Discussion Overview

The discussion revolves around the viability of Modified Newtonian Dynamics (MOND) as an alternative to dark matter in explaining cosmic phenomena. Participants explore the contrasting views on MOND and dark matter, referencing experimental evidence and theoretical implications.

Discussion Character

  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant questions why two teams studying MOND did not compare their experiments, suggesting a potential difference in methodologies.
  • Another participant expresses skepticism about MOND's acceptance, noting that it fails to address many phenomena, while also acknowledging that dark matter is not definitively proven.
  • There is a query regarding the timeline for discovering dark matter particles, referencing a statement by Sean Carroll about the implications of not finding them within a few years.
  • A later reply indicates a lack of knowledge on the matter, reflecting uncertainty about the timeline for dark matter discovery.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the efficacy of MOND versus dark matter, with some favoring dark matter while others remain open to the discussion of MOND. The timeline for potential discoveries remains unresolved and speculative.

Contextual Notes

Participants express uncertainty regarding the experimental evidence for both MOND and dark matter, highlighting the complexity of the topic and the limitations of current understanding.

Hello Everbody
In Sci Shows newest video they take about alternates to Dark Matter and one of these is Modified Newtonian dynamicse. The guy states that there were two teams one proved that it existed and the other did the the opposite.
My question is why they can't and didn't compare there experiments?. There must be a difference in their experiments.
Thanks for any answers

I haven't watched the video but here's my take on the issue: MOND is generally not in favor, as there are too many things it doesn't handle, but it has not been totally discredited. Dark Matter is more in favor but it too is not a sure thing. Dark matter particles have never been observed, but not for lack of trying.

how many years do you believe until we might find them? I heard Sean Carrol talking to Joe Rogan saying if we don't find it within the next 2-3 years we might have to question our theories? Is that actually the case?

That's all beyond my knowledge
