Ask a Question
Something in an MKP article doesn't add up? Ask about it. Good questions can improve existing pages.
QUESTIONS • EVIDENCE • IDEAS
MKP Discussion
A place to question claims, compare evidence, suggest sources and help identify the next Murphy Knowledge Project deep dive.
The rule is simple
Challenge ideas, not people. Strong disagreement is welcome. Personal attacks, harassment, spam and deliberate misinformation are not. When making a factual claim, bring the best source you can find—and be willing to change your mind when stronger evidence appears.
What belongs here?
Bring Evidence
Share papers, archaeological reports, primary sources or credible reporting that supports—or challenges—an MKP conclusion.
Suggest a Deep Dive
Found an unusual scientific, historical or technological claim? Propose it for an evidence-based investigation.
Revisit a Conclusion
MKP conclusions are not sacred. New evidence can change them, and the reasoning should be visible.
Discussion standards
Separate observation from interpretation. Identify speculation as speculation. Prefer primary sources when they are available. Avoid posting private personal information. Do not copy large portions of copyrighted material; link to the source and summarize the relevant evidence instead. Claims involving medicine, archaeology, history or science should be evaluated according to the quality of evidence rather than how exciting the claim is.
Featured discussion: Mind uploading and digital identity
Could an AI preserve a loved one's memories or personality? If a digital replica continued learning, would it be the same person? Explore the science and philosophy, then bring your perspective to the open forum.

Featured discussion: Farming by biological cooperation
Should future agriculture engineer individual crops, or the entire system of plants, fungi and bacteria that supports them? An MKP investigation examines soil restoration, drought resilience and simulated space soils—including experiments that found no significant yield benefit.
- Crop or ecosystem? Which approach should receive more research attention: engineered crops, cooperative microbial communities, or both?
- Productivity or precaution? How should researchers balance possible yield gains with ecological risks?
- Evidence before deployment? What testing would be needed before using these systems on farms or in lunar and Martian habitats?
Bring different perspectives, ask hard questions, and challenge ideas without attacking people.

Featured discussion: AI-assisted medicines and targeted delivery
AI can help discover molecules and optimize nanoparticle formulations, but how do we ensure safety, affordability, and clinical evidence? Explore documented research, real-world implications and five open questions.

Featured discussion: Frontiers, megastructures and speculative futures
How should we judge ambitious proposals such as rotating space settlements, generation ships, Dyson swarms, planetary terraforming and advanced AI futures? The point isn't to reject imaginative ideas: it's to ask what is demonstrated, what is still being tested and what would have to be true for a proposal to work.
- Testable claims: What observation, prototype or calculation would raise or lower confidence?
- Engineering limits: Which materials, energy systems, risks or costs remain unresolved?
- Social choices: Who benefits, who bears the risks and what alternatives should be compared?
- Good sourcing: Share original research and link to creators such as Isaac Arthur without reposting their copyrighted videos, artwork or transcripts.
