A graduate student at my university, contacted me recently about the biblical creationist starlight-travel-time problem. He said that he had attended a lecture on the recent detection of gravitational waves, where the professor had mentioned that the source of the binary black hole collision event occurred some 1.3 billion years ago. The issue has made him contemplate how that time scale fits with the biblical time scale of an approximately 6000 year old universe.
In response first I pointed out that the standard big bang model also has a light-travel-time problem called the horizon problem. It may be over a different time scale but it is still the same type of problem.
I explained that there were different biblical creationist models, in 5 different categories. I also suggested he view this lecture, which I gave last year on the problem, with lecture notes found here. I have looked at various solutions, and proposed a few myself, which I mention in the lecture, but now I personally prefer the solution outlined here, with details found in the linked articles there.
I asked him, in relation to how he understands the ASC model, if he could write a paragraph, in his own words, describing how it explains the starlight-travel-time problem. This is what he wrote. Continue reading
