| Hubble's original value for "his" constant was 500-550 km s-1 Mpc-1, as opposed to our current estimate of 71 ± 4 km s-1 Mpc-1. | |
| Explain why Hubble's value, taken in combination with other information available in the 1940s, favours the Steady State cosmological model. | [2] |
| Briefly describe the two main errors in Hubble's distance determinations which led to this erroneous result. | [3] |
