Orbs are spherical objects that are often seen in photographs, particularly in areas with low light or flash photography. They are typically thought to be caused by dust, moisture, or other particles reflecting light, creating a circular shape. Some people believe that orbs may represent spiritual entities or energy, but scientific explanations attribute their appearance to environmental factors. In the context of paranormal investigations, orbs are frequently associated with ghosts or spirits. Investigators often use infrared cameras and other equipment to capture these phenomena. While some enthusiasts claim orbs are evidence of the supernatural, skeptics argue that they are merely optical illusions or artifacts of photography.
