Cosmic Engineers by Clifford D. Simak

2.0

This was old-school hard sci-fi, with thin characters. At least it wasn't long.

A pair of reporters are doing a year-long tour of the solar system when they stumble upon a disabled spaceship containing a woman in suspended animation. It turns out that she has been thinking for 1000 years, and understands math/physics that nobody else does. At Pluto, they encounter transmitted thoughts from a far-away civilization, begging for help. This turns into a slog of faster-than-light-travel, multi-universes, time travel, etc.
