The fact is, this curtain of light isthere, but our eyes cannot see it. Due to the expansion of the universe, the wavelengths of these hot, early photons have been stretched over 1,100 times longer than their original wavelengths. The high-energy, luminous backdrop of the early universe, is today filled with relatively cool, microwave photons, invisible to the human eye after being stretched by the expanding fabric of our universe for over 13 billion years.
This curtain is currently being imaged by special detectors, some aboard the Planck Space Telescope, the most powerful microwave telescope ever built. It is giving us detailed views of what was once the brightest ball of energy ever known: the Big Bang.
In the end, Olber was correct. As was Digges, Kepler, Halley and Poe. They troubled over the notion that the night sky should be as bright the noonday Sun, and in fact it is. What they didn't realize was that the night sky is only dark to us. If they had eyes sensitive to microwaves, there would never have been a paradox.
