The researchers also found that the ‘Wow!’ there was a brief increase in the brightness of one of several H1 (neutral hydrogen) clouds in the telescope's 'field of view'. The 1977 signal was similar to what Arecibo saw, in many ways. The only difference between the signals seen in Arecibo and the ‘Wow!’ – this is their brightness.

The researchers were able to identify the clouds responsible for the signal, but not the source. The results show that the source is much further away than the clouds that produce the hydrogen signal. This understanding can allow us to pinpoint the exact location of the signal's origin and ensure continuous monitoring of subsequent events.

The ‘Wow!’ initially, it was interpreted by many as a technosignature. By explaining where the signal came from, this study describes a new source. The researchers suggest that the signal may be the first recorded event of an astronomical maser flare in the hydrogen line.

The study also shows that signals like this can be detected using radio telescopes like Arecibo. Scientists found several signals similar to this one during observations from Arecibo between 2017 and 2020. These signals were less intense than ‘Wow!’ but had similar characteristics.”

Astronomers have found out the probable origin of the mysterious ‘wow’ signal from space (link in Russian)

https://hi-tech.mail.ru/news/113873-proishozhdenie-zagadochnogo-vau-signala-iz-kosmosa/

“The search for the source of radiation, which was sometimes attributed to extraterrestrials, took almost 50 years.

The history of the ‘wow’ signal stretches back to 1977, when it was discovered accidentally by the Big Ear radio telescope. Since then, such radio bursts have not been recorded, despite the improvement of technology. This has long led particularly romantic researchers to believe that the signal came from an alien civilization. However, a new study published in IFLScience shows that the mysterious signal most likely has a completely natural origin. <…>

Astronomers had tried many times to find the same signal, including by scanning the same patch of sky. But to no avail. Until scientists from the University of Puerto Rico began studying archived data from the Arecibo radio telescope. They discovered something intriguing in the dataset collected between 2017 and 2020. During that time, the observatory was monitoring nearby red dwarfs, searching for potentially habitable planets. But in several cases, a distinctive signal was detected.

The authors identified it as radiation from interstellar clouds of cold hydrogen. Light from red dwarfs hit these clouds, and the radio telescope recorded this moment. Scientists compared the frequency and characteristics of the bursts with the ‘wow’ signal and realized that they were dealing with the same radiation, although much less intense.

This allowed the researchers to conclude that in 1977, Big Ear accidentally recorded the same process. Only in this case, the cold cloud of hydrogen was illuminated not by a red dwarf, but by some short-term powerful pulse, for example, a flash from a magnetar – a neutron star with an extremely powerful magnetic field. This could explain the high intensity of the signal, as well as the fact that such bursts were no longer recorded – for this to happen, a combination of not very likely circumstances should occur: from the right moment of observation to the hydrogen cloud falling under the flare.”

Iconic Wow! signal may finally have an explanation (it's still not aliens) (August 20, 2024)

https://www.iflscience.com/iconic-wow-signal-may-finally-have-an-explanation-its-still-not-aliens-75619

It is curious that in 1977, a ‘signal from space’ was recorded, then it was not repeated, and after the final destruction of the Arecibo telescope in 2020, researchers took archival data from it for the period from 2017 to 2020 and finally found out that there was nothing extraordinary.

Arecibo (Radio Observatory, National Astronomy and Ionosphere Center, NAIC, first link in Russian)

https://ru.wikipedia.org/wiki/Аресибо_(обсерватория)

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

“The Arecibo main radio telescope was one of the largest single-aperture telescopes in the world. It was put into operation on November 1, 1963; on December 1, 2020, it collapsed as a result of wear and tear of the supporting structure.       <…>

The observatory has a 0.5 MW transmitter for conducting research under the radar astronomy program. With the help of this transmitter, the ‘Arecibo Message’ was sent on November 16, 1974. <…>

The destruction [of the telescope occurred in 2 stages, between which 3 years passed:]

[Prelude] In January 2014, a 6.5-magnitude earthquake caused damage to one of the cables, but it was repaired.

[Stage 1] On September 20, 2017, hurricane Maria snapped the 29-meter radar antenna of the radio telescope in half; its debris penetrated the main mirror of the telescope and damaged the auxiliary one.

[Stage 2] On August 10, 2020, during the Atlantic typhoon [hurricane] Isaiah, one of the steel cables attached to the three masts holding the radio wave receiver at an altitude of 137 meters burst; accordingly, the load on the remaining cables increased. The telescope's mirror was severely damaged by a burst cable that tore a hole about 30 meters long.

On November 7, one of the main steel supporting cables of the radio telescope broke, which destroyed part of the mirror itself. On November 19, NSF announced the decision to close the radio telescope.

On December 1, NSF reported the collapse of an 820-ton structure with receiving equipment on the main mirror of the radio telescope, which led to the destruction of the latter. <…>

Scientific contribution of the observatory [selected]

On November 16, 1974, a message to other civilizations was sent in the direction of the globular star cluster M13, located 25,000 light-years away in the constellation of Hercules.

According to experts, the failure of the Arecibo radio telescope actually put an end to the search for extraterrestrial civilizations.”

Farewell to Arecibo (link in Russian)

https://habr.com/ru/articles/529180/

“The Arecibo radio telescope, unlike many of its smaller counterparts, was not just an ‘ear’, it could also ‘speak’, i.e. work as a radar. This opened up unique opportunities for scientists-experimental astronomy. For the most part, astronomy is a passive science: scientists create scientific instruments and observe, collect signals and light that come to Earth naturally. Arecibo also shone in the radio range itself, and could receive reflected rays. So he managed to map Venus with a resolution of up to 1 km. More precisely, only the Soviet Venera and the American Magellan were able to create maps.”

Maria (hurricane)

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

“Entering the Caribbean Sea, Maria weakened slightly to a Category 4 hurricane due to land interaction with the island of Dominica, however it quickly restrengthened to a Category 5 hurricane and attained its peak intensity with winds of 175 mph (280 km/h) and a pressure of 908 mbar (hPa; 26.81 inHg) at 3:00 UTC on September 20 while southeast of Puerto Rico; this ranks it as the twelfth-most intense Atlantic hurricane since reliable records began. An eyewall replacement cycle caused Maria weaken to Category 4 strength before it made landfall near Yabucoa, Puerto Rico at 10:15 UTC (6:15 am local time) that day with winds of 155 mph (250 km/h) – the most intense to strike on the island since the 1928 San Felipe Segundo hurricane.”

At first I was interested in the possibly false information about 1973, then the next link linked to 2017, Arecibo, and a ‘similar signal’. Naturally, I went to the Wiki article about Arecibo, where I found out that the first serious destruction of this telescope occurred on September 20, 2017, which is 10 days after the end of my Fantastic Week.

Arecibo sent the first signal to space – ‘extraterrestrial civilizations’ – in 1974, interestingly, this is one of the main plot points of Liu Cixin's book “3 Body Problem”. And I'll remark (I noticed this on November 13, 2025, at 12:44 am) that on September 20, 2017, it was the Arecibo telescope's radar antenna that collapsed. That is, it was the part of the telescope that sent a signal into space in 1974.

Calculator 274

“The history they try to teach Timers changes with every Reality Change. Not that they realize that. In each Reality, their history is the only history. That's what's so different about Primitive history. That's the beauty of it. No matter what any of us does, it exists precisely as it has always existed. Columbus and Washington, Mussolini and Hereford, they all exist.”

The calculator calculates the number of days that have passed between two dates (link in Russian)

https://planetcalc.ru/274/

I found out that the calculator I selected for Google search: ‘day calculator’ (it was the second number in the list) has the name Planetary Calculator. When I once again calculated the number of days between July 27, 1972 and April 27, 1973 (the second date is my birth, the first is the possible date of conception), and got the result – 274 days, I noticed that this calculator has the number 274 in the link, i.e. we can say that it is 274th calculator among 1106 calculators on this specialized site.

Numerology uses a combination of a person's day, month, and year of birth to understand something. If we combine the day and month (without the year) of my birth date in sequence, we get 2704 or 274.

Human pregnancy (link in Russian)

https://ru.wikipedia.org/wiki/Беременность_человека

“From the moment of conception, on average, pregnancy lasts approximately 9 months (266–270 days), with extreme values of 250–285 days.”

Why do I think my conception date could have been 27.07?

On Sunday, July 16, 2023, my mother told me that my birth took place with great difficulty, ‘in pain’. In the morning of April 27, 1973, the doctor decided to terminate the pregnancy by artificial [medical] methods. My guess is that special chemicals were used to stimulate the birth process and tools were used to reach the baby. As a result, I had a massive hematoma on the top of my head and the doctors told my mother that I would have serious psychological problems in my life, and for this reason the child ‘should be kept in a greenhouse’.

The doctor reasoned his decision to terminate the pregnancy artificially by saying that my mother was already due to give birth, and I was expected to be a large child, and if we continue to wait for the natural development of events, problems could arise for her.

That is, I was supposed to be born naturally in a few days, maybe May 1–2, 1973. I assume that according to the doctor, by April 27 the gestation period had already exceeded the average of 270 days by 4 days. That is, these 4 days could be decisive in his argument.

She also told me a curious story that after I was born, the next morning, the wrong baby was brought to her, the children were mixed up, but she noticed the substitution. I guess it was easy to do, because I had a head injury.

In any case, I do not know the exact date of conception and can only assume that it could have been, as well as July 27, 1972, and in the days adjacent to this date.

I will note that the date 27.07 appeared in my history not at all because I assumed the day of my conception on this particular date, but because when I found out about the failures in Berezniki, after reading on the Internet that the date of the first failure at the mine fell on the 27th (the night from July 26 to July 27, 1986), I decided to count the number of days from that date to my birthday. It was precisely because of the exact numerical coincidence of the day in the dates (both had the 27th) that I became interested in this event. If the day of the failure in Berezniki hadn't been the 27th of the month, I likely would have passed it by and would not have noted for myself the events related to the geological catastrophe near Berezniki.

On June 25, 2023, I found the following interesting date in history:

The Jerusalem Temple (link in Russian)

https://toldot.com/Hram.html

“The Temple of Solomon was destroyed by the Babylonians 410 years later, and the Jews were taken captive. After 70 years, the exiles returned, rebuilt Jerusalem, and rebuilt the Temple on the Temple Mount, which became known as the Second Temple. It stood for 420 years and was destroyed by the Romans in 70 AD (according to another version, in 68 AD).

On 9 Av 3338 from the creation of the world (AM), the Babylonians destroyed and burned the First Temple in Jerusalem – 410 years after its construction. The inhabitants of the country were driven to Babylonia. The Babylonian exile lasted for seventy years – until the Jews returned to their country and rebuilt the Temple with great effort. But on 9 Av 3828 (AM), four hundred and twenty years after its construction, the Second Temple was destroyed and burned by the Romans.

All the greatness and significance of the Temple was that it was the place of the Creator's presence in this World. The Creator is present everywhere, but there it was felt most strongly. Therefore, constant miracles took place in the Temple, the laws of nature, as if they had no power there. But that's not all. In the Temple there was not only the presence of the Creator, but also the spiritual essence of the entire Jewish people, the very one through which the Glory of the Creator, as it were, descended into this world. Their unity was the spiritual, invisible Temple. This is the foundation. And subsequently, a material, tangible Temple was built around the Temple of the Spirit. Since then, the life of a Jew at that time revolved around the Temple. He was the heart of the people. This is about the Temple in one word.

Based on this and in connection with our topic, a question should arise. If the Temple was a place of the presence of God himself, then such a Temple must have existed forever. Is there any force in the world that can destroy it?!

Answer. Indeed, no power in the world could destroy the Jewish Temple except the Jews themselves. Except for those for whom it was built. After all, as mentioned, the unity of the Creator and the people of Israel was the essence of the spiritual Temple. Therefore, only the dissolution of this Unity could destroy the Temple.

And how could this happen? Like the dissolution of a marriage between a husband and wife. In all the holy books, the relationship between the Creator and the people of Israel is likened to that between a husband and wife.

But when the Jews became mired in sins that cannot be committed unintentionally, only on purpose, in spite of and out of touch with the Creator, then the spiritual impurity generated by these sins became incompatible with His holiness. And this led to the dissolution of the union. The presence of the Creator has left this world. When the Jewish people no longer appreciated the miracle of the Creator's presence in their midst, they banished the Creator's presence by their behavior. It was then that the destruction of the Spiritual Temple itself led to the destruction of the material Temple.”

The First Temple (Solomon's Temple) (second link in Russian)

https://en.wikipedia.org/wiki/Solomon%27s_Temple

https://ru.wikipedia.org/wiki/Первый_Храм

“The First Temple, also the Temple of Solomon (950–586 BC) – was a Jewish temple in Jerusalem, the name of the Jerusalem temple before its destruction by the forces of Nebuchadnezzar II in 586 BC. Its construction is described in The Hebrew Bible, within the book 3 Kings, chapters 8–9 and 2 Chronicles, chapter 3.

Transfer of the Ark of the Covenant

According to biblical narrative, the purpose of Solomon’s Temple was to store the Ark of the Covenant. 1 Kings 8:1–9 and 2 Chronicles 5:2–10 record that in the seventh month of the year, at the feast of Tabernacles, the priests and the Levites brought the Ark of the Covenant from the City of David. Within the temple, the Ark was placed inside the Holy of Holies.

Destruction by the Babylonians

Date of extinction: August 586 BC and 422 BC.

According to the Bible, the Temple was plundered by King Nebuchadnezzar II of the Neo-Babylonian Empire when the Babylonians attacked Jerusalem during the brief reign of Jehoiachin c. 598 BC (2 Kings 24:13).

A decade later, Nebuchadnezzar again besieged Jerusalem and after 30 months finally breached the city walls in 587/6 BCE. The city finally fell to his army in July 586/5 BCE. A month later, Nebuzaradan, commander of Nebuchadnezzar's guard, was sent to burn and demolish the city. According to the Bible, ‘he set fire to the Temple of Yahweh, the royal palace and all the houses of Jerusalem’ (2 Kings 25:9). Everything worth plundering was then removed and taken to Babylon (2 Kings 25:13–17).

Jewish tradition holds that the Temple was destroyed on Tisha B'Av, the 9th day of Av (Hebrew calendar), the same date of the destruction of the Second Temple. Rabbinic sources state that the First Temple stood for 410 years and, based on the 2nd-century work Seder Olam Rabbah, place construction in 832 BC and destruction in 422 BC (3338 AM), 165 years later than secular estimates. The Jewish historian Josephus says: ‘the temple was burnt four hundred and seventy years, six months, and ten days after it was built.’

Most of the inhabitants of Jerusalem were killed, and the rest were taken captive and taken as slaves to Babylonia (the Babylonian captivity). The Ark of the Covenant was lost.

In memory of the destruction of the temple and the events that accompanied it, four fasts were established, among which the fast of 9 Av marked the day when the temple was burned.”

Nebuchadnezzar II (second link in Russian)

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

https://ru.wikipedia.org/wiki/Навуходоносор_II

“In 589 BC, Zedekiah refused to pay tribute to Nebuchadnezzar, and he was closely followed in this by Ithobaal III, the king of Tyre. In 587 BC, Ammon, Edom and Moab likewise rebelled. In response to Zedekiah's uprising, Nebuchadnezzar conquered and destroyed the Kingdom of Judah in 586 BC, one of the great achievements of his reign. The campaign, which probably ended in the summer of 586 BC, resulted in the plunder and destruction of the city of Jerusalem [on July 18, 586 BC, Jerusalem, suffering from famine and pestilence, fell – in the second link], a permanent end to Judah, and it led to the Babylonian captivity, as the Jews were captured and deported to Babylonia. Archaeological excavations confirm that Jerusalem and the surrounding area was destroyed and depopulated.”

Some sources give the date of the destruction of the First Temple as 422 BC, but most sources give the date of 586 BC (or 587 BC).

“In July 586 BC, the Babylonian king Nebuchadnezzar II captured and destroyed Jerusalem, and the First Temple was completely destroyed. Almost all the inhabitants of the city, including the last king of Judah, Zedekiah, were taken captive and resettled in Mesopotamia.

However, the Babylonian captivity of the inhabitants of Judea lasted less than 50 years. In 539 BC, the Persian king Cyrus II the Great (559–530 BC) conquered Babylon and incorporated it into the Achaemenid empire. The peoples who were forcibly settled in Mesopotamia, Cyrus allowed to return to their countries. The Book of Ezra tells us that in the first year of his reign, King Cyrus issued a decree, according to which the Jews were allowed to rebuild the Temple.”

Second Temple (link in Russian)

https://ru.wikipedia.org/wiki/Второй_храм

“It is generally accepted to date the completion of the Second Temple to 516 BC, but there is an assumption that the end dates back to 417 BC. In Jewish tradition, the construction dates back to 348 BC.

The period between the destruction of the First Temple (the Temple of Solomon) and the construction of the Second Temple is 70 years (586–516 BC).

The construction was finally completed only under Agrippa II, during the reign of Roman procurator Albinus (62–64 AD). That is, just 6 years before the destruction of the temple by the Romans in 70.”

“4. The fast of the ‘Fifth Month’ is the saddest day of our year, the anniversary of the destruction of both temples – the Ninth of Av. However, this number itself is not mentioned in the Books of the prophets (but the seventh and tenth numbers are mentioned). According to the Talmud, the Temple was set on fire on the evening of the Ninth Av, and it burned all day on the Tenth, and so Yirmiyahu mentions the Tenth (Talmud, Taanit 29a). (This may also have happened during the destruction The Second Temple, as Josephus, who lived through these events, also cites the Tenth Av. Interestingly, in the Talmud, R. Yochanan said that he would prefer to make the Tenth Av a day of fasting, but the rest of the sages do not agree with him, because the main day of misfortune is the beginning of punishment.)

5. There is a dispute among early commentators (Rishonim) about the year in which it was destroyed The Second Temple. The fact is that according to the Talmud, the Temple was destroyed in the year after Shmita (the seventh year). The question is whether this refers to the year of destruction itself, or the year after it. According to some opinions, the Temple was destroyed in 3828, and according to others 3829. It would seem that these years correspond to 68 and 69 years of our era. But most modern sources mention that The second Temple was destroyed in 70 AD. The reason for this is another dispute. The fact is that during the course of history, when the Jews counted the years from the ‘Creation of the world’, sometimes the ‘first year’ consisting of the first ‘five first days of creation’ was taken into account, and sometimes it was not taken into account. According to the Rambam, the Temple was destroyed in the year 3829 AD, which was ‘created’ on Rosh Hashanah, the First Tishre, i.e. not counting the five days of the ‘First Year of Creation’. Since, according to the Rambam, our current calendar also takes into account the year before Adam, the Temple was destroyed in 3830 according to our calendar, i.e. in 70 AD (see Rambam, Mishneh Torah, ‘laws of Shmita’ 10:2, Choshen Mishpat 67:8).”

For the first time, the Gregorian calendar was introduced on October 15, 1582 by Pope Gregory XIII in Catholic countries to replace the former Julian calendar: the next day after Thursday, October 4, was Friday, October 15.
