Summary: Imagine looking at red houses, and sometimes you see a crow fly past. But every time you look at a blue house, theres always a crow flying right in front of the house. The crow and the house could be miles apart, so this must be impossible, right? Well, according to a new survey if you look at a quasar, youll see a galaxy in front 25% of the time. But for gamma ray bursts, theres almost always an intervening galaxy. Even though they could be separated by billions of light years. Figure that out. Dr. Jason X. Prochaska, from the University of California, Santa Cruz speaks to me about the strange results theyve found, and what could be the cause.
