Question

a. The data in the Hubble Diagram can be fit with a straight line. The y-intercept of the straight line is called the Hubble constant (Ho). We know that the normal equation for velocity is v = d + t, where t is the y-intercept of the equation. Therefore, Ho is equal to t. If we could run the Big Bang in reverse, we would see that the nearest galaxies would reach our location first, before the more distant galaxies. In order to use Ho to calculate the true age of the universe, it is necessary to measure distances to the most extremely distant galaxies. This arrival time would then be the age of the universe and could be provided by the Ho. 1000 km/s 500 km's 10 parsec 2 x10 Distance parsec

Explanation / Answer

option b is correct as v=Hd, if d is large v is large also age of universe is 1/H
