How long would it take light to travel from the center of the universe to the furthest galaxy?
As of now, it might be 13.8+ billion years.
We are about 27 K light years only, from the center of our galaxy Milky Way. Our scientists have estimated that the the expansion from BB center is not less than 13.8 billion light years, at the speed of light, over 13.8 billion years.
So, in my opinion, the answer to your question is 13.8+ billion years, assuming the possibility that there are some galaxies farther away from center of our universe, beyond our galaxy.
