Abstract: I will discuss a topology based on CPT and two principles: (1) No boundaries to space-time (2) no physical infinities (or singularities). Consequencies are that world-line time (as in Feynman diagrams) is a closed loop with no beginning or end, different from thermodynamic or psychological time which is transient, not relevant at the Big Bang or in deep time (longer than the proton lifetime). The antimatter is in a “parallel anti-Universe” connected to ours only at the beginning of inflation and in deep time, avoiding the need for a “grand annihilation”. The visible part of the universe is a tiny fraction of the whole and so appears flat. The total energy of the universe must be zero, inflation cannot be eternal, but a multiverse with different physical parameters (broken symmetries) is natural.
