Ram Setu, also known as Adam's Bridge or Rama Setu, stands as a fascinating link between myth and history. This chain of limestone shoals connects Pamban Island in Tamil Nadu, India, to Mannar Island in Sri Lanka. The structure holds immense significance in Hindu mythology and finds mention in the epic Ramayana. However, it has also captured the curiosity of scientists, who seek to unravel its origins and age.
Recent developments have spurred interest further, as the central government approved an underwater exploration to study the structure, seeking to determine its age and formation and possibly establish its connection to the Ramayana period. Additionally, there is a contentious demand to declare Ram Setu a national monument, which is currently under legal consideration.
The Proven Facts about Ram Setu Bridge
Ram Setu is a 50-kilometer-long structure resembling a causeway, separating the Gulf of Mannar from the Palk Strait. Some parts of the bridge are dry, and the sea around it is quite shallow, ranging from three to thirty feet deep.
Geological evidence indicates that the bridge once served as a land connection between India and Sri Lanka.
Several scientific reports suggest that the bridge was above sea level until 1480, when a cyclone damaged it. After this event, the region became impassable on foot and challenging for ships to navigate.
The bridge is composed of limestone shoals and coral reefs, and it is believed to have formed from floating rocks found scattered across Rameswaram. Some theories even suggest that volcanic rocks can float on water.
Oceanography research indicates that the bridge could be around 7,000 years old, corresponding with carbon dating results from nearby beaches.
According to one theory, the Palk Strait and Gulf of Mannar were once part of the Kaveri River basin, and tectonic shifts led to the formation of the bridge and other landforms.
Ram Setu's Mythological Significance
As per Hindu mythology, Ram Setu was constructed by Lord Rama's Vanara Sena, led by Lord Hanuman, to facilitate Rama's journey to Lanka to rescue his wife, Sita, from the clutches of the demon king Ravana. Legend has it that the bridge was built using floating stones, each bearing Lord Rama's name, making it unsinkable. The epic Ramayana mentions the construction and significance of the bridge, dating back to ancient times.
The Mystery Continues
Despite the geological evidence and mythological tales, there remains an ongoing debate over whether Ram Setu is a natural formation or a man-made marvel. Satellite imagery by organizations like NASA shows a chain of sandbanks, but it does not offer conclusive evidence either way.
Ram Setu continues to captivate the world, with its historical, mythological, and geological aspects intertwined. The underwater exploration and ongoing research may shed further light on this ancient wonder as people around the globe seek to connect Indian mythology with present-day structures. Until then, the allure of Ram Setu remains a subject of intrigue and wonder.
