Andy Albrecht, Joao Magueijo, and John D. Barrow calculate what would have happened if the speed of light had varied in the early moments of the universe’s existence (so-called VSL, or Varying Speed of Light, schemes). If, in the very early moments of the universe’s existence, there had been a brief, temporary decrease in the speed of light, this would have brought the universe close to the boundary between the closed and open universes, the magnetic monopoles would have been eliminated, and the irregularities would have been smoothed out. This is therefore a hypothesis that offers significant advantages in terms of the thesis.
