The breakdown of a theory and the efforts to describe nature

Quantum theory and the general theory of relativity are the two celebrated discoveries of the twentieth century. The theory of gravity breaks down at Big Bang-the possible starting phase of the universe. Quantum theory is able to work in lower regimes of dimensions. If the predictions of quantum theory are correct, then it could provide a complete description of nature. Einstein-Podolsky-Rosen paradox implies that if local realism is accepted quantum theory is incomplete. The article is organized around the following questions: are the laws of Physics eternal truths? Is it possible to quantize gravity using a theory, which has inherent problems in its basic postulates? How could we speak of the properties of the universe while being part of it? Does nature want to hide her truths from us?
