It is an awesome idea. I'm embarrassed that it didn't actually occur to me independently. I know, that's what makes it so striking. As soon as you hear it, it makes total sense and you wonder why you didn't think of it yourself.

But, over the course of their billions of years in transit to us, the space they inhabit along their path through the stars has grown more than 1000 times bigger since they were born. Some theorists think the 13.7 billion year old universe is 156 billion light years wide, which seems impossible. Nothing in reality is infinite so either the universe has an edge where light bounces back, or light curves until it starts heading back.
