كبلر........ يكتشف وجود كواكب..... شبيهة بالارض

Quote: But note that when scientists talk about life they are refereeing to life as we know it, that is, carbon-based and operating in an aqueous medium. Other types (such as silicon-based and using ammonia as solvent), even if interesting, are probably more fiction than reality, although some speculations are quite unsettling: intelligent life could have evolved so beyond what we can conceive that it reached a stage where it could leave behind its carbon envelope, existing in some sort of ethereal digital web sustained by electromagnetic fields, that is, a life without a narrow spatial confine or a biochemical ####bolism. Who knows?
