Insoluble scientific problems

Unanswered questions

Nature

There is a class of scientific problems, of central importance to humanity's understanding and control of the environmental crises with which it is faced, which is insoluble, either in the present or in the foreseeable future.

Background

The recognition of insoluble scientific problems emerged prominently in the early 20th century, as mathematicians and physicists encountered fundamental limits to knowledge, exemplified by Gödel’s incompleteness theorems and the halting problem in computation. These discoveries catalyzed global discourse on the boundaries of scientific inquiry, prompting philosophical and practical reassessments of research priorities. Over time, the persistence of such problems has underscored their significance across disciplines, shaping contemporary understanding of science’s inherent limitations.

Incidence

There are classic mathematical problems and conjectures that have defied solution for decades and even centuries. There are however also scientific problems relating to the environment which cannot be solved. Examples of such questions include: the extent and timing of global warming given increasing levels of "greenhouse gases"; long-term effects of exposure to low-level concentrations of certain compounds or to low-level radioactivity; or the degree of dependence of the ecosystems on particular levels of biodiversity.

Claim

Insoluble scientific problems represent one of humanity’s greatest challenges, threatening to stall progress and limit our understanding of the universe. Ignoring these unsolved mysteries is not an option; they are the very frontiers that drive innovation and discovery. If we fail to confront and prioritize these enduring questions, we risk intellectual stagnation and the loss of countless opportunities for advancement. Addressing insoluble scientific problems is absolutely essential for our future.

Counter-claim

Unanswered questions inspire and motivate scientific research. An enthusiasm for investigating mysteries leads to new discoveries. It is therefore essential to scientific investigation that there always be questions for which we have no answer.
