Dr. Aravinda Ravibhanu Sumanarathna is the Founder of the Eco Astronomy Sri Lanka called South Asian Astrobiology & Earth Sciences Research Unit. He has introduced the term - Eco Astronomy ( ජෛව තාරකා විද්යාව) in  2012. He is a vigorous supporter of the many-worlds interpretation of “Union of the General Theory in Eco Astronomy Mechanics & Concept”. EcoAstronomy is scientific study of extreme environmental conditions that effecting to the Harbor Life. Also, he has introduced virtual development of “Speleothem Dimensions” for calculate deviation of average formation section in Stalagmite & Stalactites.  Aravinda Ravibhanu is a Life fellow of the United Nation Organization (SL). The Eco Astronomy Inc, originally established in 2018 as a Distance Learning Education and Research Institute.
