Basically two Russian scientists performed experiments near the north pole using the Kozyrev mirror, which is a device made from long sheets of aluminum curled into a cylindrical spiral. It is alleged to focus different types of radiation, including that coming from biological objects and when those objects are placed inside of it they begin to interact with space time.
Because of the construction of the mirror and how it reflects light, and because of the correlation of light & the flow of time, this mirror allows the user to receive messages from other points in time and other dimensions.
It seems like this cylinder mirror shape is like mirror skrying on steroids.
It is not quite clear though why they havent used reflective glass or actual mirrors as they still continue to use reflective aluminum to this day.
*Extra info: the researchers did say that the location did play a viable factor since the experiments were conducted above 73 degrees latitude, where apparently supernatural phenomenon is more prevalent.
