Theory of Age of The Universe
Isaac states that the universe is actually 15,340,500,000 years old. Isaac arrived at this conclusion by distinguishing between earthly "solar years" and "divine years," based on a verse from Psalms, which states that "A thousand years in Your sight are but as yesterday" (Psalm 90:4). If each day of a divine year is equal to a thousand earthly "solar years," then a divine year would be 365,250 years long. Isaac then makes some other calculations based on the Talmud and the Biblical sabbatical year, and arrives at the said number. The scientific estimation places the occurrence of the Big Bang at 13.7 ± 0.2 billion years ago.

Famous quotes containing the words the universe, theory of, theory, age and/or universe:
“The more the universe seems comprehensible, the more it also seems pointless.”

“Thus the theory of description matters most.
It is the theory of the word for those
For whom the word is the making of the world,
The buzzing world and lisping firmament.”
—Wallace Stevens (1879–1955)
“No one thinks anything silly is suitable when they are an adolescent. Such an enormous share of their own behavior is silly that they lose all proper perspective on silliness, like a baker who is nauseated by the sight of his own eclairs. This provides another good argument for the emerging theory that the best use of cryogenics is to freeze all human beings when they are between the ages of twelve and nineteen.”
—Anna Quindlen (20th century)
“An age and a faith moving into transition,
the dinner cold and new-baked bread a failure,”
—Alfred Wellington Purdy (b. 1919)
“The universe is not rough-hewn, but perfect in its details. Nature will bear the closest inspection; she invites us to lay our eye level with the smallest leaf, and take an insect view of its plain. She has no interstices; every part is full of life.”
—Henry David Thoreau (1817–1862)
