5. The Taos Hum
The Taos Hum, commonly known as “The Hum” is a phenomena involving widespread reports of a persistent and invasive, low-frequency humming, rumbling, or droning noise. An interesting fact pertaining low frequency noise that is associated with humming, is that at least two 2-percent of people could hear it; each hearer at a different frequency between 32 Hz and 80 Hz, modulated from 0.5 to 2 Hz. Some people, apparently, have been able to hear the hum, or hear it more clearly, when inside buildings as compared with being completely outdoors.
Widespread skepticism has been voiced about the Hum’s existence from people who cannot hear it. In 2009, the head of audiology at Addenbrooke’s Hospital in Cambridge, David Baguley, said he believed people’s inability to hear the hum caused by the physical world about one-third of the time, and stemmed from people focusing too keenly on innocuous background sounds the other two-thirds of the time. Although there are not many adherents of his theory, a conclusive reason for The Hum continues to elude us.(source)
4. Ball Lightning
Ball lightning is a one-of-a-kind natural phenomenon that involves luminous, spherical objects which are associated with thunderstorms, but which last longer than the split-second view of a lightning bolt. Ball lightning has been observed across India, Western Australia, Sweden, United Kingdom and other parts of the world. Some reports even suggest that the ball had exploded inflicting significant casualties on people and objects in its vicinity.
It has been suggested that ball lightening might be the source of legends that describe luminous balls, such as written about in Mapuche Anchimayen mythology.
Many scientific hypotheses have been proposed over the years to explain this bizarre natural phenomenon, but none of them have gained wide enough acceptance to readily accept their authenticity.(source)
3. Oh-My-God Particle
On October 15, 1991, University of Utah’s Fly’s Eye Cosmic Ray Detector detected an ultrahigh-energy cosmic ray. The observation came as a shocker to astrophysicists who estimated its energy to be approximately 3×10 ^20 eV, or about 20 million times more energetic than the highest energy emitted in radiation by previoulsy observed intergalactic object.
The kinetic energy of the particle was such that it was travelling at 99.99999999999999999999951% the speed of light. Astrophysicists were so left in awe that they named the particle the “Oh-My-God Particle”.
Ever since the particle was first observed, at least fifteen similar events have been recorded to confirm the phenomenon; all, however, without any explanation or even a hypothesis attempting to explain its occurrence.(source)
2. Morning Glory Cloud
Morning Glory Cloud is a rare atmospheric phenomenon. It is a type of tempestuous, Arcus cloud that can stretch up to 1,000 kilometers in length. It is about 1 to 2 kilometers in height and forms an unbroken cloud line, most always accompanied by violent winds. These have more commonly been observed in Northern Australia, near the Gulf of Carpentaria region.
Due to its extremely unpredictable nature, no scientific explanation has found suitable explanation, so these clouds continue to bewilder us.(source)
1. Hessdalen Lights
Hessdalen lights are beams of radiant white, yellow and red lights, that can be stationary or free-floating, and appear 10-20 times every year in Norway’s Hessdalen valley. These lights gained special attention due to their increased frequency of appearance between 1981 and 1984.
Years of scientific research started by UFO Norge and UFO Sweden in collaboration with multiple Norwegian institutions, have failed to explain the reason or reasons behind the reoccurring and spectacular displays of the Hessdalen lights.(source)
