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:
“Old age and youth cannot live together.”
—Christina Stead (1902–1983)
“The age we live in is a busy age; in which knowledge is rapidly advancing towards perfection.”
—Jeremy Bentham (1748–1832)
“Beauty depends on size as well as symmetry. No very small animal can be beautiful, for looking at it takes so small a portion of time that the impression of it will be confused. Nor can any very large one, for a whole view of it cannot be had at once, and so there will be no unity and completeness.”
—Aristotle (384 B.C.–322 B.C.)
“To sum up:
1. The cosmos is a gigantic fly-wheel making 10,000 revolutions a minute.
2. Man is a sick fly taking a dizzy ride on it.
3. Religion is the theory that the wheel was designed and set spinning to give him the ride.”
—H.L. (Henry Lewis)
