Synopsis: A biblical creationist cosmogony (Japanese translation)

The starlight-travel-time problem has been a difficult issue for biblical creationists for a long time. Big Bang cosmologists also have their own starlight-travel-time problem but creationists have proposed various solutions to this problem in the past decade or more. Recently I proposed an expansion on a solution, first proposed by Jason Lisle, in an article entitled “A biblical creationist cosmogony.” It is somewhat technical so I thought I’d write a very short layman summary here.

星の光が届く時間の問題は、聖書的創造論者にとって長い間難題でした。ビッグバン宇宙論者にとってもやはり星の光が届く時間は難題となっています。しかし創造論者は、過去数十年にわたって、この難題に対する答をいく通りか提案してきました。近年私が提案しているのは、最初にジェーソン・ライルが提案した論文「聖書的創造論者の宇宙論」を発展させたものです。これは多少専門的なので、一般向けにこれを説明しようと考えました。

創造主が、創世記1章に記されている順序通りにご自身がすべてを創造したなら、そこに記されているすべての出来事は、その示す通りに約6000年前に24時間を1日とする連続した6日間で起こったはずです。ライルは、これらの出来事(星の創造)は光が最初に地球に到達した時点、あるいは、仮に地上に観測者がいた場合にその観測者が光を最初に目にした時点で起こったと提案しました。その要点は、星や銀河の創造で、ある光は100億光年以上もの距離から到達したというものです。もし私たちが観測者の視点(どう見えるか)のみを考慮するなら、これらの銀河やすべての星の光が最初に届いたのは、創造の第4日のどこかの時点です。

もし、光の速度は一定(c)であるという視点からこれを見れば、光は1年で1光年の距離を進むので、遠い星の光は100億年以上もかけて地球に到達したということになります。したがって、この視点から宇宙を考えるなら、すべての銀河は創造主が創造の第1日に地球を創造するはるか前に造られたということになります。しかし、これも単に観測者の視点(どう見えるか)の問題なのです。「光の速度は一定(c)である」という仮定は、(始点と終点にある)複数の時計の時刻が一致していることを想定しています。私たちは同様に、これとは別の想定、すべての出来事は観測者が目撃した時点で起こったとする想定を選ぶことができるのです。そうすると、「新しく」造られた星々や銀河の光が、創造の第4日に地球に到達したのです。それは、本当にこれらの銀河が造られた時に発せられた最初の光です。

Does the new much-faster-speed-of-light theory fix the big bang’s problems?

A recent paper1 by Niayesh Afshordi and João Magueijo asserts that they have discovered a testable cosmology wherein during a “critical” cosmological phase of the early universe the maximal speed of propagation of matter (and hence light) was enormously much faster than the current speed of light (c) and faster than the speed of gravity, which in Einstein’s theory is the canonical speed c. They revisit what has become to be known as varying speed of light (VSL) models, in contrast to the now popular cosmic inflation models. They believe light travelled much faster just after the big bang than it does now and have developed a mathematical model of a big bang universe only a miniscule fraction of a second after the alleged hot beginning of the Universe.

The big bang model has many problems, but the biggest and most difficult to solve is what is known as the ‘horizon problem’.2 Cosmic inflation has been invoked to solve this problem. Afshordi and Magueijo agree that,

… the Big Bang model of the Universe remains an unfinished work of art. Many of its late-time successes can be traced to the initial conditions postulated for its early stages, and these are put in by hand, without justification, other than to retrofit the data. The main culprit for this shortcoming is the so-called horizon problem: the cosmological structures we observe today span scales that lay outside the ever-shrinking “horizons” of physical contact that plagued the early universe. This precludes a causal explanation for their initial conditions.1 (emphases added)

Cosmologist believe that structure in the universe was seeded from initial density variations in the early universe. But for structures (clusters of galaxies, for example) to naturalistically form gravity must propagate over the scale of any structure in the timescale available to it at the past epoch when the structures were allegedly built. In addition we observe a uniform temperature across all the sky in the cosmic microwave background (CMB) radiation, yet sources on opposite sides of the observable universe have not had time to exchange energy, at the constant speed of light c, in the time available in the big bang universe. That is, they have not had to time to come into thermal equilibrium. These limitations are what are known as ‘horizons’. The major problem with the big bang model is that cosmic inflation scenarios are inserted by hand, to overcome these ‘horizons’ but without any justification for why inflation started and why it stopped. Quite obviously if the speed of light were infinite there would exist no such ‘horizon’ to thermal equilibration of the Universe.

Questions on the ASC model

The following I received in an email in relation to the ASC model. The ASC model, I believe, answers the biblical creationist starlight-travel-time problem. Actually it eliminates it, because there is no light-travel problem, of any sort, in that biblical cosmogony. I do agree though that people not familiar with ideas of relativity and the speed of light measurement may have confusion or misunderstandings on this topic. The writer’s words are in blue text and my responses in grey.

Hello.  I appreciate greatly your ongoing contribution to the creation-science cause.  However, I find I just don’t get ASC. I’m sure the following will expose a misunderstanding, but when you suggest ideas like celestial events being ”time-stamped” only when seen on Earth, that comes across as if God really created the stars earlier than Day 4, but their light was only visible on Earth on Day 4.  ASC also sounds to me like it’s not describing actual reality, but only appearances. Thus it seems (again, to my confused perspective) that straightforward biblical statements about actual celestial events are not trustworthy.

Firstly let me define ASC model. It is the biblical creation model where the Anisotropic Synchrony Convention (ASC) is assumed as the clock synchrony convention for timing all events. The ASC model was developed by Jason Lisle (references below) and I have developed my own model as an extension of his using the exact same ASC convention.

If starlight travel is to fit within 6 Earth-days, then it confuses me even further when you say that the ASC model doesn’t require time dilation.

I suspect you may tell me that my reasoning “assumes the ESC model,” as I’ve read you telling several others.  In case you would say the same to me, I don’t see how that could be the case, since I’d never heard of the ESC before an hour ago.  No, my only assumption here is that Genesis statements about celestial events are statements about actual reality, not mere “time-stamps.”  I don’t see how the ASC model can be squared with Exodus 20:11.

Quite obviously not having heard the term, or even the reason, for something does not exclude the use of it from our experience as it could be something we have been taught all our lives but never known what it was called. Does the average person, who keeps their food cool in a refrigerator, actually know why it preserves food better than being left in a room temperature box? And does the average person even know the term ‘thermodynamics’ and how it works? Have they ever heard of ‘Gibbs free energy’ without which the fridge couldn’t do any ‘work’? Do they even know that refrigerators do ‘work’? Ignorance is not necessarily a valid argument.

Just never having heard the expression “Einstein Synchrony Convention (or ESC)” does not mean that a person doesn’t automatically assume it when thinking about an event connected to the reception of a light signal.

When the light from this massive solar flare left the sun we had our eyes closed but when we opened them, 8.3 minutes later, the light entered our eyes and we saw it at the moment of the eruption.”

Mature creation and false information in starlight

Some biblical creationists argue for a mature creation as an explanation for the history of Genesis to align with modern cosmological observations. Don DeYoung1 is one who argues that such a view is not refutable, and he is quite right. But neither is any cosmology as really cosmology is not science.2 It is not subject to repeatable laboratory type tests that is normally required in science. Its goal is to reconstruct the history of the Universe, and in so doing cosmology is more akin to evolutionary biology or geology in which researchers must simply accept some facts as given. That makes cosmology more like a religion, a belief system, with its unprovable axioms upon which everything else is based.

De Young argues that all biblical creationist cosmogonies (i.e. worldviews) contain some level of mature creation, which I do agree with. The problem, though, which he does not address, is the issue of false information in starlight.

We know that the Universe is very large. Light travels very fast indeed, yet light travelling at its measured speed travels one light-year distance in one year (by definition). The Bible tells us that the Universe is only about 6000 years old, but the distances light needs to travel from the most distant sources to Earth, since creation, is about 14 billion light-years. So DeYoung, and others like him, claim that God created the ‘light in transit’. He says that this explanation is valid as it is equivalent to the mature creation of our sun or even to adult forms of life created on Earth (i.e. Adam and Eve created in the Garden as adults and not babies or embryos). On some level this may be true, but the ‘light in transit’ remains a problem in terms of God’s truthfulness.

No doubt DeYoung, and those others who hold similar views, believe that God is 100% truthful, yet they see no problem with false information in the ‘light in transit’. DeYoung excuses it by saying that it is nevertheless true in the mind of God. But there still remains a problem.

In Psalm 91 (and other passages in the Bible) we are told that the heavens tell us of God’s workmanship. Is this also only in the mind of God? Is everything that is in the astrophysical heavens just part of a big light show, which has no reality, such as the reality we can discover with the rest of our senses here on Earth? I don’t think so.

So how do you justify ‘light in transit,’ which does not relate back to real events in the past history of this Universe? If you want to take the approach of the least number of assumptions, that is, using Occam’s Razor,3 a law of economy, then I would say that a time-dilation model or a time-convention model is a far simpler and better choice.4 For example, I could construct a cosmogony (description of the origin of the Universe) where our Creator God makes the sun, the moon, the planets and all the stars and galaxies on Day 4 of Creation Week, according to Genesis 1.5 But in so doing He slows the rate of clocks on Earth during that day only. Really that means he slows the rate at which time passes on Earth relative to elsewhere in the cosmos. He makes some galaxies initially and places them throughout the Universe, like unfurling a flag or tent. It does not necessarily involve any stretching of the fabric of space, or of time or of space-time. This Universe is not an expanding, but created static, with the galaxies essentially in the same locations now as when they were created 6000 years ago, as measured by Earth clocks.

Israel Trip 2016: Biblical creation lectures

On Saturday 4th June we returned from our 2½ week tour of Israel where my wife, Christina and I teamed up with 14 others from Australia, USA, NZ, Japan and Finland. The trip combined a biblical creation ministry with a 10 day tour of the sites around Israel, with a focus of relevant Bible history and creation science teaching. Our tour guide was a professional archeologist and Christian. The tour was sponsored by a Finish Christian outreach ministry. We were also supported by Israeli Messianic congregations and an Israeli Messianic conference ministry.

Biblical creation lectures, “8 Reasons Why Evolution is Foolish” (JGH), “The Heavens Declare…” (JGH), “Evidence for a Young Universe” (RH), “Cosmic Magnets” (RH) and “Flood Geology” (JB), “A Linguistic Argument” (JB) and others were delivered all over the country. They were given at:

  • a student conference (about 40, mostly Arab Christians,18-25 years old)
  • a youth conference (270 Jewish children, between 13-20 years old)
  • about 8 Messianic congregations (Tiberias, Jerusalem, Modi’in, Beer Sheva, Tel Aviv and other cities)
  • Hotel presentations: 3 different talks, in 2 cities
  • Total of 24 talks presented over 12 days by 3 speakers: myself (Dr John Gideon Hartnett), Dr Russ Humphreys and Dr John Baumgardner

The talks were translated into Hebrew and video recorded. Eventually we hope they will be available on YouTube.

For highlights of the guided archeological tour watch this 6 minute video (Powerpoint presentation) Archeological tour. (Sound only in two places)

A letter from a reader

The following is a letter from a reader of Bible Science Forum with my comments in square brackets […].

UniLecture1004May I take the liberty of suggesting that you should be a theologian teaching the simplicity of faith – Christian faith – Belief in The Redeemer – if one believes in the Redeemer, one believes in His Word – that He is the Truth, the Way and the Life – will believe Him when He says that He is the Creator –  believe His account of Creation week.

The entire faith hinges on just Belief – HE is The Redeemer; yet man prefers unbelief or lies.

Scientific concepts:

The sum of all natural numbers 1+2+3+4+…. ∞ =  -1/12
And they prove that by starting with [the series sum] 1-1+1-1….∞ = 1/2. Depending on whether the series is stopped at a positive or a negative number will determine whether the initial answer is 0 or 1; therefore an average of 1/2 is taken as the final answer.
Then they do a few other series of steps and voila — the sum of all natural numbers 1+2+3+4+…. ∞ =  -1/12.

Non-measurability: The one-way speed of light from a star or galaxy –  as a continuous ray or wave from the original that can never be replicated, a one-way speed is not directly measurable and thus physicists assuming uniformitarianism resort to use the ECS (and hence the two-way speed of light) as a convention (as you have so convincingly established).  [See How do we see distant galaxies in a 6000 year old universe?

These are just a few of the assumptions made for each and every scientific theory which people have to accept as far better the Gospel truth. We swallow — hook, line and sinker.

Impact of gravitational wave detection: A Response to Setterfield’s Response

The following is written as a rebuttal to an article titled “In Response to Hartnett’s Article”1, dated February, 2016, written by Mr Barry Setterfield. (This rebuttal is also available on creation.com.) The author states that he received the following email, along with a number of others with the same questions about the Hartnett article:2

I have a question regarding a CMI article by a Dr. John Hartnett entitled “What impact does the detection of gravitational waves have on biblical creation?”  Dr. Hartnett makes the claim that the recent discovery of gravity waves uses a modern value for the speed of light to calculate the masses of the two black holes which collided to produce those waves, so he concludes (a bit too quickly in my opinion) that “the cdk idea is [to be] thoroughly rejected”. I wanted your take on this issue. Here’s the relevant portion of the article:

“Interestingly, the calculation used to determine the masses of the merging black holes in the analysis of this week’s discovery employed the standard canonical speed of light, c. That is, it used the same constant value that we measure today. Does that tell us something? I think it does.

Inspiral of black holes and associated waveform. Ref. 3.

Some biblical creationists favour a much higher value for the speed of light in the past, from a time soon after creation of the universe, after which it decreased or decayed down to its current value (the concept is known as cdk, from c-decay). They use this supposed much higher value of c in the past as a solution of the biblical creationist light-travel time problem. But now this new discovery shows that, at a time in the past representative of a distance in the cosmos of 1.3 billion light-years, the value of the speed of [sic] (c) was identical to today’s current value. Regardless of which creationist cosmology you like, the gravity waves observed in September 2015 must have left their source very soon after Creation week. Thus the cdk idea is thoroughly rejected.”

To which Setterfield responds. So I respond to his response (indented black text) with my comments (blue text) interspersed below his.

Comment on “Issachar Insight – Chuck Missler and Barry Setterfield”

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.

Bsetterfield
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.

What impact does the detection of gravitational waves have on biblical creation?

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 × 1021 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.

A question on the Anisotropic Synchrony Convention

IDL TIFF file
Hubble Ultra-Deep Field Credit: NASA

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.
