This was a really good SciFi series with all its inventions and of course the stories of the inhabitants. But when the nonsense with the time travel came, the end of the series was marked. In an annihilating universe there is no possibility to travel to a living past or nothing can come from the future. There are not even theories for it. All existing 'time travels' refer to the relative time according to Mileva Maric. That is something completely different than epochal time.
