-- Your comment reminds me of one creationist Freeper who said that time dilation means that the universe is both 6,000 years old and 13 billion at the same time. --

The passage of time is relative, and depends entirely on the observer. To the photon that started it's journey to what us is 13 billion years ago, no time has elapsed at all.

Correct, at least as I understand it.

Time dilation doesn’t change the age of the universe.
