How do Hurley and Sayid intercept the radio signal and hear that old 1940’s music?
There could be a few explanations of this. Sayid had mentioned that the radio waves could be bouncing off the ionosphere (the metallic layer in the sky), and Hurley suggests that it could be from a different time. In one sense, a radio signal could’ve came from the year 1940, entered the magnetic bubble that encompasses the island, and it’s been bouncing off the bubble’s magnetic field for decades. On the other hand, if the island is existing in 1996, then Sayid may actually be intercepting a radio transmission from the year 1996.
