Discussion Overview

The discussion revolves around the status of 'Dark Flow' in the context of cosmology, specifically whether it is considered a fringe theory. Participants explore the current understanding and consensus regarding this concept, touching on observational and interpretational aspects.

Discussion Character

  • Debate/contested, Exploratory, Conceptual clarification

Main Points Raised

  • One participant expresses curiosity about the general consensus on 'Dark Flow' and its classification within the community.
  • Another participant suggests that 'Dark Flow' may have been debunked as an observational or interpretational mistake, indicating uncertainty about the current status.
  • A third participant describes 'Dark Flow' as still appearing speculative, reflecting a lack of confidence in its acceptance.
  • A later reply references a specific paper that purportedly refutes earlier claims of 'Dark Flow', while questioning the definition of "fringe".
  • There is mention of upcoming results from the Planck satellite that may provide further clarity on the topic.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether 'Dark Flow' is a fringe theory. Multiple competing views are presented, with some suggesting it has been discredited while others maintain it is still a speculative idea.

Contextual Notes

There are limitations in the discussion regarding the definitions of "fringe" and the specific criteria for classifying theories in cosmology. Additionally, the reliance on forthcoming data from the Planck satellite introduces uncertainty about future interpretations.

I am curious if 'Dark Flow' is considered a fringe theory or not. I have been away from cosmology for a while and am trying to pick up the general consensus of the community on the leading theories today. Thanks.

I'm speaking from a base of pretty much utter ignorance, but I seem to recall some time back that dark flow had been basically discovered to be an observational mistake ... or perhaps it was an interpretational mistake, but in any case I think the whole thing went away. If others have more correct information, I'll be happy to hear about it.
 
Dark flow still looks very speculative to me.
 
Okay, thank you.

The above link is a pretty strong refutation of the previous claims of dark flow. I am not sure what your definition of "fringe " is though. Planck should shed more light on this when it release results early next year.
