This past week I have spent a fair bit of time on “research” into my topic. By “research,” I am referring to viewing a lot of related material on YouTube and in fiction. More specifically, I watched the recent film “Tenet,” while also reading and reviewing material to help me better understand the film. I want to discuss the film in detail, but I think I will save that for the next blog post. In this one, I would like to share some of the material that I enjoy that helps me to understand the topics I write so much about.
In this post, I am going to share with you some of my favorite YouTube channels. The content creators of these channels do, what I consider to be, fairly good research into the topics they discuss. But more importantly, these creators raise very important questions and get me thinking about ideas I might not previously had thought about. The first on this list must be CGP Grey. His channel can be found here: https://www.youtube.com/greymatter/about
I admit I do not know a lot about the person behind this channel personally, but clearly by the sorts of topics he chooses, and by the way he tackles those topics, he is the sort of individual I tend to gravitate towards. My favorite video of all time, both on YouTube and probably on the Internet as a whole is his video entitled “The Trouble with Transporters” (https://youtu.be/nQHBAdShgYI). He begins by discussing the fictional technology of teleporters from the Star Trek series of stories, but that discussion quickly leads into very profound questions regarding the mind, the soul, and consciousness itself. Ultimately, it is his possible conclusion at the end of the video that best describes my belief regarding how consciousness might actually work. Of all the videos I try to encourage people to watch, this is always at the top of my list.
Also by CGP Grey is a video entitled “You Are Two” (https://youtu.be/wfYbgdo8e-8), where he discusses the discoveries made during the now very controversial, and even unethical, split brain (https://en.wikipedia.org/wiki/Split-brain) experiments from the 1950s and 1960s. I would emphasize here that what is considered ethically appropriate is a bit of a moving target, so those who performed these experiments were (during their time) not necessarily doing anything wrong; they were in many cases simply trying to help their patients live better lives. However, in the present day, in the part of the world where I live, it is considered very unethical to perform experiments upon humans, let alone human brains. Unfortunately, this sort of limitation presents key problems for the sort of research I might like to perform, as (it is my belief that) only through the experimentation on human beings can we ever truly hope to understand how something like consciousness actually works. This video is often the second video I encourage people to view.
CGP Grey has presented on many interesting topics, including some more recent videos about tumble weeds (much more interesting than you might think), but there is another creator that I need to shift to now: Kurzgesagt – In a Nutshell (https://www.youtube.com/c/inanutshell/about). Ironically, they too created a video related directly to CGP Grey’s split brain video, entitled “What Are You?” (https://youtu.be/JQVmkDUkZT4), where they continue the discussion. This video is definitely worth watching, especially if you watched CGP Grey’s part of the discussion. However, Kurzgesagt’s library of videos dwarf’s CGP Grey’s. I suspect this is because Kurzgesagt may have a much larger team of people working on these videos.
The first Kurzgesagt video I usually recommend to people is their video entitled “Optimistic Nihilism” (https://youtu.be/MBRqu0YOH14), probably because it expresses the world view that I happen to hold. Specifically, the video is presenting the idea that there is no inherent meaning or value in the world, and so we (as conscious entities) are responsible for creating meaning and value in this world; that this responsibility is something to rejoice about. I would argue that the title of the video is a bit misleading, as nihilism is the viewpoint that there is no meaning or value, period, whether intrinsic or otherwise. For a nihilist, I cannot assign meaning, because my attempting to do so fails at the outset. There simply is no meaning in anything, period. The video might better be entitled “Optimistic Existentialism,” as the Existentialists probably more closely presented a viewpoint consistent with the ideas the video is proposing. For an Existentialist, such as Simone de Beauvoir (https://en.wikipedia.org/wiki/Simone_de_Beauvoir), what makes humans unique in the world is their ability to generate meaning and value in a world that would otherwise be void these things; that the world has no intrinsic meaning, and our freedom (or free will) is precisely what makes the generation of meaning and value possible. For Beauvoir, this idea leads into ethics, suggesting that how humans ought to behave is in such a manner as to support the freedom of those around themselves, allowing for everyone an opportunity at meaning and value generation. This, I admit, is my interpretation of Beauvoir’s ideas, especially from her work “The Ethics of Ambiguity” (https://en.wikipedia.org/wiki/The_Ethics_of_Ambiguity).
Other videos by Kurzgesagt, that I consider noteworthy, include: “The Origin of Consciousness – How Unaware Things Became Aware” (https://youtu.be/H6u0VBqNBQ8), a discussion on consciousness itself; “Emergence – How Stupid Things Become Smart Together” (https://youtu.be/16W7c0mb-rE), a discussion on how consciousness might possibly come about; and “What Happens If We Throw an Elephant From a Skyscraper? Life & Size 1” (https://youtu.be/f7KSfjv4Oq0), the first part of a series that gives serious thought to the significance of the size of things (what I have often referred to as “scope”). These videos are the sort I enjoy, but Kurzgesagt does plenty of videos about virtually anything, including Universal Basic Income (https://youtu.be/kl39KHS07Xc), ants (https://youtu.be/cqECNYmM23A), and even Dyson Spheres (https://youtu.be/pP44EPBMb8A).
I have to admit, aside from the rather deep topics these channels choose to discuss, I am also smitten with their animation styles. As one who is frequently minimalist in nature, their generally simplistic animations (I believe) really allow for their discussions to shine through without being impeded by fancy special effects in order to attempt to convey the sometimes challenging ideas. This leads me to the latest channel that I have recently discovered that I will now share with you: minutephysics (https://www.youtube.com/user/minutephysics/about).
Honestly, it is strange to me not to have stumbled upon minutephysics sooner, as they have created videos about many of the things I’ve been discussing in this blog for a while. For example, my lengthy discussion regarding how time is an inconsistent measure, synchronized to the irregular idea of a day is presented much more succinctly in just over three minutes in his video entitled “Why Some Days Aren’t 24 Hours” (https://youtu.be/Vxz6nNqpDCk). I’ve only just discovered this channel, but I expect there are plenty more interesting videos for me to watch, and I will view them in the coming days, weeks, months, etc.
The first video that I watched by minutephysics was “Solution to the Grandfather Paradox” (https://youtu.be/XayNKY944lY), which is an honest to god solution to a paradox. (Actually, as he suggests, it is a proof suggesting that the Grandfather Paradox is not a paradox at all, as there is a reasonable solution to the problem, so long as you have some familiarity with Quantum Superposition (https://en.wikipedia.org/wiki/Quantum_superposition). While I expect some might want to dispute this claim, I find his solution both elegant and thought provoking. Essentially, he is thinking outside the box, using quantum physics in order to try and resolve issues that may otherwise be considered unresolvable. In truth, until we are able to time travel, in order to test out such theories, this is all speculative at best. However, this is clearly an excellent attempt at resolving a very complicated problem, without simply throwing one’s arms into the air and giving up. Another interesting solution to another paradox is “Complete Solution To The Twins Paradox” (https://youtu.be/0iJZ_QGMLD0), where he suggests the answer lies in understanding the rotation of time.
It is in this last video that we come full circle. Toward the end of the video, he briefly discusses the relativistic effects behind flying a plane around the Earth, moving in the direction of rotation, while carrying an atomic clock. This, is clearly a reference to the Hafele–Keating experiment from 1971 that I discussed in my previous two posts. Realizing this, I simply had to continue investigating this YouTube channel, and why I am presently sharing this all with you today. Put simply, I am clearly not the only person who has had these thoughts that I have, and people much smarter than I am have been considering these questions for a very long time. I am not alone.
The results of these various discoveries has led me to the realization that in order to coherently speak on the topic of time, I will require much, much more education. In fact, I honestly believe that if I am to have any hope of answering my initial question, I will need to enter into the field of quantum physics proper. Coupling my understanding of philosophy and computers with quantum physics just might make it possible to really answer these sorts of questions. On the other hand, I may simply find a more creative solution to a paradoxical problem, but I’d be okay with that too.
In my next blog post, I plan to discuss the film Tenet in more detail. I will consider what the film is suggesting about time and space, and show how the film suggests there is no such a thing as freedom at all. And, as I will reiterate in that post, there will be spoilers for those who have not yet seen the film.
