Now the expansion of the universe is not accelerating

In 2011 the Nobel Prize in Physics was awarded to three astronomers for their discovery, as part of two separate teams which published their results around 1998 that they claimed showed that the Universe is expanding at an accelerating rate. Also they claimed the existence of some sort of mysterious ‘dark energy’ that was driving the expansion at a faster and faster rate.

The interpretation of the 1998 data depended heavily on the big bang cosmological theory they applied and the assumption that it was the correct theory to describe the structure and time evolution of the Universe. It also depended heavily on the assumption that the type Ia supernova explosions that they used are reliable standard “light bulbs”, i.e. that those stellar explosions all were accurately chosen to have the same characteristic intrinsic absolute brightness.1 The latter, however, we now know is not the case.2

It has been shown that the stellar masses of the stars that result in the type Ia class of supernova are not so well-defined that they all fall within a narrow range as to give a clear standard in terms of the intrinsic brightness of the resulting explosions and hence the type Ia are not a uniform reference. Also as I have previously indicated circular reasoning was employed in the choice of the candidate supernova to be considered.2,3 The cosmology under test was used to choose the candidate Ia supernovae and then those chosen were used to test the same cosmology.

A new study, published in the Nature journal Scientific Reports, on a data set ten times larger than the original studies used (5 years ago) has been carried out.4

Now, a team of scientists led by Professor Subir Sarkar of Oxford University’s Department of Physics has cast doubt on this standard cosmological concept. Making use of a vastly increased data set – a catalogue of 740 Type Ia supernovae, more than ten times the original sample size – the researchers have found that the evidence for acceleration may be flimsier than previously thought, with the data being consistent with a constant rate of expansion.

A cosmic dragonfly

A galaxy, known as Dragonfly 44, first detected in 2015 using the Dragonfly Telephoto Array in New Mexico by Professor Peter van Dokkum is now claimed to be made of 99.99% dark matter.1 It is a galaxy where very few stars can be seen. It took a two-hour exposure using one of the very biggest telescopes on Earth, one of the Gemini telescopes at the W. M. Keck Observatory in Mauna Kea, Hawaii, to get a picture of this wispy galaxy as shown in Fig. 1 below.

Professor van Dokkum from the Astronomy Department and the Physics Department of Yale University is not only an astrophysicist but also a photographer of insects, particularly dragonflies.It is a strange coincidence, or is it, to find that one of his particular interests in the cosmos are these ultradiffuse, or “fluffy” galaxies. One of them is named Dragonfly 44, which van Dokkum and team determined to be at a distance of 300 million light-years from Earth, in the Coma Cluster.3  That distance is easily close enough for a big telescope to see, which can see galaxies at billions of light-year distances but no one had previously noticed these fluffy galaxies before even though they are ‘so close’.

Dragonfly 44 was like “a dirty smudge on a photo of deep space.”1 And it was one of the largest and brightest galaxies of those they found. From its distance its size was determined and it was concluded that it is as big as our Milky Way galaxy, yet it only emits about 1 percent as much light. So I suppose to van Dokkum the galaxy is reminiscent of the very fragile, lightweight and transparent wings of dragonflies he likes to photograph. Continue reading

Does Dark Matter matter?

Cosmology and astrophysics nowadays is dominated by the need for the inclusion of Dark Matter at every scale, from galaxy size, to cluster size, to super-cluster size, to the size of the whole Universe. It is needed at every scale size to get the physics to agree with the observational data. After 50 years of looking in local laboratory experiments there has not been a single trace of it found anywhere. And it would not be overstating the case to say Dark Matter is in serious crisis!

dm-livesThis situation reminds me of a current political trend in America, that is, “Black Lives Matter”, which has turned into a major movement. The proponents of it, describe it as a response to virulent anti-Black racism that they claim permeates the US society.

With that in mind, and in response to a discussion on Dark Matter, a friend sent me this graphic (see Fig. 1), quite obviously as a joke. It is funny but on another level it highlights a problem in the cosmology/ astrophysics society that is not so funny. The problem is that the majority are saying “Dark Matter Lives”. And they are saying that despite the actual experimental evidence to the contrary. In their minds it only “lives” because without it the standard paradigm is “dead”.

Big bang cosmology and the dynamics of galaxies and clusters of galaxies require that “Dark Matter Lives”. Those who voice the obvious fact that Dark Matter is not real, or, should I say, is “dead”, are sidelined or ridiculed. The secular physics community hold that those who express such opinions are expressing a sort of anti-science bias because it ultimately involves a rejection of the big bang paradigm.

Recently the Dark Matter crisis has deepened even more. The admission by a group of theoretical physicists that the physics theory called supersymmetry (SUSY) has been all but disproven by 10 years of experimental searching with the Large Hadron Collider (LHC) has made matter worse.1  That meant one of the last hopes of a dark matter particle was the expected lowest mass supersymmetric particle, which has not been detected. Other searches for dark matter particles among neutrinos have also not been successful. After 50 years of searching no Dark Matter has ever been found. It existence is purely a matter of faith.

20 big bang busting bloopers

The_Big_Bang_Theory_(Official_Title_Card)

There is about as much truth in the sitcom as there is in the actual big bang theory. Credit: Wikipedia

The following are 20 conundrums for the big bang theory for the origin of the Universe. These are problems in a universe which had no Creator God, but not in this Universe, created by the eternally existing uncreated One.

1. Where did the Universe come from? “Cosmology is not even astrophysics: all the principal assumptions in this field are unverified (or unverifiable) in the laboratory … .” Cosmologists have become “…comfortable with inventing unknowns to explain the unknown.” Dr Richard Lieu (University of Alabama, Huntsville)

2. How did nothing explode? Universe started in nothing not even space, time or energy. What fluctuated in the quantum vacuum if time did not exist and how do they know which laws of physics applied. Where did those laws come from?

3. How did stars and galaxies form? It is impossible to form a star without dark matter (or a nearby supernova, which is a chicken and egg problem). No stars means no galaxies which means no Universe. Dark matter is pure fiction!

4. The ‘Axis of Evil’ in the CMB anisotropies. Why a preferred axis? Why aligned with the ecliptic? There should be no preferred axes in the Universe. The CMB data from both WMAP and PLANCK satellites conforms a weird preference for a direction in the cosmos, which aligns with the orbit of the earth around the sun. Why?

Our eternal universe

Much has been written about the Universe, with its alleged big bang origin 13.8 billion years ago,1 with its expansion forcing all galaxies away from each other. And about two decades it was ‘discovered’ that the expansion is accelerating driven by some very strange form of energy – dark energy – that acts like an anti-gravity force, which is stranger than fiction. Yet the big question remains. What is the ultimate fate of the Universe? Secular cosmology does not have a precise answer, and I describe several of their scenarios below. However I believe that the Bible has the answer to this question. That answer may seem to many to be contrary to known science, but the same could be said of the creation of the Universe from nothing, whether it be by the action of the Creator God, or by secular physics invoking some quantum fluctuation of a metastable false vacuum.

Big bang fate of the Universe

Some believe the Universe will eventually die in a ‘big rip’,2 where space is literally ripped apart. This is alleged to result from the unlimited acceleration of the expansion of the Universe due to an unbounded increase in some very strange stuff called dark energy, for which laboratory science knows nothing. In that theory dark energy eventually becomes so strong that it completely overwhelms the effects of the gravitational, electromagnetic and weak nuclear forces, resulting in galaxies, stars and even atoms themselves being literally torn apart, at their core. See Fig. 1.

Others believe that the Universe will end in a ‘big crunch’.3 “Their calculations suggest that the collapse is “imminent”—on the order of a few tens of billions of years or so—which may not keep most people up at night, but for the physicists it’s still much too soon.”4 The big crunch is theorized to occur when the vacuum energy density (cosmological constant) becomes negative due to a change in some hypothetical scalar field changing sign. Details don’t really matter because it is really just ‘scratchings’ on pieces of paper.

Fig 1

Figure 1: The theorised expansion of a closed universe from a ‘big bang’ to a ‘big rip’ (or ‘big freeze’) and a contraction to a ‘big crunch’.

Yet another option, they say, is that the Universe will end in some unremarkable heat death, where every physical process just peters out. This is known as the ‘big chill’, ‘big freeze’ or ‘heat death’. In that view, the Universe continues expanding while gradually all thermodynamic free energy is dissipated, meaning that all motion eventually ceases. Over a hundred trillion years or so, they say, it comes to a state of maximum entropy at a temperature very close to absolute zero, when the Universe simply becomes too old and too cold to sustain life. All that they expect to remain are cold dead stars, cold dead planets and black holes.

These three scenarios (Fig. 1) are what comprise the secular belief system, the worldview most widely held by cosmologists today. It is based on pure materialism, that matter and energy is all that there is. The atheists believe there is no Creator, no God who loves us or has any personal interest in our destiny. Their beliefs are really pagan philosophy.5 Continue reading

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.

A 6000-year-old universe! Who says? Who cares?

Nowadays we are told, by so-called science, that the universe is 13.8 billion years old, that it all started in a big bang, and about 4.6 billion years ago the earth formed from a nebular cloud. Then 3.8 billion years ago life started on Earth and has been evolving ever since. The biblical narrative in Genesis, the first book of the Bible, gives us a very different time line of only about 6000 years. Which is correct? Why is this important? And who cares anyway? Dr Jim Mason presents some compelling arguments from both the scriptures and science that support the biblical account and fly in the face of the materialistic uniformitarian philosophy of so-called modern science.

Lecture was given August 1st 2015. See Age and Reason Seminar Adelaide for details.
