Orion is one of the most well-known and easily recognized constellations of the winter sky. The three bright blue stars in Orion’s belt seem to draw our attention instantly.1 Such stars are a strong confirmation of the biblical timescale.

Most stars generate energy by the process of nuclear fusion of hydrogen into helium in the stellar core. This is a very efficient power source. Theoretically, a star like the sun has enough hydrogen in its core to keep it burning for ten billion years. But that’s not the case with blue stars.

Blue stars are always more massive than the sun. This means they have more hydrogen available as fuel. Yet, blue stars are much brighter than the sun; some are over 200,000 times brighter!2 They are “burning” their fuel much more quickly than the sun, and therefore cannot last billions of years. Based on their observed luminosity, the most massive blue stars cannot last even one million years before running out of fuel.

None of this is a problem for the biblical timescale of about 6,000 years for the age of the universe. But if the universe were 13.7 billion years old, as secularists allege, then it really shouldn’t have blue stars. Yet blue stars abound in every known spiral galaxy. It seems that these galaxies cannot be even one million years old….
