Today's Creation Moment

The Sixty-Seventh Book of the Bible

"For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that...
As we all know, there are 66 books in the Bible – no more, no less. And yet, from the way that many people interpret the first chapter of Genesis, it appears that they have added a sixty-seventh book...

The Light-Emitting Swallowtail

Genesis 1:3
And God said, ‘Let there be light;’ and there was light.

Though tiny, the scales of the swallowtail butterfly's wing are similar in design to light-emitting diodes. We say similar because the design is closer to a specialized light-emitting diode that puts out six times as much light as a standard LED.

The blue-green wing of the swallowtail is covered with millions of tiny scales. Each microscopic scale has three layers. The top layer is made up of thousands of hollow cylinders shaped in a honeycomb pattern. There is fluorescent pigment within the sides of those cells. The second layer adds the blue-green color to entering light and the bottom layer reflects it back out. As the light enters, the top layer focuses and reflects all the blue-green light that enters it. The second layer turns any other color entering light – including ultraviolet light – blue-green, and the bottom layer reflects it back out.

The efficiency of the delicate structure has been compared to LEDs that have two-dimensional photonic crystals that put out six times as much light as a regular LED. As one scientist put it, they had no idea that the design would be so "precise" and "refined."

Of course it's precise and refined, showing an understanding of light! It was designed by the same Creator Who created light in the first place.

Thank You, Father, for creating light with its beauty and especially for the beauty of the light of the Gospel. Amen.
