Astronomers believe that
the biggest stars in the Galaxy may be a hundred times more massive
than the Sun, but are a million times brighter. Would you expect such
stars to have longer, shorter or comparable lifetimes to that of the Sun?
Science need help -
Shorter. To be a million times brighter than the sun, they must consume fuel (hydrogen and helium)a million times faster. But they only have 100 times more fuel than the sun; so they only last 10^2/10^6 = 10^-4 as long as the sun before blowing up and burning out
