Take “The Lorentz Invariant.” Go ahead an google it. You’ll find it’s a real concept and deals with time/space. And “Imaginary Space,” I chuckled when I heard it but it turns out to be a staple concept of relativity.
So, the equations and terms were real, what was conspicuously absent, however, is any mention of “course correction.” The problem with putting too much effort into forming any kind of relevant picture from all the high powered name dropping in this episode is that Lost is operating on its own set of rules for time travel. While all the physics may seem to make the mystery deeper, it may be there for the same reason additional leaves are dropped around in a scene, to further the illusion of legitimacy; to facilitate suspension of disbelief.
Are the physics of Lost clues, or just set dressing? Sound off below.
