Manmade increases in carbon dioxide might be having effects that are larger than expected
In a laboratory in Scotland, a revolutionary kind of laser is taking shape – the first one to be made out of an artificial black hole. Once complete, the device could help confirm mounting evidence that real black holes, despite their name, emit light. A black-hole laser could also find practical uses in devices that…
Late last year, scientists with the OPERA collaboration in Gran Sasso, Italy reported an incredible finding: neutrinos that appeared to be moving faster than the speed of light. In February, the OPERA researchers found a couple small problems with their experimental set-up, calling into question the original faster-than-light neutrino result. The event highlighted the difficulty…
At least four times in the last few years, astronomers have announced they have found planets orbiting other stars in the sweet spot known as the habitable zone — not too hot, not too cold — where water and thus perhaps life are possible. In short, a so-called Goldilocks planet fit to be inhabited by…
Is the universe trying to tell us something?
For those of us who have been intoxicated by the powers and possibilities of mathematics, the mystery isn’t why that fascination developed but why it isn’t universal. How can students not be entranced? So profound are the effects of math for those who have felt them, that you never really become a former mathematician (or…
