The Royal Society of British Caves, in collaboration with Vietnamese scientists, measured Son Doong cave with the help of high-tech machines using lasers, devices that enable them to know the size of the limb. details of each " dead " corner in the cave - a cave specialist said.

The results show that Son Doong is bigger than Deer Cave in Borneo island of Malaysia, which is considered the largest cave in the world.

Deer Cave has an average size of about 91 mx 91 m, about 1.6 km long. Meanwhile Son Doong Cave in Phong Nha - Ke Bang National Park has an average magnitude of about 80 mx 80 m, which lasts about 4.5 km. But scientists suspect that Vietnam's Son Doong cave may be even deeper because the 2009 expedition was stopped at a depth of 4.5 km due to floodwaters.

In addition, in some sections of Son Doong cave, there are 140 mx 140 m large, including stalactites up to 14 m high. A magnificent photo taken by photographer Carsten Peter in May 2010 depicts a cave section with a width of about 91.44m, a high arched cave near 243.84m - which can accommodate a 40-storey building of New York City (America).

In the cave, the researchers also found an underground river of 2, 5 km long and even stalactites up to 70 m high.

It is known that Son Doong limestone cave mouth was found by a farmer a few years ago, but until April 2009 it was discovered. The cave is located deep in the old forest in a quite rugged terrain, far from the road and undetectable on Google Earth.

British explorers said that before that cave could be explored by some local people, they only stopped at a depth of several hundred meters for fear of going deep inside. In the cave there are a number of poisonous centipedes living and the monkeys often crawl through some heavenly gates at an altitude of about 300 m into the cave to find snails.

The discovery of Son Doong cave has attracted the attention of many explorers in the world. The British Royal Expedition is expected to return in later years to continue exploration.
