According to Einstein’s formula, E=mc^2, the energy radiated away from the Sun (or any star for that matter) represents a loss in mass. That is, every Joule of energy radiated away from the Sun diminishes its mass by m=E/c^2. Assume that the Sun’s luminosity is 3.8X10^26 J/s. a) Determine the amount of mass (in kg) that the Sun would lose by shining at that same luminosity for 10 billion years. b) Sirius A will last about 90 million years as a...
