The identification of dark matter — •Albrecht Giese — Taxusweg 15, 22605 Hamburg

The main theme of the dark matter phenomenon is that the galaxies, and also the stars around the galaxies, are rotating at too high a speed. It is considered to be one of the biggest problems in modern physics. This is because the traditional explanation of dark matter as particles, or alternatively a modified law of gravity (MOND), has been largely disproved. This concerns the assumption of special particles due to 'dynamical friction' around big galaxies with orbiting dwarfs, and MOND due to the motion distribution in dwarf galaxies.

The observable spatial distribution of the dark matter effect around galaxies and clusters leads to a solution, because it is identical to the distribution of photons. The result is a different - mass-independent - law of gravity. This contradicts Newton's law of gravity and Einstein's GRT, but is consistent with all observations. And so it is also a test of Einstein's interpretation of relativity.

This solution gives correct quantitative results where data exist, without using free parameters.
