largest elliptical galaxies are like a spider sitting in its web

Categories: Comparisons

An analogy used to explain a scientific idea:

"The largest ellipticals sit at the centres of clusters today, continuing to grow by absorbing any other galaxy that comes too close, like a spider getting fat by sitting in its web and waiting for food to come its way."

John Gribbin (1996) Companion to the Cosmos. (Ed., Mary Gribbin) Weidenfeld & Nicolson.
