The clusters are caused by collisions, triggered by the shaking, says Stéphan Fauve of the Ecole Normale Supérieure in Paris.
Astronomers have detected clusters of stars, which flare to life as shock waves of collisions trigger clouds of gas to collapse into new stars.
By any measure, the once "enduring" U.S. - Saudi alliance is on a collision course, triggered by a fateful election year reckoning long overdue of the costs and benefits to a "friendship" that strains the credibility of that word.
The last mass extinction occurred some 66 million years ago, when a meteorite collision probably triggered the extinction of the non-avian dinosaurs and other large reptiles, but spared small animals such as mammals, which then resembled shrews.

Collision-induced dissociation was triggered by rolling collision energy (Supplementary Table 1).
The system is meant to prevent collisions by triggering an alarm if two trains are on the same stretch of track, and was introduced across the German rail network after two trains crashed in Saxony Anhalt in January 2011, killing 10. "It should automatically prevent train collisions by forcing the trains to brake," Dobrindt said.
Such collisions could trigger the clouds to collapse and spawn new stars.
The purpose, quoth ALMA, is to "understand how galaxy collisions can trigger the birth of new stars".
Dissolution of a bond again may be a time-triggered reaction or triggered by collision with another, non-bound entity.
Dr Rampino observed some time ago that collisions might be triggered by gravitational disruptions of the Oort cloud, a repository of comets in the outermost part of the solar system.
