Which is not far off of what Hickman was doing with it. But the most important element of it is that conceptual idea. In many ways it is an alternative view of the cosmic concept that in the Marvel Universe is represented by the Cosmic Entities. It is a more fluid and less concrete version, akin to consensus reality. The idea that the universe is partly shaped and changed by the ideas and concepts of those that live there, and that shifts in thinking and understanding are represented as a vast landscape through which planets move.
In newuniversal Earth is heading towards a structural element, in that space, a radical shift in thinking, or paradigm shift. It appears to be such a big change that everything will be different, but something deep is going on. There are suggestions that people are travelling back in time to change events or thinking, this is hinted at being a preparation but might be something more sinister. The other strange thing about the Superflow, it seems to have an artificial element. The huge station like structures that we saw in Hickman as Builder monitoring stations.
There is also a slight flavour of existential horror, akin to The King in Yellow, but that might be just me reading things into it all.
All of this is half remembered and based on comics that never got to fully explain themselves anyway, so it's not to be taken as definitive.
