That’s very funny. Caught me in the middle of dinner, spewing kale.
Now if my fathers’ collection had survived all of the military moves we could certainly check.
Wouldn’t that meteor swarm be heading towards us?
I thought it was Uranus... hehehe.... hehehe
I meant that it should be possible to determine what the object was by analyzing the embedded grains, if they actually exist.
The massive black hole in the center?
Just kidding.
Lol!
You’re too smart and well read for me. If this happened in the early 1900s why didn’t the Russians analyze the embedded grain evidence?
Assuming it even exists, maybe they simply never thought about it. Might be on the microscopic scale.

The Tunguska impact event is one of the great mysteries of modern history.
The basic facts are well known.
On 30 June 1908, a vast and powerful explosion engulfed an isolated region of Siberia near the Podkamennaya Tunguska River.
The blast was 1000 times more powerful than the bomb dropped on Hiroshima, registered 5 on the Richter scale and is thought to have knocked down some 80 million trees over an area of 2000 square kilometres.
The region is so isolated, however, that historians recorded only one death and just handful of eyewitness reports from nearby.
But the most mysterious aspect of this explosion is that it left no crater and scientists have long argued over what could have caused it.
The generally accepted theory is that the explosion was the result of a meteorite or comet exploding in the Earth’s atmosphere.
That could have caused an explosion of this magnitude without leaving a crater.
Such an event would almost certainly have showered the region in fragments of the parent body but no convincing evidence has ever emerged.
In the 1930s, an expedition to the region led by the Russian mineralogist Leonid Kulik returned with a sample of melted glassy rock containing bubbles. Kulik considered this evidence of an impact event. But the sample was somehow lost and has never undergone modern analysis. As such, there is no current evidence of an impact in the form of meteorites.
That changes today with the extraordinary announcement by Andrei Zlobin from the Russian Academy of Sciences that he has found three rocks from the Tunguska region with the telltale characteristics of meteorites.
If he is right, these rocks could finally help solve once and for all what kind of object struck Earth all those years ago.
Zlobin’s story is remarkable in a number of ways. The area of greatest interest for meteor scientists is called the Suslov depression, which lies directly beneath the location of the air blast and is the place where meteorite debris was most likely to fall.
Dig into the peat bogs here and you can easily find layers that show clear evidence of the explosion. Zlobin said he dug more than ten prospect holes in the hope of finding meteorite fragments, but without success.
However, he had more luck exploring the bed of the local Khushmo River, where stones are likely to collect over a long period of time. He collected around 100 interesting specimens and returned to Moscow with them.
This expedition took place in 1988 and for some unexplained reason, Zlobin waited 20 years to examine his haul in detail.
But in 2008, he sorted the collection and found three stones with clear evidence of melting and regmalypts, thumblike impressions found on the surface of meteorites which are caused by ablation as the hot rock falls through the atmosphere at high speed.
Zlobin and others have used tree ring evidence to estimate the temperatures that the blast created on the ground and says that these were not high enough to melt rocks on the surface. However, the fireball in the Earth’s atmosphere would have been hot enough for this.
So Zlobin concludes that the rocks must be fragments of whatever body collided with Earth that day.
Zlobin has not yet carried out a detailed chemical analysis of the rocks that would reveal their chemical and isotopic composition. So the world will have to wait for this to get a better idea of the nature of the body.
However, the stony fragments do not rule out a comet since the nucleus could easily contain rock fragments, says Zlobin.
Indeed he has calculated that the density of the impactor must have been about 0.6 grams per cubic centimetre, which is about the same as nucleus of Halley’s comet. Zlobin says that together the evidence seems “excellent confirmation of cometary origin of the Tunguska impact.”
Clearly there is more work to be done here, particularly the chemical analysis perhaps with international cooperation and corroboration.
Then there is also the puzzle of why Zlobin has waited so long to analyse his samples. It’s not hard to imagine that the political changes that engulfed the Soviet Union in the year after his expedition may have played a role in this, but it still requires some explaining.
Nevertheless, this has the potential to help clear up one of the outstanding mysteries of the 20th century and finally determine the origin of the largest Earth impact in recorded history.

Numerous scientific expeditions failed to recover any fragments that could be attributed conclusively to the object.
Hundreds of microscopic magnetic spheres have been found in the 1950s and 1960s in Tunguska soil samples, but there is continuing debate about whether they are the remnants of a vaporized meteor.
“There’s really not much out there, and nothing that’s definitively Tunguska,” says Phil Bland, a meteorite expert at Curtin University in Perth, Australia.
The lack of samples has allowed wild speculation about the cause of the event, with some of the more esoteric explanations invoking antimatter and black holes.
But most geoscientists think that part of an asteroid, or perhaps a comet, broke away and fell to Earth as a meteor.
Now, researchers led by Victor Kvasnytsya at the Institute of Geochemistry, Mineralogy and Ore Formation of the National Academy of Science of Ukraine in Kiev say that they have found a smoking gun.
In what Kvasnytsya describes as the most detailed analysis yet of any candidate sample from the Tunguska event, the researchers conclude that their fragments of rock — each less than 1 millimetre wide — came from the iron-rich meteor that caused the blast.
The study was published late last month in Planetary and Space Science1.
“If these are Tunguska fragments, it could end any doubt that it was an asteroid impact,” says Gareth Collins, an Earth-impact researcher at Imperial College London. “We would have convincing proof that this was an extraterrestrial event, and it would rule out a comet.” ...”

meteor (n.)
late 15c., "any atmospheric phenomenon," from Old French meteore (13c.) and directly from Medieval Latin meteorum (nominative meteora), from Greek ta meteora "the celestial phenomena, things in heaven above," plural of meteoron, literally "thing high up," noun use of neuter of meteoros (adj.) "high up, raised from the ground, hanging," from meta "by means of" (see meta-) + -aoros "lifted, lifted up, suspended, hovering in air," related to aeirein "to raise" (from PIE root *wer- (1) "to raise, lift, hold suspended").
We know that "meteoric rise" refers to speed not direction, but because meteors fall, the phrase appears humorous, contraditory. Even the above etymology decribes a falling object in terms of rising.
The Hebrew word not only reflects its foreign origin (no pun intended), it ends up as a hybrid portmanteau of Gr. meta [מטא] + Heb. ohr [אור]. A meteor appears as a rod or staff of light, a mate ohr [מטה אור], also similar to the phrase mot ohr [מוט אור].
מטאור
metadata: data from data ---> meta-ohr: light from light
meta-
word-forming element of Greek origin meaning 1. "after, behind; among, between," 2. "changed, altered," 3. "higher, beyond;" from Greek meta (prep.) "in the midst of; in common with; by means of; between; in pursuit or quest of; after, next after, behind," in compounds most often meaning "change" of place, condition, etc.The Beta Taurids (ß–Taurids) are an annual meteor shower belonging to a class of "daytime showers" that peak after sunrise.

2019 will be the closest post-perihelion encounter with Earth since 1975. The Taurid swarm is expected to pass 0.06 AU (9,000,000 km; 5,600,000 mi) below the ecliptic between June 23 – July 17.[5]
During 2019 astronomers hope to search for hypothesized asteroids ~100 meters in diameter from the Taurid swarm between July 5–11, and July 21 – August 10.[6] There is circumstantial evidence that the daytime June 30 Tunguska event came from the same direction in the sky as the Beta Taurids.[6] The next June close approach to the Taurid swarm is expected in 2036.[7]

meta [מטא] = 50
The 50th anniversary of the Apollo 11 moon landing is July 20th, the 17th of Tammuz. The Torah portion is Balak, in which falling is a vision of rising:
Num 24
16. The speech of one who heard the words of God, and knew the knowledge of the most High, who saw the vision of the Almighty falling, but having his eyes open [revealed]:
17. I shall see him, but not now; I shall behold him, but not near; there shall come a star out of Jacob, and a scepter shall rise out of Israel, and shall strike the corners of Moab, and destroy all the sons of Seth:
The key elements as the literal words on a letter grid (the word kokav coming out from the word Yaakov, the word shevet rising from the word Israel, Mashiach from Israel et al) are all found in a letter chart of Gen 32, in multiples. All the same chapter where Israel first appears in the Torah. You can set up a grid based on kokav at a skip of 45.
What's funny is that the place where a shevet (-35) arises from Israel (101) is on the name Esav (v.14). It's a simple letter chart. Bummer most people don't care. One word in particular stands out because it displays as multiple "meteors". Discover the unknown..
The earth has never nor will ever be in the same part of space that it has been in in the past. The entire solar system is being drug along in the suns gravity wake whilst it orbits the center of the galaxy.
Time travel is impossible for this reason. The old clock tower in the city square of Hill Valley just aint where it used to be!
Constipation clinic?
...and the whole galaxy itself is expanding outward also? Have the astrophysicists pinpointed the section of the universe where the cosmic egg exploded into being? One would think that all we gotta do is track the expansion paths of all the galaxies and extrapolate back to the point of origin...no?
