half right half wrong, axis precesses in, not stars; so since precession means to go forward, seasons slip backward, stars do not precess forward. Spring season slipped back from March 20 to March 10, the stars of March 10 is not a sphere that moved forward to March 20.

There are a few problems with this. 1. The gravitational model has so many problems, it’s difficult to harmonise it even with the moon being where it is or behaving as it does. The wobbel is an assumption, there can be other reasons for the apparent precession. Certainly, things have to be simplified, but is quite a crime of omission. Especially as all statements are made as if ascertained fact, which they aren't at all. 2. At least one star, namely Sirius, seems not to take part in this, which cannot be explained by the cuttent theory. 3. It was not H. who first observed precession. In fact, he didn’t. We know that, bc he gives no measurements by himself. If you read his numbers carefully, you’ll notice, that they correspond to observations made in Mesopotamia and Egypt. Neugebauer sadly declared that the Ancient Babyloninans did not no precession. We today know that this is quite wrong. They did. And so did the Egyptians. They used Sirius, however, that barely moves, precisely bc it’s an exception. 4. Astrology very weak. If you use the Sidereal system, the sun is not in Capricorn at New Year, but in Sagittarius. Only in the Tropical system it’s still in Capricorn. 5. Caesar got his calendar fixed by Egyptians he brought back to Rome 6. Your take on Astrology is embarrassing. I hope you do know a bit more about Astronomy than the nonsense you say about Astrology. Really, even the basis is incorrect and even for those believing in astral determinism (very few do) your statements are off.
1. The gravitational model is solid. I don't know what issues you're talking about. 2. Sirius precesses like all the other stars: astronomy.stackexchange.com/questions/45442/is-the-claim-that-the-star-sirius-does-not-precess-like-other-stars-true Yes, I was having some fun with astrology, but my horoscope seems pretty accurate.
Indian Vedic scriptures Vedanga jyotisha and surya siddhanta 1400 BCE already mentions it. But just the difference is in the cycle. They mentioned 25,700 year instead of 26,000 year. It also mentions Abhijit will be the new pole star in 14000 AD.
The ancients recorded the cycles. Copernuis then Newton gave it a physical explanation (which is wrong but still taught as a fact). I do wonder if and HOW the ancients understood it better than we do. We fudge the math equations out of observations and they still don't work.
Worth clarifying: the Zodiac he refers to is the Sidereal Zodiac, used mostly in the East by Vedic Astrology rather than Western, though some Astrologers of the West have begun to look at this Zodiac. Most Astrologers in the West refer to the Topical Zodiac, which is Seasonal rather than based on the Constellations (as he mentions!) The Tropical Zodiac is fixed to the solstices and equinoxes and is unchanging with time. This means that Aries, for example is defined by the first 30° of the ecliptic following the vernal equinox, Cancer the first 30° following the Summer Solstice, Libra the first 30° following the Autumnal Equinox, and Capricorn the first 30° following the Winter Solstice. Aside from this, the Zodiacal Signs are 30° of the ecliptic each. The Constellational boundaries we know today, even if they had been the exact same as they were 5000 years ago, would be far different. Virgo is the largest Ecliptic Constellation encompassing almost 14% of the Ecliptic, whereas Scorpius (the Constellation of the Sign Scorpio) is less than 2% (approximately). The constellations were used in ancient times as reference points to the Signs, but they are not the Zodiac itself. The separation between Sidereal and Tropical astrology occurred in the years following the discovery of the precession, and remains in place today. Sidereal and Tropical Astrology both have their benefits in terms of self discovery, but are very different practices.
Cosmic motions in all their complexity are so ludicrously complicated, I cannot stop wondering how physicists responsible for cosmic probes, rockets and similar stuff get their calculations right most of the time.

Joel Harris But Polaris isn't very far away. I have a hard copy star chart from 1900. And in the textbook there is a short comment on the declination of Polaris is increasing. In 1900 Polaris was 1.15° from north. Today Polaris 0.73° from true north. Well the chart is now visibly different. Polaris is closer, and in 2050 it'll be at its minimum of 0.5°.
This is a weird comment. Astrology is just the language of the celestial skies. The amount of people who think it's like a religion to believe in as opposed to a tool to illuminate, like a philosophical school of thought, is disturbing.
Yes measured from global Flood 2370bc, at Babylon 1626bc as 6 days in 744 years.

Yes i observe the sun set more north in summer and more south in winter. Plus the big dipper is visible when i open my door. In summer it appears at night handle up n dipper down in beginning of night and rotates handle to left and levels out late night. In winter it is appearing level handle on left. And rotates handle down late at night.
This is also the reason for the Sahara desert. The Sahara desert changes from a desert to a marsh wetland depending on the wobble of the earth. That means the Sierra desert will be green again someday. Unfortunately none of us will be alive to see it. Perhaps in generations to come and man hasn’t destroyed himself humans will see the desert become green again.

Polaris is currently only about 0.75 degrees from the north celestial pole. It is the 49th brightest star in the sky. It turns out that having a pole star with this level of quality is rare. I did a lot of math on this and found that the probability of having a better pole star is only about 2% for the north pole or 4% for either pole. The details of these numbers follow. I defined the quality of a pole star as 1 / (rank * angle from pole * angle from pole). So the quality of Polaris is 1 / (49 * 0.75° * 0.75°) = 1 / (49 * 0.013 * 0.013) = 119.1 I got the probability of having a better pole star using the following code. It simulates random placement of 5000 stars for each simulated planet. It counts what portion of the planets have a pole star with better quality than Polaris. You can run this code in the inspector console in a desktop web browser. You can control various simulation parameters by changing the last line. Currently it outputs the probability of having a better pole star at either pole. const NUM_STARS_LIMIT = 5000; // The number of stars visible to the naked eye is about 5000. const POLARIS_DISTANCE_FROM_POLE_DEGREES = 0.75; const POLARIS_RANK = 49; function getProbabilityBetterThanPolaris(num_rounds, include_both_poles, quality_function) { // num_rounds: the number of rounds to run to get the probability. Go at least 10000 for accuracy. // include_both_poles: boolean // if true, stars near either pole will be considered // if false, stars near only one pole will be considered even though stars in both hemispheres are included in the ranking of stars // quality_function: (rank, radius_squared) => Number // This function is called for each star. // The higher the number, the better the star is as a pole star. const polaris_quality = quality_function(POLARIS_RANK, Math.pow(POLARIS_DISTANCE_FROM_POLE_DEGREES * Math.PI / 180, 2)); let num_rounds_with_better_pole_star_than_polaris = 0; for(let round_index = 0; round_index < num_rounds; round_index++) { let found_better_pole_star = false; for(let star_index = 0; star_index < NUM_STARS_LIMIT; star_index++) { let x = 0; let y = 0; let z = 0; let distance_squared = 0; while(x*y*z === 0 || distance_squared >= 1) { x = (Math.random() * 2) - 1; y = (Math.random() * 2) - 1; z = (Math.random() * 2) - 1; distance_squared = (x*x) + (y*y) + (z*z); } // is now guaranteed to be in the unit sphere. // Also, x, y, and z are guaranteed to be nonzero. if(include_both_poles || z > 0) { const quality = quality_function(star_index + 1, ((x * x) + (y * y)) / (z * z)); if(quality >= polaris_quality) { found_better_pole_star = true; break; } } } if(found_better_pole_star) { num_rounds_with_better_pole_star_than_polaris++; } } return num_rounds_with_better_pole_star_than_polaris * 1.0 / num_rounds; } console.log(getProbabilityBetterThanPolaris(10000, true, (rank, radius_squared) => 1 / (rank * radius_squared)));
Procession is about 1° / 72 years.... But that's not why the Julian and Gregorian calendars are inaccurate. They're just not accurate. The year (neither sidereal nor tropical) is not evenly divisible by whole days. Either solar noon shifts every day, or we add/subtract days every few odd years, irrespective of the zodiac.
The Axial Precession was discovered by pre-dynastic Egyptians. The Pyramid Code is a 5 part documentary with an indigenous Egyptian Hakim Arywan, a historian & wisdom keeper explains about the Dark Age/Golden Age 26K year cycle. The documentary also introduces the Dogon people who were also speaking of it and Sirius long before we had telescopes to prove it.
Great video! Thanks for the explanation. Only one remark: It seems like you mentioned Hipparchus had discovered that the Earth's axis is moving. However, there are many sources which suggest that this phenomenon was discovered much earlier in India.
Very interesting. I came here bc something is off. Either our calendar, or our calculations, or the precession is changing speed. I have been been becoming aware of it over a year now. Today, Jan.2, 2021, it is darker, at an earlier time, than it was on Dec.21. Guaranteed. I'd like to know what's going on. :) peace
The rate of precession is changing. They don't have an explanation and I wouldn't take whatever they pull out of their butts as to why seriously. The earth doesn't wobble because the entire solar system is doing it.
The earth has been " wobbling " on its axis for millennia. It's just so slow and occurs over the millennia, we never notice it. Seasonal changes happen +/- and that's it. Spin a top on the floor, it wobbles as it slows too. Same thing.
This video is amazing. Thank you! The ending had me almost falling off my chair laughing! 😂 I'm using this in an astronomy course I'm teaching thank you!
@@ItsJustAstronomical The Egyptians encoded the dimensions of the earth into the dimensions of the pyramids. They could not have done so without knowing of the earths procession. The great pyramid is almost perfectly aligned to true north. There are so many clues that mainstream archaeologists ignore that show the ancients knew exactly what we know today if not more.
I like your light-hearted projection, and historical record-based approach to this! Thanks. A compact (short) lecture, makes me stay awake and pay attention. Are you a high school physics teacher?
Absolutely phenomenal video! Besides the correction on why axial precession happens (which you already corrected) you forgot that due to axial precession, the constellations are already about a month off, scorpio isn't around November (it was around 1 ad) now it is around december... Meaning around 15,000 ad geminis will be born around January, yes you probably read the wrong horoscope your entire life... Astrology is complete nonsense.
The ending was amazing, but I do have a question. Is astrology accurate? Now of course I don't mean accurate in predicting your future, is it accurate in saying that I am a sagitarius because I was born between november 23 and December 21? If the earths position relative to the stars moves ever so slightly shouldn't that date change at least a day during a human lifetime? Not to mention, when were the zodiac dates decided? As far as I know they could've been set in stone 400 years ago and by this point we are truly facing Sagittarius in January or something.
You're totally right. They were set a long time ago and they are slightly off from when they were originally set. This article explains more: www.livescience.com/4667-astrological-sign.html
Just leaving out the fact that the earths "wobbling" does only affect the stars and not the other planets. Does that mean that the whole system "wobbles" after the earth?
The earth doesn't wobble but yes the entire solar system is actually precessing. Some of the stars are rising with us too. This is impossible in the standard model theory.
A paper shows that the axial precession (or precession of the equinoxes) is since the entire Solar System disk is spinning (from 2021): article.sapub.org/10.5923.j.astronomy.20211001.01.html
It almost made me cry. All the educations I had 'suffered' from the schools were the torture compare to this vid. It is amazing. Thank you Thank you Thank you.
Nothing new--in AD 325 at the 1st Ecumenical Council of the Orthodox Church of the Roman Empire, the Spring Equinox fell on 25 March; during the discussions about the formula for calculating the date of Holy Pascha each year, the Holy Fathers agreed on "the first Sunday after the first full moon after the Spring Equinox" at which point the Pope of Alexandria pointed out that the sun had crossed the equator that year on 21 March, so that phrase was added to the kanon, and ever since that has been the date of the Spring Equinox. No doubt at some point in the future it will have to be revised once again.
There's also like Lilith which I'm sure they're using-a true north and a node North, which means Polaris is not actually true North star. If I'm not mistaken I think it may be Sirius or something like that I don't remember.
I have a two questions. The sun travels about 500,000 miles per hour (804,672 km) towards the star Vega. This was recently noted after astrophysicists discovered the shift in the light spectrum that occurs with distant galaxies. Like the Doppler effect that occurs with sound a similar thing happens with light. Thus astrophysicists are able to deduce the speed and rotation of distant galaxies, stars and the direction that they are moving, i.e., towards or away from us. The more the light shifts in certain wavelengths the faster the distant object is traveling. Thus they were able to deduce the speed of 500,000 mi/h that our sun is traveling through the Milky Way. My question; is the sun's movement included in your presentation of the precession? Because I believe this movement would explain why the constellations retrograde 1° every 72 years. In 72 years the sun would have traveled 315,576,000,000 miles (507,870,342,144 km), about 1/18 the distance of a light year. The Earth returning to the same position (tropical year) year after year while the axis remained stationary, wouldn't the distance the sun traveled in 72 sidereal years, from Earth's perspective, cause the constellations to appear to retrograde 1°? It would be cool if you did a simulation from an outside perspective that included the Earth's orbit and rotation along with the sun's orbit and rotation against the background constellations over time.
I've read that the math to calculate procession is simpler if we consider our sun being part of a binary system. In that model, procession occurs due to the elliptical orbit of the sun around the barycenter of this larger system. But would the distance the sun moved be enough to explain procession? If this were the case, wouldn't we be able to calculate the sun's orbit and determine the angles and direction necessary to calculate where the companion star is? Why wouldn't we have found this companion by now (even if it's a dim brown dwarf)? But cool things to think about.
I agree with you. There needs to be another factor that is not addressed. According to the Mayan Indians and their Codex, the solar system is bobbing up and down along the galactic ecliptic, z direction as it orbits the galaxy's core. The sun takes on a snake like motion as it travels through the galaxy. Hence the depiction of a snake when referring to the sun's motion. They mentioned the dark rift along the galactic ecliptic being the measuring stick, so to speak for their great Maya calendar and how the solar system moved long before astrophysicists discovered the sun was even moving. So the extra variable to cause this precession of the equinoxes would be the bobbing motion in the z direction that occurs to the sun over time while it orbits the galaxy's center. the sun moves to the north and then moves back towards the south on 12,960/2 = 6,480 year intervals. Besides, the star Vega is to the north, the constellations around the Earth are on a different plane than the direction the sun is moving. Thus why this z movement is causing the sidereal year to change while the tropical year remains the same.
I’m just curious why people spend so much time measuring the apparent movement of the stars as it relates to the wobble of the earth. There must be some significance to the positions since apparently statues of the constellations were built. How long ago did the Sphinx look at itself on the spring equinox? Six constellation positions taking 2,160 years per constellation would indicate 12,960 years? What was happening at that time? Did they just want whoever followed to know when they were they? Who were they? Where did they go? What happened to them? Don’t tell me they were aliens. I think space travelers would have better ways to spend their time than building stone buildings.
been trying to wrap my head around sidereal time and the visual helps. actually, it helped to clarify astrological concepts too: the vedic system of astrology (from India) is based on the constellations and uses sidereal time. however, western astrology (where pop culture horoscopes and what not come from) is based on the seasons and uses tropical time. the stars in the sky at the time of development were simply the label given. for example, aries is aligned with spring (forget about the aries constellation). aries is the fresh spark of spring energy that begins processes. So don't worry -- scorpios will still be those born in late october/november (dark, brooding, going into the underworld autumn) even when the sun is in scorpio the constellation in april :) the real mind fck with western astrology is the northern and southern hemispheres (opposite seasons)--so the energies are all wrong.
Good vid, but please point out how the 26 mile equatorial bulge is only one-thousandth the size of the Earth's circumference, so the Earth is just as spherical as a billiard ball.
It isn't as spherical as that. It does not spin like a homogeneous sphere would, and this is easily tested by measuring the moment of inertia. That measurement clearly indicates how the earth wobbles in its axis, because it doesn't spin like a homogeneous sphere would. It tells us that mass is distributed differently as varying locations on earth
That kind of explained my question: Is this means that along with precession, seasons are also slightly shifting possition around the sun? If so, then after some thousands of years we would see stars that now could be seen in winter, we will see them in summer? Im not sure if anyone would understand my question.
That's exactly right. The seasons will happen when the earth is at a different point along its orbit. So in 13,000 years, the earth will be on the opposite side of the Sun during summer. So stars that were visible in the winter will be visible in the summer in 13,000 years.
@@cosmoanayiotos6924 11,500 years ago it was the end of the fourth Glacial Era and the end of the Paleolithic Period. Men were making very refined stone tools, they knew art (plenty of cave paintings and graffitis, bone and ivory figurines), they buried their dead with their belongings, they wore jewelry, they hunted very big preys (so they must have had a good social organisation)... not at all "animals", you little ignorant.
If you take the most precise wind up watch and set it to the exact time of you're cell phone, over time you lose time comparing the two. Could the last largest tsunami that we had slowed the Earth's rotation that much? Also, could the Earth's wabble be the actual reason for climate change more than anything else?
There are no wrong questions: It would be interesting to calculate the precession values of all planets and our sun. If there is. I don't know. Maybe our whole solar system is sort off wobbling together.
Check out Hamlet's Mill and Graham Hancock. The precessional has been recorded and known for much, much longer than 2nd Century BC. -Old Kingdom Egypt -Maya -Norse Mythology Etc. Good explanation.
It's a wrong explanation. There's no wobbling. I've been meaning to read Hamlet's Mill because I'm curious if the ancients did actually understand it better. Modern astrophysics is trash.
The average amount of light would be about the same, but there's a positive feedback loop as discussed in my Ice Age video that complicates the matter.
Great post. Yes the earth is wobbling..What is causing it?...Planet X is a giant magnet...bigger than Earth which is a magnet as well. What happens when you move a huge magnet close to a smaller one...the smaller magnet moves and spins around .
Where is planet X? So far away it cannot be observed by telescope? So don't expect any measurable effect on earth by the magnetic field of such a distant body.
so if we have been using the Gregorian calendar or even a tropical method for keeping years that would mean our windows of signs has fallen out of line? Even since we adopted the Gregorian calendar we've moved 6 days behind the astrological frames.
Megalithic structures are lined up with certain stars. If procession moves 1 degree every century then they know exactly how old the sphinx is. Why do they lie about not knowing?
Everything matters, has a purpose, has a meaning. I was thinking today about how the earth axis rotated every so 20,000 years and how it relates to zodiacs. Now 5 mins ago I was thinking wtf is a precession asked Siri bc of thinking thoughts and intuition and curious. Now I’m here watching this video about precession of the earth. Follow your intuition curiosity and intellect!!!
Ahh, tropical year, I forgot it was the tilt that governs the seasons, not the orbital position. Now precession makes sense in terms of the sun's position. (thank god, that was annoying me) So that means the equinoxes slide between perihelion and aphelion every 13000 years.
It does affect the climate over very long periods of time. It's not causing much of any change over the past 100 years. This video explains more: th-cam.com/video/iA788usYNWA/w-d-xo.html
Are you sure? I've just watched a video explaining that this isn't true. Precession requires that one end of the axis is fixed, and that's not the case with the Earth.
I made a mistake in this video. I made another video to correct my mistake: th-cam.com/video/-QT1rsr9U44/w-d-xo.html

Well the chart is now visibly different. Polaris is closer, and in 2050 it'll be at its minimum of 0.5°.
I’ve believed in astrology for 10 years and I’m trying to abandon it bc I realize it’s been hurting me. This video, made me feel better. Thank you 😌
If only more females would realize this sooner
Yeah it’s upsetting to see how ubiquitous it is, I feel like it seriously needs to stop.
This is a weird comment. Astrology is just the language of the celestial skies. The amount of people who think it's like a religion to believe in as opposed to a tool to illuminate, like a philosophical school of thought, is disturbing.
@@redfullmoon well its often vulnerable people who are driven to superstition. I agree astrology is bullshit, and I am glad I no longer believe in it.
looks like you never truly undestood astrology :(
Precession was known about by civilizations long, long before Hipparchus.
Yes.. Just thinking about Göbekli Tepe from 11.500 years ago!!
Yes measured from global Flood 2370bc, at Babylon 1626bc as 6 days in 744 years.
And at Egypt in 1570bc as 6 days in 800 years, where Egyptian calendar inaugurated Year 340 in 2030bc July 17 as Pamenot 1
verifying 3 days in 400 years in Egyptian dates 2030-1630bc; and Adam's 400 of his 2000-2400am (2026-1626bc).
If you learn something new, it was a worthwhile day.
Yes i observe the sun set more north in summer and more south in winter. Plus the big dipper is visible when i open my door. In summer it appears at night handle up n dipper down in beginning of night and rotates handle to left and levels out late night. In winter it is appearing level handle on left. And rotates handle down late at night.
This is also the reason for the Sahara desert. The Sahara desert changes from a desert to a marsh wetland depending on the wobble of the earth. That means the Sierra desert will be green again someday. Unfortunately none of us will be alive to see it. Perhaps in generations to come and man hasn’t destroyed himself humans will see the desert become green again.
how did that guy compared the positions of the stars, 100 years apart?
He wasn't alive before 100 years and neither the author mentioned about whom the person followed for figuring out that change.
@@Revealed2705 No. It just a made up Heliocentric story. These stories relies on majorities Ignorance.

Best animation I've seen explaining the precession
Haha! Great concept to put you standing at the pole and equator! As always great graphics and script.
The most beautiful scientific but also entertaining video I have ever seen. Of course, the exact zodiac prediction at the end also counts.
North Americans will celebrate Christmas in summer in 15,000 AD(in theory). But currently it's South Americans, South Africans, Australians, and New Zealanders which celebrate Christmas in summer.
Polaris is currently only about 0.75 degrees from the north celestial pole. It is the 49th brightest star in the sky. It turns out that having a pole star with this level of quality is rare. I did a lot of math on this and found that the probability of having a better pole star is only about 2% for the north pole or 4% for either pole. The details of these numbers follow.
I defined the quality of a pole star as 1 / (rank * angle from pole * angle from pole).
So the quality of Polaris is 1 / (49 * 0.75° * 0.75°) = 1 / (49 * 0.013 * 0.013) = 119.1
I got the probability of having a better pole star using the following code. It simulates random placement of 5000 stars for each simulated planet. It counts what portion of the planets have a pole star with better quality than Polaris. You can run this code in the inspector console in a desktop web browser. You can control various simulation parameters by changing the last line. Currently it outputs the probability of having a better pole star at either pole.
const NUM_STARS_LIMIT = 5000; // The number of stars visible to the naked eye is about 5000.
const POLARIS_DISTANCE_FROM_POLE_DEGREES = 0.75;
const POLARIS_RANK = 49;
function getProbabilityBetterThanPolaris(num_rounds, include_both_poles, quality_function) {
// num_rounds: the number of rounds to run to get the probability. Go at least 10000 for accuracy.
// include_both_poles: boolean
// if true, stars near either pole will be considered
// if false, stars near only one pole will be considered even though stars in both hemispheres are included in the ranking of stars
// quality_function: (rank, radius_squared) => Number
// This function is called for each star.
// The higher the number, the better the star is as a pole star.
const polaris_quality = quality_function(POLARIS_RANK, Math.pow(POLARIS_DISTANCE_FROM_POLE_DEGREES * Math.PI / 180, 2));
let num_rounds_with_better_pole_star_than_polaris = 0;
for(let round_index = 0; round_index < num_rounds; round_index++) {
let found_better_pole_star = false;
for(let star_index = 0; star_index < NUM_STARS_LIMIT; star_index++) {

// Also, x, y, and z are guaranteed to be nonzero.
if(include_both_poles || z > 0) {

not for long mate not for long
Just got to your channel. You are making great videos! New subscriber.
Procession is about 1° / 72 years.... But that's not why the Julian and Gregorian calendars are inaccurate. They're just not accurate. The year (neither sidereal nor tropical) is not evenly divisible by whole days. Either solar noon shifts every day, or we add/subtract days every few odd years, irrespective of the zodiac.
That wobble also effect temperature change as there is a wobble with the path of that oval shape around the sun.
The Axial Precession was discovered by pre-dynastic Egyptians. The Pyramid Code is a 5 part documentary with an indigenous Egyptian Hakim Arywan, a historian & wisdom keeper explains about the Dark Age/Golden Age 26K year cycle. The documentary also introduces the Dogon people who were also speaking of it and Sirius long before we had telescopes to prove it.
Great video! Thanks for the explanation. Only one remark: It seems like you mentioned Hipparchus had discovered that the Earth's axis is moving. However, there are many sources which suggest that this phenomenon was discovered much earlier in India.
Very interesting. I came here bc something is off. Either our calendar, or our calculations, or the precession is changing speed. I have been been becoming aware of it over a year now. Today, Jan.2, 2021, it is darker, at an earlier time, than it was on Dec.21. Guaranteed. I'd like to know what's going on. :) peace
The rate of precession is changing. They don't have an explanation and I wouldn't take whatever they pull out of their butts as to why seriously. The earth doesn't wobble because the entire solar system is doing it.
Hey.. Your videos are great and informative..
But your presentation is what really shines out 🌟🌟🌟
The earth has been " wobbling " on its axis for millennia. It's just so slow and occurs over the millennia, we never notice it. Seasonal changes happen +/- and that's it. Spin a top on the floor, it wobbles as it slows too. Same thing.
This made everything so much easier to understand.. thank you!!
This was an amazing animation and explanation thank you
This video is amazing. Thank you! The ending had me almost falling off my chair laughing! 😂 I'm using this in an astronomy course I'm teaching thank you!
0:27 I think the ancient Egyptians discovered this long before HIPPARCHUS.
That claim has been made, but there's no hard evidence to support it: en.wikipedia.org/wiki/Axial_precession#Ancient_Egyptians
@@ItsJustAstronomical The Egyptians encoded the dimensions of the earth into the dimensions of the pyramids. They could not have done so without knowing of the earths procession. The great pyramid is almost perfectly aligned to true north. There are so many clues that mainstream archaeologists ignore that show the ancients knew exactly what we know today if not more.
Simply outstanding.. Hats off sir
Watching this video was like a fever dream in the best way possible
This video is very informative. Thank you for your efforts.
I like your light-hearted projection, and historical record-based approach to this! Thanks. A compact (short) lecture, makes me stay awake and pay attention. Are you a high school physics teacher?

Woa that horoscope was remarkably accurate
Great and informative video that is easy to understand and not patronizing because I am not an Astronomer. Amusing. Enough to keep my interest.
Well done - best explanation I've ever heard for axis shift and calendar timing.
This type of content is so underrated
The last part was the most creative thing i saw this year
Absolutely phenomenal video! Besides the correction on why axial precession happens (which you already corrected) you forgot that due to axial precession, the constellations are already about a month off, scorpio isn't around November (it was around 1 ad) now it is around december... Meaning around 15,000 ad geminis will be born around January, yes you probably read the wrong horoscope your entire life... Astrology is complete nonsense.
You don't know what you're talking about
The ending was amazing, but I do have a question. Is astrology accurate? Now of course I don't mean accurate in predicting your future, is it accurate in saying that I am a sagitarius because I was born between november 23 and December 21? If the earths position relative to the stars moves ever so slightly shouldn't that date change at least a day during a human lifetime? Not to mention, when were the zodiac dates decided? As far as I know they could've been set in stone 400 years ago and by this point we are truly facing Sagittarius in January or something.
You're totally right. They were set a long time ago and they are slightly off from when they were originally set. This article explains more: www.livescience.com/4667-astrological-sign.html
WTF this video is genius!
Okay back to that assignment for my geodesy master's degree now...
Just leaving out the fact that the earths "wobbling" does only affect the stars and not the other planets. Does that mean that the whole system "wobbles" after the earth?
The change in the axis affects the position of both the stars and planets. And each planet's axis can change too.
The earth doesn't wobble but yes the entire solar system is actually precessing. Some of the stars are rising with us too. This is impossible in the standard model theory.
It was first introduced in the book Surya Siddhanta.. Which a lot don't know about.
A paper shows that the axial precession (or precession of the equinoxes) is since the entire Solar System disk is spinning (from 2021):

It is amazing. Thank you Thank you Thank you.
Dude I just found you and I love this !!!!
Holy crap you already liked it !!!!!!! Honestly gonna go binge your videos my brain thrirsts knowledge thank you !!!!!!
Nothing new--in AD 325 at the 1st Ecumenical Council of the Orthodox Church of the Roman Empire, the Spring Equinox fell on 25 March; during the discussions about the formula for calculating the date of Holy Pascha each year, the Holy Fathers agreed on "the first Sunday after the first full moon after the Spring Equinox" at which point the Pope of Alexandria pointed out that the sun had crossed the equator that year on 21 March, so that phrase was added to the kanon, and ever since that has been the date of the Spring Equinox. No doubt at some point in the future it will have to be revised once again.
There's also like Lilith which I'm sure they're using-a true north and a node North, which means Polaris is not actually true North star. If I'm not mistaken I think it may be Sirius or something like that I don't remember.
The wobble messes up our calendar if we don’t account for it. But it doesn’t cause tsunamis or anything! 😛
Which leads me to this question that hopefully will be your next video: what is the link between astrology and climate change?!
great video....love the plug at the end...subscribed without hesitation
Yeah that was pretty funny tbf
4.35 "...and Americans are celebrating Christmas in the middle of Summer". Yet the photo is of Cronulla, Sydney, Australia :)
I have a two questions.
The sun travels about 500,000 miles per hour (804,672 km) towards the star Vega. This was recently noted after astrophysicists discovered the shift in the light spectrum that occurs with distant galaxies. Like the Doppler effect that occurs with sound a similar thing happens with light. Thus astrophysicists are able to deduce the speed and rotation of distant galaxies, stars and the direction that they are moving, i.e., towards or away from us. The more the light shifts in certain wavelengths the faster the distant object is traveling. Thus they were able to deduce the speed of 500,000 mi/h that our sun is traveling through the Milky Way.
My question; is the sun's movement included in your presentation of the precession?
Because I believe this movement would explain why the constellations retrograde 1° every 72 years.
In 72 years the sun would have traveled 315,576,000,000 miles (507,870,342,144 km), about 1/18 the distance of a light year.
The Earth returning to the same position (tropical year) year after year while the axis remained stationary, wouldn't the distance the sun traveled in 72 sidereal years, from Earth's perspective, cause the constellations to appear to retrograde 1°?
It would be cool if you did a simulation from an outside perspective that included the Earth's orbit and rotation along with the sun's orbit and rotation against the background constellations over time.
I've read that the math to calculate procession is simpler if we consider our sun being part of a binary system. In that model, procession occurs due to the elliptical orbit of the sun around the barycenter of this larger system.
But would the distance the sun moved be enough to explain procession? If this were the case, wouldn't we be able to calculate the sun's orbit and determine the angles and direction necessary to calculate where the companion star is? Why wouldn't we have found this companion by now (even if it's a dim brown dwarf)?
But cool things to think about.
I agree with you. There needs to be another factor that is not addressed.
According to the Mayan Indians and their Codex, the solar system is bobbing up and down along the galactic ecliptic, z direction as it orbits the galaxy's core. The sun takes on a snake like motion as it travels through the galaxy. Hence the depiction of a snake when referring to the sun's motion. They mentioned the dark rift along the galactic ecliptic being the measuring stick, so to speak for their great Maya calendar and how the solar system moved long before astrophysicists discovered the sun was even moving.
So the extra variable to cause this precession of the equinoxes would be the bobbing motion in the z direction that occurs to the sun over time while it orbits the galaxy's center. the sun moves to the north and then moves back towards the south on 12,960/2 = 6,480 year intervals.
Besides, the star Vega is to the north, the constellations around the Earth are on a different plane than the direction the sun is moving. Thus why this z movement is causing the sidereal year to change while the tropical year remains the same.
great content brother!! It doesnt make any sense that this video has only 60k views.
Yes, we do. We love your video.
I’m just curious why people spend so much time measuring the apparent movement of the stars as it relates to the wobble of the earth. There must be some significance to the positions since apparently statues of the constellations were built. How long ago did the Sphinx look at itself on the spring equinox? Six constellation positions taking 2,160 years per constellation would indicate 12,960 years? What was happening at that time? Did they just want whoever followed to know when they were they? Who were they? Where did they go? What happened to them? Don’t tell me they were aliens. I think space travelers would have better ways to spend their time than building stone buildings.
that's very informative. thank you
I simply have to like this video, very informative and entertaining!
been trying to wrap my head around sidereal time and the visual helps. actually, it helped to clarify astrological concepts too: the vedic system of astrology (from India) is based on the constellations and uses sidereal time. however, western astrology (where pop culture horoscopes and what not come from) is based on the seasons and uses tropical time. the stars in the sky at the time of development were simply the label given. for example, aries is aligned with spring (forget about the aries constellation). aries is the fresh spark of spring energy that begins processes. So don't worry -- scorpios will still be those born in late october/november (dark, brooding, going into the underworld autumn) even when the sun is in scorpio the constellation in april :) the real mind fck with western astrology is the northern and southern hemispheres (opposite seasons)--so the energies are all wrong.
Astrologers should be creative and think new names for the signs to set them apart from Astronomy science.
@@FootLettuce if only astronomy and astrology had not been the same thing before...
Neither school of astrology makes sense.
wow, fabulous explanation
Good vid, but please point out how the 26 mile equatorial bulge is only one-thousandth the size of the Earth's circumference, so the Earth is just as spherical as a billiard ball.
It isn't as spherical as that. It does not spin like a homogeneous sphere would, and this is easily tested by measuring the moment of inertia. That measurement clearly indicates how the earth wobbles in its axis, because it doesn't spin like a homogeneous sphere would. It tells us that mass is distributed differently as varying locations on earth
You want a better example of what you think the earth is like? Look at jupiter
That kind of explained my question:
Is this means that along with precession, seasons are also slightly shifting possition around the sun? If so, then after some thousands of years we would see stars that now could be seen in winter, we will see them in summer? Im not sure if anyone would understand my question.
That's exactly right. The seasons will happen when the earth is at a different point along its orbit. So in 13,000 years, the earth will be on the opposite side of the Sun during summer. So stars that were visible in the winter will be visible in the summer in 13,000 years.
@@ItsJustAstronomical Thank you!
The seasons are not shifting. The model predicts it, but the historical evidence contradicts it. Which means it's wrong.
It was known about by civilizations before Hipparchus. Just imagine Göbekli Tepe from 11.500 years ago!!
Wiolant SunGazer did animals give themselves names 11,500 years ago ? Thought they were still busy picking fleas off each other
Go check out some of the Hopi prophecies.
@@cosmoanayiotos6924 11,500 years ago it was the end of the fourth Glacial Era and the end of the Paleolithic Period. Men were making very refined stone tools, they knew art (plenty of cave paintings and graffitis, bone and ivory figurines), they buried their dead with their belongings, they wore jewelry, they hunted very big preys (so they must have had a good social organisation)... not at all "animals", you little ignorant.
Perfect explanation! Thank you!
If you take the most precise wind up watch and set it to the exact time of you're cell phone, over time you lose time comparing the two. Could the last largest tsunami that we had slowed the Earth's rotation that much? Also, could the Earth's wabble be the actual reason for climate change more than anything else?
There are no wrong questions:
It would be interesting to calculate the precession values of all planets and our sun.
If there is. I don't know.
Maybe our whole solar system is sort off wobbling together.
I haven't found the values for all the planets, but Mars has a longer cycle of 175,000 Earth-years (en.wikipedia.org/wiki/Astronomy_on_Mars).
It is. Hence the Earth is not "wobbling" on its axis. The solar system is precessing.
I'm a Taurus too. Good Video.
Check out Hamlet's Mill and Graham Hancock. The precessional has been recorded and known for much, much longer than 2nd Century BC.
-Old Kingdom Egypt
-Maya
-Norse Mythology
Etc.
Good explanation.
It's a wrong explanation. There's no wobbling. I've been meaning to read Hamlet's Mill because I'm curious if the ancients did actually understand it better. Modern astrophysics is trash.
Wouldn’t the poles receive an equal amount of light every 13000 years resulting in the poles melting ?
The average amount of light would be about the same, but there's a positive feedback loop as discussed in my Ice Age video that complicates the matter.
Great post. Yes the earth is wobbling..What is causing it?...Planet X is a giant magnet...bigger than Earth which is a magnet as well. What happens when you move a huge magnet close to a smaller one...the smaller magnet moves and spins around .
Where is planet X? So far away it cannot be observed by telescope? So don't expect any measurable effect on earth by the magnetic field of such a distant body.
Plz update Christmas Date from 25th December 2023 to 15th January 2024
so if we have been using the Gregorian calendar or even a tropical method for keeping years that would mean our windows of signs has fallen out of line? Even since we adopted the Gregorian calendar we've moved 6 days behind the astrological frames.
Yes, that's correct. We've been falling out of line with the signs for quite some time.
Megalithic structures are lined up with certain stars.
If procession moves 1 degree every century then they know exactly how old the sphinx is.
Why do they lie about not knowing?
Excellent channel!
Another really interesting presentation. The general public is certainly very ignorant about all of this. I was somewhat as well!
Everything matters, has a purpose, has a meaning. I was thinking today about how the earth axis rotated every so 20,000 years and how it relates to zodiacs. Now 5 mins ago I was thinking wtf is a precession asked Siri bc of thinking thoughts and intuition and curious. Now I’m here watching this video about precession of the earth. Follow your intuition curiosity and intellect!!!
If the earth bulges why do we always see a perfect circle?
The bulge is small compared to the size of the earth. It's almost a perfect sphere. I greatly exaggerated the bulge in the video so you could see it.
It were the Vedic Sages who taught the world about The Precession of the Equinoxes
animation is quite good and understanding
I loved it! (Just like you said)
This is mentioned in surya siddhanta
I do like the video. Smart, fun. Thanx!
Ahh, tropical year, I forgot it was the tilt that governs the seasons, not the orbital position. Now precession makes sense in terms of the sun's position. (thank god, that was annoying me) So that means the equinoxes slide between perihelion and aphelion every 13000 years.
Is this wobbling affecting the climate? Or do you think it’s another cause?
It does affect the climate over very long periods of time. It's not causing much of any change over the past 100 years. This video explains more: th-cam.com/video/iA788usYNWA/w-d-xo.html
Thanks for this video, very informative. 👍👍👍
Are you sure? I've just watched a video explaining that this isn't true. Precession requires that one end of the axis is fixed, and that's not the case with the Earth.
this is best 3D Astrology part! thanks!
