Abstract
If the arrow of time reverses in a recontracting universe it could pro duce observable electromagnetic effects. We argue that the existing ob servational data offer strong evidence against recent versions of time -symmetric universe models, assuming the universe is essentially trans parent on the future light cone. We investigate this assumption for a simple recontracting Friedmann model.
