Astronomers have found a black spot that has no stars, no galaxies, no black holes, not even mysterious dark matter, just one billion light years across of nothing.
That is an expanse of nearly six billion trillion miles of emptiness, a University of Minnesota team announced today.
Astronomers have known for many years that there are patches in the universe where nobody is home.
In fact, one such place is practically a neighbour, a mere two million light years away.
