Is it not Impossible to predict the age of Universe?

Now we say that the farthest point in our observable universe is 13~14 billion years.now say, I am teleported to that 13 billion light year far point instantly, and then try to see the point which was just as much old and far, but in the opposite direction, we would see our earth and that point in one line. No the... show more Now we say that the farthest point in our observable universe is 13~14 billion years.now say, I am teleported to that 13 billion light year far point instantly, and then try to see the point which was just as much old and far, but in the opposite direction, we would see our earth and that point in one line. No the distance from the point where i am, say x is 13 billion light years and i am seeing that another opposite point say y which is also 13 billion light years from earth, i will find that point y is about 26 Billion light years from there. That means is Universe 26 light years old there?!? Or is it 13 or less than a billion??!!??
