Web29 jun. 2024 · The most recent precise measurements of the distances and movements of distant, exploding stars suggest a Hubble constant of 69.8 km/s/Mpc, but other reports have pushed the value as high as 74 km/s/Mpc. Although these differences seem small, even a 2 km/s/Mpc discrepancy between predictions from physics and observations … WebTable 19.1 describes the distance limits and overlap of each method. Each technique described in this chapter builds on at least one other method, forming what many call the cosmic distance ladder.
