Phenomenon Of Amplified Echo Inside Circle
The sonic effects from the circle can be heard if someone steps inside the circle and echo from any noise will reflect louder, but it will distort outside or across the circle.
There are many unexplained theories of acoustic anomaly of Center of The Universe. Many beliefs also say that it was made by a vortex, where all the cosmic energies meet at one point.
Most likely, the sound effects caused by the structures of wider planters and benches located less than 10 feet from the center, which bounces back and reflects the noises as the waves, create the effects as well.
The amplifying experience is actually wasn’t planned at the very beginning, since it was the original location of bridge and pedestrian in downtown Tulsa.
Despite the concrete circle mark and powerful echo effects, Center of The Universe is surrounded by many historical buildings in town.

The History Of Center of The Universe
In 1980, there was a big fire that burned down the Tulsa Arts District and headed south along South Boston Avenue and caused major damaged to the bridge.
After the damage, the bridge has rebuilt and reconstructed into a pedestrian walkway.
In 1983, John Laur is the architecture who contributed and made the circle design on the floor of the bridge in downtown. He made the 2.5 meter small circle pattern on the bridge that is now famous as The Center of Universe.
