In physical cosmology, the age of the universe is the time elapsed since the Big Bang. Astronomers have derived two different measurements of the age of the universe: a measurement based on direct observations of an early state of the universe, which indicate an age of 13.787±0.020 billion years as … Meer weergeven In the 18th century, the concept that the age of Earth was millions, if not billions, of years began to appear. Nonetheless, most scientists throughout the 19th century and into the first decades of the 20th century presumed … Meer weergeven The Lambda-CDM concordance model describes the evolution of the universe from a very uniform, hot, dense primordial state to its … Meer weergeven The problem of determining the age of the universe is closely tied to the problem of determining the values of the cosmological parameters. Today this is largely carried out in the context of the ΛCDM model, where the universe is assumed to contain normal … Meer weergeven Calculating the age of the universe is accurate only if the assumptions built into the models being used to estimate it are also accurate. This is referred to as strong priors and essentially involves stripping the potential errors in other parts of the model to render … Meer weergeven Since the universe must be at least as old as the oldest things in it, there are a number of observations that put a lower limit on the … Meer weergeven NASA's Wilkinson Microwave Anisotropy Probe (WMAP) project's nine-year data release in 2012 estimated the age of the universe to be (13.772±0.059)×10 years (13.772 … Meer weergeven In 2015, the Planck Collaboration estimated the age of the universe to be 13.813±0.038 billion years, slightly higher but within … Meer weergeven WebAnd the results seemed to indicate this initially. When the redshifts came in from distant galaxies, it has a H o of 526 kilometers per second-mega parsec (or km/(s*Mpc)), which translates to an age of 2 billion years for the universe.
