WHY is the center of the universe is in Tulsa? Tulsa is a small city in Oklahoma,
a unique acoustic place. "The Center of the Universe" is a 75 cm diameter circle of concrete. It is followed by the next circle of 13 bricks and circular brickwork. The whole area extends to
about 2.5 m in diameter. If you stand in the center of this place, any
sound you make will be amplified many times over, and the person standing outside the circle will hear
your voice distorted and indistinct.
