This uncertainty1 applies, incidentally, to relatively2 nearby things as much as to the distant edges of the universe. As Donald Goldsmith notes, when astronomers3 say that the galaxy4 M87 is 60 million light-years away, what they really mean ("but do not often stress to the general public") is that it is somewhere between 40 million and 90 million light-years away—not quite the same thing. For the universe at large, matters are naturally magnified. Bearing all that in mind, the best bets these days for the age of the universe seem to be fixed5 on a range of about 12 billion to 13.5 billion years, but we remain a long way from unanimity6.
