In late 1991, astronomers may have detected an extraterrestrial space probe in near Earth space. Who makes such a startling statement? Some wild-eyed UFO believer? A renegade scientist? A tabloid psychic? No, not at all. His name is Duncan Steel.
Who is Steel, you wonder? I'll quote from the jacket of his new book, Rogue Asteroids and Doomsday Comets (Wiley, 1995): "Duncan Steel, Ph.D. is a research astronomer at the Anglo-Australian Observatory and a research fellow at the University of Ad elaide, Australia. A world renowned authority on the comet, hazard, he has served on both the Detection Committee and the Intercept Committee created by NASA to assess the threat of comet and asteroid collisions and investigate technologies to avert such impacts." Not only that, but Steel is thought of as a "longtime skeptic" and "as someone who almost invariably has his facts right," according a reviewer in an Australian magazine (Colin Keay in The Skeptic, Vol 15, No.3, 1995).
So how did Steel come to his startling conclusion? Here's the scoop. On Nov. 6, 1991 Jim Scotti using the Spacewatch telescope at Kitt Peak in Arizona discovered a body which he initially described as a "fast moving asteroidal object," a month befo re its closest approach to the Earth. Later, the object's heliocentric orbital elements suggested instead that "the object might be a returning spacecraft." As the approximately 30-foot object, now labeled 1991 VG, neared the Earth, astronomers at the Eur opean Southern Observatory tracked it and found strong, rapid brightness variations suggestive of reflections from a rotating spacecraft.
His curiosity piqued, Steel decided to investigate the different probabilities for the nature of this object, according to his account "SETA and 1991 VG," published in The Observatory (Vol. 115, pp. 78-83, 1995). "SETA," by the way, stands for "Search for Extra-Terrestrial Artifacts" within our Solar System. Steel first wondered whether the object could be a returning spacecraft, given those brightness variations and its very Earth-like orbit. But he found that none of the handful of man-ma de rocket bodies left in heliocentric orbits during the space age have purely gravitational orbits returning to the Earth at that time. Besides, if 1991 VG was a man-made rocket body, then its return to our vicinity and its accidental detection by Spacew atch was, Steel calculated, a very unlikely event, on the order of one in 100,000 per year.
So could it be a natural body, Steel then asked himself? One factor that strongly argued against this interpretation was the light variation the object exhibited, which resembled those of rotating artificial satellite trails seen in wide field astronomic al photographs. The second factor is that the object's pre-encounter orbit of 1991 would have made it unstable in close approaches to the Earth on a time scale measured in millennia. This means, that if it is an asteroid, it would have recently arrived in that orbit, which is, Steel states, very unlikely.
Therefore, concludes Steel, we have to seriously consider the possibility that this object has "an alien genesis." Given our meager surveillance of near-Earth objects, there is little chance that objects of this kind would have been spotted in the past. There is nothing here, in other words, that would contradict the alien probe hypothesis, says Steel.
Steel's probability analysis does not end here. He goes on to tackle an issue that not doubt made his colleagues pale. Was 1991 VG under control or making a random passage by the Earth, he asks? Since only "about one in 50 objects passing randomly within 0.022 AU have perigee heights as low as 0.0031 AU," Steel thinks there is a "possibility that it was a singular alien space probe on a controlled reconnaissance mission."
Steel ends his surprising analysis on a cautious note, however. His personal bias, he states, is that 1991 VG is really a man-made artificial object. But if it was, he concludes, then it's observation was really an incredible fluke. So much so, in fact, that scientists, he says, should "consider the possibility of some other origin for it."
All in all, it's quite an amazing piece of work. But I can't help but wonder if he's being serious. After all, it does appears in an April issue. Nobody likes to be a fool.
On the other hand, Steel is not the kind of scientist who pulls his punches. In his new book about the threat that asteroids and comets pose to life on Earth, he speculates that Stonehenge was originally erected during a period of intense celestial bombar dment--some perhaps of Tunguska-like force--about 5,000 years ago. Stonehenge's purpose, he ventures, was "to monitor meteor rates in order to predict when storms were due." Steel doesn't expect this hypothesis to be warmly welcomed by anthropologists and antiquarians. Nor will SETI astronomers take kindly to the notion that an alien probe may have performed a reconnaissance mission of Earth in 1991. Of course, human-built space probes have done just that in our solar system for the past quarter century. Why couldn't someone out there be taking a peek at us?
Pretty cool. I think there may be probes from some place out there, billions of years is a long time.

Also I am not saying we need to turn unproven theories into facts, I find this whole argue meaningless. I am clearly talking about more-open mind by the main stream science, that's it!

I can think of no 'a priori' reasons why this might not already be true, but the debate hereabouts is, do the things people report have anything to do with this hypothesis? Worth debating, for sure!

I am not even talking about the 'invisible alien probe' because there is no clue about such things, though they may exist - even though one has the right to doubt when nothing suggests they do.

...So you don’t outright reject the notion that there’s a fire-breathing dragon in my garage. You merely put it on hold. Present evidence is strongly against it, but if a new body of data emerge you’re prepared to examine it and see if it convinces you.
(color emphasis mine)
the only sensible approach is tentatively to reject the dragon hypothesis, to be open to future physical data...

Gerald Livingston is an orbital garbage collector. For a hundred years, people have been abandoning things in space, and someone has to clean it up. But there’s something spinning a little bit higher than he expects, something that isn’t on the decades’ old orbital maps. An hour after he grabs it and brings it in, rumors fill Earth’s infomesh about an “alien artifact.”

That's what differs proper science from your so called 'scientists' that are nothing but people with some diplom and zero objectivity.

If something cannot be tested it doesn't exist? Lots of things one may not even imagine can exist and they may exist - if science doesn't accept this (correction: main stream science) - then this is pseudoscience! Or better change its approach.
Clearly you have reading comprehension issues. Science has gone about proving things that, when theorized, couldn't be proven.
