The evolution of our Universe from Big Bang
(an introduction to the First Source of light in the Universe)
According to the current consensus in physical cosmology, the first source of light (referred as the First stars or primordial stars) are believed to have formed four-hundred million years after the Big Bang. The studies of primordial stars can provide crucial information about the early universe and how it has been evolved into what we observe today. The emergence of the very first stars has therefore become an important topic of research in modern astrophysics and cosmology. We have developed a high-resolution cosmological hydro- dynamical (SPH) simulations to investigate whether the First stars can survive for 13.7 billion years, and hence, may even be found in our Milky Way galaxy.
