Cold Dark Matter - Challenges

Challenges

Several discrepancies between the predictions of the particle cold dark matter paradigm and observations of galaxies and their clustering have arisen:

• The cuspy halo problem: cold particle dark matter predicts that the density distribution of DM halos be much more peaked than what is observed in galaxies by investigating their rotation curve.
• The missing satellites problem: cold particle dark matter predicts larger numbers of small dwarf galaxies (about one thousandth the mass of the Milky Way) than are observed.

All of these problems have a number of proposed solutions, and it remains unclear how serious a challenge they represent for the CDM paradigm.

Here is a simple proof Cold Dark Matter, CDM does not exist

Published WMAP data gives a Universe mass density ρ ~ 9.9 x 10^-27kg/m3. A radius R = 1.301x10^26m, and an observable Universe volume V = (4/3)πR^3 = 9.224x10^78m^3 give a Universe mass of 9.132x10^52kg. If the Universe mass is mostly due to electrons and protons with a combined mass of 1.673x10^-27kg, there are 5.46 x 10^79 of both electrons and protons in the observed Universe, matter being electrically neutral. The electron rest mass energy of 0.511MeV is rotationally relativistic by alpha ~1/137, so the effective mass energy in the particle's rotating frame is 70.02MeV, and has a wavelength of 1.77x10^-14m. The number of these wavelengths that just fit into the Universe radius is 1.301x10^26/1.77x10^-14 = 7.35x10^39. The` square of this number is 5.40x10^79, which is the number of electrons in the Universe as calculated above, within WMAP error. (ρ =9.8 x 10^-27kg/m^3 is a closer fit). This shows the Universe is a quantum construct.

Unless this is an incredible coincidence, essentially the entire Universe mass is due to electrons and protons, i.e. there are no CDM particles.

This analysis quantifies the Cosmological Holographic Principle.

Explanation: The electron is essentially a trapped photon propagating in a closed curved metric. Photons move at velocity c through observer space and are therefore two dimensional. So two orthogonal photons fill three dimensions. The number of electron wavelengths that can exist in the same volume is therefore the square of the number of wavelengths in a direction. So the Universe boundary area is the electron wavelength squared x the number of electrons in the universe. (1.771 x 10^-14)^2 x 5.4 x10^79 = 1.69x 10^52 = (1.301x10^26m)^2. This implies the Universe boundary is a curved metric.
