Many cosmologists accept “Dark Energy” as representing today about 70% of all mass-energy of the universe and think it’s increasing every day. Where does it come from if the universe is all there is? A universal model should be based on laws of physics, energy conservation and constants of nature being constant. Emmy...

The age of our universe depends on the estimate of the Hubble constant. Recent measurements (WHAP, Planck, ed) would mean an age of more than 14.5 billion years. This article takes a different approach, based on Noether’s theorem on energy conservation and the comoving coordinates of Robertson and Walker. The age now...

The Hubble law (1931) relates the speed of a galaxy to its distance. The Hubble law works well for galaxies within our local group, but was never meant for highly redshifted galaxies, since it is based on the non-relativistic Doppler Effect. For highly redshifted galaxies, like GN-z11 with a redshift “z” of 11.1,...

The laws of physics in proper frames (at high speed for example) are limited in their applicability. In the Large Hadron Collider (LHC) at CERN high speed particles are being researched. A key question is, to what extend can a (hypothetical) proper observer, travelling along with a proton in the LHC, apply the laws of...

How do you measure? Crucial is which measuring stick or [unit] is used to read the amount or coordinate on your display. Einstein originally didn’t talk about ‘length contraction’ (amount) but about ‘measuring stick contraction’ (unit). Remarkably Einstein’s theories are cast in mathematical formulas using coordinates...

  Remarkable? Andromeda goes 20% faster than stated in many books and publications. So you see: Our repair-project leads to many consequences and predictions. This article is about the famous Hubble law. The law is explained, analysed and grilled. The measured redshift of our today’s most far spotted galaxy GN-z11...
