Why is dark matter assumed to exist in the cosmos? From reading news headlines you would think it has been clearly identified and that we now know so much about this once elusive stuff. It has been sought in many different laboratory experiments for more than four decades now, but never found. Why then are astronomers so confident it is out there? Let me try to put this into context and I hope it will become clear. Continue reading
In his book “Dark Winter, How the Sun Is Causing a 30-Year Cold Spell,”1 John L. Casey outlines a distinctively different interpretation of so-called ‘global warming.’ Casey makes the claim that, in 2007, he announced to the world, to those who would listen anyway, that the Earth would from that time on undergo a massive cooling period, which would last for about 30 years.
Casey developed his theory around what he calls solar hibernation. This is an expression to describe the state of the Sun when it exhibits a long period of low sunspot number. That is called solar minimum by the space science community.
Casey documents a theory that the Sun is absolutely the main driving force for Earth weather. Solar irradiance is the energy flux experienced at the Earth, and human kind cannot do anything about it.
There are many websites, both for and against anthropogenic global warming, now called ‘climate change’ but Casey’s theory is different. He is not the only engineer or scientist to notice a correlation between sunspot activity and global temperatures, but he adds 32 other physical reasons (lines of evidence) that corroborate his theory, in Appendix 3 titled: “Press Release: Global Warming Has Ended; the Next Climate Change Has Begun.” Continue reading

Over years of researching cosmology and astrophysics, I have argued that ‘dark matter’ is a sort of ‘god of the gaps’,1 the ‘unknown god’. It is proposed mainly to rescue the standard big bang model from problems when a mismatch is found between the theory and some observations. However, secular cosmogonists (scientists who study the beginning of the universe) usually believe the big bang worldview to be correct as well as all its associated astrophysics. So they must postulate something invisible to explain the discrepancy. This ‘something’ is ‘dark matter’, a hypothetical substance that emits no light or radiation, so cannot be seen.
Several years ago, astronomers claimed that they now had direct empirical proof of the existence of ‘dark matter’.2 This was dutifully repeated in the popular media.3 It was claimed that this demolishes the criticisms of ‘dark matter skeptics’. The section entitled “Dark Matter Proof?” (below) explains this further, and shows how there are many competing explanations for the same evidence. Continue reading
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.

When God said He created everything in order that He did according to the Genesis 1 account then all those events occurred as the Bible describes on those consecutive 24-hour days about 6000 years ago. Lisle proposal is that those events were timed when the light first arrived, or when a hypothetical Earth-bound observer might have first observed them happening. And the main issue is the creation of the stars and galaxies, some of which lay tens of billions of light-years distant. So if we only consider the language of appearance, the light from those galaxies, and all stars, first arrived sometime during Day 4 of Creation week. Therefore travelling at constant speed of light (c), which means light travels 1 light-year per year, then it would have taken billions of years to get to Earth. Therefore such a view of the universe requires that all galaxies were created at a time long before God created the Earth on Day 1 of creation week. But this is just language of appearance. A constant speed of light (c) assumes a certain convention of synchronizing clocks. We could equally have chosen another convention that simply times all events when they are observed. So when the light of the ‘newly’ created stars and galaxies arrives at the Earth on Day 4, it is truly the first light from the creation of those galaxies. In my view, the only question to answer with this model is: Is it compatible with Scripture? Continue reading
