Albert Einstein's cosmological constant was proved wrong by Hubble as he proved the universe is expanding so it doesn't need a constant to stop it imploding.
As far as I understand, the projected age of the universe is about 99.5% of the estimated "Hubble time". The age is projected by applying a correction factor to the inverse Hubble constant. The correction factor applied depends on the value of the cosmological constant. The constant is derived from WMAP observation data, and valued at 0.976. For a flat universe without cosmological constant, the value would have been 0.666, resulting in a projected age 66.6% of the Hubble time.
According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.

The big bang theory is a cosmological model. Is this really the question you are trying to ask?
The "cosmological constant".
A zero graph
It will expand more rapidly.
Einstein used approximation methods in working out initial predictions of the theory. Einstein later declared the cosmological constant the biggest blunder of his life.
The gravitational constant was derived experimentally. Until recently, it was believed that it was a universal constant. However, developments in cosmological theories suggest the possibility that it is not a constant.
A huge structure of pulsars/quasars which defies the cosmological constant.
The brief layman's answer: Einstein was troubled because his own theories of relativity did not support the idea of a constant universe, the universe that he preferred to believe existed. His equations showed that a steady state universe would eventually give in to the forces of gravity. He developed the cosmological constant, basically a 'fudge factor', so that his theories could support a steady-state universe. Shortly after, Hubble's redshift observations provided evidence that the universe is expanding, and Einstein called the cosmological constant the worst blunder of his life. Ironically, interest in the cosmological constant is returning, as a possible way of explaining the acceleratingexpansion of the universe.

Its not that he couldn't, he eventually did and declared his "cosmological constant" the biggest mistake in his life.The situation was when Einstein developed General Relativity the prevailing cosmological theory was the Steady State Theory, that the universe was static. However General Relativity predicted that the universe could NOT be static: it must be either expanding or contracting. To correct for this apparent "error" and conform to the prevailing theory, Einstein added an arbitrary fudge factor that he called the "cosmological constant" that could be tweaked as needed to keep the General Relativity predictions in accordance with the Steady State Theory.When it was clearly shown that Hubble's data was right and the universe was expanding, he willingly deleted the "cosmological constant" from Relativity.

There are hundreds of things named after Albert Einstein. Among them are Boseâ??Einstein statistics, Einstein's constant, Einstein's radius of the universe,Einstein coefficients, and Einstein cosmological constant to get the list started.
Adding the cosmological constant to his Theory of General Relativity.More Information:Something keeps the universe expanding at an accelerating rate, we call this something unseen force or dark energy.After measuring and studying the effects of this energy, it appears that it has been a constant force for the entire life of our universe. This force may be something that emanates from spacetime itself. - - A constant force!? - - Maybe a cosmological constant!? - - He may not have understood it or properly quantified it, or even believed in it, but maybe Einstein got it right.
