"Hey, check out what NASA is publishing! Really scary! Starting November 15, there will be complete darkness on Earth for two weeks!" - This is the message recently making the rounds on social media, often accompanied by a "reminder" that something similar is mentioned in the Zohar.
A quick check reveals that no such announcement was ever made by NASA. The space agency does not predict any days of darkness; this story is completely fabricated. It seems that someone is taking advantage of the current tense situation to make jokes and/or scare people. It's advisable to treat such "news" accordingly and not believe everything - especially not to forward unverified information.
