In cosmology, the Hubble time is the time for us to receive the light of a galaxy that is just about close to move away from us at the speed of light. Currently this is estimated to have a value of to=4.55 x 1017 seconds (or 14.4 billion years). The speed of light is c=299,792,458 m/s. The Hubble distance Do is equal to cto, and it is thought to be largest meaningful unit of length. Using the right number of significant figures, and scientific notation, give the Hubble distance Do in meters by completing the following. The distance is x 10^ meters.
