Imagine a project at Harvard to convene the greatest scholars in every field over a period of several hundred years in order to create an encyclopedia of their collective knowledge. Who wouldn't want to see the final product?
This is the Talmud: a unique collection of wisdom that would surprise experts in any discipline, including law, ethics, psychology and economics. In the realm of cosmology, too, the Talmud makes assertions -- sometimes literal, sometimes metaphoric, and sometimes both.
To give one example, consider the Talmudic estimate of the number and distribution of stars in the universe.
The vast bulk of Talmudic wisdom is transmitted from Moses.
In order to appreciate this passage, bear in mind two things. First, the vast bulk of Talmudic wisdom is claimed to be a transmitted tradition, from Moses to Joshua, to the prophets, to the Elders, to the Great Assembly, and then to a chain of scholars until the completion of the Talmud 1,500 years ago. Hence it is called the Oral Law.
Second, we need to appreciate the limitations of science 1,500 years ago: the telescope was invented in the 16th century, and the number of stars visible to the naked eye is approximately 9,000.
So what did these ancient rabbis say about the number of stars? In Tractate Brachot, page 32b, the Talmud records a tradition, in the name of Rabbi Shimon ben Lakish, that there are roughly 1018 stars in the universe. This number is remarkably big and much closer to the current scientific consensus of 1022 than common sense would allow.
Now, although it is interesting for an ancient people to have such a large estimate, this single coincidence could perhaps be explained as an extremely lucky guess. Never mind that no other ancient people had an estimate anywhere near this order of magnitude, nor did they have a conventional way to write such a number. (I have queried dozens of astronomers and none could identify a single other ancient culture with remotely similar numbers.)
Multiple Patterns
However, the Talmud relates more than a raw number. The passage explains that the distribution of stars throughout the cosmos is neither even nor random. Rather, it states that they are clustered in groups of billions of stars (what we call galaxies), which themselves are clustered into groups (what astronomers call galactic clusters), which in turn are in mega-groups (what we call superclusters).
To describe the stars as clustered together, both locally and in clusters of clusters, was far beyond the imagination and the telescopes of scientists until Edwin Hubble's famous photographs of Andromeda in the 1920s. Galactic clusters and superclusters have been described only in the past decade or so. Moreover, the Talmud states categorically that the number of galaxies in a cluster is about 30. And wouldn't you know it, astronomers today set the number of galaxies in our own local cluster at 30!
The consensus of astronomers is pure astonishment.
Further, the Talmud adds that the superclusters consist of about 30 clusters each, and that superclusters are themselves grouped into a bigger pattern of about 30 (megasuperclusters?) of which the universe has a total of about 360. Thus, the Talmud appears consistent with one major theory that the overall structure of the universe is shaped by the rules of fractal mathematics. I've shown this data to numerous astronomers around the world and the consensus are pure astonishment.
Could it be that Rabbi Shimon ben Lakish made an extremely lucky guess? That might be plausible if he had used a number that had symbolic significance in Judaism, such as seven, 10, 18 or 40. What is the significance of the number 30? To my knowledge, there is no spiritual or religious reason for choosing that number. It therefore seems to be exactly what it claims to be: a conscientious oral transmission of a received tradition, rather than simply one person's guesstimate.
Moreover, Rabbi Shimon had a reputation for impeccable honesty; it is unthinkable that he would have invented these numbers or guessed without telling us so. The clear intent of the passage is to convey an oral tradition.
You are now in on the secret of Shavuot: There is something special about the Torah (and rumors of its demise have been greatly exaggerated!). The Torah is much, much more than a mere "cultural expression" of one tiny group of ancient people, so numerically small that we reminded Mark Twain of a "nebulous dim puff of star dust lost in the blaze of the Milky Way."
This passage about the stars is a mere five Talmudic lines, itself about as significant as a puff of star dust. But it also hints to the treasures available to those who seek them. Shavuot is a great time to begin.

calculation in talmud seems to come out to 10^14 not 10^18
Thank you Rabbi Seinfeld. This was a very interesting article.
Based on the the gemara in berakhot 32b the calculation seems to be:
12*30*30*30*30*30*365,000 = 1.06434e 14 (about 10^14 or 100 trillion)
"The Holy One, Blessed be He, said to Israel: My daughter, I created TWELVE constellations in the firmament, and for each and every constellation I have created THIRTY armies, and for each and every army I have created THIRTY legions [ligyon], and for each and every legion I have created THIRTY infantry division leaders [rahaton], and for each and every infantry division leader I have created THIRTY military camp leaders [karton], and for each and every military camp leader I have created THIRTY leaders of forts [gastera], and on each and every leader of a fort I have hung THREE HUNDRED AND SIXTY-FIVE THOUSAND stars corresponding to the days of the solar year. And all of them I have created only for your sake; and you said the Lord has forsaken me and the Lord has forgotten me?"
Of course, I may be missing something here but I've checked several times and I keep getting the same answer (10^14). I have no idea how 10^18 was calculated, any clarification would be much appreciated.
While 10^14 is of course a very large number it is not 10^18 nor is it particularly close to the current 10^22 number science has estimated.
Would love some more clarity on the topic,
Thanks

Correct calculation
Number of stars per the Gemara: 12x30x30x30x30x30x365x1000x10000 (alfei ribo) = approx 10^18

To say that Rabbi Shimon ben Lakish is wrong because his numbers do not exactly coincide with current Science numbers is nonsense. Current science numbers are mathematical approximations and they will change as our observational apparati and computational abilities improve. A hundred years ago science thought the entire universe was the Milky Way. Your point that Archimedes was capable of expressing even larger numbers was a correction to the article, and I thank you for it. I have ordered a copy of "The Sand Reckoner". But even the great Archimedes had no idea there were billions of stars in billions of galaxies. That bit of knowledge, which was passed down via the oral tradition nearly 3000 years ago, was only discovered by Western Science less than 100 years ago. I find that fact quite remarkable.

Robert''s subject line is baffling. "Archimedes Merely Observes Space and Time!" Doctors Merely Observe Patients'' Conditions! Engineers Merely Observe Correct Construction Techniques! There is a lot to be said for correct observation, especially when it conflicts with dogmatic pronouncements, such as... "Talmud Reveals It By Authority!" Yet anyone who reads R. Seinfeld''s article will note that even he admits that R. Lakish''s estimate was INCorRECT. In the REAL world, we don''t build bridges and spaceships based on incorrect dogmatic pronouncements, but on the observations of "Ph.D.''s and astronomers". The rabbis of the Talmud wrote that the Torah is written in the language of man. In their wisdom, they understood that the Torah is not a scientific textbook, and neither is the Talmud.

Uhh?
"In their wisdom, they understood that the Torah is not a scientific textbook, and neither is the Talmud." I guess that the necessary conclusion from this statement is that findings in scientific journal's are written in the language of the divine? Try again. Oh and BTW, we don't build bridges based on the numbers of stars in the universe, your statements are irrelevant to the discussion, we aren't trying to deny the observational sciences, we are just tired of the secular world worshiping scientific methodology over ontology.
Nickick, November 5, 2016 5:35 AM
Sorry Mr. Switkay , i have to agree with Mr. Roberts. Nasa did recently re - calculated their number of stars. Meaning it is due to change as time goes on.. The Calculation Nasa uses are due to error that is due to observation of guessing not of ACTUAL count.. So again The Jewish Bibles are still standing firm as science seems to change.. here's an idea, How do we know Science of chemistry exist ? Through the results we see not that we see the subatomic itself but the results of it.. Hence with God it is the the world around us we observe there is something beyond logic..

Archimedes Merely Observes Space and Time! Talmud Reveals It By Authority!
PH.D''s and astronomers provide but a glimpse of the observable. The Talmud reveals both what we observe in a physical world and the universe within.

Archimedes named a larger number earlier
Sorry to have to refute a false statement, but truth is more important. Above, you say "Never mind that no other ancient people had an estimate anywhere near this order of magnitude, nor did they have a conventional way to write such a number. (I have queried dozens of astronomers and none could identify a single other ancient culture with remotely similar numbers.)" The latter statement is false. In "The Sand Reckoner", Archimedes (287-212 BCE) gave notation for the number 8 times 10 the 63rd power, much larger than the number in the Talmud. Archimedes gave a consistent systematic notation for large numbers eight centuries before the completion of the Talmud. The astronomers cited above must have been unaware of this well-known work of mathematics.

Response to Hal
You are right about notation being an element of the ancient mathematics. But let us think about the difference between what our friend Archimedes was trying to express and what our Rabbi's were saying. Archimedes was calculating the number of grains of sand that would be contained within the "celestial sphere" as it was known. The rabbis on the other hand were presenting something totally different, the number of stars in the universe. Archimedes was calculating volume, he was obsessed with volume, and the order of objects and shapes, lines, angles etc. Also, he only wrote one treatise on astronomy, the Sand reckoner as you mentioned. The rabbis by contrast by were not only presenting a number related to the number of STARS, not grains of sand, they were either knowingly, or unknowingly, ignoring the "wisdom" of the Greeks who postulated a rather annoying system of wheels and spheres, and "epicycles" to explain the heavens, all of which is made irrelevant by the Rabbi's statement that there exist 10^18 stars in the universe, expanding the size of the universe far beyond that even dreamed by the greeks, or even 17th century astronomers. Apparently oral tradition was about 2000 years ahead of Greek observation. Another thing, it wasn't until recently that the idea that the universe had a beginning was scientifically accepted. In fact it was a scientific statement of faith, after newton, that it had neither beginning nor end. As far as a beginning of the universe is concerned, the Greeks rejected it, Newton's infinite mass points sustained this view, and those pesky Jews advanced it declaring that not only does it have a beginning but it has a purpose. And lo and behold, here we are in 2011 and the most well established theory in science, the big bang, the big beginning, reigns. Hal, next time, just appreciate the intensity of thought, and the clarity of conviction that these rabbis had before nit picking at an almost irrelevant incorrect statement.

True,but even Archimedes was not discussing at all the number of stars,but number of grains of sand,-so there is uniqueness to the Talmudic estimate of number of stars

Fantastic article. Where in the Talmud is this stated? Thanks

Re: Archimedes
The comment about Archimedes is based on a misunderstanding. My statement that "no other ancient people had an estimate anywhere near this order of magnitude" is referring specifically to estimating the number of stars, not to mathematics in general. It doesn't take advanced science to imagine incredibly large numbers of things, but we know of no one in the ancient world, aside from the transmitters of Oral Torah, who conceived of such a vast cosmos.
(8) YH, June 12, 2008 11:18 AM
and G-d?
I found the article interesting though I'm a bit taken aback by the omission of G-d!
"...the vast bulk of Talmudic wisdom is claimed to be a transmitted tradition, from Moses to Joshua ..."
And where did Moshe receive the tradition from?
The Talmud is not merely a compilation of the wisdom of the Sages. The Talmud, as the Oral Torah, was transmitted by G-d to the Jewish people at Sinai, along with the Written Torah.
Yes, the Torah is special, as the author stated, but how strange that he didn't say what makes it special, i.e. that it contains G-d's wisdom.
p.s. I'd like to hear what the author's response is to the comment about Archimedes.

Number 30
The number 30 is no mystery to me. The number 30, in ancient times, was the age of emancipation of a Jewish male. These stars are within their families. The number 30 represents a family unit. Shalom

The number 7
The number 7 which is the most prominent number in the Torah does appear in this gemara. The GEmara describes 7 levels, (from bottom up) stars, gastra, karton, rahaton,leegyon,chayil, and mazalot.
Thanks

The numbers 12, 30, and 365 that he uses are common Sumerian numbers, aren''''t they? The ones who made up the circle''''s 360 degrees and 12 hours with 60 minutes each? The sages of the Talmud were well-versed in the science of astronomy of its time.
It does add up to a rather large number - but what''''s important is Reish Lakish''''s point that G-d created all of them for us, and will never forsake the Jewish People.
(1) Emanuel, June 1, 2008 2:50 PM
Interesting Indeed
Even the self-hating, skeptical/atheistic Jews cannot respond to this. But still, we have to keep in mind that "Rabbonan lo aswotho nineihu" (''Our rabbis were no physicians'', as Rav Sherira Gaon wrote). Our Sages of blessed memory transmit the word of G-d, namely the meaning of reality and not reality itself. The task of describing reality is left in the hands of the skilled scientists.
And so, if the number of stars was kept though tradition, it had to have some "nafka mina" (practical implication).
