Scientists from HKUST and Harvard-Smithsonian Center for Astrophysics discovered a method to observationally distinguish different theories of how the universe first began at its very early stage. The findings were accepted by the Journal of Cosmology and Astroparticle Physics.


The expansion of our current universe has been established for almost a century. However, concerning much earlier stages of our universe as how it began has always been a topic of contention among scientists. The most widely-accepted theory of the primordial universe is cosmic inflation, during which the universe was expanding at an extremely fast and mounting rate. On the other hand, there are also contending theories which believe that our infant stage universe was fast contracting, slowly contracting, static or slowly expanding. Read More...
