Ask Slashdot: What Is Your View On UFO Sightings?

dryriver writes: UFOs sightings have been reported in the tens of thousands over the last decades. In the past, some have seen flying cigar-shaped craft (blimps?), some flying triangles, some more rounded-looking flying saucers. Often the apparent spacecraft does something improbable like standing completely still in the sky and then shooting off to somewhere at an incredible speed. Some sightings are just lights or light formations flying around or dancing around in the night sky -- which could be military aircraft like helicopters and F16s training at night. There seem to be people who genuinely see stuff that is hard to explain, people who fake UFO sightings, photos and videos for profit to keep the "UFO industry" of websites, radio shows and magazines afloat, and yet others that think a regular airplane flying at night with its lights on is a UFO. What is your view on all this? Are we being visited from outer space? Is it prototype aircraft that look like UFOs to the untrained eye? Was some 190 IQ inventor-prankster having fun with quadcopter drones with colored lights four decades before quadcopters became a thing (hey, tons of people have created fake crop-circles in the past)? Where do all these supposed UFO sightings and reports come from? Did events like the famous "Battle Of Los Angeles" actually happen? And do you find any UFO reports credible at all?

      Funny you should bring up religion. There is actually a lot of current thought that these are actually the same phenomenon. Historical sightings of angels, saints, and miracles often have the same descriptions that more modern UFO sightings have: disks and sphere flying through the sky, often described as moving in a tumbling or skipping motion, bright lights, and even abductions with transport to another place or missing time. From there, you get into different camps as to what is going on. Either people of old mistook aliens visitations for angelic beings, or mistaking supernatural creatures as aliens. If you look up "aliester crowley lam" you'll get a picture of the spirit he is said to have contacted though magic ritual in 1918 and you'll see a pretty classic alien grey type figure with large head and almond eyes. Then you have others that say that this is just a bit of human psychology and people are seeing things but just adding in their own interpretations to them that match their current belief system. Then their are those who suggest the choice is not one of actually being visited by something or delusions, but options for anything in between.

Every now and then a legend is confirmed real, but sometimes is debunked (Loch Ness monster.)

They've lost credibility as a trope in media, having been replaced by Zombies and Vampires, who more closely resemble our current cultural anxieties. Xenophobia led to broad fear of space aliens, and the cold war Red Scare led to general fear of invasion. The fall of the USSR was accompanied by a shift in anxieties to fear of the internal moral collapse of one's society. Vampires represent the hidden minority slowly corrupting society, whereas Zombies represent a foolish majority clamoring for society's downfall.

Being an ultralight and RC pilot, I'm well aware that "standing still" can be when the object is moving toward or away from you, but I couldn't explain the maneuvers this thing was doing. It was night, a light in the sky moving in ways that planes don't. The four or five people watching it were confused and a little bit amazed.

    The whole incident demonstrated several scientific principles. A point of light against the dark sky could be 10 miles away and moving at 1,000 MPH or 300 feet away and moving at 1MPH - your eyes cannot tell the difference. (I don't feel like doing the math to convert arc seconds to MPH, but you get the point). Stereopsis isn't very effective after a hundred feet or so and and stops working at all at a distance of several hundred feet. We thought it was large object, far away moving fast.

SAC had every border lit up with radar that was being watched continuously for "unidentified flying objects" that without question would have been interpreted as an attack by the USSR, not visitation by snoopy space aliens. Every commercial airport was equipped with radar and flight control, (and still is today) and any object not identified by procedure and law would be immediately detected and in all probability investigated, especially post-9/11.

The alien stealth has to be almost perfect to hide from civilian radar, or civilian radar has to be part of the conspiracy (which by now has grown to include the entire air force, NASA, the top levels of every government, all of the major intelligence and police services -- worldwide). AND we need psychotic aliens because REAL aliens intent on invasion would have crafted a killer virus long before now and collapsed civilization or would have just fired a few nukes at Russia and the US simultaneously and than sat back snacking on popcorn while we collapsed it for ourselves and left them some simply mopping up to do before they took over the rest of the world without credible opposition, and REAL aliens interested in making friend would have made friends long ago.

    While not impossible, that seems unlikely - both technologically and economically. Even we have (expensively) already mastered alchemy. We have the tech to create matter from energy. Imagine that tech in a few hundred years. What would be cheaper and better -- making stuff at home or building a fleet of galactic warships and sending them (along with thousands of soldiers and miners) to some far off planet?

    Currently, we're not even able to get to Proxima Centauri (the closest star outside our solar system) much less get to a place where we think there's an actual planet. Getting us to Proxima Centauri in less than a few hundred years would require technology that is several orders of magnitude beyond what we have now. If getting humans to another star system is a 100 on some "technology ability scale", then we're currently at about 2, which is not far ahead of poodles who are probably at 1.

    What about the idea that aliens might come to Earth to colonize the planet (and maybe vaporize us in the process)? You could argue that terraforming (or maybe aliens would call it xenoforming) could be a technology more advanced than FTL travel. With that assumption, you could imagine an alien race that can travel across the galaxy but not alter planets to suit their biological needs. Coming to colonize Earth could make sense. But this ignores the fact that several other requisite technologies would probably make their need to colonize obsolete.

    Before they had FTL travel, they likely spent many decades traveling at less that light speed and so chances are their ships are quite comfortable. In fact probably more like sailing biodomes than ships - someplace they could live indefinitely. Assuming their other scientists were hard at work while their engi

    1. Re:The Space Aliens Are Not Coming by Immerman · · Score: 2

      You've made a few large assumptions:
      > lacking FTL means it requires millenia to cross between stars
          - only to an outside observer: if you've got the energy to burn you can use relativistic time dilation to make the journey arbitrarily short.

      > FTL would necessarily be extremely advanced technology
        - in fact it could be something well with our own technological grasp, which we've overlooked because our concepts of the universe, and with it our physics theories are based on a fundamentally different set of assumptions. (After all, if FTL is possible, it probably means there's major flaws in our understanding of physics).
        - or they might be able to use one of the techniques we've already postulated, simply because they were lucky enough to find a large deposit of the sort of exotic matter that would make it possible within their solar system
        - or, they may have gained the technology from some other much more advanced space-faring species. After all, if anyone is jetting around the galaxy, sooner or later someone else will get their hands on the technology. And Earth *is* probably several billion years late to the galactic life game.

      >Studying alien life would get boring
      - Biologists have been studying life on Earth for centuries and are still finding interesting things. Completely alien life is liable to be no less interesting, no matter how many worlds your ancestors have explored. The span of potential life is nearly infinite - we need only look at out own geo-history to see how incredibly uncommon life resembling the modern forms is.

      That said, I've got to agree there's very little reason to assume conquest or colonization. Pretty much all the resources available here are more easily available... pretty much anywhere else. Meanwhile alien life is as likely as not to be severely incompatible to the point that terraforming a dead world is probably easier than a living alien one. And If you have to live in self-contained habitats to avoid being poisoned by the local ecology, conquest seems... ill-advised.

      On the other hand I can think of two things Earth offers that might not be common or easily made - a rocky world with a strong magnetosphere (important if you want a stable atmosphere), and a pre-oxidized planet capable of sustaining an oxygen atmosphere. After all, it took oceans teeming with algae billions of years to saturate the oceans with oxygen, and to then oxidize mineral formations on land enough that significant amounts of oxygen could start building up in the atmosphere. Tailored terraforming microbes could probably do the job in a small fraction of the time, but waiting thousands if not millions of years might be less appealing than simply transforming a living world conveniently free of intelligent life.

      If aliens did come here, especially without FTL, it seems the likely reasons are - biology, archaeology (in which case stealth might well be assumed, to avoid interfering with the primitive cultures they're studying), proselytizing (we've usually used it as a tool for conquest, but the missionaries themselves often have "nobler" goals), or broader cultural exchange. Or genocide. Can't rule out that the mere existence of other (intelligent?) life might be intolerable to some - either because of the threat we might eventually pose, or simply because they feel they must defend their position as the only intelligent life in the galaxy.

  27. I believe in UFO's and Crop Circles by randomErr · · Score: 2

    Here the deal. I live near a military base, two airports, a fault scar, and a great lake. We tons powerful winds and air traffic. So often we get UFO's making wide turns around densely inhabited areas. The local rumor is that the military is testing unmanned, long range, stealth flight vehicles. The crop circles are presumed to be caused by circular patterns similar to small localized tornadoes. In general there are one or two sightings a year the get documented and doesn't have an easy explanation. And no, I'm not one of those people that has filed one of those unexplained sightings. Still it keeps the dinner table conversations interesting.

    UFO's (in the sense of extra-terrestrials) are just the modern equivalent of ghosts. Enough "reliable" people have reported seeing UFOs and ghosts that the effect seems to be real as far as a human brain is concerned. However, the complete and utter lack of physical evidence suggests that they are purely a psychological effect and not a physical one.

  31. Didn't believe until I saw one myself by nwaack · · Score: 2

    I was taking my dog out to go to the bathroom around 2am. I was looking up at the night sky because it happened to be a particularly clear night and you could see a lot. What happened next baffles me to this day. Two green lights went silently from one side of the horizon to the other in about 10 seconds time. It seemed like they were attached to something; however, you could see clear space between the two lights. They were roughly as high as a jetliner, but definitely weren't a plane. I live near an airport and Lake Michigan (where the military routinely runs drills) so I'm very familiar with all that...it wasn't a plane, helicopter, drone, etc. Since then I've done my own research (satellite tracks and whatnot) and talked to amateur skygazers, but haven't gotten an answer. So yeah, I believe in UFO's because I saw one.
