“In fact there’s a fundamental limit to how much of the universe we could ever observe, no matter how advanced our visual instruments.”
“There may be parts of the universe that are farther away…but we can’t see farther than light could travel over the entire age of the universe”
How do you explain that many thousands of galaxies are moving rapidly away from us toward points unseen, seeming to contradict the general expansion of the universe?
