In the absence of mathematical explanations, the universe would be irrational rather than unpredictable.
Technology is allowing astronomers to study and analyse galaxies in far more detail than was previously possible.
Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?
Based on what we currently know about the density of giant radio galaxies in the sky, the probability of finding two of them in this region is extremely small.
