How does a biblical creationist explain the fact that we see the sun?

Figure 1: The sun is 150 million km from Earth.

Genesis chapter 1 tells us that God created the sun on the 4th Day of Creation week and the chronology of the Bible puts that about 6 thousand years ago.

The sun is at a distance of about 150 million km and that means light travelling at about 300,000 km/s would take about 8.3 minutes to travel from the surface–the photosphere–to Earth.

But doesn’t the very existence of the sun present a problem for biblical creation? The idea is that the sun is no more than 6 thousand years old. Then how does light reach Earth in that short period of time?

No problem you say! It only takes 8.3 minutes to get to Earth so it easily fits into the 24-hour period of the Creation Day 4. And certainly into the 6 thousand years that have passed since Creation. You say there is no problem there.

In relation to the stars and galaxies, millions and billions of light-years distant, it is admitted by biblical creationists that there is a problem–a starlight travel-time problem–which some have suggested potential solutions for.

My current view is that the ASC model is by far the simplest solution to that problem (see list below). Continue reading

The effects of the Curse visible in the cosmos present another biblical creationist starlight travel-time problem

Abstract: The notion that the Curse was applied to the whole universe creates another light travel-time problem for biblical creation. Even if we assume that God supernaturally instantly cursed all parts of the universe how do we see those effects now? Any biblical creation cosmology that assumes the ASC is the language of the Bible, which includes an infinite one-way speed of light to the observer on Earth, has an answer to this question. Yet, any cosmology that assumes the ESC is the language of the Bible, which includes the speed of light limited to c (approximately 300,000 km/s), appears to not be able to answer the question. This alone would appear to rule out all cosmologies that rely of the ESC as the language on the Bible.


The Curse is an event that many Bible reading Christians know something about. We read in Genesis 3:14-17 that God cursed the earth after Adam and Eve sinned against Him by eating of the tree which He commanded them not to eat of. Their sin brought on them the serious consequence of death. God also cursed the creation, bringing about various forms of corruption, which resulted in life being much more difficult for Adam and Eve and the rest of all life on Earth. The Scriptures tell us that God cursed the whole creation—the whole universe. We may conclude this from Romans 5:12:

“Therefore, just as sin came into the world [Greek kosmos] through one man, and death through sin, and so death spread to all men  because all sinned” (ESV, emphasis added)

The Greek word kosmos meaning ‘orderly arrangement’is translated ‘the world’ in this verse, but meaning the whole universe. (Incidentally, it is the word from which we drive our English word ‘cosmos’.) Thus it was not only humans that were cursed but the whole universe. This is standard biblical creationist doctrine. This conclusion is strengthened when we read Romans 8:19-23:

“For the creation [Greek ktisis] waits with eager longing for the revealing of the sons of God. 20 For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope 21 that the creation itself will be set free from its bondage to corruption and obtain the freedom of the glory of the children of God. 22 For we know that the whole creation has been groaning together in the pains of childbirth until now. 23 And not only the creation, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption as sons, the redemption of our bodies.” (ESV, emphases added)

In this passage the Greek word ktisis meaning ‘original formation’ is translated as ‘the creation’. From the context it has the meaning of the entire creation—animate and inanimate—with the exception of two sets of beings. From verse 23 we can conclude that the creation here does not include the saved children of God. Also it would not include the unbelieving humans as they are not eagerly waiting for the adoption as sons of God. It also cannot include the angels, because the good angels are not subject to futility and therefore the Curse. The bad angels ‘fell’ sometime before the Curse itself and many are kept in chains in prison (2 Peter 2:4) until the final judgement.  So the meaning is all other living creatures and all the physical universe.

Einstein’s physics says there is no biblical creationist starlight travel-time problem

Review of the book “The Physics of Einstein” by Jason Lisle


I would say that there is no other biblical creationist book like this on the physics of Einstein. Astrophysicist Jason Lisle explains the subject matter in a style that any educated non-specialist could understand. However, there are sections that contain equations, which are important, but they are sectioned off into boxes so that one may skip those without loss of the train of thought.

In the book Lisle addresses questions such as:

“Is it possible to travel faster than the speed of light? Will future human beings build spaceships that can travel at ‘warp’ speed like in Star Trek? Is time travel possible? If so, could we ever travel back in time to prevent a catastrophe from occurring? What does E = mc2 really mean? What are black holes, and do they really exist? What would happen to a person who fell into a black hole, and how do we know? Is the universe really expanding? How long does it take starlight to travel from distant galaxies to Earth? Does this distant starlight require the universe to be billions of years old?” (p.7)

Figure 1: The Physics of Einstein

The book starts with a short history of Einstein and his discoveries in physics. Though Einstein never performed any physical experiments to test his theory of relativity, today it is one of the most well established theories of science.

One small initial criticism I would make is how Lisle uses the word ‘prove’ in relation to relativity theory. He does qualify what he means:

“My point here is that relativity, unlike most branches of science, is actually provable, within the context of its foundational premises” (p.9)

I think it is unfortunate that he was not clear enough on this. He writes that the proofs involve basic logic, basic geometry and basic mathematics. This is a different sense to experimentally testing a theory. In an experimental sense no theory can ever be proved. It can be tested and even disproven, but never proven. Even so, relativity—both the special and general theories—has been extensively tested on Earth and in space and has be found to be exquisitely consistent with all results.  Nevertheless, there is a domain where it is expected to break down, and that is at the quantum level.

Newton and Maxwell

Chapter 1 starts out with a discussion of Newtonian physics, involving gravitation as well as the three laws of motion. Newton realised that all motion is relative, that is, that any speed and direction of a particle is only meaningful when quoted with respect to a particular observer. And this sets the scene for the rest of the book. One important aspect of that is ‘reference frames’. The outcome of any experiment will always be the same for all inertial reference frames, though the measured values may vary. An inertial reference frame is one where the observer is not accelerating—but either stationary or moving in a straight line. So Newton’s laws of motion apply only to inertial reference frames. The Earth is not an inertial reference frame but for some applications it is approximated as such.

Can we see into the past?

Is it possible that when we look into the cosmos that we are seeing into the past?

Hubble Deep Field showing galaxies up to 10 billion light-years distant from Earth.

We hear all the time that we are looking into the past when we look out into space. But we can’t definitively say that! In the following I’ll explain why.

Astronomers say that because the speed of light is a finite value (c = 299,792.458 km/s ) it takes light 1 year to travel a distance of 1 light-year. On the surface of it that seems very reasonable.

That means that light leaving the star alpha Centauri, which is 4.3 light-years away, took 4.3 years to get to Earth and thus the information in that light is 4.3 years old by the time it gets to Earth. Thus they say we are looking back in time — into the past. And for distant galaxies this means we are looking back in time even billions of years.

But is that correct? Continue reading

New cosmologies converge on the ASC model

— a review of two cosmology papers presented at the International Conference on Creationism in 2018  (to be published in Journal of Creation)


In 2001 Jason Lisle (under the pen name Robert Newton) introduced the idea of Anisotropic Synchrony Convention (ASC) into the discussion amongst biblical creationists to solve the starlight travel-time problem.1 The ASC is a convention on clock synchronisation, or put another way, the conventionality of the simultaneity of distant events in spacetime.

This topic is relevant to the discussion of the creation of the stars in the universe on Day 4 of Creation week 6 thousand years ago. The ASC posits that an event occurs when an Earth observer sees, or could have seen, the event happen. And Lisle proposed that the ASC is the language used in the Bible. As such it leads to the initial simultaneous2 creation of all stars in the universe on Day 4, where, in principle, the event is timestamped3 as occurring when the starlight from all stars arrived on Earth for the first time. This means there is no light travel-time problem because the events were seen to occur (on Earth) simultaneously (or at least, within the period of one Earth day, that is, on Day 4). Therefore, there is no light travel-time problem.

In 2010 Lisle strengthened his original arguments with a discussion of the past light cone and Special Relativity.4 In that paper he introduced the ASC model, a model that uses the ASC. And his ASC model makes testable predictions.5

Lisle also carried further the notion of the one-way speed of light. Since the one-way speed of light cannot be measured it really has no physical meaning in the universe.6 Thus there is a free choice. And by Lisle’s choice of the ASC it follows that the incoming speed of light is infinite, and thus the outgoing speed must be ½ c (where c ≡ 299 792 458 m/s is the canonical isotropic—i.e. two-way—speed of light that we are very familiar with).7

Many people, biblical creationists included, have expressed disbelief, concern, and other emotions over the concept of the one-way speed of light being any different from the usually assumed isotropic speed c. Nevertheless it is important to note that concepts around the one-way speed of light are based on real physics.

The choice of a timing convention in no way affects any underlying physics. The physics is always the same no matter what convention one may choose.8 Einstein chose a value of the clock synchronisation parameter, known as the Reichenbach synchronization parameter (ε), in his equations for Special Relativity that defines the one-way speed of light as being equal to the two-way speed.9 Any value for the parameter ε between 0 and 1 may be chosen. Nature itself does not choose, nor impose any requirement on its value within this domain. The parameter represents our free choice of a timing convention. Hence we are free to choose any value of the Reichenbach synchronisation parameter ε, provided it is between 0 and 1. Einstein chose ε = ½ (ESC) and Lisle chose ε = 1 (ASC). Choosing a value for this parameter is in no way dissimilar to a choice of a different coordinate system. And regardless of which coordinate system one may choose the underlying physics is unaffected. What is different is only how we represent the physics in the different coordinate system. The equations of motion may be more complex in one coordinate system than in another but in all cases the physics is unaffected.10

Thus no amount of appealing to Maxwell’s equations (derived pre-Einstein)11 or any other well-known physics can refute the notion of free choice for the one-way speed of light, or more precisely, the conventionality thesis of distant simultaneity. Continue reading

Has light from the first stars after the big bang been detected?

“Astronomers detect light from the Universe’s first stars” is the headline of a Nature news article, which appeared February 28, 2018.1  It relates to observations made by a team of astronomers led by Judd Bowman of Arizona State University in Tempe. The team published their results in Nature the same week.2 According to Bowman,

“This is the first time we’ve seen any signal from this early in the Universe, aside from the afterglow of the Big Bang.”

They used a small radio-telescope situated in the Western Australian desert, far away from human settlement to minimise interference from radio signals generated by human technology. (See Fig. 1.) The antenna was tuned to a waveband of about 78 MHz, which is at the low end of FM radio, so isolation from human generated radio signals was essential.

To understand what the astronomers interpret from this research I quote an editorial summary from Nature:3

“As the first stars heated hydrogen in the early Universe, the 21-cm hyperfine line—an astronomical standard that represents the spin-flip transition in the ground state of atomic hydrogen—was altered, causing the hydrogen gas to absorb photons from the microwave background. This should produce an observable absorption signal at frequencies of less than 200 megahertz (MHz). Judd Bowman and colleagues report the observation of an absorption profile centred at a frequency of 78 MHz that is about 19 MHz wide and 0.5 kelvin deep. The profile is generally in line with expectations, although it is deeper than predicted. An accompanying paper by Rennan Barkana suggests that baryons were interacting with cold dark-matter particles in the early Universe, cooling the gas more than had been expected.”

Let’s look at this in two stages. What was observed and what is the interpretation of the recorded data. Continue reading

Cosmology’s fatal weakness—underdetermination

Can we definitively know the global structure of spacetime? This is a good question. It is one that is actively discussed in the area of the philosophy of modern physics.1,2

However it is a question that highlights the fundamental weakness of cosmology and hence of cosmogony. (Cosmology is the study of the structure of the cosmos whereas cosmogony is the study of the origin of the universe.)  That weakness is the inherent inability to accurately construct any global cosmological model, i.e. a model that accurately represents the structure of the universe at all times and locations. The reason for this is underdetermination.3

“There seems to be a robust sense in which the global structure of every cosmological model is underdetermined.”1

In the philosophy of science, underdetermination means that the available evidence is insufficient to be able to determine which belief one should hold about that evidence. That means that no matter what cosmological model one might conceive of, in an attempt to describe the structure of the universe, every model will be underdetermined. Or said another way, no matter what amount of observational data one might ever (even in principle) gather, the cosmological evidence does not force one particular model upon us. And this underdetermination has been rigorously proven.1 Continue reading
