Hessdalen Phenomenon Lights
Hessdalen is a valley in Norway, where there live no more than 200 people. In this valley, many years, a phenomenon manifested itself, which until this time did not have an explanation. The sky is seen, actually, with a certain frequency ,a strange lights, which take different forms (although the most common is the globe), sizes and colors. The lights can be fixed or intermittent, or moving buildings, fixed air, the mountains or on the ground. Their duration can be from several seconds to several minutes. The reality of this phenomenon is attested by eyewitnesses, but also by the photographs taken, coated or analysis of radio waves.
For over the years have given different explanations, but most are finding that it comes to aliens. Scientists who went to Hessdalen and have studied the phenomenon say that there may be physical manifestations plasma or piezoelectric. Piezoelectricitatea is the property of certain materials present in the soil (especially crystals), generate a potential difference, if they are subjected to mechanical forces: compression, stretching or breaking. This can cause the lights, or may be concentrations of power, which produces light at certain times. But do not exclude correlation with sun activity (spots and solar wind) in the presence of radon gas present in low atmosphere. Many assumptions that make this mystery to be elucidated.
