In inflationary cosmology, information cannot be transmitted faster than the speed of light (c) despite the exponential expansion of space due to a large positive cosmological constant. Local speeds remain below c, and information cannot travel along spacelike worldlines. However, timelike or lightlike worldlines can exhibit a "coordinate velocity" exceeding c, particularly in rotating reference frames, while still adhering to the principles of special relativity.
PREREQUISITESAstronomers, physicists, and cosmologists interested in the fundamental limits of information transmission in the context of cosmic expansion and relativity.
