There is no "Heaven" in Hinduism--any argument to the contrary is a thorough misunderstanding of Hindu culture. Whether the translator chooses to say "heavens", "the universe", or "outer space", the meaning of the word intended in the Sanskrit is undeniable.
Do you want to eat your words?? surely???
I have in the past given a detailed explanation of the Heavens in Hindu religion and didnt you read it??
According to traditional Hinduism (not your fringe psuedo Hinduism) the universe is divided into three lokas or three worlds - Heaven, Earth and Hell.
Heaven and earth are lumped together in the upper seven worlds known as vyahrtis and hell is the lower seven worlds collectively known as Patala.
The seven vyahrtis are bhu, bhuvas, svar, mahas, janas, tapas and satya.
The seven worlds of Patala are Atala, Vitala, Sutala, Talatala, rasatala, Mahatala and Patala
Each loka has a counterpart in the Tala.
satya loka's corresponding tala is Atala.
Tapas Loka's corresponding tala is Vitala.
Jana Loka's corresponding tala is Sutala and like wise.
detailed description of all these worlds can be found at Chakras - Lokas and Talas.
Arbitran, in Sanskrit and languages that derive from it, in all languages in India, except for urdu (which originates from persian), these words are the same.
maybe your sage/Swami friend of your uncle can disprove?
