This website provides the following translation of the Shlokas from the RigVeda:
"He made this Earth fixed by different devices like hills and mountains in shape of pegs but it still rotates . Sun never sets; all parts of earth are not in Darkness."
"There are suns in all directions, the night sky being full of them."
"There are planets in all directions, but only visible in night sky."
Although, neither does it provide the Shlokas or the references to them. I was wondering if anyone who has gone through the RigVeda can provide me with the original Shlokas.
