What is the greatest mystery of all time?

The Taos Hum

In the small town of Taos, New Mexico, there is a certain buzz often heard on the horizon that can be compared to the sound of a distant diesel engine. Although it can be heard by the naked ear, various sound detection devices are not able to pick it up. This is known as the Taos Hum and up to this day, no one still knows how this sound is being created.

The Lost City of Atlantis

The lost city's of Atlantis (https://www.ancient.eu/atlantis/ ) is one of the oldest and greatest mysteries of the world. Since ancient times, people have been trying to locate Atlantis, which is believed to have submerged after an earthquake or tsunami.

Greek philosopher Plato described Atlantis as a large island located near the Rock of Gibraltar, home of the most advanced civilization and being of unrivaled refinement with a glorious palace. Among its other traits, Atlantis was filled with beautiful citizens, a Poseidon temple and concentric walls and canals.

To date, nobody has been able to find the city – underwater or otherwise – though this hasn’t discouraged numerous theories about its possible location. Countless historians and explorers have attempted expeditions to find the underwater island, but whether in South America (as recently reported), off the Greek Islands, or near Antarctica, Atlantis has remained elusive and one of the greatest mysteries of human history.

Lal Bahadur Shastri

He died an unexplainable death since he left the country healthy. Many have claimed that he died of heart attack, but the doctors and other specialists who have checked him out, including his wife, confirmed that he was A-okay. His wife had also made the assertion that the Tashkent Pact, upon signature, gave the chance for him to be poisoned. This was never proven since there was no post-mortem diagnosis of the body so every assumption that could be answered were already included in the grave.

CROP CIRCLES EXPLAINED.

The most compelling aspect of crop circles is their complexity and the speed at which they appear. But they lost this appeal overnight when, in 1991, two men from Southampton, England, admitted they had been creating hoax crop circles for 15 years.
The pair were able to make intricate patterns using planks, rope, hats and wire - and could create a 40-foot circle in 15 minutes. The only reason they came clean was because one of the men was running up considerable mileage on his car and had to convince his wife he wasn't having an affair. He still publicly demonstrates the art today.
