Universe may not be expanding!

In his recently published paper theoretical physicist Christof Wetterich claims that it is possible that the Universe is not expanding but instead the mass of all the matter is growing continuously. If this is the case the redshift of distant stars could still be explained, moreover, the mystery of that baffling initial singularity of the cosmos present at the moment of the Big Bang could also be solved. However, even if Wetterich's conjecture is right, it is still difficult to prove it experimentally given that mass is a dimensional quantity and can be measured only relative to something else. Therefore, a universal growth of all the matter in the cosmos could not be measured.

Wetterich's theory implies that our Universe was not packed into an infinitely dense singular point at the initial phase of the Big Bang but gained its mass and has been growing it since the moment of its birth. This idea would mean a huge turn in cosmology and philosophy and would have far-reaching consequences in our view of the world. It will be worth following his future work and the reactions of the scientific community. Read more about Wetterich's theory here.
