Last week, SETI Seth Shostak made the claim that we ;ll detect an alien civilization by 2040. Personally, I don ;t believe this will happen for reasons I can elucidate in a future post 鈥?but the Fermi Paradox is definitely a factor, as is the problem of receiving coherent radio signals across stellar distances . But it got me wondering: What, if anything, would change in the trajectory of a civilization development if it had definitive proof that intelligent extraterrestrials ETIs were real Finding a World Much Like Our stanley cup Own As I thought about this, I assumed a scenario with three stanley italia basic elements. First, that humanity would make this historic discovery within the next several years or so. Second, that we wouldn ;t actually make contact with the other civilization just the receipt, say, of a radio transmission 鈥?something like a Lucy Signal that would cue us to their existence . And third, that the ETI in question would be at roughly the same level of technological development as our own so they ;re not too much more advanced than we are; that said, if the signal came from an extreme distance, like hundreds or thousands of light-years away, these aliens would probably have advanced appreciably by now. Or they could be gone altogether, the victims of a self-inflicted disaster . http://io9/5758687/what-it-will-take-for-aliens-to-notice-humanity-aka-the-i-love-lucy-signal I stanley tazza tossed this question over to my friend and colleague Milan Cirkovic Nzwe Two trucks crash and immediately blow up in a terrifying explosion
Mariana Figueiro of the Lighting Research Center at Rensselaer Polytechnic Institute and her team showed that two hours of iPad use at maximum brightness was enough to suppress people normal nighttime release of melatonin, a key hormone in the body clock, or circadian system. Melatonin tells your body that it is night, helping to make you sleepy. If you delay that signal, Figueiro says, you could delay sleep. Other research indicates that if you do that chronically, for many years, it can lead to disruption of the circadian system, sometimes with serious health consequences, she explains.
