Why is there a contradiction between SRT and GRT in strong gravitational fields? What is the cause of the relativistic effects? What is the contradiction in the expression ω = mc 2 when considering the cosmological redshift? What is the cause of Planck's uncertainty principle? Can we really simulate the Big Bang inside a particle accelerator? Are the universal natural constants really constant? What is the meaning of the so-called Planck units? Are there references to the universal natural constants? Can the unexpected result of the Supernova-Ia-Cosmology-Experiment also be explained without dark matter and increasing expansion? Why does the radiation curve of a black body have exactly this shape and no other? Is it possible to calculate the Hubble parameter and the CMBR temperature? Does the Machprinciple really apply? All these questions and more are answered by the present model without dark matter, without inflation, with variable natural constants and expansion. Since some of the variable natural constants also affect the observer, i.e. he is affected by them himself, some of the changes cancel out. A virtual relativity principle applies. The laws of nature just seem to be the same in all frames of reference. Changes in v4: Graphics redrawn, updated references, error correction.
