The “Center of the Universe” is a little-known mysterious acoustic phenomenon. If you stand in the middle of the circle and make a noise, the sound is echoed back several times louder than it was made. Even more strange, no one standing outside of the circle can hear a thing. It’s your own private amplified echo chamber.
Located in the heart of the downtown Tulsa, the ‘centre of the universe’ is nothing but a small circle of about 30 inches in diameter made of worn out concrete. This is in turn surrounded by one more circle which is made up of 13 bricks and so on. Altogether it adds up to 8 feet in diameter.
