Fast radio bursts by stellar wind microlensing of a faint background source
Richard Lieu
By assuming the inverse square law of solar wind plasma density as representative of other stars, it is shown that just outside a star the {\it outward} deflection of a passing rad…

Are dark matter and dark energy omnipresent?
Richard Lieu
A set of temporal singularities (transients) in the mass-energy density and pressure, bearing a specific mathematical structure which represents a new solution to the continuity eq…
