A supernova's energy is often compared to the total energy output of the Sun over its lifetime.
Using the Sun's current luminosity, calculate the total solar energy output, assuming a 1010
year main-sequence lifetime.
Using Einstein's formula E = mc? calculate the equivalent amount of mass, expressed in
Earth masses. [Hint: The total energy output of the Sun over its lifetime is given by its current
luminosity times the number of seconds in a year times its ten billion-year lifetime; Week 5
slide 4; mass of earth = 6x1024kg; c = 3x10®m/s. Your answer should be 200-300 Earth
masses.]
