The European Space Agency spacecraft Rosetta has rendezvoused with Comet 67P, with plans to send a smaller craft to land on it November 11. The project was launched back in 2004. The comet is about 3×5 kilometers across (1.86×3 miles). Go here for more information. After the jump, photographs from the probe, showing what a comet looks like up close. [Read more…]
DNA evidence may have solved the mystery of Jack the Ripper, the serial killer who brutally murdered 11 prostitutes in Victorian England. A shawl that was reportedly found on the body of one of his victims had blood that has been identified as having come from one of women he killed and semen that has a DNA match with a descendant of one of the original suspects, Aaron Kosminki. But the findings are being challenged. [Read more…]
Sounds are vibrations of the air that are picked up by vibrations of the eardrum. Those vibrations of the air can cause other objects to vibrate. Scientists at MIT have found a way to reconstruct what people have said from a video of the vibrations of a potato chip bag. [Read more…]
Two years ago, the sun blasted out two clouds of plasma. If this had happened one week earlier, they would have hit the earth, knocking out our power grid and doing so much damage that we would still be trying to repair it. [Read more…]
We blogged about how new evidence is casting doubt on the existence of the universe. Scientists have also discovered a massive discrepancy between the amount of light that we can detect and the amount of light produced by galaxies and quasars. The two are off by a factor of some 400%. Put another way, 80% of the light in the universe is missing. This is being called the “missing light crisis.” [Read more…]
Scientists admit that there has been no global warming between 1998 and 2013, even though the amount of greenhouse gases in the atmosphere has continued to increase. A new study claims to account for this so-called “pause” in global warming. It turns out, there are “natural fluctuations” in the climate. Who knew?
The scientists claim that a little cooling blip has cooled things off in the last decade or so, but that the global warming will soon resume. Read about the findings after the jump.
But doesn’t this research miss the point? Does invoking “natural fluctuation” really give us a cause? What causes the fluctuations, and if they are “natural,” might they account for other temperature phenomena, including those blamed on human agency? More fundamentally, if greenhouse gasses can increase without making the temperature of the earth go up, doesn’t that suggest that there may be problems with the assumptions behind the computer modeling that give us the dire global warming forecasts?
