If they haven’t addressed it, that’s because they haven’t thought thru the consequences of their assertions. If we see a star that’s a million light years away, then the light must have travelled a million light years which takes a million years, therefore the universe must be no less than a million years old; faced with this, they usually fall back on the “light in flight” argument which even CRI recommends against as designating God a deceiver.
“If they haven’t addressed it, that’s because they haven’t thought thru the consequences of their assertions.”
Certainly they have, which is why there are other proposals to explain the “light problem”, like I said.
