2015 alien news4/5/2023 ![]() ![]() Seth Shostak is the Senior Astronomer and Director, Center for SETI Research, in Mountain View, California, which searches for extraterrestrial intelligence. As Colombano points out, if there’s something to be discovered, we won’t find it unless we look. Maybe there’s a gold nugget in all those reports. So Colombano suggests that massive computers be applied to finding such evidence among the many thousands of UFO sightings. Bright ideas are nice, but evidence rules. Of course, a scientist would consider such a suggestion of interest only if it could be corroborated by observation. This might have happened 100 million years ago or a billion years ago, and we wouldn’t know.īut the more appealing thought for many people is that we’re being visited now. So, what should we conclude? Clearly, it’s possible that some alien intelligence has decided to come to our solar system and check Earth off its bucket list. Compact machines wouldn’t take much space, and wouldn’t groan at the long transit time. If the passengers don’t mind spending billions of years in a middle seat, they could to it. Even at the modest speed of a NASA rocket, that’s more than enough time to get to our planet from anywhere in the Milky Way Galaxy. Earth has been trundling ‘round the Sun for more than four billion years. Consequently, they can go great distances, simply because they’re in no hurry to get to their destination. Well, an obvious advantage of non-carbon machinery is that it needn’t be cursed with a short lifetime (this despite the experience you may have had with your laptop.) Truly sophisticated devices can be self-repairing. Since most star systems are billions of years older than our own, you can be sure that any clever inhabitants out there have long ago relegated biological brains to the history books, and are homes to very smart, and possibly very compact, thinking hardware.Īs Colombano notes, “Given the fairly common presence of elements that might be involved in the origin of life … it is a reasonable assumption that life ‘as we know it’ was at least a common starting point, but our form of life and intelligence may just be a tiny first step in a continuing evolution that may well produce forms of intelligence that are far superior to our and no longer based on carbon ‘machinery.” By the end of this century, it’s possible that the smartest thing on Earth will be a machine. Anyone who’s not a total troglodyte knows that artificial intelligence is on the way. However, there’s a fix for that: Get rid of intelligence that dies. This small problem, after all, was the motive for Star Trek’s (fictional) warp drive. Namely, that the aliens are biological, and require a fast transit between star systems to forestall dying en route. Their home planet, wherever it might be, is just too far away.īut there’s an assumption here, as Colombano points out. So forget the idea of little gray guys piloting saucers in our airspace. ![]() Fast travel between the stars is incredibly difficult (or impossible), she’ll say. The energy required to accelerate an Enterprise-size starship to near the speed of light is greater than can be wrung from all the remaining fossil fuel on Earth. ![]() He cites this example: If you approach your favorite astronomy prof and see what she has to say about interstellar rocketry, the chances are she’ll roll her eyeballs. They could be throwing the infant out with the bath water. Colombano says that the skeptical attitudes of most researchers might be too cramped. He was a presenter at a conference about new approaches in the search for extraterrestrial intelligence (SETI) held earlier this year at the SETI Institute in Mountain View, California. That scientist is Silvano Colombano, a computer expert and roboticist at NASA’s Ames Research Center in the heart of the Silicon Valley.
