Context: The cosmological concordance model ($\Lambda$CDM) matches the cosmological observations exceedingly well. This model has become the standard cosmological model with the evidence for an accelerated expansion provided by the type Ia supernovae

Despite the ability of the cosmological concordance model ($\Lambda$CDM) to describe the cosmological observations exceedingly well, power law expansion of the Universe scale radius, $R(t)\propto t^n$, has been proposed as an alternative framework. W

Cleaning up dark matter

As far as crowning achievements in physics go, discovering a fundamental particle of nature is hard to beat. Why else, for example, would physicists be spending billions of Euros on the Large Hadron Collider at CERN to look for the famous Higgs boson

In this letter, we show that Quantum Vacuum Friction (QVF) resulting from the interaction between the magnetic dipole moment of a pulsar and its induced quantum vacuum magnetic dipole moment should play an important role in how a neutron star's spin
