By exploring the size of the Universe are we trying to catch the tail of a wave that is running away fron us? According to Hindu belief, the time is made of cycles called "yugas"; Is it possible that after the current "yuga" called "kaliyuga" ( some close to 500000 years or let's just assume a vast number in millions of years) there will contraction phase of the wave and the wave to be repeated again and again? If so, can human intelligence and analysis with all the logic based on finite existence, ever capable of describing the Universe?

Of course, I am referring to the spiritual space that can be described to confirm with scriptural meaning of God and God's kingdom as well as the explanations of the same by spiritual teachers, prophets and incarnations that have been in existence so far in the history. I am also thinking of a mathematical formulation because mathematics, to my understanding is absolute representation of the quantifiable physical space just as God's space is understood to be absolute.
