|"The most commonly accepted time scale for the removal of this much dust is in the hundreds of thousands of years, sometimes millions"... This warm dust is thought to be the raw material from which planets form, but scientists don't have a clear understanding of how long the process takes... The researchers explored several different explanations for how such a large quantity of dust could disappear so rapidly, and each of their explanations challenges conventional thinking about planet formation... "If what we observed is related to runaway growth, then our finding suggests that planet formation is very fast and very efficient," Song said. "The implication is that if the conditions are right around a star, planet formation can be nearly instantaneous from astronomical perspective."|
