20 Years of "Not Even Wrong"

Scope of the Discussion

• Thread centers on long-running criticism of string theory as “not even wrong,” and on how this reflects deeper issues in high‑energy physics and academia.
• Commenters assume familiarity with the article; they extend it with books, talks, and personal experience.

Testability and Status of String Theory

• Many argue string theory has produced no unique, testable predictions; when specific models are testable, there are infinitely many variants, undermining falsifiability.
• The “landscape” and anthropic reasoning are criticized as abandoning explanatory ambition.
• Some insist that without falsifiable predictions it’s closer to metaphysics than physics; a few suggest even “hypothesis” is too generous.
• Others note isolated predictive attempts (e.g., proton decay lifetimes) but stress these are just single models within a huge parameter space.

Funding, Careers, and Opportunity Costs

• Dispute over how “expensive” string theory is:
  • One side: direct grants are small versus collider costs; much money is private; mostly “coffee and chalk.”
  • Other side: real cost is diverted talent, faculty slots, and shaping of experimental agendas (e.g., collider designs driven by supersymmetry hype).
• Several describe string theory dominating high‑energy theory hiring and marginalizing alternative ideas for decades.

Sociology of Physics and Academia

• Recurrent themes: sunk‑cost careers, prestige hierarchies, and “personal brands” around research programs.
• Comparisons to epicycles and the “innovator’s dilemma”: established experts lack incentive to abandon the framework they built.
• Planck’s principle (“science progresses funeral by funeral”) is invoked; some see a generational shift away from string orthodoxy.

Alternatives and Remaining Frontiers

• Alternatives mentioned: various reformulations of the Standard Model, loop quantum gravity, twistors, neutrino physics, and condensed matter frontiers.
• Many note that alternatives share key problems: few or no clear tests; data at relevant scales is out of reach.
• Some argue particle physics may simply be in a “data desert”; without new experimental input, all programs risk drifting toward theology.

Public Perception and Science Communication

• Popularization of string theory is criticized for overselling speculative ideas, contributing to public disillusionment when promises fail.
• Others counter that science “worked” here: untestable programs lost credibility over time.
• Debate over best venues for communication: long‑form videos and blogs praised; short‑form social media seen as ill‑suited but unavoidable.
