Rama Sethu or Adam's Bridge

This is one of very interesting and curious subject for anybody who knows about Indian Mythology & puaranas. The space images taken by NASA shows a mysterious( I believe for the people who know about Indian mythology it's not mystery) bridge between India and Srilanka, Which is mentioned in Ramayana (one of the two great epics of India).
NASA named this bridge as Adam's bridge(I donno why, NASA linked this bridge to Adam)

I would like to share some of the material which i came across & which i feel is logical(PS:My personal thought... no offence to anybody).

Correlations between Hindu Cosmology, Sea Level Curves and African -Asian Hominid Dating
By Malcolm P.R. Light

A sea level variation curve from about 8 million years ago to the present day (Late Miocene to Recent - Eberli, 2000) is compared in Figure 1 to the time of construction of Adam�s Bridge between southern India and Sri Lanka, Hindu cosmological dates and African Asian chronological data. There are a number of clear correlations between the Hindu cosmology, the sea level curve and the geochronological data.

  • Each of the Yuga cycles (Das 2004) appears to correspond to a major cycle in sea level change. The Satya/Kriti Yuga is preceded by a long period of rising sea level in the Late Miocene but sea level began to fall sharply during this Yuga reaching a minimum of -80 metres below mean sea level around 2.7 million years ago (Figure 1 Eberli, 2000). During the Late Miocene, early arboreal apemen, Sahelanthropus tchadensis (Toumai), Orrorin tugenesis and Ardipithecus ramidus kadabba lived in the extensive thick forests in Africa (Brunet et al. 2002; Wood, 2002; Pickford 2001; Aiello and Collard, 2001; Haile Selassie 2001; Senut et al 2001; White et al. 1994; Wood; 1994). The following Treta Yuga represents a period of rising sea levels during which Hindu cosmology said there was increased rainfall and the formation of new rivers (Das 2004). The Dvapura Yuga is a period of falling sea level, followed by a rise at the beginning of the Kali Yuga (Das 2004, Eberli 2000).
  • At the start of the Satya/Kriti Yuga, 4.3 million years ago (Das 2004) there was a general period of falling sea level (Eberli 2000) and major climate change in Africa during which the vegetation began to alter from thick forest inhabited by 4.4 million year old arboreal Ardipithecus ramidus ramidus to dry woodland and gallery forest inhabited by the 4.2 million year old Austrolopithecus anamensis (Leakey et al. 1995; White et al, 1994). By the end of the Satya/Kriti Yuga some 2.7 million years ago (Das 2004), sea level had reached its lowest level some 80 metres below the present sea level and the woodlands were still in habited by Austrolpithecines (Figure 1 Eberli 2000; Leakey and Lewin 1979; Gowlett 1984).

  • The start of the Treta Yuga (2.6 million years ago) when man began to pursue knowledge (Das 2004) corresponds exactly with the time the first tools appeared in Africa. These tools were made by the newly evolved upright hominids, Homo habilis and later Homo erectus (Foley 2003; Leakey and Lewin, 1979) who now inhabited the harsher savanna consistent with the description of the conditions in the Treta Yuga (Das 2004). Homo erectus began to migrate out of Africa because of increasing aridity in the rift savanna between 2 and 1.8 million years ago into Asia (Leakey, 1994; Leakey and Lewin 1979; Templeton, 2002) and India (Joseph 2004).
  • Hanuman, the monkey God in the Ramanyana (Joseph 2004), must have been Homo erectus and this hominid species would certainly have seemed ape-like to modern day man. They were the ancestors of Pekin man in China (Wolpoff and Caspari 1977), the 1.6 million year old Homo erectus in Java and probably the 18 thousand year old hobbits recently found on Flores island (Stringer, 2004; Dalton, 2004). Adam�s bridge appears to have been constructed between southern India and Sri Lanka 1.8 and 1.6 million years ago in the Treta Yuga during a period of sharp sea level fall to some 60 metres below the present sea level (Figure 2; Eberli 2000).
  • A strip of land must have been exposed between India and Sri Lanka as the sea level approached its lowest level, between 1.8 and 1.6 million years ago. Because Homo erectus had already reached southern India before that time he must have tried to get across to Sri Lanka when the land began to be exposed at low tide during this period of sea level fall, around 1.75 million years ago (Joseph 2004). The driving force for his migration was probably population pressure within the southern Indian forest which caused food shortage. The exposed region between southern India and Sri Lanka must have been a treacherous path with many quicksands and shallow lakes. It seems logical that after several of his company were lost during periods of rising tide, Homo erectus could have started to construct a causeway by throwing trees and other vegetation onto the loose sand and and covering them with rocks. Homo erectus must have built the floating bridge on the quicksands that is so elegantly described in Sage Valkimi�s account of the �Ramanyana �(Joseph 2004). Nala son of Vishvakarma (architect of the demigods) constructed a causeway - magnificent with its wonderful paved floor - like unto a line traced on the waves�(Joseph 2004).
  • The Adam�s Bridge causeway must have been a major engineering feat for its thin trace is still so clearly visible on the present day satellite images (Joseph 2004). It has resisted the relentless erosion of the sea for almost 2 million years and it attests to the great engineering skills of the ancient Indian people. It is the earliest and largest carbon-fibre reinforced civil engineering structure known to man and should be protected as a world heritage site. A shallow seismic survey could be used to detect the strong reflection acoustic signal of lignite formed from decayed wood in the framework of the causeway and this will guide later drilling programs where the actual structure of the causeway could be investigated.
  • In addition to the above correlations, one Brahma day (4.32 billion years)(Das 2004) is close to the value for the age of the Earth (4.6 billion years)(Lide 1994). One cycle of our Universe from Big Bang to Big Crunch assuming a Universe age around 15 billion years is 30 billion years almost identical to 1/100 of a Brahma year (31.1 billion years)(Das 2004). One Brahma year is 3.11 trillion years (Das 2004). Note the length of a Yuga cycle (and the start of the Satya/Kriti Yuga) at 4.3 million years is 1/1000 of a Brahma day (Das 2004).
