Infrared (IR) is a portion of invisible spectrum: the portion of the invisible electromagnetic spectrum consisting of radiation with wavelengths in the range 750 nm () to 1 mm (), between light and radio waves (1). Infrared light was discovered in 1800 by Sir Frederick William Herschel (2). In the last several decades the use of IR cameras and goggles for military, police and civilian purposes has grown. Since our human senses are not capable of perceiving IR light we didn’t even know about it for centuries. Does this mean that IR light didn’t exist prior to 1800? Of course not! We just couldn’t see it. However, this is precisely what skeptics say about the spiritual world; that because we can’t see it, it doesn’t exist. What if the spiritual world like, IR light prior to 1800, exists but we just don’t the means to see it via our senses or current technology?

The Greatest Question
Adam Frank in his blog post entitled "Life Is More Meaningful Than Mere Facts Can Convey" quoted Jean-Paul Sartre, ‘"Even if God did exist, that would change nothing."’ Adam’s point is that knowing whether God exists or not is irrelevant because life is about being. I disagree because knowing whether or not God exists determines the meaning of our lives. If God doesn’t exist then there is no objective meaning to our lives.
The philosopher, Arthur Schopenhauer wrote, “We can regard our life as a uselessly disturbing episode in the blissful repose of nothingness.” If God doesn’t exist then Schopenhauer is right, our lives are essentially meaningless. Since the material world is composed of parts it will eventually be torn apart via the second law of thermodynamics. Our bodies break down as we age making our lives ephemeral. Our own sun that makes life on earth possible is slowly dying. One day the sun will run out of fuel causing it to turn into a red giant. It will eventually expand and scorch the earth before contracting and going cold. The universe too is slowly dying. The universe is expanding at an increasingly fast rate so it is growing colder and darker. Eventually all the fuel in the universe will be used up and all the stars will die causing the universe to be extremely cold—all life would have been long extinguished. This means that all our memories and work in the physical world are doomed as well. Sadly, even the great works of Shakespeare, Plato, Tolstoy, Beethoven, Mozart, Da Vinci and Picasso will be destroyed. If there is no God then the world and humanity are like sandcastles built on the edge of the seashore and the great wave of time is poised to come crashing down.
