There is no sense in giving into the pointless fearmongering about phenomena such as this that is started by uneducated individuals.
No, the world isn't going to end. I guarantee that I will be on PC on Aug 22nd reading this thread with a smile on my face.
People who make such baseless claims that can't even be backed up by actual scientific evidence about how the world is coming to an end over eclipses or whatever else are idiots.
The 2012 crap comes to mind because of how people thought that the world was going to come to an end on Dec 21st 2012, yet look where we are now lol.
I am going to enjoy it personally. I love the night.
