Scene 23:
Megan with Charlie, as he reviews the FBI Techs' findings...

          ...I'd say the killer used some
          kind of "Onion-Routing" technique.
             (off her look)

          a network while staying anonymous.
          Think of it like a sender mailing a
          series of letters inside letters...

Onion Polyhedra

This Demonstration shows polyhedra displayed with layers, like in an onion.
Scene 23:
          You know people in the science
          community, there has to be someone
          you could talk to.

          Larry's NoiseTamper project is an
          NSA initiative, but if NASA's

          spirit is crushed.  He's like... a
          star collapsing in on itself--
          --You two have been hanging out a lot.

Einstein's general theory of relativity gives a completely different picture of gravitation. It is not a force per se, but rather a consequence of the curvature of spacetime. As John Wheeler said, matter tells spacetime how to curve while spacetime tells matter how to move.
