The Question of Dark Energy — •Albrecht Giese — Taxusweg 15, 22605 Hamburg

Dark energy is considered to be one of the great mysteries of present-day physics. From measurements of the motion of type Ia supernovae, it has been concluded that the universe is undergoing accelerated expansion. To explain this acceleration, the universe is assumed to be filled with some type of ("dark") energy.

However, there is a very unspectacular explanation for these measurements if we follow the Lorentzian relativity rather than the relativity of Einstein.

In the Lorentzian relativity space is not expanding but always fixed and the stars and the galaxies are moving physically through this stable space. Inflation is in this view not a change of the space but a change of the speed of light c. And instead of a slowly expanding space one has to assume a slow decrease of the speed of light.

If in this view the speed of light was higher in the past there is a simple solution. Because if this higher c of the early times is inserted into the Doppler equation to determine the speed of the stars from their red shift, this will yield higher speeds for early stars. So there is no acceleration.
