Electrodynamics of a Dark Fluid: Unlighted Cosmological Epochs as Black Hole Analogues


Presenting author: Alexander Balakin

Intervals of the cosmological time, for which the square of an effective refraction index is negative, were indicated in [1-3] as Unlighted (Dark) Epochs in the Universe history, since during these epochs electromagnetic waves can not propagate. The start of such epoch is characterized by vanishing group velocity of the electromagnetic waves, thus, the electromagnetic energy-information transfer stops. In the planned talk we discuss the analogy between the Nonminimal Black Holes and the Dark Epochs in the context of light behavior. [1] A.B. Balakin, V.V. Bochkarev, J.P.S. Lemos. Phys. Rev.
