Our religious scriptures explained many years back but our scientists found recently.We,many of us,presently thinking that our religions and religious telling were old and no science can prove the religions and religious thinking are all just waste in the modern scientific wold etc., But thee are documentary evidences proving the present scientific information are told already in our epics before hundreds and thousands years.
1) I read in facebook (https://www.facebook.com/?ref=tn_tnmn)
One of the sanskrit sloka on Hanuman in forty slokas which is called as Hanuman chalisa,written by Tulsidaas,contains in its eighteenth line as Yuga sahasra Yojana Para Bhaanu! SeelayO thahi mathura bala jaanu! Here Bhanu means sun and the distance between sun and earth is one yuga sahasra yojana where one yuga counts 12000, sahasra means 1000 and one yojana counts eight miles that is 1.6 KM. so, the calculation is 12000x 1000 X 8 = 96000000 X 1.6 km = 1536000000 KMs. The same has been announced by NASA in the year 2001 which has been told by our Indians before 400 years in few words.
2)The layer of ozone is being discussed all over the world since many years. World ozone day has been celebrated since 1994 and is mainly intended to spread the awareness of the depletion of the ozone layer. But how many of us know that the same has been revealed before 700 years as depicted in Sri Meenakshi temple of Madurai. refer:http://www.deccanherald.com/content/509930/visit-meenakshi-temple-study-ozone.html
3) The Holy Quran in its verses 78:6,43:10, the layers of our earth has been clearly defined as core, Mantle and crest layers with their specifications. Further, verse 21:44 tells about the reduction of edges of our earth in all directions but the same is found by scientists only in recent days.
