There could be an edge, but it's definitely not within the distance we can see out. The main mind-bender is that there's no need for an edge.

Well, not really. The distance we can see out is measured in time and we can very nearly see the Big Bang. We can observe the Universe's Recombination event and it is in every direction we look as the Cosmic Microwave Background. This happened everywhere in existence.

If there is an edge to the Universe it is in the fourth dimension when the Universe was a singularity.
