The “I before E, except after C” rule does not always apply
In fact, there are so many occasions where it doesn’t apply that even following the rule may seem stupid when you stop to consider it. The rule, recited to elementary school children, functions in words like friend, believe, and receive — but in many, many other situations, it doesn’t. In reality, statistics suggest that the rule is incorrect 75 % of the time— words like weird, glacier, and science break the rule outright.
The Great Wall of China is not the only manmade structure visible from space
This is false on multiple counts. For one thing, in 2003, the Chinese astronaut Yang Liwei went up into space and then said that he could not see the Great Wall. Other space explorers have suggested that you can see it, but only in certain circumstances, such as when there’s snow on it to make it stand out more from the surrounding land. Additionally, you can see plenty of other manmade structures from space, including the pyramids and even some roadways and bridges.
