The "big bang" is a concept that makes sense to most science-minded persons; evidently, the explanation for the entire universe is that it all was created in an instant from one subatomic particle.
Leaving the logic of the big bang for the moment, it was refreshing and exciting to discover this article about the new scientific thinking regarding the age of the universe.

Essentially, the scientists have redated the age of the universe to about 13 billion years. And, interestingly enough, The Urantia Book is in agreement. Here are the pertinent dates, which I took from our Timeline feature
200,000,000,000 B.C. - A time of contraction and condensation in the Andronover nuclear mass. Some planets revolving around the newborn suns have cooled sufficiently to be suitable for life implantation. The oldest inhabited planets of Nebadon date from these times. The completed universe mechanism of Nebadon first begins to function; Michael's creation is registered on Uversa as a universe of inhabitation - (The Urantia Book, 57:3.10; 57:3.11)
75,000,000,000 B.C. - The Andronover nebula has attained the height of its sun-family stage. The majority of these suns have since developed extensive systems of planets, satellites, dark islands, comets, meteors, and cosmic dust clouds - (The Urantia Book, 57:4.2)
50,000,000,000 B.C. - The first period of sun dispersion in the Andronovre nebula is completed, giving origin to 876,926 sun systems - (The Urantia Book, 57:4.3)
7,000,000,000 B.C. - The height of the Andronover terminal breakup, the period of the birth of the larger terminal suns and the apex of the local physical disturbances. The Milky Way galaxy is composed of vast numbers of former spiral and other nebulae, and many still retain their original configuration. But as the result of internal catastrophes and external attraction, many are so distorted and rearranged that these enormous aggregations appear as gigantic luminous masses of blazing suns, like the Magellanic Cloud. - (The Urantia Book, 15:4.8; 57:4.7)
You'll see that these quotes cover the times between 7 billion years to 200 billion years, and I think you'll find it all fits quite nicely...with those immense time spans, I think we can allow a bit of leeway...
