Abstract

The impact of expansion of the universe after the big bang is analyzed. The distance to remote galaxies is increasing which meant that the space between the galaxies and us is expanding. Hubble's law predicts that galaxies beyond a certain distance, known as the Hubble distance, recede faster than the speed of light. It is stated that the light beyond the Hubble distance would never reach us and the source would be forever undetectable until Hubble constant changes with time.
