Explain what has happened to the number of elements in the universe over time (beginning with the big bang, up to the present day). occurred there big bang when the to present day there are more . So From the , increasing over time and matter made began being more and more elements Bang more was big elements number increased , Now based on your explanation, draw a graph that illustrates the number of elements in the universe as a function of time (beginning with the big bang, up to the present day).
