Get the real life In the article “Scientists get a second life” (SN: 5/24/08, p. 20), I take exception to Joanna Scott’s statement that “Second Life is real life.” In fairness, one could debate what she means by “life,” but the statement is just too strong to ignore. As technical director at a major theater, […]

A little gravity “Britain’s biggest meteorite strike” (SN: 4/12/08, p. 238) states that “gravitational anomalies” make an offshore area a prime candidate as the possible impact site of a meteorite. Wouldn’t that be magnetic anomalies instead? If it is a gravitational anomaly, I would sure like an article on that alone! Thanks for the great […]

Dark star In “From Dark Matter to Light: New models of galaxy formation show the gastro in physics” (SN: 3/22/08, p. 186), Ron Cowen says that gas is where the action is since dark matter predominantly responds to only gravity. Because dark matter responds to gravity, wouldn’t it, like gas, be pulled into the star-making […]

Follow the glow “State of the Universe: Microwave glow powers cosmic insights” (SN: 3/15/08, p. 163) brings up a question. This glow should be stronger in one direction, which can point us to the center of the universe. Is this possible? Donald BurrNovato, Calif. Studies of the microwave glow reveal that Earth is moving surprisingly […]

Why switch to grass? Regarding “Switchgrass may yield biofuel bounty” (SN: 1/19/08, p. 46): Distilleries have been around since the dawn of time, including barleycorn (whiskey), maize (whiskey), potatoes (vodka), sugarcane (rum), and arcane brews distilled from beets, bread crumbs, and bamboo. The ethanol molecule cares not one wit about its particular provenance, so what […]

In this article, Ron Cowen says that gas is where the action is since dark matter predominantly responds to only gravity. Because dark matter responds to gravity, wouldn’t it, like gas, be pulled into the star-making process and become part of the resulting star? Why is our sun not predominantly dark matter?

The price of water In reference to the article “Going Down: Climate change, water use threaten Lake Mead” (SN: 2/23/08, p. 115), scarcity requires society to allocate. Usually markets do a better job than law at allocating efficiently and fairly. Lake Mead could remain full to the brim regardless of pending climate change. The quoted […]
