An estimated 3,700 years ago in the Middle East exploded a meteor or comet, destroying human life on the surface of the earth, called the Middle Ghor, north of the Dead Sea, say archaeologists who have found evidence of cosmic air flow.
Airburst "was immediately devastated by about 500 km2 [about 200 square miles] just to the north of the Dead Sea, not only destroying 100 percent of [cities] and cities, but also destroying soils from already fertile fields and covering the east of Ghor with the excessively heated salt water of the Dead Sea Anhydride, which extends through the landscape with the frontal shock waves of the event, "the researchers wrote abstractly paper presented at the annual American School of Oriental Studies meeting in Denver from 14 to 17 November. Anhydride salts are a mixture of salt and sulphate.
"Based on archaeological data, it required at least 600 years to sufficiently recover from the destruction of soil and contamination before civilization could again be created in the east of the Middle East," wrote. The destroyed sites were Tall El-Hammam, an ancient city that occupied 89 acres (36 hectares) of land. [Wipe Out: History’s Most Mysterious Extinctions]
Among the evidence that scientists have discovered about the flow of air, there are 3700-year-olds of Tall El-Hammam ceramic pieces that have an unusual look. The ceramic surface was glassy (turned to glass). The temperature was so high that the zirconia pieces turned into gas during a pot – something that had a temperature of more than 7230 degrees Fahrenheit (4,000 degrees Celsius), said Phillip Silvia, a field archeologist and supervisor with the Tall El Hamm Excavation Project. However, the heat, while vigorous, did not last long enough to burn through healthy pieces of ceramics, leaving the ceramic part below the surface relatively uncompetitive.
Silvia said that the only natural event that could lead to such an unusual destruction model is the cosmic air blow – something that occasionally occurred throughout Earth's history, such as the Tunguska Sibiria in 1908.
Archaeological excavations and surveys in other areas affected by the city indicate a sudden death of about 3,700 years ago, Silvia said. So far, craters have not been discovered, and it is unclear whether the culprit was a meteor or a comet that exploded above the ground.
The fact that only 200 square miles of land were destroyed indicates that the air flow was at a low altitude, possibly no more than 3,280 feet (1 km) above the ground, said Silvia. For comparison, the Tunguska air strike seriously damages 830 square miles or 2 150 square kilometers of land.
The team's results are preliminary and the studies are continuing, emphasizes Silvia. The team consists of members from Trinity Southwest University, Northern Arizona University, DePaul University, Elizabeth City State University, New Mexico Tech and Comet Research Group.
