Are There Limits to Scientific Speculation?  A Royal Case
May 2, 2010
Question: When does science become like a priesthood?  Answer: When its practitioners engage in speculation on big questions impossible to verify with empirical observations.  Is this what the chief astronomer in Britain is doing?     Sir Martin Rees certainly would not have thought of himself as a priest as he wrote an article for […]

Cosmologist Suffers Paranoid Delusions: Media Promotes His Views
April 26, 2010
“They’re coming to get us, and I’m sure of it, because I know everything.”  What would you think of someone who talked like that?  What if he were one of the most famous cosmologists alive today?  The man is Stephen Hawking – that wheelchair-bound math wizard who talks with a speech synthesizer and once fell […]

SETI and other Pointless Gimmicks
April 15, 2010
Astrobiologist Paul Davies sure knows how to ask interesting questions, and ruffle feathers in the process.  His new book about SETI, The Eerie Silence, reviewed by Leslie Mullen in Astrobiology Magazine, defaced some long-standing notions.  But are his suggestions any improvement?     Davies thinks the Voyager record was a “pointless gimmick.”  He thinks that […]

Conflicting Reports About Earthlike Planets
April 14, 2010
Are earth-like planets rare or common?  Your opinion might depend on which news stories you read.  “Polluted Old Stars Suggest Earth-like Worlds May Be Common,” reported Space.com and Science Daily.  The idea is that hydrogen in the atmospheres of white dwarfs might have come from water, which might be remains of rocky planets that got […]

Venus May Be Hot with Active Volcanoes
April 13, 2010
We already know Venus is hot from its suffocatingly dense atmosphere, but additional heat could be coming from underground.  Results from the European Space Agency’s Venus Express orbiter suggest that volcanoes have erupted any time between now and 2.5 million years ago, a “geologically recent” time compared to the assumed age of the planet (4.5 […]

Evolution as “Scientific Literacy” Dropped by NSB; Sets Off Firestorm
April 11, 2010
Can you be called scientifically literate if you deny that humans evolved from lower animals?  What if you deny the universe began with an explosion?  American students have typically scored low on those questions, leading to charges that they are scientifically illiterate compared to other countries in Europe and Asia.  But now, the National Science […]

You Live in a Wormhole in a Black Hole
April 10, 2010
Is it publish or perish time?  A physicist at Indiana University thinks that “our universe could have itself formed from inside a black hole existing inside another universe.”  Let Nikodem Paplowski explain his idea: But he also notes that since observers can only see the outside of the black hole, the interior cannot be observed […]

The Earth Should Have Frozen
April 3, 2010
According to stellar evolution theory, the earth should have frozen solid four billion years ago, because the young sun could not have put out the heat it does in its middle age.  Called the “faint young sun paradox,” this problem has puzzled scientists for decades.  A new study has failed to solved the puzzle.   […]

Comets Are Cracking Up
March 29, 2010
An amateur astronomer observed a comet splitting in two, reported (PhysOrg), but it’s not just the comets that are breaking up.  Theories about them have undergone a revolution at revelations they are not all they were cracked up to be.  They used to be pristine remnants of the formation of the solar system.  Analysis of […]

Explaining the Undetectable: Science or Faith?
March 28, 2010
Scientists routinely portray themselves superior to religious people who (in their estimation) accept things on faith.  This ignores the fact that many theories in science walk by faith, too.  Theories frequently posit entities that cannot be detected by any means – and may not exist at all, except as props for the consensus.  When a […]

The Whole Universe Is Crazy
March 19, 2010
Suppose you engaged a mental patient about the origin of the universe.  He tells you that it banged and it whooshed and it crunched.  He elaborates and says that there’s lots of universes out there crashing into each other all the time.  “Yep, that’s how it happened, and that’s how we got here.  I’s sure […]

No Clear Explanation for Saturn’s Rings After 6 Years of Cassini
March 19, 2010
Those who hoped Cassini would solve the puzzles of Saturn’s rings should read the paper today in Science.1  The state-of-the-rings report, authored by a Who’s Who of ring scientists, is filled with questions.  Titled “An Evolving View of Saturn’s Dynamic Rings,” the report cannot determine their origin, their age, or their composition.  List the points […]

Search for Intraterrestrial Life Scores Big
March 16, 2010
Single-celled organisms may be tiny, but what they lack in bulk they make up for in volume and importance.  Scientists have been appreciating more than ever the ubiquitous presence of microbes on our planet and the roles they play to sustain the biosphere.     PhysOrg reported that half of the world’s life may lie […]

Mars Discoveries Change Paradigms
March 15, 2010
Mars is under assault by an armada of orbiters gathering intell from the planet with photons and radar beams.  What kind of information has been seized recently? Dry rivers:  Remember the networks of river channels that were telltale signs of water?  Remember the hope for life those images generated?  Some of those riverbeds could have […]
