According to the Big Bang Theory of the Creation of the Universe

Question

According to the big bang theory of the creation of the universe,
A) the universe has been getting cooler since its beginning
B) the initial explosion caused the creation of all of the elements of the periodic table
C) carbon is the most abundant element in the universe
D) the earth could be no older than 1 billion years

Accepted Answer

The Big Bang theory suggests that the universe started from a very hot, dense state and has been cooling as it expands. Initially, only the simplest elements like hydrogen and helium (and trace amounts of lithium) were formed. Heavier elements were created later in stars. Carbon is not the most abundant element; hydrogen is. The age of the Earth, according to scientific estimates, is about 4.5 billion years, much older than the 1 billion years suggested in option D.
