motivations for MOND/TeVeS

Glenn Starkman 29.07.2008

  • C_l's are not independent because S_{1/2} is low
  • cosmic variance for alternative model not known if model not known
  • the antipodal anticorrelation is stronger in the full sky
  • other facts at the scale of about 1 matter horizon radius:
    • Pioneer anomaly
    • Omega_Lambda / onset of acceleration
    • DM
  • so many different strange things at a single scale suggest a single explanation
  • MOND is not relativistic, not dynamic, by its nature cannot say what to expect in many situations
  • TeVeS - tensor vector scalar theory - Bekenstein et al.
    • go from \Del . \Del \phi = 4 \pi G to \Del . (\mu \left(\frac{\Del\phi}{a_o}\right) \Del \phi) = 4\pi G
    • MOND -> TeVeS - dynamical and geodesic metrics are no longer the same (in GR they are the same)
    • Action is needed
    • subset of TeVeS are GEA(?) - generalised Einstein ether theories

  • DGP (example)
  • Birkhoff's Theorem important in all of this.
