https://www.chronocompendium.com/Term/Time_Error.htmlThis is notes on the theories of Chrono Trigger's 'end of time' area. It's basic guess at Chrono Trigger physics is that the end of time was a vantage point, and the science-fiction explanation was that maybe there was a timeline along another axis, so to speak.
Stephen Hawking, love or hate him, has discussed a similar theory.

But when you look into it hes talking about a non parallel timeline, like if the big bang didnt 'start' time, then the timeline 'bent' so his theory goes on. In other words, If time travel were real and one could travel back more than 15 billion years ago along this 'bent' timeline, then you could watch the actual big bang and various points of time. Though he goes on to mention that this so dubbed big bang was basically physical and time always existed. Interesting read.
taken from the article -
"Quantum theory introduces a new idea, that of imaginary time. Imaginary time may sound like science fiction, and it has been brought into Doctor Who. But nevertheless, it is a genuine scientific concept. One can picture it in the following way. One can think of ordinary, real, time as a horizontal line. On the left, one has the past, and on the right, the future. But there’s another kind of time in the vertical direction. This is called imaginary time, because it is not the kind of time we normally experience. But in a sense, it is just as real as what we call real time.”
