Well the creator is a higher dimensional being - we exist in the 4th dimension which is time i.e.: we have a certain amount of control over the 3 dimensions that we see as X Y and Z, but are 'carried along' by time (that doesn't mean a 5th dimensional being {for example} has control over time and can time travel - same as we can't push a sponge through a lump of lead there are rules), so a higher dimensional being is incomprehensible to us.
Imagine we have created a computer program (2 dimensional) that has say 3 rules; birth death and existence, and it consists of blocks that are 'lit' or not, every cycle (say 1 second) the program updates it decides which blocks are made, which die and which carry on as normal relating to the rules of each point. This has been done and the outcome of running it from various start points is quite extraordinary!! I think it's called 'life' actually but can't remember.
It's perfectly comprehendible that a 'higher' dimensional being has a 'computer' that can have millions of rules input into it - say all the rules of physics that we know, every chemical element interaction etc. This being then inputs some start point variables like certain elements to begin with, and BANG the universe as we know it is created.
So to answer the question, It could be a loop, it could be whatever 'the being that made it' wants it to be. Same as we can simply extend the screen on our computer when the little lit blobs reach the edge, this being can control our universe outer boundary so that we never see or reach it. He could switch off his computer too!!!
