Rama Setu: Story, Truth And Science Behind The Stones

Ramsetu is internationally known as ‘Edames Bridge’. According to the Hindu religious text Ramayana, it is a bridge that was built on Rameswaram, the southern part of India, by the monkey army of Lord Shri Ram, the seventh incarnation of Lord Vishnu. The other side of the sethu connects to Mannar in Sri Lanka. It is believed that the stones used to build this bridge did not submerge in the seawater. Rather, they floated on the surface of the water. What was the reason that this stone did not submerge in the water? Some consider it to be a miracle of God, giving it religious importance, but when science argues, it is exactly the opposite. But a big question above this is ‘was there really a bridge called Ram Sethu’.

According to religious belief, the demon Emperor Ravana had taken Mother Sita with her to Lanka. To reach Lanka and take the Sita back, Sri Ram built a bridge in the middle of the sea with the help of monkeys. This was later called Rama Setu. It is said that this huge bridge was completed by the monkey army in only 5 days. It is surprising how the monkey army built a bridge in just five days to cross this sea between the two countries which have a distance of miles. To understand this in detail, the Ramayana composed by Maharishi Valmiki describes the construction of Ram Sethu.

Why Ram Sethu Was Constructed?

According to the Ramayana scripture, when Sri Lankan King Ravana, Shri Ram’s wife Sita was taken away to Lanka, Lord Sri Ram started searching for his wife. From Jatayu he finds out that his wife has been taken by a demon king who crosses a large sea miles away and lives in Lanka at the other end. Then Shriram decided that he himself would go to Lanka with his army and free everyone from the captivity of Ravana. In order to solve his difficulty, Shriram worshiped the sea god. But when the sea gods did not appear even after several days, then in anger, Shriram lifted his bow and arrow to dry the sea. Due to this move, the life of the sea started drying up. Then the sea god appeared in fear and said, “Shri Ram! With the help of your monkey army, you build a bridge of stones over me. I will take care of all these stones.”

Efforts of Nal and Neel (Two monkeys of Rama’s Army)

Sea God said to Ram, “There are two apes in your army named Nal and Neel, who are blessed with the boon of this art.  Nal, who is the son of Lord Vishwakarma is blessed by his father. With their help, you build a rigid bridge. This bridge will take care of all your army and will be able to take you to Lanka”. Saying that Samudra Dev made a humble request to Shri Ram to build the bridge. With the help of Nal and Neel, the entire Vanar Sena succeeded in making all kinds of plans.


In the end, the bridge building material was collected, choosing the plans. The entire monkey army succeeded in bringing stones, tree trunk, thick branches, and large leaves and shrubs from nearby. In the end, a huge bridge was built on the basis of Nal and Neel’s care and complete scientific plans. Scientists believe that Nal and Neel probably knew which stone would not be submerged in water by keeping it and how other stones would also be supported.

What is the Scientific Reason?

Therefore, after so many years of research, scientists have discovered the existence of stones used in Ram Sethu Bridge. Science believes that the stones used to build the Ramsetu bridge are some special types of stones, called ‘Pumais’ stones. Actually, these stones originate from the volcanic lava. When lava heat meets the atmosphere’s less hot air or water, they transform themselves into some particles. Many times these particles form a large stone. Scientists believe that when the volcanic hot lava meets the atmosphere’s cool air, the air balance deteriorates.

Spongy Stones

This process gives rise to a stone that has many holes. Due to the holes, this stone takes a spongy shape, making its weight less than normal stones. The holes in this particular stone are filled with air. This is why this stone does not sink quickly in the water because the wind keeps it up. But after some time, when slowly these pores are filled with water instead of air, their weight increases, and they start sinking into the water.

This is the reason that the stones of the Ramsetu bridge sank in the sea after some time and reached its terrain. The Ramsetu Bridge was discovered with the help of satellite by NASA. According to these photos, a bridge is actually shown that starts from Rameswaram in India and reaches Mannar Island in Sri Lanka. But due to some reasons, it has dissolved in the sea just a few distances from its beginning. In Rameswaram, some time ago people found some similar stones on the beach called Pumice Stone. People believe that these stones have come to shore along with the waves of the sea.
