Antichronos, a plea for a symmetric Big Bang
by
Marcel Guenin, University of Geneva
What happened at time zero of the Big Bang is obviously speculative in many aspects, yet some of these speculations could be linked to some features of our world.
The starting point of this note is to suppose a symmetry of time, that means the Big Bang consisting in the simultaneous creation of a positive time (ours), and a negative one, each one with its space and matter. Twin universes in fact, mirrors of each other.
The question we ask is whether it is possible to impose conservation laws leading to constraints in the structure of our world.
We take one example. The conservation of fermions. For one fermion in our world, we will have one anti- fermion in the symmetrical world. Stueckelberg and Feynman have shown that an anti-fermion behaves exactly as a fermion with negative energy and opposite charge. The total energy and the total charge are zero for our example, and this model predicts the domination of ordinary matter, but with many
hypothesis of course.
To play with the other forms of energy, like vacuum energy or kinetic are not as easy, but the complexity of the system could be fun, and the philosophical implications of this concept of time be interesting.
