I don't question your sanity, and I think we in SETI@Home are probably one of the more accepting groups when it comes to UFO reports or discussions because we do, as you rightly point out, obviously believe in the likelihood or at least the possibility of other technical civilizations. But I think most of us have some grounding in science, and science is by nature skeptical. I would say it's entirely possible that some UFOs are indeed alien spacecraft. But there's no way to test that idea or investigate further, because the don't talk to us or stick around to be examined. As ever, extraordinary claims require extraordinary evidence, and we don't have any.

I agree with you that silent operation proves nothing either way. If some of these are spacecraft, they are operating with drives we don't begin to understand. As far as I know, radar doesn't have much luck picking these things up. So silent operation, at least a subsonic speeds, doesn't seem much of a stretch.

Sonic booms don't always happen (at ground level) when an aircraft flies overhead at supersonic speeds. Where the shock wave goes, its exact shape and intensity depend on a lot of factors including atmospheric temperature profile, wind profile, attitude of the aircraft, ground profile, instantaneous flight profile, shape of aircraft etc. Indeed the number of times I've not heard the boom from a supersonic overflight is probably greater than the number of times I've actually heard one.

I hear a sonic boom each time a whip is cracked. I heard a sonic boom when a meteorite passed directly overhead in Key West Florida. I heard a sonic boom each and every time a plane from Boca-chica Air Base flew faster than 700 MPH or so. The following photo shows a condensed vapor trail that forms when the temperature drops due to a quick drop in pressure. There's your UFO Disk which shows how atmospheric phenomena can produce a disk-like "object" and the accompanying mass hysteria. If you don't hear a boom when a hypersonic plane passes overhead it means that the object has outrun the boom which has dissipated some many miles behind it. You would always hear it if you were close to the location where the barrier was broken.

The unexplained UFO sightings are more like 5%, unless you believe that the Air Force is lying to advance the great government conspiracy. I am sure that Trump would tell us all in a tweet when our intelligence agency presents the fact that UFO's are stored at Roswell along with a few alien bodies.

I think your post makes a lot of sense.

If there are ET craft operating within earths atmosphere, they will have got here either on their own or via a mother ship and likely utilising FTL technology. Their drives will be nothing we understand, and they would likely use stealth technology anyway. All major governments have files on UFO occurrences reported and confirmed by reliable witnesses that simply defy explanation.

They could be genuine ET UFO's they may not be, we just don't know at our current level of technology. All Governments and security agencies simply have to keep an open mind, what else can they do. And nobody yet has asnswered to question why a highly advanced FTL technology species would bother with thousands of abductions. If we went to another star system would we?


Very interesting! You bring up many good points, and I missed the one that is, or should have been, to me, most obvious, the possibility of a "mother ship." Geez, that makes so much SENSE! These people, oops, aliens, MUST come from another star, and to do it they have to either exceed the speed of light, OR "bypass it" somehow. Maybe THAT's the secret, huh? If FTL speed is truly impossible, then there may be another way to get from there to here? Makes sense. Another thing about the idea of a mother ship is its size. Many of them could relax, in comfort, on their journey and not be cramped up in a small disk shaped "tin can." :) Also, their small saucer craft, powered by who knows what, at least doesn't have to lug around a giant fuel tank to fly. They just flip on the "anti-gravity" drive, or whats-it and go all around the Earth.

We know enough about our solar system to know, I think, for sure, that a species capable of FTL or its alternative, doesn't live around here. They surely do not come from Mars, Jupiter, Pluto, etc. Their mother ship uses a drive that doesn't need to stop at a "gas station." There are none in space. :) Our ships need fuel tanks to spew out hot gas from their exhaust, theirs do not.

As to WHY they bother to come here, and especially so often is a puzzle. The only thing I can think of is our atomic testing which started in 1945, about the time the majority of UFO sightings started. I wonder if they "picked up" on the "atomic signature" of our tests and those of the Russians? For all we know, and we know so little, an atomic blast could well send a "shock wave" far out into the universe? I seem to recall hearing somewhere that, at the center of an atomic blast, the heat reaches that of the interior of our sun? Is that true? What KIND of an electromagnetic wave could THAT generate? Maybe one strong enough to be heard a long long way? We do not know. They, our visitors, may have "heard" it and came to investigate? They may may come in self defense to put a stop to us if they felt we were so far along as to present a clear and imminent threat to life in our galaxy and beyond. It's speculation, of course, but a possible reason for their coming here at the dawn of our atomic age. Notice that in recent years atomic tests on Earth have gone way down in number, I think, and we are not seeing near as many UFO's as we did between 1945 and 1965. Interesting, huh?

I believe that most "SETI people" are on the forefront of thought in regard the existence of extraterrestrial life, else WHY are they here? Many here seem to be either engineers, like me, scientists, or others with a high level of technical knowledge. I think only a very few earn a living selling hot dogs from a cart on a street corner? That being said, why are so many seemingly afraid to think UFO's are real, and just a big joke? Instead of laughing and poking fun at the idea; they should study the subject thoroughly and with open minds, and try to fit the pieces together. The universe is TWICE the age of planet Earth, by billions of years, and the odds are there is a LOT of intelligent life far out in the older part of the universe, if not in our small corner. One should NOT hear the sound of "one hand clapping" when someone raises the subject. :)

OK, I will shut up. :) All comments and ideas are welcome. Sorry, I tend to "rattle" on at times.

Project Orion, circa 1958 to 1964...
https://en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion)


The idea of rocket propulsion by combustion of explosive substance was first proposed by Russian explosives expert Nikolai Kibalchich in 1881.

This came about because of Newton's 3rd Law of motion, to wit: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." OR, to cut to the chase, "For every reaction there is an equal and opposite reaction."

A proposal, later, in the 1950's, was to propel spacecraft, using atomics, far more efficiently than by the use of chemical propellants spewing out of an exhaust pipe.

The theory behind it, which looked good on paper, was that the propulsion would occur as a reaction to tiny atomic bombs ejected out behind the craft; as each bomb exploded, the craft would be accelerated forward. Geez, huh? The name given to this was "nuclear pulse propulsion."

Two things stopped the project: one, the biggie, was the nuclear radiation each tiny blast would leave in the atmosphere, and the second was the onset of test ban treaties in the early 1960's. A workaround was proposed for the contamination of the atmosphere, and that was to use this propulsion method only in deep space.

I watch a show, called "NASA's Unexplained Mysteries," on cable. It details many sightings by our astronauts of possible UFO related events, while in earth orbit, and also 2 UFO sightings on Mars, early on, when our rover was lowered below a hovering lander to the surface to avoid damage. The UFO's purportedly saw us landing, watched us, and took off.

The story of the Orion project is narrated by Freeman J.Dyson in his book "Disturbing the universe", which speaks also of space travel and colonies into space. I enjoyed reading it.

A lot of these new propulsion ideas sound great until they get to the end of the description where they mention in passing that it would need to harness the energy of a star to make it go anywhere. No time soon I presume.

I agree, Bob. Knowing that some sort of "warp drive" is theoretically possible doesn't help very much if you need the power of a galaxy to make it work. But two drive schemes are, in fact, quite possible. Neither is FTL, but still great leaps forward. One is an ion drive, and the other is the aforementioned "nuclear pulse" drive, i.e. the Project Orion idea. The beauty of the last is that the more massive the ship is, the better the ride will be. Abandoning this concept was, IMHO, utterly stupid. The spacecraft could be assembled in low earth orbit, with international buy-in, and incorporate some other form of propulsion, as well. Remember that radiation is space isn't really a problem, as long as the ship is adequately shielded. There's an interesting fictional treatment of this idea in the Niven-Pournelle novel "Footfall".

"Second Life" Anyone?

https://en.wikipedia.org/wiki/Second_Life

Hi All,

Wouldn't it be fun if we all could get together in our spare time and chit chat "in person?" If you haven't heard of it, 'Second Life' id the largest 3D Virtual World on planet Earth. I think it has about 13 million members worldwide? It is FREE and you can create your own personal avatar and show off your handsome self. :) All you need is a fairly good net connection and a decent graphics card.

Do a 'Google' on the name and join the fun? My name in SL (Second Life) is Linda Latte. IM me when you get there and we can meet!
