Radio waves are not sound waves, but they are still electromagnetic waves, situated on the low-frequency end of the light spectrum.
Many objects in the universe, including stars and quasars, emit radio waves. Even our home galaxy, the Milky Way, emits a static hiss (first detected in 1931 by physicist Karl Jansky). Other galaxies also send out a background radio hiss.
But the newly detected signal, described here today at the 213th meeting of the American Astronomical Society, is far louder than astronomers expected.
There is "something new and interesting going on in the universe," said Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md.A team led by Kogut detected the signal with a balloon-borne instrument named ARCADE (Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission).
In July 2006, the instrument was launched from NASA's Columbia Scientific Balloon Facility in Palestine, Texas, and reached an altitude of about 120,000 feet (36,500 meters), where the atmosphere thins into the vacuum of space.
ARCADE's mission was to search the sky for faint signs of heat from the first generation of stars, but instead they heard a roar from the distant reaches of the universe."The universe really threw us a curve," Kogut said. "Instead of the faint signal we hoped to find, here was this booming noise six times louder than anyone had predicted."
Detailed analysis of the signal ruled out primordial stars or any known radio sources, including gas in the outermost halo of our own galaxy.
Other radio galaxies also can't account for the noise — there just aren't enough of them.Source: FoxNews: http://www.foxnews.com/story/0,2933,477880,00.html
2 Corinthians 12:2-4
"I know a man in Christ who fourteen years ago--whether in the body I do not know, or out of the body I do not know, God knows--such a man was caught up to the third heaven. And I know how such a man--whether in the body or apart from the body I do not know, God knows-- was caught up into Paradise and heard inexpressible words, which a man is not permitted to speak."
Whether Paul was physically taken to heaven or it was shown him, even he could not say for sure; however, it's clear from this passage that he went to the place where the Lord resides, the third heaven. The first heaven is regarded by theologians as our earthly atmosphere, the second heaven: outerspace, and the third heaven as God's habitation. A paradise! I pray to see you there!
