Textbook Problem

The Big Bang that began the universe is estimated to have released 1068 J of energy. How many stars could half this energy create, assuming the average star's mass is 4.00 × 10 30 kg?

To determine

The number of stars can create half of energy released by Big Bang.

Explanation

Given info:

  • The Big bang release 1068J of energy.
  • The average mass of the star is 4.00×1030kg.

Formula used:

Formula to find the total mass of star is,

  mt=Etc2

Here, Etis the total energy of the stars, cis the speed of light.

As total energy (Et)of star is half of energy released by big bang (E), therefore,

  mt=E2c2      Equation-1

Formula to find the total number of stars.

  N=mtm

Here, mtis the total mass of stars and mis the mass of single star
