I agree that time travel is a possiblity (anything is a possiblity in a sci-fi universe), however the chances of this are very remote.
The gateway structure on Earth is what's sustaining the portal - that and the pylons of the Ark. Just like a tornado, in order for it to work, both sides must remain open. If one side collapses, the other side won't have enough energy to continue until the side that collapsed regains its energy - in which case, the Ark could not because of the firing of the Halo destroyed it. It's possible that the chief's half of the ship made it as the portal collapsed around them, and as the ship broke away, with Arbiters side making it back to Earth, Chief's half could have accelerated to who knows what side of the galaxy. Even in the Halo Universe, Slipspace was still very unpredictable.
