This article mainly considers the blow up phenomenon of the solution to the wave-hartree equation utt − Δu = (|x|−4 * |u|2)u in the energy space for high dimensions d ≥ 5. The main result of this article is that: if the initial data (u0, u1) satisfy the conditions E(u0, u1) < E(W, 0) and \(\parallel\triangledown{u_0}\parallel_2^2>\parallel\triangledown{W}\parallel_2^2\) for some ground state W, then the corresponding solution must blows up in finite time.
