Can accelerated expansion of the universe be due to spacetime vorticity?
  We present here a general relativistic mechanism for accelerated cosmic
expansion and the Hubble's constant. It is shown that spacetime vorticity
coupled to the magnetic field density in galaxies causes the galaxies to recede
from one another at a rate equal to the Hubble's constant. We therefore predict
an oscillatory universe, with zero curvature, without assuming violation of
Newtonian gravity at large distances or invoking dark energy/dark matter
hypotheses. The value of the Hubble's constant, along with the scale of
expansion, as well as the high isotropy of CMB radiation are deduced from the
model.
