Space images taken by NASA reveal a unknown ancient bridge in the Palk Strait between India and Sri Lanka. The bridge currently named as Adam's Bridge is made of chain of shoals, c.18 mi (30 km) long.
The bridge's unique curvature and composition by age suggests that it may be man made. The legends as well as Archeological studies reveal that the first signs of human inhabitants in Sri Lanka date back to the primitive age, about 1,750,000 years ago.

Some Unsolved Mystery in world !!!

 

Do Yeti really exist

One of the greatest mysteries of Himalayas is Yeti, an ape like creature which is supposed to roam the snow capped mountains of the area. Over the last more than hundred years, various mountaineers have claimed seeing a yeti or his foot prints in the snow which was of double the size of a human foot. But no conclusive evidence could be found to establish the authenticity of these claims. On the other hand there has been no conclusive theory to prove the yeti a part of folklore or legend as well. It continues to intrigue the mountaineers visiting the Himalayas.

Who created the statues of Easter Island

 

Easter Island is an island situated in Pacific Ocean. The place is a famous tourist spot as well as a source of puzzle due to 887 statues erected there. There is no conclusive evidence to say
who created these statues. They are a long as 30 feet and weigh in tons. It is difficult to ascertain how these statues were made on this remote island in the time when there was no sophisticated machinery was available. Few people opine that it was the work of extraterrestrials but yet again there is no clear answer to the question.

Bermuda Triangle Mystery Solved

The Bermuda Triangle, also known as the Devil's Triangle, is a region in the western part of the North Atlantic Ocean where a number of aircraft and surface vessels are said to have disappeared under mysterious circumstances. Popular culture has attributed these disappearances to the paranormal or activity by extraterrestrial beings.^[1] Documented evidence indicates that a significant percentage of the incidents were spurious, inaccurately reported, or embellished by later authors. Contrary to popular belief, insurance companies don't charge higher rates for passage through this area.

 
 Computer studies of ocean floors around the world, particularly the area known as The Bermuda Triangle, reveal evidence of massive methane explosions in the past. For years, believers in the paranormal, aliens, and other outlandish theories pointed to the the disappearance of ships and aircraft as an indicator of mysterious forces at work in the "Devil's triangle." Scientists have finally pointed the rest of us to a more plausible cause.

The presence of methane hydrates indicates enormous eruptions of methane bubbles that would swamp a ship, and projected high into the air- take out flying airplanes, as well.

Any ships caught within the methane mega-bubble immediately lose all buoyancy and sink to the bottom of the ocean. If the bubbles are big enough and possess a high enough density they can also knock aircraft out of the sky with little or no warning. Aircraft falling victim to these methane bubbles will lose their engines-perhaps igniting the methane surrounding them-and immediately lose their lift as well, ending their flights by diving into the ocean and swiftly plummeting.
