 Deep sky, how much of its depth and height
no one can answer this question of "how this universe is horizontally big, and vertically how much it is long". thousands of years later also the answer will be unanswered.
there were mostly two objects in this space before the big bang happened, may be that two objects covered the whole portion of this or partly of the sky. there are many possibilities. later the bigbang theory was accepted by the world, but yet many questions are unanswered.
what is your opinion about this sky.
will its blue color remain forever..
