#cosmic_center a small circle located in the state of Oklahoma, USA, with a diameter of about 30 inches, and it is called the "center of the universe"....
The strange thing about this circle is that if you stand in the center of it and make any sound, the sound will bounce back to you several times higher than the sound you were making...
The strangest thing is that whoever stands outside the circle will not hear you, no matter how loud your voice is.
There is no clear scientific reason for this phenomenon so far!?
