Päikesetorm võib külvata laialdast hävingut
Steve Connor vahendab Independentis ekspertide hoiatusi, mille kohaselt oleme me unest ärkava Päikese tormide ees suhteliselt kaitsetud ning meie haavatavast tehnoloogiast kubiseva maailma hoiatamine sõltub ühest 14 aasta vanusest satelliidist.
A 14-year-old early-warning satellite is the only way of directly detecting the potential magnitude of the danger this wave of charge particles within a solar storm poses to pipelines and electronic systems on Earth, he said. "Any storm coming from the Sun has to pass over that spacecraft before it hits Earth. If it takes 20 hours to go from the Sun to Earth, it's going to take about 20 minutes to go from that spacecraft to Earth. So our last warning is a 20-minute warning, which will tell us how big, how strong, how nasty that storm might be," he told the meeting.

Surematus ja tehnoloogiline singulaarsus
Lev Grossman kirjutab Time'is tehnoloogilisest singulaarsusest, Raymond Kurzweilist ja inimeste varem või hiljem saabuvast surematusest.
The difficult thing to keep sight of when you're talking about the Singularity is that even though it sounds like science fiction, it isn't, no more than a weather forecast is science fiction. It's not a fringe idea; it's a serious hypothesis about the future of life on Earth. There's an intellectual gag reflex that kicks in anytime you try to swallow an idea that involves super-intelligent immortal cyborgs, but suppress it if you can, because while the Singularity appears to be, on the face of it, preposterous, it's an idea that rewards sober, careful evaluation.
