Dr. Gentry is a convinced young earth{1} creationist (and pusher of that idea).

Lambert Dolphin, who posted that static universe paper, has his own favorite alternative theories. Light speed decays continuously, drastically in the past, and this leads to vast differences between atomic time (based on light frequencies) and dynamic time (based on astronomical events and the calendar).{2}

Dig this conversion table from the paper pointed at by the next link below:
----------------------------------------------------------
1 million years before present (BP) atomically is actually 2826 BC with c about 70,000 times c now.
63 million atomic years BP is an actual date of 3005 BC with c about 615,000 times c now.
230 million atomic years BP is an actual date of 3301 BC with c about 1.1 million times c now.
600 million atomic years BP is an actual date of 3536 BC with c about 2.6 million times c now.
2.5 billion atomic years BP is an actual date of 4136 BC with c about 10.8 million times c now.
4.5 billion atomic years BP is an actual date of 4505 BC with c about 19.6 million times c now.
15 billion atomic years BP is an actual date near 5650 BC with c about 65.3 million times c now.
20 billion atomic years BP is an actual date near 5800 BC with c about 87 million times c now.

What very important event do you suppose all that points back to?

implications of a non-constant velocity of light
in case you didn't guess the answer to my last question -->

what holds the universe together?

{1}Maybe I should say "young universe creationist".
{2}EA Milne (kinematic relativity) entertained the idea of two time scales, only he called them kinematic time and dynamic time.
