Around nine years ago now I noticed that when I look at somebody or another living being they react to it. The responses can include; a blink, raised eyebrows, a flinch, look up, look in my direction, or just a general change in trajectory. This phenomenon is known as a gaze response, and the most prominent researcher that I have come across studying it is Rupert Sheldrake. It is not understood how it happens as there is no physical medium or connection in between people as to how it could happen and so it is a non-local phenomenon (locality means that something can only effect something in direct contact/ immediate proximity with it). However, around seven years ago I noticed that the same responses were also occurring when I watch somebody in a video that was filmed in the past which raised a lot of questions that are discussed in the book I wrote called Change the past in the future - a look into the existence of time by Henry Norsworthy.
Feel free to leave a comment about any experience you have with gaze response.
