I've read that the universe is 13.7 billion years old.
Also, I've read that time passes "slower" when an object is close to a large mass as opposed to an object close to a smaller mass.
Take two galaxies. One galaxy is half the mass of the other. At this moment, has 13.7 billion years passed for both galaxies? Is the heavier galaxy using up its supply of hydrogen slower than the lighter one?
