Secrets of the Universe

Cosmologists and Astrophysicists hope to find Gods existence through empirical measurements and scientific discoveries of the Universe. This has always been the underlying goal of scientists from Galileo to Einstein. But physical measurements are finite by nature, so this cannot lead to the understanding of the infinite, that is the Brahman, because a finite effect cannot define an infinite cause. Scientific discoveries of matter, particles, etc are all finite by nature because they decay and thus have no constant form. If the expanding Universe is in a constant progression, how can any emperical science ever understand its true composition?
