The truth was, when the door to the other dimension shut, Hao Ren knew that his luck had ran out—that turned out to be true. When he returned to Kuiper Station and re-activated the powerful scanning antenna, the solar system did not so much as ping back.
Gungnir's resonant frequency was sent out without receiving any response whatsoever. There was no resonant feedback from the entire solar system.
Back in Kuiper Station's laboraory, Hao Ren watched Gungnir's broken pieces slowly descend on a platform. The equipment around him quieted down as they were turned off. The IDT had checked the numbers and concluded that the alternate dimension had already left the system.
