Abstract
We study the behavior of spiky features in Gowdy spacetimes. Spikes with a velocity initially high are, generally, driven to a low velocity. Let n be any integer greater than or equal to 1. If the initial velocity of an upward pointing spike is between and the spike persists with a final velocity between 1 and 2, while if the initial velocity is between and the spiky feature eventually disappears. For downward pointing spikes the analogous rule is that spikes with an initial velocity between and persist with a final velocity between 0 and 1, while spikes with an initial velocity between and eventually disappear.
