ADVANCE IN TIME-KEEPING CLOCKS UP EUREKA WIN 

Technology using a pure sapphire crystal to accurately measure time has taken out the 2018 Defence Science and Technology (DST) Eureka Prize for Outstanding Science in Safeguarding Australia.

Minister for Defence, the Hon Christopher Pyne MP, today congratulated Professor Andre Luiten and his team from the University of Adelaide on developing the sapphire clock, a device so accurate it can keep time within one second over tens of millions of years.

The sapphire clock team is working closely with Defence scientists to use the technology for upgrades and enhancements to the Jindalee Operational Radar Network (JORN).

The sapphire clock has the potential to produce the purest of signals which, when fed into JORN, could generate high quality surveillance data.

“This innovation delivers a step change in radar frequency, purity and overall performance over conventional devices giving Defence a significant capability edge,” Minister Pyne said.

“This is an example of world-leading research with a positive impact on Australia’s defence and national security.

“It is a fantastic result which will be a game-changer for Defence capability.”

The DST Eureka Prize for Outstanding Science in Safeguarding Australia is awarded annually for outstanding science or technology that has developed, or has potential to develop, innovative solutions for Australia’s defence or national security.

No CMB shadows: an argument against the big bang that can no longer be sustained

I have previously made the argument that the cosmic microwave background (CMB) radiation, ‘light’ allegedly from the big bang fireball, casts no shadows in the foreground of galaxy clusters.1 If the big bang were true, the light from the fireball should cast a shadow in the foreground of all galaxy clusters. This is because the source of the CMB radiation, in standard big bang cosmology, is what is known as the “last scattering surface“.

The last scattering surface is the stage of the big bang fireball that describes the situation when big bang photons cooled to about 1100 K. At that stage of the story those photons separated from the plasma that had previously kept them bound. Then expansion of the universe is alleged to have further cooled those photons to about 3 K, which brings them into the microwave band. Thus if these CMB photons cast no shadows in front of all galaxy clusters it spells bad news for the big bang hypothesis.

The CMB radiation shadowing effect, or more precisely the cooling effect, by galaxy clusters is understood in terms of the Sunyaev–Zel’dovich Effect (SZE). This is where microwave photons are isotropically scattered by electrons in the hot inter-cluster medium (ICM) (see Fig. 1) via an inverse Compton process leaving a net decrement (or cooling) in the foreground towards the observer in the solar system. Of those CMB photons coming from behind the galaxy cluster less emerge with the same trajectory due to the scattering. Even though the scattered photons pick up energy from the ICM the number of more energetic CMB photons is reduced. After modelling what this new CMB photon energy (hence temperature) should be, a decrement can, in principle, be detected.

Starting around 2003 some published investigations, using this SZE, looked for the expected shadowing/cooling effect in galaxy clusters. No significant cooling effect was found, by multiple studies, including the WMAP satellite data.2 This was considered to be very anomalous, significantly different from what was expected if the CMB radiation was from the big bang fireball. The anomaly was even confirmed by the early Planck satellite survey data in 2011.3

Let There Be Light

by Jim Gibson

“In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.” (Genesis 1:1-5)

As someone once said, “the first four words of the Bible are some of the most sublime words ever written.” In fact, that first creation day contains mysteries that the mind of man will never be able to comprehend. In this feeble attempt, I want to highlight just a few of these unfathomable secrets. This is not a scientific paper as such, rather, it is theological which contains inherent scientific concepts. Obviously, what I will present to the reader are just my own beliefs and thoughts regarding some of the mysteries involved in God’s creation of light.

In the beginning. This phrase denotes the element of time. Thus, it speaks to the origin of time itself. As a biblical creationist, I accept the fact that God as Creator exists outside the boundaries of time and His own creation. Here, in this verse, it alludes to the idea that God created time. To have time, matter must exist.

This verse has become a gateway for a controversy that exists within Christianity today. Many Christians support the idea that God used the vehicle of evolution to bring about His creation. Those that do so also embrace cosmic evolution. Cosmic evolution accepts the alleged Big Bang and the belief that our universe “evolved” over a period of billions of years. If one were to take the plain meaning of Jesus’ words, then they would discover that Jesus did not share this view. In fact, his words denounce such an inference. We find in scripture that Jesus placed the creation of man at the very beginning of creation. There is not a gap or billions of years found within the Creation Week. If Jesus were to address the Church today regarding this issue, I believe He might begin with these words, “Have ye not read.” The Jews of Jesus’ day knew exactly His point of reference when He used the word “beginning” in the passages below.

“…Have ye not read, that he which made them at the beginning made them male and female.” (Matthew 19:4)

“But from the beginning of the creation God made them male and female.” (Mark 10:6)

God created. God is the “First Cause.” He is transcendent of His creation, that is, God exists apart from and not subject to that which He created. To the secular scientist, this is incomprehensible. The Hebrew word “bara” is here translated created. The Latin phrase for this word is ex nihilo, which essentially means, “out of nothing.” As others have pointed out, this word is only used in the context with God, never man. Contrary to secular science, and the supposed Big Bang, there really was nothing. There were no quanta (energy particles) or matter. What an awesome God we serve! True are the words of the writer of the book of Hebrews, “For the word of God is quick (living), and powerful…” Yes, He spoke, and matter began to exist as did time.

The heaven and the earth. Many Hebrew scholars say that the phrase, heaven and earth, is a merism. A merism is a term which means that two contrasting words denote the entirety or totality of a thing. The example given for it in a dictionary is, “I searched high and low.” In other words, he searched everywhere. So, in this first verse, the Bible declares that God created all matter which He would use to form the universe. Continue reading →

Book review: “An Appeal to Reason” by Jim Gibson

“An Appeal to Reason” is subtitled “Examining the evidence of origins in the evolution verses creation debate”. The author, Jim Gibson, employs a witty and, in some cases, sarcastic style. He intends the book to appeal to the younger generation, who have little knowledge of the facts surrounding the story that is now taught universally in the education system of the origin of life on this planet. Evolution is marketed as a fact—as the true history of life on Earth. The author points to many scientific discoveries that contradict that story. Published by Tate Publishing, Oklahoma, USA (2014) and available from Amazon.com.

The book is wide-ranging in its subject matter, yet does not load the reader with too many or superfluous details, yet provides sufficient explanation to show that the biblical creation model of understanding the history of the universe and life on Earth is a far better explanation than that offered by the evolution story.

Jim Gibson’s approach to the subject is different to the approach I have read in many other creationist publications that deal with similar material. It is fresh, insightful and challenging to anyone willing to open their mind and use commonsense and reason in understanding the evidence—both present day observations and accounts from history as recorded by scientific observers over the past few hundred years. Therefore I recommend it to everyone.

See video promo from Tate Publishing. But note the book is no longer available at Tate Publishing. See update below. Continue reading →

Book Review: “Setting Aside All Authority” by Christopher M. Graney

The book “Setting Aside All Authority” comprises 10 chapters, 270 pages. The last half of the book is largely made up of two appendices: (A) the first English translation of Monsignor Francesco Ingoli’s essay to Galileo (disputing the Copernican system on the eve of the Inquisition’s condemnation of it in 1616) and (B) excerpts from the Italian Jesuit astronomer Giovanni Battista Riccioli’s reports on his experiments with falling bodies. The book is published by the University of Notre Dame, 2015.

Cover of the book. The cover image is taken from Riccioli’s New Almagest (1651). Note the heliocentric system (top left) compared to the Tychonic hybrid geocentric system (bottom right).

The main thesis of the book challenges the notion that around the time of Galileo, and the beginning of the Copernican revolution, opponents of the heliocentric worldview, championed by Galileo, were primarily motivated by religion or dictates from the authority of the Roman Catholic Church.

The author, Christopher M. Graney, uses newly translated works by anti-Copernican writers of the time to demonstrate that they predominantly used scientific arguments and not religion in their opposition to the Copernican system. Graney argues that it was largely a science-versus-science debate, rather than church authority-versus-science as often incorrectly portrayed.

In the 1651, the Jesuit Giovanni Battista Riccioli published his book the New Almagest wherein he outlined 77 arguments against the Copernican system (pro-geocentrism) and 49 arguments in favour of it. Most arguments against the Copernican heliocentric system could be answered, at that time, but Riccioli, using the then available telescopic observations of the size of stars, was able to construct a powerful scientific argument that the pro-Copernican astronomers could not answer without an appeal to the greatness of God.

Graney largely uses Riccioli’s New Almagest, which argues in favour not of the Ptolemaic system but of the hybrid Tychonic system, where the Earth is immobile at the centre of the universe, the sun, the moon and the stars circle the earth; but the planets circle the sun. Riccioli built on the work of the Danish astronomer Tycho Brahe, and built a strong scientific case against the heliocentric system, at least through the middle of the seventeenth century, which was several decades after the advent of the telescope.

The main two arguments presented in the book, both scientific, are the size of stars and the effect on falling bodies.

Falling bodies

If the earth were rotating, then a falling body should hit a point on the surface of the earth at a definite distance from a vertical line to the surface, if dropped vertically. The same argument could be made for cannon balls fired in different directions on the earth’s surface. These type of discussions and arguments carried on for a century, and even Isaac Newton got involved. What we now know as the Coriolis force, a ‘fictitious’ force, resulting from the rotation of the planet on the fired or dropped objects could not be measured with the required precision in the 17th century.

The Big Picture: On the Origins of Life, Meaning and the Universe Itself? Part 10

Part 10 of my review of the book: “The Big Picture: On the Origins of Life, Meaning and the Universe Itself,” by Sean M. Carroll. Part 9 is found here.

Consciousness

The fifth of the six section divisions of the book is titled “Thinking,” which includes chapters on the origin of consciousness. This section is very vague, perhaps because there is a major lack of any real experimental evidence in support of what gives rise to consciousness and therefore any evolutionary speculations on how it arose in a Darwinian world are very tenuous.

Carroll opens the first chapter in this section “Crawling into Consciousness” with:

“Almost 400 million years ago, a plucky little fish climbed onto land and decided to hang out rather than returning into the sea. Its descendants evolved into the species Tiktaalik roseae, fossils of which were first discovered in 2004 in the Canadian Arctic.” (p.317)

Only the second part of the second sentence has any factual basis in being a true statement. The rest here, though stated as a fact, is completely assumed—made up—just pulled out of the air. There is no evidence—fossil or otherwise—of a fish that climbed onto land and decided to stay there.

“If you were ever looking for a missing link between two major evolutionary stages, Tiktaalik is it; these adorable creatures represent a transitional form between water-based and land-based animal life.” (p.317, emphasis added)

On the same page he shows a reconstruction of a Tiktaalik roseae fish half in and half out of the water. See Fig. 1.

The animal was more likely a fish with some mosaic like features in the same way that Archaeopteryx, a bird, had teeth and claws on its wings, resulting in claims that it was also a transitional form.1 But note Tiktaalik roseae, could not walk.2 Tiktaalik’s fin was not connected to its main skeleton, so it could not have supported its weight on land. Thus the story of it coming out of the water and walking on land is pure fiction.

Then Carroll continues with his storytelling about how a fish evolved while climbing onto land. He uses expressions like “We don’t know, but we can make some reasonable guesses.” (p.318) He then argues that the evolutionary pressure on the fish as it swims under water and its need to think quickly caused its brain to evolve to think more quickly. “A fish brain is going to be optimized to do just that.” (p.318) But this is just another statement of faith—faith in an unobserved process, based on a belief that evolution happened over billions of years.

“Bioengineer Malcolm MacIver has suggested that the flapping of fish up onto dry land was one of several crucial transitions that led to the development of the thing we now call consciousness.” (p.319)

The Big Picture: On the Origins of Life, Meaning and the Universe Itself? Part 8

Part 8 of my review of the book: “The Big Picture: On the Origins of Life, Meaning and the Universe Itself,” by Sean M. Carroll. Part 7 is found here.

Darwinian Evolution

In his next chapter “Evolution’s Bootstraps” Carroll starts by describing Richard Lenski’s experiment, which he labels as evolutionary biology. I am thinking that Carroll must have gotten the creationist message that evolution (in the goo-to-you sense) cannot be science because there is not one experimental demonstration of any process which changes microbes into molecular biologists. I say this because he states:

“Evolution is the idea that provides the bridge from abiogenesis to the grand pageant of life on Earth today. There is no question that it’s a science: evolutionary biologists formulate hypotheses, define likelihoods of different outcomes under competing hypotheses, and collect data to update our credences in those hypotheses.” (p.273, emphasis added)

In the first sentence he uses one definition for the word ‘evolution’ (the bridge from abiogenesis to the grand pageant of life) but in the following sentence it is different (mutations and selection though not explicitly stated). After the word ‘science’ what follows implies ‘evolution’ is observable in the lab, by carrying out experimental science. This is changing of the definition is called equivocation, and demonstrates very poor logic.

Very strangely Carroll does not see the point he makes himself in terms of the weakness of equivocating on the meaning of the word evolution when he admits that chemists and physicists have an advantage over evolutionary biologists because they can perform repeated experiments in their labs. The latter defines experimental science but nowhere in his statement (above) does he indicate that the evolutionary biologist carries out an experiment that “provides the bridge from abiogenesis to the grand pageant of life”.

The data collecting and formulating of hypotheses is in relation to what they believe happened in the past. At best this is historical science, a type of forensic science that tries to unravel the sequence of unseen past events. But experimental science or operational science, which is the usual definition used for science, depends on repeatable experiments to test hypotheses. This the evolutionary biologist cannot do and he admits it.

“It would be very hard to set up a laboratory experiment to see Darwinian evolution in action, just as it would be hard to create a new universe.” (p.273) (emphasis added)

Nearly correct, but not quite! It would be not “hard” but impossible. But like all evolutionists, he then equivocates at this point saying:

“But it’s not impossible. (At least for evolution: we still don’t know how to create new universes.)” (p.273)
