Some astronomers have theorized that galaxies (matter) and antigalaxies (antimatter) have existed. Each galaxy contains about 1011 masses of the Sun. Calculate the total energy released if a matter-antimatter galaxy pair annihilated. The mass of the Sun is 1.9 × 1030 kg and the speed of light is 3 × 108 m/s. 1. 3.42e+58 2. 3.42e+58 3. 3.42e+58 4. 3.42e+58 5. 3.42e+58 6. 3.42e+58 7. 3.42e+58 8. 3.42e+58 9. 3.42e+58 10. 3.42e+58 Answer in units of J.
