Scale Invariance and dark matter/dark energy

Click For Summary

Discussion Overview

The discussion revolves around the concepts of dark matter and dark energy, particularly in relation to scale invariance. Participants explore the implications of these ideas within cosmology, questioning existing models and interpretations while addressing the complexities of these phenomena.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant expresses confusion about dark matter and dark energy since 1996, suggesting that the increasing ratio of dark matter with expanding space might indicate an effect of empty space, which they believe has been overlooked.
  • The same participant praises Andre Maeder for providing insights into scale invariance, emphasizing its importance in the discussion.
  • Another participant warns against accepting the model presented in a linked paper, indicating that there are serious issues with it.
  • A different participant clarifies the distinction between dark matter and dark energy, noting that dark energy is associated with the expansion of space, while dark matter is described as ordinary matter that does not interact with light.
  • One participant humorously cautions against premature optimism in understanding these concepts, suggesting that complexities often arise.
  • Another participant encourages a broader perspective on general relativity and quantum theory, proposing that unconventional ideas could lead to new insights.
  • A later reply questions the initial participant's terminology, suggesting that they may have conflated dark matter with dark energy.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the interpretation of dark matter and dark energy, with some confusion about their definitions and roles. Multiple competing views remain, and the discussion does not reach a consensus on the validity of the models presented.

Contextual Notes

There are limitations regarding the assumptions made about dark matter and dark energy, as well as the definitions used by participants. The discussion reflects unresolved mathematical and conceptual challenges in understanding these topics.

The dark matter/dark energy issues has not made any sense to me since 1996 when it was evident that the ratio of dark matter increased as the volume of space measured increased. This was an obvious affect of empty space in the dark matter question that was being ignored. I thought at the time that it might have something to do with the affect of a gravity well on the passage of time. But that was not a valid concept.

Then along comes Andre Maeder, my new superhero, to solve this 25 year old thorn in my brain. Thank you Andre Maeder! The old guard is yelling about gravitational lensing and whatnot, but Scale Invariance. Scale Invariance. Scale Invariance. I could say it 100 times. Happy, Happy Happy.

I believe you are mixing dark matter and dark energy. Dark energy (very mysterious stuff) is supposed to increase as space expands. Dark matter is relatively ordinary stuff, but it doesn't interact with photons or ordinary matter.

And it all melts down... As my grandma used to say: don't get happy too soon. There's always a catch.
 
Try not to be so limiting and embrace the wondrous and confounding world of general relativity [or, if you prefer, quantum theory] where space, time and energy are viewed as interchangeable pieces of the same underlying puzzle. If you toss in an odd piece, close up the box and shake it vigorously, an unexpected and unique pattern will emerge

As mathman pointed out, you have "dark matter" where you mean (at least I hope you mean) dark energy.
