Explanation:
By using Einstein equation,
E = mc²
m = E/c²
As the sun's energy output remains constant, we are taking it as 3.839×10²⁶.
speed of light c = 299,729,458 m/s
by putting these values in above equation,
m = (3.839×10²⁶)/(299.729,458)²
m = 4.721×10⁹kg.
It is the mass that loss per second.
Now a year (including leap year) has 31,556,926 seconds. Thus the 10 billion years equal 1.348×10²⁷kg of total mass loss.
