Do You Still Belive that The Great Wall of China Can be Seen with Naked Eyes on the Moon ?
Do you still believe the saying "The Great Wall of China is only construction that can be seen with naked eyes on the moon" ? If you do, you should lament that you've been being deceived for a long time.
The distance between the earth and the moon is 384,400 kilometers. If we watch the earth on the moon, the earth is just 3.7 times bigger globe than the moon which we can see on the earth. According to the writing by astronaut named Alen Bean, "The earth is just beautiful sphere which is almost white (clouds), some parts are blue (sea), there are yellow masses sporadically (deserts), and some places are green (mountains)", "Noone can see any artificial construction with the unaided eyes on the moon" he added.
Computing scientifically, a man who has a best eyesight can only discern black-line of over than 700 points on the white background in this distance. But the width of the Great Wall is from 4 to 12 points at most.
In fact, The Great Wall cannot be seen when we are futher than a couple of thousands kilometers from the earth. In the altitude that The Great Wall can be seen, we can see other constructions such as high-ways, rails, cannals.
If so, where did that saying come from ?, the parties concerned with NASA have been annoyed by questions like this when they met anyones. They guess exaggeration of some early astronauts may be misrepresented.
Accoding to another report, Chinese school textbook says, "The Great Wall of China can be seen on the spacecraft." so most Chinese people believe this and think The Great Wall is great as much as it, then their ancestor was great also. However, when after an orbital flight of their very first manned spacecraft, Chines media asked their first astronaut, "Yanri-Wei" whether he could have seen the Great Wall, but he answered he couldn't. As soon as his interview had been released, Chinese netizens got so depressed. That was the time to shrink their swellen pride.
No whoever someone else, since Chinese astronaut confessed that he could not see the Great Wall, their old belief which the Great Wall can be seen on the moon was revealed as a fabrication. Therefore, Chinese goverment made a decison to revise their textbook. it's a very exceptional case. it seems to come from the concept that they cannot make people be inspired by wrong information.
These pictures below show the earth which can be seen on the moon, Far from the Great Wall, anything doesn't seem to be seen with naked eyes.
You Can See as much as You Know !!

Killer Whales' Hunting for Gray Whales
This post is extracted from masterpiece natural documentary TV show, "Blue Planet" on BBC. A few years ago, I was addicted natural documentary for a couple of days, I think this was the best scene I had seen at that times.
This shows killer whale's hunting habit very well. (Movie clip contains Korean subtitles, because it was supposed to be posted on my Korean blog)
What a poor gray whale mother and her cub ~ :(
