ToK Blog Post #16 – Andy Fletcher’s ‘Life, the universe and everything’

Before the holidays, we were visited by an experienced lecturer who gave a presentation entitled “Life, the universe and everything’. In my opinion, his presentation was really, really interesting. I think a big part of why I like it so much is because it dealt so much in physics, and not just the dry, obvious, -and sometimes boring- world of Newtonian physics, but it dealt with the more abstract and exciting principles of Einsteinian physics – relativity, space-time, and more. I could make a long list of reasons why I liked this presentation, but that wouldn’t really do anyone any good. Instead, I’d like to respond to some of the comments I heard about the presentation, because there were times where I disagreed.

One of the comments that I heard or read a lot was that the presentation was not actually a ToK presentation. In some respects, these comments were true, the presentation was not fully and entirely a ToK presentation, but I thought that the presentation had a lot more ToK in it than most people gave it credit for. The beginning was all about the inherent weaknesses of scientific theory and scientific evidence – and we all can see the ToK in that; it puts into question the anachronistic and all-too-widespread image of science as founded only in cold, hard logic, and it puts into question the blind faith that we seemingly put into science to be right.

I thought that this idea – the transience of scientific theories and the fallibility of scientific discoveries as a whole- was demonstrated very well in the later parts of his presentation. He showed us and explained to us 3 distinct ‘eras’ or where there were mainstream theories that dominated and dictated the mindsets of the people back then, including the geocentric universe, flat-earth paradigm, the Newtonian paradigm of a infinite universe, and the Einsteinian revolution. It was interesting for me to see how in each era, people put so much faith in their respective mindsets (to the point verging on being arrogant – with the examples of scientists inaccurately claiming that “There is nothing new or worthwhile in science to be discovered any longer”… or something to that extent), only to be proven fundamentally wrong later on. This kind of puts our own era of science, and our blind faith in its exterior of hard logic, into some perspective.

The presenter later on went into detail about the physics concepts and how the scientists derived them. I noticed that it was this part that most people disliked and claimed was too far removed from ToK, but I disagreed with this the most. I thought that this literally dealt with the essential ToK question: “What do we know and how do we know it?”, albeit applying mostly to knowledge in physics.

I also felt that one of the ideas presented in the later parts of the presentation were so ToK-ish that I was surprised no one brought it up in class. Mainly, the idea of the Strong Anthropic Principle (SAP). The SAP states that the Universe was designed in order for observers to be borne and in order to sustain them; and that the observations of these observers are essential to the existence of the Universe – without any observers, the Universe would not exist. This reminds me of that old and well-known philosophical question: ‘If a tree falls in the woods and no one is around to hear it, does it make a sound’? In fact, I think that that question is a product of the SAP. I’m not sure if I know the answer to that question, nor am I sure of the validity of the SAP, but it’s comforting to think that our existence isn’t just a random, meaningless occurrence.
