I rarely comment on other’s videos. But in this case I felt compelled to do so. About 1 year ago I saw this Issachar Insight video of a discussion between Chuck Missler and Barry Setterfield regarding Setterfield’s physics. Please don’t interpret the following as being critical of a Christian brother, but of his theory only.
Barry Setterfield on Chuck Missler show
I know Mr Setterfield is a biblical creationist and he has developed his own ideas on various aspects of alternative physics to promote, in his mind, that the speed of light (c) was much faster back at Creation than it is now. The speed of light, c, allegedly slowed down to its current value, from the Creation to the present time, by a factor of something like 10 million times. This is referred to as c-decay or cdk.
His idea I once found very exciting as a potential solution to the biblical creationist starlight travel-time problem. That was about 1980 and since then we have learned that basic experimental physics in the cosmos undermines it. The new detection of gravitational radiation from the merger of a black hole binary further strengthens the case against it.

The discovery of gravitational waves
Figure 1: The gravitational-wave event GW150914 observed by the LIGO Hanford (H1, left column panels) and Livingston (L1, right column panels) detectors. Times are shown relative to 14 September 2015 at 09:50:45 UTC. For visualization, all time series are filtered with a 35–350 Hz bandpass filter to suppress large fluctuations outside the detectors’ most sensitive frequency band, and band-reject filters to remove the strong instrumental spectral lines. Top row, left: H1 strain. Top row, right: L1 strain. GW150914 arrived first at L1 and 6.9 ms later at H1; for a visual comparison, the H1 data are also shown, shifted in time by this amount and inverted (to account for the detectors’ relative orientations). Second row: Gravitational-wave strain projected onto each detector in the 35–350 Hz band. Solid lines show a numerical relativity waveform for a system with parameters consistent with those recovered from GW150914 confirmed to 99.9% by an independent calculation (details in original). Shaded areas show 90% credible regions for two independent waveform reconstructions. One (dark gray) models the signal using binary black hole template waveforms. The other (light gray) does not use an astrophysical model, but instead calculates the strain signal as a linear combination of sine-Gaussian wavelets. These reconstructions have a 94% overlap. Third row: Residuals after subtracting the filtered numerical relativity waveform from the filtered detector time series. Bottom row: A time-frequency representation of the strain data, showing the signal frequency increasing over time. (Caption edited from the original, Ref. 6.)
On 14 September 2015 at 09:50:45 UTC the two gravitational wave detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO)—one at Hanford, Washington and the other at Livingston, Louisiana—simultaneously observed a transient gravitational-wave signal. The signal exhibited the classic waveform predicted by Einstein’s general relativity theory for a binary black hole merger, sweeping up in frequency from 35 to 250 Hz, and exhibited a peak gravitational-wave strain of 1.0 × 10−21 at the detectors.1
The two detectors recorded the same signal, which matched the predicted waveform for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. The signal was observed with a matched-filter signal-to-noise ratio of 24 and a false alarm rate estimated to be less than 1 event per 203,000 years, equivalent to a statistical significance greater than 5.1σ (where 1σ represents 1 standard deviation).2 In other words, the detection is highly likely to be real.
The source lies at a luminosity distance of about 1.3 billion light-years corresponding to a redshift z ≈ 0.09.3 The two initial black hole masses were 36 M⊙ and 29 M⊙,4,5 and the final black hole mass is 62 M⊙, with the equivalent of 3 M⊙ radiated as gravitational waves. The observations demonstrate for the first time the existence of a binary stellar-mass black hole system but, more importantly, the first direct detection of gravitational waves and the first observation of a binary black hole merger.

I received the following question on the Anisotropic Synchrony Convention (ASC) a timing convention. The ASC is a timing convention used in biblical creationist models of Jason Lisle and myself. It relies on the language of appearance, that the Author of the events in Creation week used such language in describing when events occurred. God said He made the stars on Day 4, so if any observer was on the earth then (which there wasn’t, of course) he would have seen the stars appear in the night sky of that day. Read the Related Reading below for a full explanation. The writer’s comments are in blue indented text and my response in grey text.
I have been ruminating and now I am ventilating. :^)
Intellectuals who study the heavens are the modern priests of the religion of Science. They speak to the world through esoteric formulas, computers, telescopes, satellites, space probes, deep solar system images, and advanced degrees that few humans can attain to but which are the credentials of entrance into a very elite religion. These modern priests step out of their ivory towers with scientific pronouncements based upon data that 99% of the population has no means of refuting, or even discussing. They are on the cutting edge of discovery and unbiased reality and matter-of-fact truth. Words from an ancient book, the youngest writings of which are nearly 2000 years old, coming from a time when transportation at its best was by foot or animal or wind, are impartially assessed as archaic, factually shallow, imaginatively intriguing, but, in veracity, vacuous. Miracles of authenticity in 2016 come from science, but the miracles of God are only found on the pages written in the progressively improbable antiquated past. Continue reading
The universe is truly vast; tens of billions of light-years in size. If the universe is only about 6000 years old how do we see galaxies at all, which are more than 6000 light-years away? This is the biblical creationist starlight travel time problem. I present 5 categories wherein potential solutions may be found. Besides the big bang also has a light travel time problem—the horizon problem—besides many other various problems.

A YEC scientist questioned Jason Lisle regarding his choice of the Anisotropic Synchrony Convention (ASC) in his cosmological model. That scientist believes that the Einstein Synchrony Convention (ESC) is the more natural choice and correct choice for the cosmology of the Universe as well as the one that the biblical language uses. Dr Jason Lisle responds with the following.
For the sake of time, this will have to be my last clarification on the matter. But I’ll try to answer your most relevant questions and comments. Regarding your comment that “ASC says nothing about reality,” that would require some clarification. Both ESC and ASC are coordinate systems that describe the same underlying reality. (Perhaps that’s what you meant.) But the fact that either can be applied with equal legitimacy, each making correct predictions in regard to any relativistic experiment or observation, says something quite profound about reality. Namely, the universe is non-Newtonian, and our measurements of time and space are necessarily observer-dependent. As a result, one-way velocities are inherently conventional to some extent. This necessarily includes the one-way speed of light.
The relativistic nature of spacetime can be “pushed” conceptually from one place to another, but it cannot be eliminated. Your comment that using ASC “the imagined speed of light depends on its direction where the observer is” illustrates this – because the same type of thing is true of velocities under ESC. Under ESC observer A sees light moving at speed c relative to himself, and observer B sees light moving at speed c relative to herself, even if A and B are moving relative to each other! Moreover, if observer A accelerates, he will perceive that the light adjusts so that it is still speed c faster than himself. Under either convention the light seems to “know” what the observer is doing and instantly adjusts itself relative to any given observer. Like it or not, that’s the way the universe is.

“Simple stellar aberration diagram” by BlankAxolotl – inkscape. Licensed under CC BY-SA 3.0 via Wikipedia
The aberration of starlight (also called stellar aberration) is an astronomical phenomenon which produces an apparent motion of stars about their locations dependent on the velocity of the observer. Aberration causes objects to appear to be angled or tilted towards the direction of motion of the observer compared to when the observer is stationary. The change in angle is very small, and specified by the ratio of v/c where c is the canonical speed of light and v the velocity of the observer. With annual stellar aberration, the apparent change in the position of a star varies as observed by an Earth observer periodically over a year as the Earth’s velocity changes as it revolves around the Sun, with a maximum angle of about 20 arc-seconds in right ascension or declination. It traces a small ellipse on the sky over that time.
The fact of stellar aberration, which has been explained by a constant speed of light c, has been used by some to “refute” the idea of an infinite one-way speed of light in Lisle’s ASC model. The claim is that aberration would not occur at all if the one-way incoming speed of light was infinite, thus v/c = 0, here. Dr Jason Lisle responds to this claim.
