What could be past the 93 bilon light years we know of?

We don’t know.
Since the universe isn’t infinitely old, there has only been so much time for light to physically travel. This limits the distance you can see, and thus limits you to a sphere of “observable universe” that has been close enough for long enough that light can reach earth.
It’s not really possible from our vantage point to know what’s beyond the “edge” of what we can observe.
