What’s the Matter5 with Matter?
In PHYSICS, our inability to detect the bulk of matter led many to question the assumption that
all matter is detectible. However, the Hubble Space Telescope (1998) stunned astronomers with
the fact that the universe is expanding faster than it has ever expanded in the past. The unknown
solution was called Dark Energy. Today, we postulate that the bulk of the universe is made up of
unobservable 27% Dark Matter, 68% Dark Energy with just 5% normal matter, which are made
up of baryons.6 Dark Energy is the force that pushes the universe further and further apart, causing
its expansion while Dark Matter forms the bulk of the universe’s mass, which restricts the universe
from blowing itself apart. This push and pull cosmic battle of force of energy against gravitational
mass makes it possible for the universe to exist. These strange parts of the universe were accepted
only after advances in technology made their undetectibilty indirectly detectible. The invention
of special telescopes allowed us to detect light coming in from different parts of the
electromagnetic spectrum, long wavelengths of infra-red, micro and radio waves, as well as the
short wavelengths of ultraviolet, X-rays and gamma rays. The story of Dark Matter and Dark
Energy goes back before the Hubble Telescope.
Dark Matter was proposed in 1933 by Fritz Zwicky to explain evidence of unseen (undetectable)
mass in the Coma Cluster (Abell 1656) of galaxies. It also accounts for the fact that the amount of
helium in the universe is much less than expected if matter is entirely baryonic, i.e., normal
observable matter that interacts with electromagnetic radiation and hence detectible by us. The
conclusion was that another kind of matter exists in the universe, and this was dubbed Dark Matter
(dunkle Materie). They are “Dark” because they are made up of exotic particles like MACHOs
(massive compact halo objects), elementary particles called axions or WIMPs (weakly interacting
massive particles), and do not emit or interact with electromagnetic radiation. In 1992 NASA’s
COBE spacecraft discovered anisotropy in the cosmic microwave background, meaning that the
stars in the universe are not evenly but rather directionally distributed, further suggesting the
evidence of Dark Matter. On 25 August 2016, astronomers at Yale accidentally discovered that
Dragonfly 44, an ultra diffuse galaxy (UDG) with the mass of the Milky Way galaxy, but with
nearly no discernable stars or galactic structure, might be made almost entirely of dark matter.7
Dark Energy was proposed in 1998 to account for the curious discovery by the Hubble Space
Telescope that the universe is expanding faster and faster. Some force is pushing things despite
the expected gravitational force to slow down expansion as matter gets further and further away
from each other. In 1998 supernova observations of accelerated expansion provided the first direct
evidence for Dark Energy, which was eventually accepted by 1999. As of 2013, the LambdaCDM8 model is consistent with a series of increasingly rigorous cosmological observations,
Matter is anything whose energy density scales with the inverse cube of the scale factor ‘a’, i.e., ρ ∝ a−3.
Radiation by contrast, has energy density that scales as the inverse fourth power of the scale factor ‘a’,
such that ρ ∝ a−4, and a cosmological constant lambda ‘Λ’, which is independent of ‘a’.

The ΛCDM (Lambda cold dark matter) or Lambda-CDM model is a parametrization of the Big Bang
cosmological model in which the universe contains a cosmological constant, denoted by Lambda (Greek
Λ), associated with dark energy, and cold dark matter (abbreviated CDM). It is frequently referred to as the
standard model of Big Bang cosmology because it is the simplest model that provides a reasonably good
account of the following properties of the cosmos: the existence and structure of the cosmic microwave

including the Planck spacecraft and the Supernova Legacy Survey (SNLS). Results from the SNLS
reveal that the average behavior (i.e., equation of state) of Dark Energy behaves like Einstein's
cosmological constant to a precision of 10%.9 Recent results from the Hubble Space Telescope
Higher-Z Team indicate that Dark Energy has been present for at least 9 billion years and during
the period preceding cosmic acceleration.
Today, there are at least 3 different theories to explain Dark Energy:
Property of space. Albert Einstein realized that empty space is not empty, and it is possible for
more space to come into existence. One version of his gravity theory that contains a cosmological
constant,10 makes a second prediction: "empty space" can possess its own energy. Because this
energy is a property of space itself, as more space comes into existence, more of this energy-ofspace would appear. This form of energy causes the Universe to expand faster and faster,
Quintessence (the 5th element), a dynamic energy fluid that fills all of space but affects the
universe’s expansion in opposition to that of energy and matter, causing the universe to expand
faster and faster, and
Einstein’s theory of gravitation is wrong, and a different theory is needed to explain why the
universe is expanding more and more rapidly.
In CHEMISTRY, water was ubiquitous and used for so many chemical reactions, but no one
knew what it was made of exactly. In the 7th century BCE, Thales of Miletus declared water to be
an element. In the 5th century BCE, Plato continued this assumption and named water as one of
the four elements of nature. He thought water was elemental. It took 2500 years from the time of
Thales before water was “discovered’ as a wet compound made up of two dry gases. This counterproductive reality stumped so many for so long. In 1800, Johan Ritter measured the amount of
hydrogen and oxygen produced by the electrolysis of water, confirming the earlier work of Henry
Cavendish who discovered hydrogen (inflammable air) and Antoine Lavoisier, who gave hydrogen
its name – “water-former” in Greek. This was a chemical example of how our inability to detect
components of air that fused to form water misled philosophers and scientists until the 19th century.

In 1917, a year after Einstein published his theory of general relativity, he created a cosmological constant
to account for the surprising fact that galaxies in the universe are not crushed by gravity but statically float
in space as if some hidden force was resisting gravity. At that time, no one knew that the universe was not
static. However, in 1929, Edwin Hubble announced that using a type of star called a Cepheid variable as a
"standard candle" to measure distances to other galaxies, observed the expansion of the universe. Einstein
bemoaned that introducing lambda, his cosmological constant to account for a static universe, was the
biggest blunder of his life. The knowledge that the universe is expanding led to the inference that it was
once smaller, and this led to the Big Bang Model. Today, most cosmologists think that with the discovery
of Dark Energy, Einstein has been vindicated.

In BIOLOGY, a great mystery needed to be solved during the 19th century to avoid needless
deaths from infection. When Louis Pasteur first suggested that microbes seen only with the aid of
microscopes were the causal agents of disease and food decay, there was great resistance, until
Robert Koch laid out the foundation of germ theory in 1905. With the discovery that bacteria and
viruses invade our bodies and compete with our somatic cells for resources, the image of what
constitutes us took on a different starting point. Today, each human body is seen as a colony of
100 trillion cells of which 90% are non-human in nature, living in symbiotic relationship with the
human cells. This was a biological example of how our inability to detect invisible life forms fed
the assumption that microbes do not exist, until microscopes enhanced visual detection.
From the examples above, we can see that the history of science is replete with circumstances
when scientific discoveries, technological innovations and medical advances change the scale and
scope of what constitutes scientific knowledge. The boundary that separates creation, nature and
non-nature may be more porous than we think.
So, what’s the matter with matter?
The fact of the matter is, we are still learning to describe, explain and detect matter as something
contrary to radiation and mostly unknown to us.11 For the Christian doctrine of creation, it
matters more than ever how we think about the appearance of matter. In creation or nature.

Matter is anything whose energy density scales with the inverse cube of the scale factor ‘a’,
such that ρ ∝ a−3. Radiation is anything whose energy density that scales as the inverse fourth
power of the scale factor ‘a’, such that ρ ∝ a−4. The cosmological constant lambda ‘Λ’ is
independent of ‘a’.
