My Top Astronomical Anomalies: A List

The Universe is filled with mystery. There are a myriad of things that are, but shouldn’t be, or probably shouldn’t be. Adequate explanations are not only lacking, but even the wildest possible theoretical explanations are rather thin on the ground. There often tends to be a massive divide between observation and theory. These anomalies run the range from the Universe as a whole, down to your local neck of the woods, well the solar system anyway. Here are a few my favourite astronomical anomalies.

THE BIG BANG EVENT: This is no doubt a concept that nearly everyone has heard about, and swallowed hook, line and cosmological sinker because scientists present this creation of the Universe scenario as fact. It’s not fact; just the most viable theory of many theories and it has serious flaws. The accepted theoretical account of the creation or event that kick-started our Universe off not only has that event a something that created all of matter and energy, but all of time and space as well, and this creation event, to boot, all took place in a volume less than that of a pinhead (something in the realm of the quantum) and for no apparent reason at all. First there was nothing; then there was something. Wow!

At best observations that support this are indirect being made some 13.7 billion years after-the-fact. Those indirect observations that provide evidence for the Big Bang event are the fact that the Universe is expanding; the Universe has a temperature – the remnants from the hot Big Bang called the cosmic microwave background radiation (CMBR) and the amounts and ratio of hydrogen to helium. In reality there are no direct observations as nobody was present at Ground Zero all those billions of years ago.

There are really a couple of anomalies present in the standard Big Bang account. 1) You have a violation of causality – something (space, time, matter and energy) created from nothing which is a violation of several conservation laws or relationships. 2) You have a violation of pure common sense that tells you that you can not stuff the contents of the entire Universe into the realm of the quantum, something actually way less in volume in fact than a pinhead. If that’s not anomalous, I don’t know what is!

ACCELERATING UNIVERSE: The anomaly here is quite straightforward in that there’s considerable observational evidence that the expansion rate of the Universe is accelerating. However, logic dictates that because of the overall gravity that the Universe has, the expansion rate of the Universe should be decelerating. The ‘antigravity’ energy required to accelerate the Universe’s expansion has to come from somewhere, and in ever increasing amounts to keep on keeping on the ever increasing rate of acceleration, yet, the Universe, almost by definition, already contains all there is and ever will be. If extra ‘antigravity’ energy is being created, it’s being created out of nothing. Something from nothing is a clear violation of the basic conservation laws and principles that form the bedrock of modern science.  

DARK ENERGY & DARK MATTER: When considering all things cosmological, it’s become apparent that astronomers only observe about 4% of the matter plus energy that should be present. That is, about 96% of the matter plus energy that should be present and detectable to account for the observed behaviour of our observable universe is missing! Now 1% might be understandable given measurement uncertainty (error bars), but hardly 96%! So, cosmologists have postulated concepts termed ‘dark matter’ and ‘dark energy’ to make up the deficit. However, nobody has the foggiest idea what exactly ‘dark matter’ and ‘dark energy’ actually is. Neither has actually been detected either out there on in the laboratory down here – obviously. The anomaly here is that ‘dark matter’ and ‘dark energy’ are both ad hoc theoretical concepts to make sense of various astronomical observations, but without benefit of any actual observation of ‘dark matter’ and/or ‘dark energy ’to back things up. That’s a rather slight-of-hand trick, and until cosmologists put actual observational money on the board where their theoretical mouth is, it’s all an anomalous pie-in-the-cosmic-sky.

MATTER-ANTIMATTER RATIO: In our Universe, there should theoretically be equal amounts of matter and antimatter created at the time of the Big Bang, but there’s not. We observe a Universe made out of matter. Our antimatter has gone walkabout. Why is it so? That question illustrates a big anomaly that doesn’t have a really satisfying answer. Mother Nature shouldn’t favour one form of matter over the other, yet apparently that’s the case. Perhaps that’s just as well. A Universe that’s 50% matter and 50% antimatter will ultimately become a Universe of just 100% radiation or energy, and thus no material you and no material me.

MONOPOLES: We all know about magnetic fields having two sides, whether it’s a bar magnet or the Earth’s magnetic field (or those part and parcel of many other astronomical bodies) – there’s a south pole and a north pole; a positive and a negative. It will probably come as a surprise that there should also be a monopole – a magnet with just one pole, north OR south; positive OR negative. That’s because one of the many Big Bang ‘in the beginning’ predictions of all things theoretical is the existence of magnetic monopoles – magnets with either a south pole or a north pole, but not both. Alas, we’ve never ever found and confirmed the reality of even one monopole, so theoretical prediction and observation are not in harmony. In other words, an anomaly exists.

QUASARS: Quasars are ‘quasi-stellar objects’. They are ‘stellar’ because they aren’t all that large (like a galaxy). They are ‘quasi’ because they give off energy way, way, way more times greater than any star known in any astronomical catalogue. They seem to be primordial objects – they formed long ago and are now far away.  Quasars, like stars or galaxies, are their own entities and if two or more show a very close and special causality relationships then they should show identical recessional velocities (since the Universe is expanding and they are part of the Universe and that expansion). Recessional velocities are measured by an object’s red-shift. Theory identifies red-shift with velocity. However, you apparently have some observations of causality connected quasar pairs with vastly differing red-shifts (measurements of their recessional velocities). The anomaly, in an analogy, is that you can not have a runner running at 15 miles per hour holding hands with another runner running at 3 miles per hour!

NEITH: Neith is, or was, the now-you-see-it-now-you-don’t. now-forever-lost satellite of our twin planet (in size if nothing else), Venus. The anomaly here is that bona-fide professional astronomers, not one but numerous celebrated astronomers, including Giovanni Cassini (1625-1712), sighted, noted and logged the existence of the damn thing and wrote up their findings in their professional journals. Okay, the time period was the mid-1600s to mid-1700s, but the professional eyeballs and the professional equipment was good enough to verify one way or the other the presence or absence of a reasonably sized natural satellite in orbit around Venus.

Of over thirty sightings of Neith, the best known and verified were in 1645, 1672, 1686, 1740, 1759, 1761 and 1764 (multiple sightings on numerous days in March). Observations over that stretch of period would seemingly rule out the ‘satellite’ being a faint star or asteroid or outer planet like Uranus or Neptune that just happened to be way beyond Venus but in the direct line of sight. Sometimes the observed phase of Neith matched the phase of Venus, which again suggests that the object was in close proximity to the planet.

Venus, inward and closer to the Sun than Earth, is a very visible and prominent celestial object when viewed from Earth, commonly called the Morning and Evening ‘Star’. We’ve all seen Venus; in fact if you know exactly where to look it can be seen in the daytime sky. Venus is far enough away from the Sun that the Sun’s glare doesn’t drown out reflected light from Venus, and presumably any objects near or in orbit around Venus. A natural satellite of Venus of any reasonable size should be readily detectable with the astronomical equipment available at the time. And so it really didn’t raise any astronomical eyebrows when Neith was in fact discovered. The anomaly here is that all and sundry were wrong. Neith doesn’t exist. Venus has no natural satellite(s). Now either all and sundry were totally incompetent and wouldn’t know one end of a telescope from the other, or else Neith really existed but somehow exited the local neighbourhood. If that’s the case, then Neith wasn’t natural at all but under intelligent control, and not by any terrestrial intelligence. What Neith was, and where it disappeared to, are major anomalies. 

From the examples above, I conclude that it almost seems as if someone (something) is ultimately responsible for our Universe, but he / she/ it / they didn’t quite think things through sufficiently. Methinks an all knowing, all powerful supernatural God type being wouldn’t have stuffed things up. So either the Universe is naturally stuffed up, or it was created stuffed up!

  1. Thanks for the information! I never knew about Nieth before and am intrigued. I hope to read more from you in the future.
