If Govardhana Mountain is mentioned as 8 Yojanas in Veda Vyasas(Krishna Dvaipayana) Bagavatham then it must be true. The world is nothing then change, name, size and everything will change only obsolute consiousness remains. The size of man changed, country names changed plants name, languages many changed then there might be change in Govardhan Mountain size and name.
