For comparison, WASP-18b's infall timescale is an order of magnitude shorter than that of the much-discussed OGLE-TR-56b6, 7 (assuming that Q is the same for both), and gives a current rate of period change of â"0.00073 (106/Q) s/yr. For low values of Q this would accumulate to a detectable change in transit epoch in less than a decade (for Q = 106 the transit time shifts by 28 s after 10 yr, which compares with a currently achievable timing accuracy of 5 s). Thus WASP-18b is a diagnostic planet, either (for a low Q) being an exceptionally rare object in which the tidal decay is directly measurable, or forcing a reappraisal to much higher Q values; either way it will help establish the dynamical ages of the class of hot-Jupiter planets. WASP-18 will also help constrain our understanding of stellar interiors, given that the Q value depends on the dissipation of interior waves excited by the tidal forcing.
So if the orbit is decaying, we'll be able to measure it in 10 years, otherwise there will be useful data to refine theories about tidal forces in the surfaces of stars.
Intelligent design and (young earth) creationism are in general rather distinct, although the rather large differences are sometimes blurred both by proponents trying to gather support and by opponents who want to simply ridicule both groups instead of trying to reason with them. In order to argue effectively against either of them, you must first identify which of the viewpoints the other party is proposing. Otherwise you just end up talking past one another, which is OK for scoring points with the peanut gallery but does nothing to advance the debate.
(I guess someone will argue that there is no point reasoning with either group. However, in any public forum there will often be someone who is prepared to listen to a carefully constructed argument. On the other hand, this is the internet.)
