All space scientists know that the "space" Sunita and several other astronauts "explored" was of an infinitesimally small depth. Man can never, never know the full depth of the universe. The phrases like "20 billion light years away" and "space-time curvature" and "Big Bang and big crunch" etc. have fooled mankind for decades, and so called scientists got away with Nobel Prizes, but not one of them was honest enough to clearly point out the futility of space exploration, and the gargantuan waste of resources and time of human beings on this shrewdly presented "science".
