Modern astronomy describes a universe that is billions of light-years in extent. If we reasonably assume that a light-year is the distance that light travels in one year at one light-year per year and that the speed of light has been a constant over all time since the creation of the Universe then creationists have a problem, don’t they? Since the Universe was created only a mere 6 thousand years ago how can light travel billions of light-years? This is called a light-travel-time problem.
Despite increasingly compelling arguments from biblical creationists that offer solutions to this problem, still many doubt the Bible’s clear timescale. This is because, they think, it is impossible for light to have reached Earth in only a few thousand years from galaxies that are billions of light-years away. This misconception is often the ultimate stumbling block to a straightforward acceptance of the Bible—even the gospel itself.
This book, Starlight, Time, and the New Physics, provides one such solution and it is summarized below. But before proceeding know this, the most accepted model describing the origin of the universe in the hot big bang also has a light-travel-time problem. This is called the horizon problem. See my blog, Big bang has a light-travel-time problem.
