Ask Ethan: What should you do when a respected theory is false?
At every point in our quest to understand the world and universe — the one around us and the one within us — we can only start based on what we know and can imagine at present. We are biased by what we know and what we’re ignorant of, and we’re also influenced by the range of experiences that we’re aware of. Nobody has access to the full suite of evidence that all of humanity has ever collected,…
When a respected theory is found to be false, it's essential to approach the situation with humility and open-mindedness. Recognizing our own limitations and biases is crucial, as our experiences and knowledge are just a fraction of the vast, accumulated knowledge of the entire human population. We must remember that even the most respected theories have limitations and potential flaws.
One key aspect to consider is the consistency of a theory under different frames of reference. A theory that remains valid regardless of an observer's position, motion, or velocity is said to be Lorentz invariant, which leads to the conservation of CPT symmetry. This idea, which dates back to Galileo's time, has been a cornerstone of our understanding of the universe.
Newtonian physics, despite being superseded by Einstein's general relativity in certain scenarios, remains remarkably accurate for many practical applications, such as space travel and satellite orbits. However, at very small scales (quantum levels), high speeds (near the speed of light), or in strong gravitational fields, Newton's predictions begin to diverge from reality.
In such cases, we must embrace the scientific method and revise our theories accordingly. This may involve admitting that our initial beliefs were incorrect and being willing to discard deeply held, respected positions. It's also important to recognize that our personal experiences, while valuable, are limited and cannot replace the comprehensive, objective understanding that emerges from collective scientific inquiry.
Ultimately, when faced with a false theory, we should strive for intellectual honesty and a willingness to adapt our understanding of the world. This process not only strengthens our scientific knowledge but also fosters a more robust and adaptable worldview, where we remain open to new ideas and discoveries that may shape our future understanding of reality.
