Abstract:

We introduce the concept of parallel universes through two aspects of surveying. From macroscopic view, the ancient puzzle of star distance measuring, which is caused by the vanishing of star parallax, is reviewed. Then, standard candlelight distance measurement with cepheids and the redshift determination proposed by Hubble are introduced to measure the distances of stars. The latter helped Big Bang theory defeated the hypothesis of steady state universe. Then, the theory of Inflationary Universe leads to the first and second layer of parallel universes. From the microscopic view, we first introduce the failure of Newton’s alchemy, which leads the four fundamental forces and quantum mechanics. The measurement uncertainty of microparticles and the Schrodinger equation for the wave function are further discussed. The mainstream interpretation of wave function is the standard Copenhagen interpretation. However, the many worlds interpretation presented by Everett, which leads to the parallel universes of quantum mechanics, has been widely recognized.
