I’m afraid I’m not following that. If light had traveled even faster then than its current speed that would make it even more unlikely that it would still be arriving at our position now rather than having passed by billions of years ago.
I ain’t no cosmologist. Though I can still see that as “everything is at the center of the universe”, as they say, that there are “epochs” which we see into gradually as our powers of magnification become greater.
When we look back 12 billion light-years, I wonder in absolute terms if what we’re seeing is even still extant.
And that it does seem all the more mysterious is part of how God designed it. And it makes me crazy as well.
