Wow! mystery signal from space finally explained

Forty years ago a signal–called the Wow! signal–was obtained from space. Some speculated that it might be from an intelligent alien source. Read Wow! Communications from little green men?

Now it is argued that that it was not from little green men, but from a comet. Such is the hype around detection of a signal from aliens that common sense is ignored. Well, time, real science and cool heads have won out. The original source has been found.

The comets, P/2008 Y2(Gibbs) and 266/P Christensen, which were not known back 40 years ago when the Wow! Signal was first obtained, appeared again in the night sky from November 2016 through February of 2017.

An online news site reports from the astronomy team.1

The team reports that radio signals from 266/P Christensen matched those from the Wow! Signal 40 years ago. To verify their results, they tested readings from three other comets, as well, and found similar results. The researchers acknowledge that they cannot say with certainty that the Wow! signal was generated by 266/P Christensen, but they can say with relative assurance that it was generated by a comet.

The movie “Arrival”

arrivalposterRecently I watched the 2016 movie “Arrival“. It depicts the story of the arrival, at twelve separate locations around the earth, of twelve mysterious spacecraft. The key character, a linguistics professor, Louise Banks is seconded by the military to interpret the language of alien visitors.

The movie is based on the short story “Story of Your Life” by Ted Chiang (1998).1 It was directed by Canadian filmmaker Denis Villeneuve and stars Amy Adams, Jeremy Renner and Forest Whitaker.

Here is the trailer from Paramount Pictures:

The 7-foot tall aliens, heptapods,2 which look something like octopuses with 7 tentacles and a human hand, are depicted as enormously technologically advanced on humans. Their 7 tentacles each have 7 tendrils, out of the centre of which they eject an ink-like substance. Remember octopuses produce a black ink like substance. (And you might ask why all the 7’s. It’s science fiction after all.)

Alien language and perception of time

These alien heptapods use a vocal communication that is unpronounceable by humans (classified as Heptapod A), but, as professor Banks discovers, they also have a written script (Heptapod B), which can be dissected and interpreted. But strangely enough the vocal and writing components are unrelated, in the sense that Heptapod B does not represent sound. Heptapod B is written with the ink-like substance they eject from their tendrils and they are able to manipulate it in space to form the characters of Heptapod B.

We are told that a deep understanding of their language can induce a non-linear perception of time in those who learn it. This idea is where it really gets crazy.arrival_2016_heptapod_and_doctor

The story introduces the concept of when one learns a new language, one also learns to think the same way that the producers of that language think–the Sapir-Whorf hypothesis–because one’s brain is rewired to think that way.

Then, with this new perception of time, time-like loops are introduced (really time paradoxes) where, because the professor experiences (in her thoughts or perception) the future, she gets knowledge (of future events) that she then uses to determine the future events she perceives.

The concept here of our perception of time does have some basis in real physics. It is still an open question of why do we remember the past and not the future. That might sound strange to some but most of the laws of physics are time reversible. The Second Law of Thermodynamics, where entropy never decreases in a closed system, but generally increases, is an exception and the primary reason we always perceive the forward arrow of time.

However, for particle physics (including electromagnetism) there is no preference to which way time flows. Physicists call this a symmetry. And in this movie this is highlighted by the name, Hannah, of the yet to be conceived daughter of Prof. Banks, about whom she experiences future memories. The word “HannaH” is a palindrome–a sequence of letters or characters that can be read either forward or backward and produce the same word.

arrival-movie-symbolsHeptapod B is written in a circular way and is palindromic. At least that is what I understood it was intended to be. Looking at one of the alien sentences (on the right) it does not seem to have reversible symmetry, in the structures that form their words (spiky bits that stick out), though, of course, a circle is not linear in one sense as it is represented on a plane.

Of course, this story is just that, a story and total fiction. Nevertheless, it is an entertaining one.  Continue reading

Did aliens hack the Voyager 2 space probe in 2010?

I don’t know how I missed this news item back from 2010! Then NASA reported a single bit-flip error occurred in Voyager 2’s software code used to communicate with Earth. That sounds pretty mundane in today’s IT savvy world where we are all used to software errors and corrupt code.

Artist's concept of Voyager in flight.

Artist’s concept of Voyager 2 in flight.

But sometime the corruption of code is due to deliberate interference. Hackers hack into computers everyday for fun or more nefarious reasons. In this instance several scientists suggested that the on-board computer was hacked by an alien race (from another star system) who were trying to communicate with us.

But note the Voyager 2 space craft at that time was nearly about to cross over into what we would call interstellar space. It was about to leave the solar system in 2010 at a distance of 90 times the distance between the sun and the earth. That is about 8.6 billion miles or about 14 billion kms. That means it takes a light signal nearly 13 hours, travelling at nearly 300,000 km/s, to travel from the space probe to Earth. For NASA to send and receive a signal that would take twice that time, nearly 26 hours. It is certainly at a distance where one can easily discount any Earth based hacker.

The following is excerpted an online news item from 6 years ago and is typical of the several available.1

NASA space probe Voyager 2, which left earth 33 years ago, may have been hijacked by aliens who are now trying to make contact with earth according to a German academic.

The craft, which is 8.6 billion miles from earth on the very edge of the solar system, has been sending back data ever since it was launched – until last month when it briefly stopped transmitting before starting to send strange messages that scientists cannot decipher.

German academic Hartwig Hausdorf believes the change could be down to extraterrestrials. He says that because the rest of the spacecraft is still working normally there may be more to the cryptic messages than meets the eye.

“It seems almost as if someone has reprogrammed or hijacked the probe,” he told German newspaper Bild. “Thus perhaps we do not yet know the whole truth.”

NASA was much more circumspect stating that they believe it was due to this one corrupt bit of code. That may have occurred due to radiation in space or impact by a highly energetic particle which flipped the bit. Continue reading

Aliens are all around us?

With the rapid development of space technology, mankind has accelerated its search for extraterrestrial life, especially intelligent life. This has even spawned a new branch of science—astrobiology (lit. ‘star-life-study’)—despite not a shred of evidence for such life being found in some 50 years of searching. With advances in space-based telescopes, like Kepler, it is widely hoped this situation will soon change.

What is behind this belief in alien life evolving on other planets around other star systems?

It is the rejection of the Creator.

This means one must explain life on Earth as having arisen spontaneously (and therefore, the reasoning goes, it must also have done so elsewhere in the universe, many millions of times).

But as famous evolutionist (and astrobiologist) Paul Davies has reminded us in a recent Scientific American article,1 leading evolutionists had in past decades opposed this idea of ‘ETs everywhere’.

Why? Because they had faced up to the nigh-insuperable difficulty of trying to imagine a way to have the information systems of reproducing life evolve from raw chemistry.

Wow! Communications from little green men?

Several years ago (2010) I met an astronomer from Jodrell Banks radio telescope (one of the first big ones operated by the UK) and she told me the story of a signal being detected, which was thought to be from some intelligent alien source in the cosmos.

The signal was detected at 10.30 am every time. After some investigation, it turned out to be the microwave oven used to heat the muffins for morning tea. It was from an intelligent source after all, but not from space. Her anecdote sounds very similar to what was proven to have been the source of some anomalous signals at the Parkes radio telescope in Australia.

According to Simon Johnston, head of astrophysics at CSIRO, in 1998 the Parkes radio telescope began detecting some fast radio bursts and related signals named perytons once or twice a year. It was theorised that these may have been signals from another galaxy, or emissions from neutron stars becoming black holes, or just interference from lightning strikes. But in 2015 it was determined that perytons were detected by the Parkes telescope when staff opened the door of the microwave oven at the facility to heat their lunch.1

“ … 1 January [2015] they installed a new receiver which monitored interference, and detected strong signals at 2.4 GHz, the signature of a microwave oven.”1

Immediate testing of the facility microwave oven did not show up any perytons. Until, that is, they opened the oven door before it had finished heating. “If you set it to heat and pull it open to have a look, it generates interference,” Johnston said.

Problem solved! No signal there from ‘little green men’ either! Continue reading

Life in the Universe is the ultimate miracle

Life in the universe is rare, so rare in fact, I would wager that sentient life is only found on planet Earth. For nearly 50 years the collection of telescopes and scientists under the umbrella name of the Search for Extraterrestrial Intelligence (SETI) have searched among the wavelengths of a myriad stars in search of a radio signal, any signal, from intelligent life. But have they detected any? Apart from detecting the odd microwave oven in their own establishment,1 no is the answer.

In 2013 Space.com headlines with “Alien Life May Be Rare Across the Universe2 but on July 23, 2015 NASA announced the discovery of Earth 2.0 with a headline on Space.com of “NASA Finds Closest Earth Twin Yet in Haul of 500 Alien Planets.”3

It is all over the news with a host of pictures of Earth 2.0. But wait, they are only artists’ conceptions.” One such drawing is reproduced here.

The report is that NASA found a near twin to Earth named Kepler-452b. It orbits its sun every 385 days, is 60 per cent larger in diameter than Earth, has a mass probably 5 times that of Earth and is located about 1,400 light years away. It’s a big deal! But why? Continue reading

Is Lucifer helping the Vatican astronomers look for extraterrestrials?

LUCIFER is an acronym for the instruments lengthy title, “Large Binocular Telescope Near-infrared Utility with Camera and Integral Field Unit for Extragalactic Research.”  Why would someone choose such a name? Even the acronym was crafted from only some of the letters of the words in the title above. They had to work at getting that name, like they really wanted to say something, or at least get our attention. Well, they have it now. The instrument called LUCIFER is attached to the University of Arizona’s Large Binocular Telescope (LBT) located on Mt. Graham in south-eastern Arizona. And the Vatican-owned Vatican Advanced Technology Telescope (VATT) is adjacent to it.

According to Tom Horn and Chris Putnam, the Vatican is awaiting an alien saviour. This is what they write in their book “Exo-Vaticana”, so says Ecumenical News.2

Horn said Brother Guy Consolmagno, who has also been called the papal astronomer, told the authors some astounding information. (emphasis added)

“He (the papal astronomer) says without apology that very soon the nations of the world are going to look to the aliens for their salvation”, said Horn.
