Understanding the unnaturally small size of the cosmological constant poses one of severest challenges for a theory of gravity. At late times and for large distances, the apparent size of the cosmological constant is constrained to be extremely small in terms of the natural scale for gravity, the Planck mass. In contrast, no observations bound … Continue reading Importance of Cosmological Constant

# Cosmological Constant and its Significance

Abdul Najeeb asked via Facebook: Would you plz explain me what is a cosmological constant? When Einstein snubbed it as the "biggest blunder" in his life, what else is the real importance of the constant? Also what is cosmological acceleration and its' effect on the constant...plz...but in simple words...plzzzz:))))) Ans: The cosmological constant was proposed … Continue reading Cosmological Constant and its Significance
