　　One the most famous cats in science must be the Schr?dinger’s cat in quantum mechanics, in which the cat can be either alive or dead at the same time, unless we look into the Schr?dinger’s box. The life of Schr?dinger’s cat has been puzzling the quantum physicists for over eight decades as Schr?dinger disclosed it in 1935. In this article, I will show that the paradox of the cat’s life is primarily due to the underneath subspace in which the hypothetical subatomic model is submerged within a timeless empty subspace (i.e., t = 0). And this is the atomic model that all the particle physicists, quantum scientists and engineers had been using for over a century, since Niles Bohr’s proposed in 1913. However the universe (our home) is a temporal space (i.e., t > 0) and it does not allow any timeless subspace in it. I will show that by immersing the subatomic model into a temporal subspace, instead a timeless subspace, the situation is different. I will show that Schr?dinger’s cat can only either alive or dead, but not at the same time, regardless we look into or not look into the Schr?dinger’s box. Since the whole quantum space is timeless (i.e., t = 0), we will show that, the fundamental superposition principle fails to exist within our temporal space but only existed within a timeless virtual space. This is by no means of saying that timeless quantum space is a useless subspace. On the contrary it has produces numerous numbers of useful solutions for practical application, as long the temporal or causality condition (i.e., t > 0) is not the issue.  In short, we found the hypothesis of Schr?dinger’s cat is not a physical realizable postulation and his quantum mechanics is timeless behaves like mathematics does. In which we see that his fundamental principle is timeless and not existed within our temporal universe.
