Exploring the Limits of Human Knowledge: What We Don't Know
Written on
Chapter 1: The Illusion of Knowledge
For a significant portion of my adult life, I was deeply engaged in my career and daily routines, believing I was well-informed due to my consumption of newspapers and selected literature. However, a few years back, my circumstances shifted, allowing me more time for exploration. Intrigued by various subjects, I delved into books and studies, reveling in the opportunity to truly comprehend how things work. To my astonishment, I discovered that many topics, including some fundamental concepts, lead to the realization that human knowledge has its limits.
Despite the overwhelming amount of information available, many accepted truths, even those taught in schools, can often be misleading or entirely incorrect. Rest assured, I haven't succumbed to conspiracy theories; my focus is on the basic misunderstandings we all share.
Section 1.1: The Unknown Proportion
Physicists suggest that we only understand about 2% of the universe, leaving a staggering 98% as a mystery. This 98% doesn’t refer solely to the distant cosmos, but rather to the elements of our immediate surroundings that remain largely unexplored. Yet, even within that tiny 2% of knowledge, our grasp is often tenuous.
Subsection 1.1.1: Gravity: A Complex Phenomenon
Consider gravity—commonly attributed to Sir Isaac Newton, who famously discovered it when an apple fell on his head. He formulated a widely used equation: F G = m ? g. However, this depiction is not entirely accurate. While Newton's formula yields reasonable approximations across a variety of distances, it falters at both extreme and minuscule scales, raising questions about the validity of a formula that only works within certain parameters.
Section 1.2: The Chaotic Universe
Another fascinating topic is the three-body problem, recently popularized by the Netflix series titled "Three-Body Problem". Despite extensive knowledge regarding the orbits of celestial bodies, the interaction of three planets leads to unpredictability. While we can calculate the trajectories of two planets with precision, introducing a third creates a chaotic system. Even slight alterations in simulations can cause drastic changes, demonstrating the inherent instability of such systems.
Chapter 2: Examples of Our Limited Understanding
The first video, "Alex & Sierra - Little Do You Know," explores themes of emotional complexity and hidden truths, perfectly aligning with our discussion of knowledge.
The second video, "Alex & Sierra - Little Do You Know (Cover)," showcases the reinterpretation of familiar narratives, much like our need to reassess what we believe we know.
Numerous examples illustrate our limited understanding:
- The notion of "renewable energy" as a panacea, despite unresolved foundational issues that may lead to unintended consequences.
- The promotion of electric vehicles and industrial processes without addressing energy source challenges.
- The faith in hydrogen as a revolutionary solution, despite its inefficient production and transport.
- In medicine, numerous ailments remain enigmatic, with treatments often being a matter of trial and error.
- Historical data revealing that regions with fewer medical resources can achieve health outcomes comparable to those with significantly more.
- Climate models that grow increasingly chaotic as they incorporate too many variables, resulting in unreliable predictions.
- Investments in particle accelerators driven by theoretical constructs that may not hold up under scrutiny.
- Ongoing debates about the impact of CO2 on global temperatures, which remain unproven.
- The Big Bang theory itself, a hypothesis proposed nearly a century ago, underscores the uncertainty that permeates our understanding of the universe.
Indeed, little do we know...
