Age and Size of The Cosmos
According to current scientific theory, the cosmos began 13.7 billion years ago short scale in the Big Bang. The current diameter of the observable cosmos is thought to be about 93 billion light years.
The diameter of the entire cosmos is unknown. However, according to Alan Guth's inflation theory, the actual size of the cosmos is at least fifteen orders of magnitude larger than the observable universe. This means that if the inflation theory is correct, the 93 billion light year diameter of the observable universe is approximately as much smaller than the diameter of the entire universe as the diameter of a helium atom is compared to the diameter of the Sun. This is equivalent to a minimum diameter of the entire cosmos of 1026 light years (100 septillion light years short scale).

Famous quotes containing the words age and, age, size and/or cosmos:
“[The public has] the habit now of invalidating opinions emanating from me by reference to my age and infirmities.”
—James Madison (1751–1836)
“Virginity is now a mere preamble or waiting room to be got out of as soon as possible; it is without significance. Old age is similarly a waiting room, where you go after life’s over and wait for cancer or a stroke. The years before and after the menstrual years are vestigial: the only meaningful condition left to women is that of fruitfulness.”
—Ursula K. Le Guin (b. 1929)
“Learn to shrink yourself to the size of the company you are in. Take their tone, whatever it may be, and excell in it if you can; but never pretend to give the tone. A free conversation will no more bear a dictator than a free government will.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The cosmos is about the smallest hole that a man can hide his head in.”
—Gilbert Keith Chesterton (1874–1936)
