We see distant objects as they were at the time that light left them. Assuming a Hubble constant, H₀, of 73 km/s/Mpc, what would be the age of the universe? A)13.7 million years B)∞ (infinity) C)13.7 billion years D)47.4 billion years

The age of the universe can be calculated using the formula age = (1/H)*c, where H is the Hubble constant (in units of km/s/Mpc) and c is the speed of light (in km/s). Plugging in the given Hubble constant, we get age = (1/73)*3.0x10^5 = 4.1x10^17 s. Converting this to years (by dividing by the number of seconds per year), we get an age of approximately 13.7 billion years. Therefore, the correct answer is C) 13.7 billion years.
