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

                 CHARLIE
          ...I'd say the killer used some
          kind of "Onion-Routing" technique.
             (off her look)
          It's a way of sending content over
          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:
                 MEGAN
          You know people in the science
          community, there has to be someone
          you could talk to.

                 CHARLIE
          Larry's NoiseTamper project is an
          NSA initiative, but if NASA's
          questioning Larry's fitness--
          
                 MEGAN
          --Charlie, Larry's devastated. His
          spirit is crushed.  He's like... a
          star collapsing in on itself--
          
                 CHARLIE
          --You two have been hanging out a lot.

Gravitation versus Curved Spacetime

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.
