Tulsa, Oklahoma: Sonic Center of the Universe

The Sonic Center of the Universe is even better if visiting after last call. You will be surprised to find that you won't be alone. The friendly locals will greet you and give you in-depth insights into this echoing portal of mystery. Banging on the knocker of the intergalactic antenna is even more satisfying after dark.

Don't worry - it is in the business district and hotels nearby give out much needed ear plugs (one pair per room).

My wife and I always try to visit roadside sites -- this was a good one. So strange; as soon as you stand at the center you can hear the echo.

On a side note: the big metal tower has two big knockers on it. A person from Tulsa said to knock the knockers and make a wish and it will come true. I will let you know if it works when I hit the lottery.

I just visited the center of the universe and was totally blown away!! I grew up in Tulsa in the 70's and never knew it was there. Stood on the "RAIL" and quietly said "hello" and was blown back by the "HELLO-O-O!" that answered! Gosh, I wonder if they speak our language? And what is it they want to tell us....

I live in Tulsa and I have been to the Center of the Universe many times. I keep going back there for several reasons and 1 happens to be because it is really astonishing and somewhat eerie... Another reason is to figure out how it does what it does, which is create an eerie echo that only you, the speaker, can hear.

I have came to a conclusion that it IS in fact the planters. If you face North and walk down the longer portion of the bridge opposite the huge tower (BOK Tower) to the last half circle, cut out, that also has a circle in it, and half of a planter around it, if you stand in the center of the circle and talk directly toward the planter you will hear a much stronger echo in that space than you do at the "Center" itself. The echo can be heard in the Center and at the last half planter, the others do have an echo but you can barely hear it though. So I've kinda debunked that phenomenon...I think.

Visited this place while in town for the holidays. Very neat. I could hear my echo, but no one else could. Very interesting and made us laugh a little bit. Well worth the trip to see it. No traffic on Sunday and easy parking.
