SUMMARY

The discussion centers on TeVeS, a modified version of General Relativity (GR) proposed by Jacob D. Bekenstein, which aims to explain astronomical observations without invoking dark matter. It draws parallels with Brans-Dicke gravity and the Modified Newtonian Dynamics (MOND) theory. The failure of the CDMS II experiment to detect dark matter directly is noted, alongside recent claims suggesting solar system observations may support the existence of dark matter. Relevant papers include the foundational work on TeVeS and the implications of these findings on our understanding of dark matter.

PREREQUISITES
  • Understanding of General Relativity (GR)
  • Familiarity with Modified Newtonian Dynamics (MOND)
  • Knowledge of Brans-Dicke gravity
  • Awareness of dark matter detection experiments, specifically CDMS II
NEXT STEPS
  • Read Jacob D. Bekenstein's paper on TeVeS
  • Explore the implications of solar system observations on dark matter theories
  • Investigate alternative theories to dark matter, including MOND
  • Review the results and methodologies of the CDMS II experiment
USEFUL FOR

Astronomers, physicists, and researchers interested in cosmology, particularly those exploring alternatives to dark matter and the implications of modified gravity theories.

I thought some people here might be interested in this paper on the status of TeVeS, which is a modified version of GR sort of like Brans-Dicke gravity, but with a motivation similar to that of MOND, of explaining astronomical observations without dark matter. Although CDMS II failed to detect dark matter directly ( http://arxiv.org/abs/0912.3592 ), there is a recent claim that solar system observations may confirm its existence ( http://arxiv.org/abs/1001.1697 ).
