The gravitational collapse time for the Sun is a constraint on the timescale for the formation of the Solar System: Using the mass of the Sun and a 6.67 X10-11 in S.I. units (m, kg, sec) as the value for G, calculate the gravitational collapse time in millions of years for the mass of the Sun in a nebula with radius 4 light years. Recall that: ????????=√R^3/GM
