Okabe agrees to let Kurisu look at the mobile microwave on the condition she become a lab member. They discover that Daru was using the microwave at the time Okabe sent his text about Kurisu's stabbing. Okabe concludes that the mobile microwave is, in fact, a time machine which sent his message into the past. After hearing about the large hadron collider and micro-black-holes, Okabe asks Daru to hack into SERN's network. There, they discover SERN had already been performing top secret micro-black-hole experiments, during which humans had died.
