nAlso called: noodle effect
(Astronomy) physics the theoretical process by which an object approaching a black hole is progressively broken down into a long thin string of particles by increasing gravitational forces, esp the vast difference in gravitational strength at either end of the object
[C20: because the gravitational forces would appear to stretch the object into a long thin string resembling a strand of spaghetti]
