres an interesting book on catastropic events called The Doomsday Book where several different types of events are described and their aftereffects are explained in greater detail.

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
