/article/light-distance-problem
David F. Coppedge - Perhaps the question most often asked of Biblical creationists is how light from distant stars could get to the earth in a few thousand years. People usually want a quick one-sentence answer to this question, but to discuss it fairly would require...

/article/supernova-shell-shock
David F. Coppedge - They had told us a particular supernova exploded 10,000 years ago. How then, did the Chinese see it in AD 185? The answer is a case study in scientific inference. Supernova remnants (SNRs) are shells of material expanding outward from stellar...

Habitable Zones - Apr 1, 2007
/article/habitable-zones
David F. Coppedge - When speculating about life in the universe, scientists need to be more realistic than Hollywood. In Star Trek, no matter where the actors land, they can walk around and breathe the air. That may be easier on directors, but for a surface to be...

/article/space-travel-shields-up
David F. Coppedge - In this unique era of human history, manned space flight -- the dream of many a novelist -- has become routine. Star Trek and its spin-offs have taken our imaginations far beyond our giant leap to the moon. Is the sky the limit? Most manned space...

David F. Coppedge - Dating methods are like human pyramids; they depend ultimately on the support of the bottom layer. Picture an inverted pyramid. If the bottom guy buckles under pressure, the circus act quickly turns into a dogpile. One widely used technique for...

/article/theres-only-one-universe
David F. Coppedge - Recently a new word has appeared in cosmological literature: multiverse. You won't find it in the dictionary, because it contains a contradiction in terms: multiple universes. By definition, the universe is supposed to include everything. One...

/article/enceladus-cold-youthful-moon
David F. Coppedge - One year ago, one of the most startling discoveries in the history of solar system exploration was announced. One of Saturn's little moons, Enceladus, less wide than Arizona erupted and continues erupting. Plumes had been suspected months...

/article/mature-at-birth-universe-discredits-evolution
David F. Coppedge - Critics of recent creation ridicule the belief that a universe so vast, composed of so many diverse phenomena and processes running at diverse rates, could be fit into a few thousand years. They are less likely to acknowledge the many and severe...

/article/seti-design-spite-itself
David F. Coppedge - Researchers involved in the Search for Extraterrestrial Intelligence (SETI) use scientific equipment, collaborate with scientists, attend scientific conferences, publish scientific articles, and generally look and smell like scientists, lab coats...
