Particle Decelerator: Sea Above, Sky Below

Sea above, sky below. The phrase is seemingly a contradiction and a mental paradox. Yet recent research into cosmology, astronomy and oceanography suggests that this riddle is perhaps not as irreconcilable as what it may first appear. Recalling Milton’s evocation of the empty heavens as a kind of ocean, the inversion of sea and sky is taking place all around us, in physics and in oceanography.
