Aluminum foil? Look towards the moon tonight. Some of the impacts are so large, they can be seen from here on earth, with the unaided eye, at a distance of 240,000 miles away.
The only thing tin foil here are those that think earth being struck by a large astroid, is some kink of wacko idea. It's not. It's already happened, and will happen again.
From the initial post:
"has someone in some1 observatory found something1 even nastier coming? And they2 won't tell 3 us4, becuase5 they2'd fear we4'd panic."
2 The infamous "they".
3 "They", "them", etc.. are keeping important information from "us".
4 Whatever wackjob theory involving "them" isn't important just to the wackjob but all of "us", "we", etc..
5 "We" don't have time to spell-check! "They" are after "us".
