How I Learned to Stop Worrying

After a long bout of laziness and transport hang-ups I finally started attending Skeptics in the Pub again. For anyone unfamiliar with these types of event they are casual / enjoyable / laid back lectures and presentations on a variety of science and sceptical-based topics, the ones I previously attended discussed alternative medicine and psychic conmen.

The talk on Monday was titled ‘Progress in Astronomy’s Big Questions or How I Stopped Worrying and Learned to Love the 21st Century’ and was presented by Chris Lintott, an astronomer who works on the BBC’s Sky at Night. Chris was personable and engaging, and made what could possibly be very tricky information understandable and clear. The talk touched on a lot of topics within astronomy, which was great for an astropleb like me, though anyone more familiar with the subject may not have learned much, but that is the risk with any talk, I suppose.

Physics, with astronomy in particular, have a weird effect on me. This effect is characterised by i) existential dread, which then morphs slowly into being ii) seriously chilled out. Had I gone expecting this ‘drop tower’-style ride of emotion, I would not have been disappointed.

Some of the current theories and hypotheses of astronomy seem custom made to blow minds. The observation that only around 4% of the Universe is made from regular matter is deeply, deeply odd. It also suggests that use of the term ‘regular matter’ is ill-advised, given that since it’s in the minority that kind of matter is actually highly irregular. It is currently thought that 23% of all stuff in the Universe is dark matter, which is stuff that we cannot see, but whose effect is observable on ‘regular matter’. That is to say if a certain planet should be moving in a perfectly circular orbit (illustrated here O) and it isn’t, it follows that there is some invisible matter whose gravity is affecting it. Having climbed up to this level of understanding, it is then necessary to make another difficult clinb. We have matter: stuff we can see, dark matter: stuff we can’t see, and then in order to make calculations work in simulations, we get dark energy. We cannot directly observe dark matter, and from my understanding we don’t even know where or what dark energy is, how it works or where it’s coming from. However, when factored into calculations, we end up with models that correlate almost entirely with the Universe we see, which strongly suggests that dark energy is in fact there, and it makes up over 70% of what makes up the Universe.

It is this sort of information that leads to what I mentioned in point i). How am I meant to shield myself from complete intellectual meltdown when the vast majority of the Universe is made from something no one understands? I dabbed at my ears with a kerchief to stem the flow of brain (there’s little more embarrassing than rogue brain matter in a beard) and continued to listen as the topic changed.

So, according to Google the speed of light is 299 792 458 m / s, and I have no reason to distrust Google, after all it knows everything, and is my friend. And, of course, as we all know, nothing can go faster than the speed of light, right? Wrong, apparently. By this time my poor kerchief is aflood with grey matter, so fully has my brain been blown. According to observations, distant galaxies are moving away from us very fast indeed, of this much I was aware. However, I was informed, these distant galaxies are in fact moving away from us at around 40 times faster than the speed of light. I would have thought this would have been a problematic observation, but the solution to it is akin to stepping outside of the Matrix. The speed of light is not the fastest that anything can travel. The speed of light is the fastest that anything can travel THROUGH SPACE. The answer is that because space itself is expanding, this is contributing to the speed at which those distant galaxies are moving away. The speed at which space is expanding is not subject to the same limitations as are things moving through space, so it seems that it can expand however fast it bloody well wants to. At this point I’ve run out of brains and it is the actual structure of my skull that is now crumbling.

So with all the factors contributing to seemingly insurmountable levels of i), how does astronomy bring it back around?

The answer is stunning pictures and videos. Since Chris is a working astronomer, some of the talk was able to focus on very recent research, footage and images. He talked of the Sloan Survey Telescope in New Mexico which created a 3D map of large tracts of the local areas of the Universe, and we were also treated to images from the Hubble Deep Field telescope, which are always a delight. It is in these images that I find myself becoming ii). Such a simple technique, a pull back and reveal, applied to these pictures of such enormous complexity and depth, is so immeasurably soothing. As the picture pulls out, revealing layer upon layer of blips, swirls and clouds of light, each individually a galaxy, and as you focus on the foreground all the galaxies we have previously passed form a majestic, near infinite cloudscape in the background. Stunningly, stunningly beautiful. So, why does this in particular chill me out so much?

Perhaps the most fallacious component in the human psyche is our own inflated sense of self importance. It is very difficult for us to view any state of affairs from anything other than an anthropocentric vantage point. This is where all religion comes from in my opinion. We look at the world and from our observations we see a world, and in fact a universe, that doesn’t care about us at all. Humans indiscriminately die for no moral reason, simply due to the chaotic nature of things. This is an unpleasant situation to consider, and so there is no end of imagination and wish-thinking that we will go to in order to convince ourselves that this isn’t the case. For me, the deep field astronomical images are the perfect remedy for this problem. When confronted with this reality, it is impossible to countenance our wishful thinking. It isn’t negative to be freed from our fantasy in this case, for while it strips us of the false comfort of eternity and supernatural protection, the simple vastness of the scope of the Universe, for me at least, is an incredibly comforting thing. In my life I worry about a lot of things. Some of these things it makes sense to worry about: whether there is enough food to eat, a place to sleep, people around that I can rely on and whose company I enjoy. However, there are a large number of things I worry about that aren’t of any use. Wandering around alone in public I find myself very self-conscious, though in attempting to define the exact nature of that anxiety I find it difficult to actually explain. Am I anxious about people watching me, judging me? I think that is part of it. Also, days are filled with numerous unimportant encounters which, if you allow them to, can colour your life, bogging you down in petty concerns. These are the anchors which those images cut loose, for me anyway. I am vastly cheered by those pictures, because I can go about my business far happier, for a short while at least I am possessed of a fresh perspective which allows me to discount events and concerns for which there is no reason or function in allotting any importance.

I have been really cheerful ever since Monday, because I spent some time bathing in images of other galaxies.

Also I learned a little about the Universe where we live, in the company of pleasant people, and it only cost £3. All in all, time, money and effort well spent.

I believe a talk is planned for December if possible, though none is currently booked in. The next talk on the books of Cardiff Skeptics in the Pub is on Monday, February the 20th and is titled ‘Why Nothing Matters’. That sounds like I’ll be so chilled out afterwards I might need assistance leaving the building.

Comments are for Commenting

In a bid to get involved with my local community, I started reading the websites of a number of my local churches. They all seem to be doing some very good word, and providing very valuable services to the community, such as mother toddler groups, fundraisers and other events.


I found a blogspot account for one of the churches local to me, the St David's Uniting Church, which provides an account of the events that they put on in the church. In one post, here, seems to have been a talk which focused on 'sin'. I would say that this is largely understood as a religious concept, and as is so often the case though we have a general understanding of what 'sin' is, I realised I was unable to actually form a coherent definition that I feel people would agree to. After looking at a few dictionary definitions I found that at it's most basic it is an action which breaks a moral law.


If you click the link you can see the entire post, which isn't particularly controversial, but as I read it I felt that there were two conflicting accounts of what constituted 'sin'. I tried to comment on the post, since that is what the option is there for, but discovered that only the authors of the blog are allowed to comment there, so, having written out my comment, I felt slightly annoyed, and thought I'd post it here instead. Here it is:


*****


I'm not sure whether I'm misinterpreting what's been written here, but I think some of the thoughts on sin here are inconsistent.


In the third paragraph it says:


"Sin is not so much about moral misbehaviour as about lazy thinking - opting out of thinking for ourselves."


Which, it seems to me, would be advocating critical thinking, however in the next paragraph you say:


"It cannot be sinful to think as we have been taught, rather the sin is to refuse insights which are given to us, which would keep us honest."


Unless I am misunderstanding, you seem to be saying that you should both 'think for yourself' and also 'think as you were taught', which would seem to be contradictory.


I'm unclear if your sentence "think as we have been taught" refers to a method / way of thinking or whether it just means 'believe what you are told (presumably by someone in religious authority).


Apologies if I've simply misunderstood.


*****


I personally do believe it is very important to think for yourself, and to think critically. If the second point raised does imply that it is good to simply believe what you are told, I would vehemently disagree. They have phrased it very misleadingly if that is what they are suggesting, travelling an interesting linguistic route to justify simply believing as the church says. Unfortunately I was unable to ask them directly, so I may never know what they actually intended.

Skepticism

Recently I have become preoccupied by skepticism, rationalism, critical thinking and science, and I have been watching and reading widely on these subjects. My research efforts have been a little formless and scattergun, so I decided to start blogging about it in order to give more form to my efforts. I am intending it to be somewhere I can write as I learn, to serve as a tool to help me keep track of what I am learning about, and also, hopefully, serve in some small way as a link to a community which is growing ever larger in the world, and especially online.


Who am I and where am I coming from?


My name is Adam and geographically I am from the South Wales Valleys. I am an atheist, and while I've never considered, nor experienced anything that suggested, that position to be socially controversial, it seems that it is widely considered as a minority position, and so in the effort of upping awareness I have no reservations about broadcasting my position. I am an atheist because there is no evidence for the existence of a god/gods.


I would like to be able to say that all of my beliefs boil down to:


I believe in x because there is sufficient evidence to support it
or
I do not believe in y because there is insufficient evidence to support it.


Unfortunately that isn't the way life works, and I, as everyone else is, am subject to presumptions and trust in arguments from authority. I believe it is only a rational approach that can help filter out presumptions and falsehoods from actual truth. At this point in human history our knowledge is so vast that it is impossible for any individual to have tested and to conclusively know everything we have discovered or worked out as a species. No one person knows everything, and every individual has been wrong or mistaken at some point in their lives. I believe it is through a process of rational thinking, skepticism and critical analysis (and self-analysis) that we can discover what is actually true or correct.


I don't believe this aim is easy to achieve. This is why I subtitled this blog 'A Skeptical Effort', because being skeptical is a constant effort, it is not something you achieve and then have built into you and suddenly you can think critically about everything. It is something you have to work at, and it involves the willingness to alter your position if you discover you are wrong.


I have a degree in English Language and Communication which, of course, is of minimal use when it comes to scientific matters, but I would say it has made me very capable where it comes to picking apart illogical or inconsistent statements, and also gives me a grounding in research and analysis. Perhaps stating it in such a way is slightly hubristic, time and my efforts will show whether I am mistaken in my self-assurance.


I am eager to improve my scientific knowledge and understanding, which I have left wither somewhat since school, but I am actively taking steps to improve. While I have an interest in all things skeptical, the specific area of interest where I have an acute fascination is religion, as it has such clear and tangible positions on morality, where it's pronouncements, by their very nature, are not open to discussion or alteration, which I believe is a stubbornly ignorant position, and ultimately negative.


My aim is to always be learning and thinking, and using what I learn to be better in interacting with other people. I believe in the importance and value of discussion, and am seldom happier than when pointedly philosophising with good people. I hope that I am always trying to become a better writer. I write fairly often, though broadcast the writing less and less lately, and I also record vlogs, up until now on the topic of the Welsh language, and I also write, perform and record sketches, podcasts and videos with my friends, in a comedy group called The ACRE. I, increasingly infrequently, perform stand-up comedy. I enjoy reading (favourite author Haruki Murakami), playing games (favourite game Final Fantasy 7), watching good films, good comedy and anime regardless of how good it is. I have recently discovered the abundance of long debates and talks on youtube and I have become obsessed with them. Above everything else I value thinking and talking, by myself and with other people. I can't do very good impressions and I know very few jokes. I almost always have a beard of some kind, but I distrust moustaches.


That's some of me and Why.
