Which of the following is NOT one of the three observations that support the big bang theory?

• Scientists have detected cosmic background radiation that is believed to be a direct remnant of the Big Bang theory.
• The Big Bang theory predicts that the universe should contain about 75% hydrogen and 25% helium and scientists have determined that is the actual abundance of these two elements.
• The size of the Milky Way Galaxy has been determined to be the approximate size that it would have been if the Big Bang theory explanation had occurred.
• Measurements of the light from stars show a shift to the red portion of the spectrum implying they are moving farther away from Earth. This shows the galaxy is expanding.
