Inspired by results of Guardo, Van Tuyl and the second author for lines in P3, we develop asymptotic upper bounds for the least degree of a homogeneous form vanishing to order at least m on a union of disjoint r-dimensional planes in Pn for n⩾2r+1. These considerations lead to new conjectures that suggest that the well known conjecture of Nagata for points in P2 is not an exotic statement but rather...
