SANTIAGO, Chile -- Wearing a rainbow skirt, silver face paint and a pair of metallic radio dishes on her head, Constanza Biagini was an exhibit unto herself. She stood in a dim back room of a crowded Chilean subway station, a living interpretation of the country's newest point of astronomical pride. And then she started singing.
Her performance served as a formal introduction to ALMA, the Atacama Large Millimeter/sub-millimeter Array, the largest telescope ever built on Earth. The most powerful observatory in short-wavelength radio astronomy, ALMA is a feat of engineering that will unveil cosmic histories, like the birth of stars and planets, that have until now been invisible to us. It's also an enormous source of pride in Chile, where people like to say they have the best skies for astronomy.
Morning commuters passing through Estacion Baquedano heard a soaring, operatic vocal performance that trilled like radio waves, or at least otherworldly sounds that you might associate with radio astronomy. Remember the opera scene in the movie "The Fifth Element?" That's what this was. Biagini, 26, said she tried to emulate the sounds of a theremin.
ALMA is an array of 66 radio dishes situated in the Atacama Desert, the driest place on Earth, which provides spectacular views for both human eyes and finely tuned radio receivers. Though it is hosted by Chile, it is very much an international collaboration--the U.S. and Europe donated 25 dishes each, and the remaining 16 were built by Japan. It is formally inaugurated today, and I am here with dignitaries from all over the globe who are celebrating ALMA's potential to transform astronomy. Stay tuned for much more.

SCIENCE SHOWS THE UNIVERSE CANNOT BE ETERNAL because it could not have sustained itself eternally due to the law of entropy (increasing energy decay, even in an open system). Einstein confirmed that space, matter, and time all had a beginning. Even time had a beginning! Time is not eternal. Popular evolutionary scientist Stephen Hawking admits that the universe came from nothing but he believes that nothing became something by a natural process yet to be discovered. That's not rational thinking at all, and it also would be making the effect greater than its cause to say that nothing created something. The beginning had to be of supernatural origin because natural laws and processes do not have the ability to bring something into existence from nothing. The supernatural cannot be proved by science but science points to a supernatural intelligence for the origin and order of the universe. Where did God come from? God, being infinite, didn't need a beginning or cause, and God is not under the law of entropy. Read my Internet article: HOW FORENSIC SCIENCE REFUTES ATHEISM
