Mystery about ghosts in the gym

When Kim Peterson arrived at the sports club on the morning of September 25 and watched the video taken from the security camera, she was taken aback when she saw a faintly light-like mass of light hovering around the exercise machines.

Kim is the owner of Anytime Fitness, a sports club in Overland Park, Kansas, USA. The video was recorded at 2:21 am, about half an hour after the last person left the club. " Ghosts " appear about 9 times in 2 hours and every time it moves around the gym. This means that the motion detection system has been activated 9 times.

All were confused, from Kim, her staff, the club's members to the company providing security cameras. Kim said, so far, security cameras have only been activated when there is movement inside the room.

" I called the security company and they didn't understand why the light could activate the camera. They claimed dust and insects, the light from the street car couldn't make the camera turn on automatically, " she said.

Immediately, the story of ghosts in the gym became the hot topic of the media. Many people hypothesize about the origin of the specter: a prank, a bug, a light from a car passing by the club. However, most people believe that a ghost has visited the gym. Kim's son also speculated that it was his grandfather's soul.

Many experts have explained this mysterious phenomenon from a scientific perspective. The following are the most remarkable arguments.

Argument 1 : The origin of the light block is an object that is white and unclear. "Fisheye" security cameras used by Kim's club are designed to record activities above the ground and 6 meters or more from the camera's location. Things that are in that distance will be clear, and objects near the lens will become blurry. From that, it can be said that strange objects are very close to the camera.

Argument 2 : The strange object does not glow on its own, but only reflects white light from somewhere near the camera. Reflective light activates the camera.

Argument 3 : Although Kim and reporters claim ghosts wandering near the machines, image analysts find it jumping or walking through them. Its movements indicate that it does not interact with objects in the room. Since then experts believe it hovered inside the gym.

Argument 4 : The studio has at least 8 cameras activated on the evening of September 24, but "ma" only appears in the footage of one. If the light block actually appears in the room, all 8 cameras must record its image, of course at different angles. But that does not happen. Therefore, it can be concluded that this mysterious phenomenon, whatever it is, only happens with a camera.

The most plausible explanation is given on October 14: ghosts are a small animal . A spider, a fly or a bug has clung to the camera lens. That's why its image is blurry, only appearing in a camera's film and doesn't interact with everything in the room. The fact that a moving light cannot activate the camera system is because they only detect movement, not light. Therefore, the movement of the bug triggered the camera's sensor.
