Transfer of atomic mass with a photon solves the momentum paradox of light – Aalto University

http://www.aalto.fi/en/current/news/2017-06-30/

In a recent publication, Aalto University researchers show that in a transparent medium each photon is accompanied by an atomic mass density wave. The novel discovery solves the centennial momentum paradox of light. 
If this theoretical finding is proven true with experiments, it can affect our understanding of universe:

“Presently the Hubble’s law is explained by Doppler shift being larger from distant stars. This effectively supports the hypothesis of expanding universe. In the mass polariton theory of light this hypothesis is not needed since redshift becomes automatically proportional to the distance from the star to the observer”, explains Professor Jukka Tulkki.
