U2 song reference to Sci-Fi novel?

[EnumaElish]

Does anyone think the U2 song "No Line On The Horizon" might be a tribute to Larry Niven's novel Ringworld? The novel describes an engineered, rotating ring-shaped "planet" that occupies an entire orbit around a star. The inside of the ring is populated. Looking afar (e.g. spinward, or anti-spinward) from the inside, the ring appears to curve up toward the horizon, which results in "no line on the horizon."

I've never heard the song, but just looked up the lyrics. They make no sense to me, so I can't really say if they reference anything in particular
