Aravinda Ravibhanu Sumanarathna is the one who founder of the Eco Astronomy Sri Lanka called South Asian Astrobiology & Earth Sciences Research Unit. He is a vigorous supporter of the many-worlds interpretation of Eco Astronomy mechanics in first time. Ravibhanu was the first to set out a harbor life explained by a union of the general theory Eco Astronomy mechanics & concepts.

Eco Astronomy is the scientific study of extreme environmental conditions, effecting to the Harbor Life . The life origin, evolution existence of life in the universe related to harbor life concepts, means safe place providing refuge, comfort and sustainable harbor environment to any object. Eco Astronomical research has implemented focusing - “Comparative systematic analysis of extreme environmental conditions of planet earth, which based on Paleontological & Petrological factors. Therefore, this disciplines representing as a kin subject to interpreting comparative model for any Harbor Life”.

Also He introduce virtual development of Speleothem Dimensions for calculate deviation of average formation section in Stalagmite & Stalactites. Ravibhanu is  a life fellow of the United Nation Organization.
