I understood about 10% of the information. I need to watch it again with pauses and go searching some definitions to fully understand it. The fault is from my education, not from the video.
+celso nunes I agree with you ,my brain couldn't get around it, it would be great for someone explaining it ,but a great video and presentation I think
no need to understand at all. just look animations and you can see that earth's path around the sun is always changing which means that sun calender is wrong .
M. C Ka not necessary wrong. It is a reference that allows us to adapt time. Time is created by, which is not petfect. What can we compare it to make it "right?"
Though I don't understand most of what is explained, I am very happy that there is some one who will try hard to make it understandable. My sincere thanks to him.
After 11 years, I finally discovered this amazing video. The way to explain the science behind the universe reminded my primary school days. Informative Science books and videos like this makes me interested in science and the universe. I always appreciate the beauty of the nature and the universe. Thank you
This is so informative and I could learn to remember this with enough repetition, so I have it on loop. Thank you so much! Your relaxed way of speaking is so pleasant.
Nah, it's really advanced for high school students. They just need to know that earth revolves around the sun and earth rotates on its axis (titled at 23.4 degrees).
Great explanation. But those ellipses gives a wrong impression: the Earth's orbit is so little elliptical that we can't even distinguish its shape from a circle (its semimajor axis is 0.01% longer than its semiminor axis). The Sun is also much closer to the center of the Earth's orbit, being only 2% off.
@@aa6eheia156 you'd think this would be obvious but then there's kids watching and claiming things like earth being flat so I guess they should've made it clear
Well done, thank you. Celestial dynamics are mind-bendingly complicated. I can't imagine the math involved. I found your video searching for a similar video explaining the moon's orbital variations. Yours is excellent. Now I just need to watch it about five more times and think about each thing you say.
It's sooo satisfying and humbling though!! I wish I had an astronomy related career. For now I just watch these videos and try to explain it to my girlfriend. I explained precession to her and she came to her own realisation that seasons would be affected between the hemispheres over the 26000 year cycle. Her casual insight made me so happy.

Can it be that climate has always been variable, so that the current man-made "climate change" is a political myth? Especially given that it takes twenty-six thousand years for the to return to the same orbit around the Sun 3:19
This is one of the best video explanations I have come across. I strongly believe this video would be great to play for students in high school learning about this.
we recited in Holy Qur'an in which Allah said Sun, Earth and Moon all are moving in their orbits. But in school text books we read that sun is Steady and not moving... But now after some years when science get some more advancement so it also have known that Sun is also moving around it's orbit, which Allah has already told in Qur'an 1400 years ago... There are many more huge scientific achievements done with the light of Holy Qur'an,,, Subhan Allah 😍❤️🕋
They wouldn't dare. It talks about ice ages and massive climate changes being a natural cycle of the earth and shows that we've been in a global warming cycle for 11,000 years and will remain in one for 14,000 more (and there are other cycles overlapping this, as well). It doesn't fit very well with their endless fear mongering about all climate change being man made.
And you'll notice that Polaris never wavers from it position. All the constellations move around this, the North Star / Polaris. It's a fluke to think other wise. There is absolutely no way that Polaris could keep up with their theory and remain geographically in the exact same place after days, months, or years. It's a mathematical impossibility,. There are to many factors. And even if it were so, there would have to be intelligence involved of a higher power, not just happenstance from a supposed BIG BANG. The Big Bang is just as idiotic as thinking that Polaris can travel quad trillions of miles every minute, to keep in sync with a spinning flying earth.
Hum, learning is just not taking someone's word for absolute. Although in some aspects this does work to ones benefit. Science is continually changing the way it thinks. Here is a quote… "We'll know our disinformation program is complete when everything the American public believes is false" William Casey CIA Director 1981
I read all of this in a Time Life book about astronomy a long time ago as a child, and it's still difficult to fully comprehend as an adult. It's great to see it in video format though.
Science is not definite fact until 100% proven. That's what makes it science... many theories apply to why we have an elongated rotation around our sun. If you ask me, it's odd and we should be on a perfect rotation after thousands of years, unless another force applies a gravitational pull on our planet. The pull from Mars is too small and too far away and same goes for our other planets, the pull gets weaker the further you go. So why does our planet do that around our sun? It could be due to a binary star or black hole. A smaller binary star on the same type of orbit could be the answer. If a small star the size of Jupiter is floating around, it could cause our planet to be pulled towards it when it's nearest to the sun. This could also explain why we have such an elongated rotation. It could also explain winters getting colder and summers getting hotter. It could be getting near us again. Most stars are born with a binary or multiple and for us to have just one, is also odd..
Very informative. Brought much clarity on topic. So much of nuances in such a short video. Our Solar system is much more complex than we casually think. Thank you very much 🙏👍
All lies are complicated, that's why you don't get it. the truth is simple, most people hate simple because, they have been hypnotized by the TV. We've been raised to have drama and complications at every moment. When we, as engineers build machines, we don't complicate the machine we are building. that's for amateur's. Whoever created this realm ...NO amateur! Everything here is simple ...Except the peoples' phycology ...Which has been complicated, twisted and contaminated. We've been led away so far from simple, now we don't even believe the realm that was given to us is simple. so that, we could decipher it and create our own individual energies for survival and flourishment to live free of tyranny. Even our bodies are simple, we eat to make fertilizer then we should shit in the ground throw our seeds in there. We don't need anything else accept the simple earth to make a place home. We are simple self sufficient gardens that can terra form anywhere we go. simple, so you can stay alive. Every single person should have a course in engineering at an early age so, they understand how simple the very place they live is, instead of all this hocus pocus horseshit! it's really that simple! Nobody wants simple , they like to believe the TV magic show, that complicates EVERYTHING, period!
this is like a Religion, you have to believe it blindly. Why do you people believe in everything but God? Is it because God requires large amounts of discipline and a specific lifestyle you don’t want?
Fascinating - its paradox that we agree in the motion complexity and that any deviation is highly compensated for, yet somehow we can't say that a great designer was involved.
That reminds me of the time I was in Malin head in Donegal, Ireland in 1972, we saw a huge ball of light going from left to right (like the sun) moving across the sea on a beautiful clear sunny day, we were amazed as we never seen anything like that before or since, we were staying in moville on a fishing trawler training course. I am from Dundalk, Ireland.
I cannot help but be struck by the enormous contrast between the lucid, logical beauty of this extremely-well produced and informative video, and the predictably dull, simian contributions of the flat-earth brigade. What a diverse species we are - some aspire relentlessly to new heights and undiscovered horizons, while others choose to regress inexorably.
+Tomas O Maonaigh ....."others choose to regress inexorably".....I have determined that since the eyes contribute less than 50% of sight, most of the "others" completely lack dimensional or spatial awareness. They're using a slow "processor"

This was a very informative video. I'll have to watch it 2 or 3 more times before I can fully digest it. Just like food is for the body, knowledge is food for the mind. Thank you for taking the time to present this video.
What's even more amazing/why is that on earth winter takes place while the earth is the closest to the sun, and summer happens when the sun is the furthest away from the earth!!!
@@YoungBlood507 One does not get more heat by stepping further away from the heat source and colder by stepping closer to the heat source even if one tilts away from that source! cdn.ebaumsworld.com/mediaFiles/picture/2408945/85941518.jpg Think logic, not pseudo!
@@spyke123able this is space not earth, physics aren't the same, go search it up. The tilt of the axis is what gives our seasons. By your logic when earth is closer to earth its summer, but did you know if its summer for one hemisphere the other its winter.
BTW when this happens another great coincidence occurs... Earths polar star VEGA, at that time, is also pointing in the direction in which our Star (the sun) is traveling toward, with Sirius the brightest star in the night sky following us close behind in the same direction!
I suspected the Earth's motion relative to the Sun was more complex than it is generally alleged to be, but there is even more that is not covered in this video. The Moon exerts a pull on the Earth as it circles the Earth that makes the smooth ellipses shown in this video a lot "lumpier" than they shown to be even though the variations are relatively much smaller. If you add all of the perturbations together, the Earth is wobbling along an approximate path around the Sun as it wanders through the galaxy. It is all so amazing. Gravity rocks! I'm just amazed that we can calculate all of this information.
Gabriel Mendoza "I don't know what to do with this information..." You learn it, and along with learning lots of other things, you put them all together and learn how to think for yourself and not let other's think for you.
Astronomy has a deep fascination - on its surface it's easy to know the constellations, then with the planets interjected and the moon being fairly predictable - but the more we discover the more intricate it all becomes. Living by the ocean it seemed the tides were ostensibly easy to understand too, but they're more intricate than I initially understood - they're infinitely intricate affected by moon/sun and ocean floor topography, then add in large storm affects and there is constant shift. It's terrific that A. Navabi and the CassioPeia Project have illuminated some of these wild and lengthy cycles I knew nothing about. These graphics and the ambient music backdrop are so helpful to deeper understanding - THANK YOU !
6:22 eccentric orbit due to pull from other planets ex jupiter/saturn. 7:15 the axial tilt change every 41,000 directly related to ice ages, the next minimum tilt 11,800 AD.
It's amazing how complex the movement of celestial bodies in space are, there's so much more to it than meets the eye. I also find it fascinating how the sun is moving 150 miles per second around Sagittarius A, that is some serious speed.
@@athornbo7937 bro think about it... I'll give you a clue. Mass has NEVER been demonstrated to attract anything. The whole thing has massive holes in it, its not demonstratable. If they can't explain something they come up with some magical non property non demonstratable thing like dark matter
There’s especially one thing that really bugs me in this video. The ellipticity of earth’s orbit is massively exaggerated without telling the viewer this fact, as well as the precession of the orbit around the sun. The ellipticity of earth’s orbit only varies between the minimum of 0.000055, which means almost a perfect circle, to a maximum ellipticity of 0.0679, which is also almost a perfect circle to the eye. The difference is barely noticeable. It would have been helpful to inform the viewer that even such a small difference can have a significant effect on the amount of solar irradiation on earth. And the precession of the orbit around the sun takes 112,000 years for one revolution. That means that the orbit precesses by only 1° every 311 years. To get an idea about how slow that is: It takes 155 years to notice a shift as large as the diameter of the full moon in the sky.
@@jaweeit8728 I really don't understand how religion could possibly stay coherent with all these thousands of them, all claiming to be correct. How can you say specifically your religion is the only right one, and not the Christian God, or the Greek gods, flying spaghetti monster, or Ra/Atum?
Great video. I need to save the link to share with people this summer who didn't understand when I told them that the Big Dipper is only horizontal in summer and in winter, it's vertical, and if you look up at it and then orient yourself in a circle, you'll find a point when it looks like a giant question mark. *(Because its position in the sky is different, as the earth tilts, you can make it look horizontal in winter too, I just mean where it is in the sky is overhead, you can't make it look vertical in summer without tilting your head from our perspective, see this is why I couldn't explain this to them lol) They didn't understand the concept of the tilted axis the earth wobbles on, while it spins and rotates around the sun, and I couldn't explain it well enough on my own. This illustrates it perfectly. I wish I knew more about the night sky, I try to understand which planets are which, but I'm rarely places where it's dark enough to see every star. I think that tied our daily lives into the cosmos more. It's funny we're more "space age" now but 98% of us can't tell Venus from Sirius, or even name a star, or name Polaris as the North Star. 400 years ago everyone knew every planet and star in their chunk of the sky.
Just a reminder of how lucky we are to live on this planet! Look at how many things need to be where they are for a planet like earth to be habitable. Fascinating stuff.
You gotta love the way in which we've gained this knowledge its amazing. Nothing beats prediction from information and a clear openness about space, unlike some current (cough cough) understanding from certain individuals.
When people still farmed by the moon and foraged, fished and sailed by the tides, knew hundreds of plants, they had a better sense of time, context and scale. We flatter ourselves to think we're advanced. Ask whoever what phase is the moon or how long til the equinox, they'll think you're in a cult nowadays 😂
@@davidgough3512 Yea it seemed that a some of the knowledge we have today could have been more common knowledge back then, but as things became more specialized less people would have this awareness. I try to remember the location of the sun during the day and from my home I can tell the time roughly by its position, almost to the minute lol
Can it be that climate has always been variable, so that the current man-made "climate change" is a political myth? Especially given that it takes twenty-six thousand years for the to return to the same orbit around the Sun 3:19
Ancient Sumerians have writing on clay tablets with this understanding. Amazing. We’re coming full circle in the understanding of this. How did they know this in ancient times? A question worth investigation.
How did the Dogon tribe know about Sirius and it's moons ? Mauro Biglino was hired by the Vatican to re translate the old testament...and he came up with a story of 'space men". Makes you wonder why the Catholic Church owns most of the observatories in the world, and why a Jesuit priest came up with the big bang theory....and why they appointed a woman spokesperson to greet any Aliens that ' might ' pop up.
You explained very deeply and detailed. I would like to see this again and again. You make this video 12yrs before but still i can't see such type of detailed explanation of earths rotation.
Good and instructive video. Good graphics too. You could have also spoken about the stabilising effect that the moon has on the earth in its orbit, much like an acrobat in a circus carrying a long pole in his hands to balance himself or herself while walking on the rope.
Anyone ever considered that the ice ages and global warming are caused by the earth's relative position to the sun rather than human activity...? Edit: Made the comment before finishing the video and the ice age part was confirmed.
Obviously it was considered, but the current climate change is much, much more drastic than the natural climate changes of the past, and it exactly matches the amount of co2 we produce.
I tell everyone I know that global warming is just BS to scare people and make money. Earth has been going through changes long before humans showed up.
I tell you: NO ONE in the world has discovered the TRUE movement of the Moon, seen from the Sun! I discovered it 3 years ago, and I'm waiting for the opportunity to expose my solution to the whole world, in a filmed public conference (as well as other discoveries that will confuse many people) ..... This movement is not very complex, but know that it is NOT AT ALL helical type !! professor essef, in mathematics (active for over a year on TH-cam and Wikipedia, in astronomy & astrophysics). Paris, May 26, 2020.
@john underwood NO, it is not "a very good explanation of the celestial mechanics of the solar system. How could it be, when it starts with an animation/simulation showing something so different from Earth's real orbit?
Spectator Alius, it accurately dipicts the earth's movement. As has been observed many times. It IS a very GOOD explanation of the celestrial machanics of our solar system.
Solar system is moving all the time, sun is moving through the Milky way and other planets orbiting the Sun in spiral motion n all Solar system is orbiting around the galactic core in a spiral motion itself, and it takes 226 millions of years to orbit the galactic center (Milky way). This is not good example..
Imagine a geometric plane which passes through the center of the Sun and upon which the orbital path of the Earth lies (ignoring the galactic path). Call it plane EO. (Plane EO would, coincidently, pass through the center of the Earth.) Now imagine a plane perpendicular to EO which passes through the center of the Sun and the center of the Earth. Call this plane NS. Now imagine a line which is the rotational axis of the Earth. Call it line RA. And finally, imagine a line segment passing from the center of the Sun to the center of the Earth. Call this line ES. Lines RA and ES always intersect, but at a constantly changing angle. Each time this intersect is perpendicular is an equinox. Each time the intersection is maximally (or minimally) non-perpendicular is a solstice. The beginning and end of years can be arbitrarily defined by an angle of the intersection, RA ʌ ES. Any time the intersection, RA ʌ ES, forms the defined angle is said to be the beginning of the year. This definition of a year will always agree with the seasons.
You've said nothing to change what I posted. I simply gave a definition of a year which would remain consistent from the perspective of an Earth inhabitant throughout time. This definition of a year will always agree with the seasons, regardless of axial 'wobble.' The length of time of my described year would and must change constantly. Even a year defined to be a fixed, arbitrary length of time would change lengths due to relativity. Of all the many things that exist in our universe, concrete is not one of them. It is impossible to concretely define the length of a year, just as it is impossible to define simultineity.
PS - a 'sidereal' year assumes the stars don't move. It has been estimated that it takes 250 million years for our Sun to circle our Milkyway galaxy. If the Earth is actually 4.5 billion years old then we have gone completely around our galaxy at least 18 times (and survived). Now, there's a thought!
"We could define the length of the sidereal year to be based on a distant galaxy ...". Not a bad idea. On some time-scales none of these "years" are meaningful, but on the scale of the length of recorded human history, and being a human myself and a resident of our beloved planet Earth, I do like the more practical "tropical year." 26,000 years just seems like an awful long time. I'm not even sure if my great-grand kids will still be here then.
@1:50 When photographing the analemma, the tilt totally depends on the time of day, and from Australia it appears upside-down, the fat part of the 8 on top.
Excellent and brilliant , wonderful dialog, great graphics ….. should be required viewing in every high school in US( at least those who believe in science and don’t believe that the stars are just holes punched into the tin ceiling above our heads….great job, look forward to more of your videos.
I've noticed that Orion is out during the winter mostly. It was coming up around 3 - 4 am, now it's coming up about an hour earlier. Before you know it, it'll be coming up at 9 pm in a few months. I also just learned about the whole process of leap year, it's pretty wild. To have a leap year on the turn of a century only happens alevery 400 years, and the year 2000 had one, the last time before that was the year 1600 and the next will be 2400. Very interesting.
Great video! Some say that learning how the world works somehow "ruins the magic of it all" but if anything I find learning about the incredible complexity of our world only gives me a deeper appreciation and sense of wonder. If only there was a way to spread this love for knowledge.
I fully agree sir but that's smart questions out there and things need to be challenged and answered intelligently and fact is most see it on TV or read it somewhere hear it somewhere and adopt it as truth without any critical thought... why are we so content believing we have betters telling us how things work and what right and wrong are while completely sacrificing thinking in place of views that are unquestionable.. this seems like insanity to me... refusal to answer questions and have a conversation seem like juvenile beliefs rather than thought out opinions
Prove it to be a spinning ball. Watch the learning begin and you will find many people to share with . Find the curve and try and feel the movement. Two things you could never find. But that will only increase your need to learn .
Gary Ryan "try to feel the movement?" If you judge everything by your "feelings" you will only find the truth about your feelings, which have no bearing on reality. Anyways, that's how I feel about it.;)
That orbit you're showing is FAR more elliptical than any planetary orbit in the solar system. Earth's obliquity is like 0.1, it's almost perfectly circular. Therefore, it's precession is pretty small indeed.
+SirHuddleston Fuddleston Yes, I thought it was very exaggerated, that was not explained in the video, which is also why the temperature differences are much less significant than the video implies.
Fantastic video. I would add that on a more cosmic scale, most of this tiny relative motion becomes trivial as we are dragged by our sun around the Milkyway at half a million miles per hour. We are basically following an out-of-control fusion reactor to our eventual death as it expands, consumes us, and burns us alive.
I spotted this in the morning. I was a bit freaked out on why the stars were acting like that in the sky and now I know why. Thank you for this video! Much love and respect
Pretty good, but it contains one real blooper. The crossover point on the annalema ("Figure 8") is not the time of the equinox, currently. Currently the crossover will be on about 12th of April and 30th of August in 2014, not particularly close to the equinoxes. At equinox, the sun is just about midway between the solstices (not surprisingly), the top and bottom of the annalema. I still gave it a thumbs up.
I will just ask the flat earth people one question. Why is the flight time between Perth Australia and Johannesburg South Africa 11 hours 10 minutes. The flight time between Sydney Australia and Frankfurt, Germany 22 hours 30 minutes. The flight time between Sydney Australia and Santiago, Chile 12 hours 40 minutes. When on a flat earth map the distance between Sydney Australia and Frankfurt, Germany is the shortest. while the other two are much, much longer? All aircraft are similar and travel at similar speeds, you can check these flights if you like. It's a nice simple question with no math, science or trickery, so can you explain this?
dont be glad too fast. Can i ask the same question but a little differently: Why is the flight with a helicopter when only staying still in the air ENDLESSSS from point A to B ? I dont think you get this question....
Terence Ponting ..you dont need to fly in an airplane.. Just hover in a helicopter and you'll be in another country cause the earth is spinning at 1000mph. Right??.. If i travel from the east coast to the west coast flight time is around 3hrs 15 min.. How is flying west coast back to the east coast the same travel time when the earth is spinning
Charles McMillion Well, everything wasn’t figured out all at once, and we are still have many unknowns to this day. But we know that the ancient Greeks figured out the shape of the Earth, and also managed to get an extremely accurate measurement of its circumference considering the crudeness of the technology of its time. And Tycho Brahe, probably the best recorded naked eye observer, managed to create an amazingly accurate database of observations without a telescope. The data was good enough to provide Kepler with the data he needed to figure out that the orbits of the planets around the sun weren’t circular, but ellipses. We see as far as we do because we stand on the shoulders of the giants who came before us. I believe it was Einstein who said that.
Harmon Heat Sumerian tablets show the solar system and planets. INCLUDING PLUTO! Their maybe 5-10 thousand years old. However modern man didn't discover Pluto till around 1930. True

Earth's orbit isn't that elliptical as shown in the video. In fact it's almost circular the perigee is 149.8 million km and the apogee is 152.8 million km. So you can imagine the shape of earth's orbit

Sorry guys, but no civilizations knew about either elliptical orbits or precession prior to the post-Renaissance scientists - Brahe because he made the precise observations; Kepler because he did the math and showed elliptical orbits. Newton and his contemporaries were the first to show that this was due to an inverse-square force law. It would be impossible to demonstrate precession or nutation without more accurate and precise observations, which we didn't have as a human race until a couple hundred years ago. Sure, the heliocentric model was around 2000 years before Copernicus, but it's a big leap from heliocenric to ellipses and precession.
77GSlinger I apologize on behalf of science educators everywhere, because someone must have done a horrible job teaching you if (a) you have such a fundamental mistrust of the scientific method, and (b) you have such a fundamental misunderstanding of the underlying ideas. I will comment on just a couple things for clarification. First, Kepler developed a model based on observation; specifically, the observations of Tycho Brahe. Kepler did not know the cause of the elliptical orbits, he simply figured out that the motion was in fact elliptical. That all bound objects orbit in ellipses is incontrovertible, and backed up by mountains of evidence. I can't force you to believe it, but if you have the patience, you can watch e.g. one of the GPS satellites orbit the Earth, and if you make enough measurements you'll get an ellipse, sure enough. So, to clarify - you are wrong that Kepler's model was not based on evidence - quite the contrary, in fact. He used the evidence gathered by his former mentor, Brahe. If you arguing that the ellipse model only is true for a frame of reference in which the Earth is at rest - or, in the case of the planets' orbits, the Sun at rest - then I will happily agree with you. And that's one of the cool things about the animation we are commenting on - it shows the motion of the Sun around the galaxy. But this does not make the ellipse model garbage; just limited. And it certainly doesn't make a "vortex" model correct, and it doesn't remove the wrong aspects of the animation. If you're arguing that we still don't understand WHY they orbit the way they do, from a philosophical viewpoint or whatever, I will again happily agree with you. But most of the time, scientists have to accept the fact that they can't answer the WHY, and have to settle for the HOW. Second, I don't understand what your point was about Copernicus. I think it's kind of cool that his heliocentric model still wasn't correct, because it assumed circular orbits! The fact that his model was further refined by Kepler, Hooke, Newton, et al by including ellipses is a good testament to the steady development of better theories in science. Nowadays, a lot of physicists can't use Newtonian dynamics in their work, because they work in large/heavy regimes where Einstein's general relativity is a better model, or they work in light/small regimes where QCD is a better model. It doesn't make Newton's work garbage, just limited. For example, NASA used almost strictly Newtonian dynamics to get satellites to all of the nearby planets, and land rovers on Mars, etc. And, someday, I hope that we'll find a better model still that explains things that QCD and general relativity can't seem to do - even Einstein himself said he was certain this would eventually happen. So, to conclude, you can believe in spirals, vortices, etc. all you want, and you can believe that ancient civilizations somehow knew about complex scientific models despite not yet knowing the mathematics that went into them. I know better than to try to change your mind, but I can gently suggest that you look around you and behold the technological marvels wrought by what you believe to be lies and bullshit. I know that people such as you insist on having the last word, so I'll end here and give it to you. Take care.
Hay JEREMY: Are you showing off? or what? What are you trying to say? Did you expect the old civilization to know things that we know now with our satellites and telescopes?

Great explanation. But those ellipses gives a wrong impression: the Earth's orbit is so little elliptical that we can't even distinguish its shape from a circle (its semimajor axis is 0.01% longer than its semiminor axis). The Sun is also much closer to the center of the Earth's orbit, being only 2% off.

They wouldn't dare. It talks about ice ages and massive climate changes being a natural cycle of the earth and shows that we've been in a global warming cycle for 11,000 years and will remain in one for 14,000 more (and there are other cycles overlapping this, as well). It doesn't fit very well with their endless fear mongering about all climate change being man made.

Nice, I like the cut of your jib.
And you'll notice that Polaris never wavers from it position. All the constellations move around this, the North Star / Polaris. It's a fluke to think other wise. There is absolutely no way that Polaris could keep up with their theory and remain geographically in the exact same place after days, months, or years. It's a mathematical impossibility,. There are to many factors. And even if it were so, there would have to be intelligence involved of a higher power, not just happenstance from a supposed BIG BANG. The Big Bang is just as idiotic as thinking that Polaris can travel quad trillions of miles every minute, to keep in sync with a spinning flying earth.

Earth is flat. Stationnary
Shut up uneducated, try to LEARN for once
Education can be simple.
Apparently not simple enough for flerfers.
Science is not definite fact until 100% proven. That's what makes it science... many theories apply to why we have an elongated rotation around our sun. If you ask me, it's odd and we should be on a perfect rotation after thousands of years, unless another force applies a gravitational pull on our planet. The pull from Mars is too small and too far away and same goes for our other planets, the pull gets weaker the further you go. So why does our planet do that around our sun? It could be due to a binary star or black hole. A smaller binary star on the same type of orbit could be the answer. If a small star the size of Jupiter is floating around, it could cause our planet to be pulled towards it when it's nearest to the sun. This could also explain why we have such an elongated rotation. It could also explain winters getting colder and summers getting hotter. It could be getting near us again. Most stars are born with a binary or multiple and for us to have just one, is also odd..
Very. Astro priests made sure that it's not.

The Desiner of this complex and massive universe is truly worthy of Worship!
I suspected the Earth's motion relative to the Sun was more complex than it is generally alleged to be, but there is even more that is not covered in this video. The Moon exerts a pull on the Earth as it circles the Earth that makes the smooth ellipses shown in this video a lot "lumpier" than they shown to be even though the variations are relatively much smaller. If you add all of the perturbations together, the Earth is wobbling along an approximate path around the Sun as it wanders through the galaxy. It is all so amazing. Gravity rocks! I'm just amazed that we can calculate all of this information.
So if someone gets all upset about a fraction of a degree over a couple of decades, just have them watch this video.

Astronomy has a deep fascination - on its surface it's easy to know the constellations, then with the planets interjected and the moon being fairly predictable - but the more we discover the more intricate it all becomes. Living by the ocean it seemed the tides were ostensibly easy to understand too, but they're more intricate than I initially understood - they're infinitely intricate affected by moon/sun and ocean floor topography, then add in large storm affects and there is constant shift. It's terrific that A. Navabi and the CassioPeia Project have illuminated some of these wild and lengthy cycles I knew nothing about. These graphics and the ambient music backdrop are so helpful to deeper understanding - THANK YOU !

There’s especially one thing that really bugs me in this video. The ellipticity of earth’s orbit is massively exaggerated without telling the viewer this fact, as well as the precession of the orbit around the sun.
The ellipticity of earth’s orbit only varies between the minimum of 0.000055, which means almost a perfect circle, to a maximum ellipticity of 0.0679, which is also almost a perfect circle to the eye. The difference is barely noticeable. It would have been helpful to inform the viewer that even such a small difference can have a significant effect on the amount of solar irradiation on earth.
And the precession of the orbit around the sun takes 112,000 years for one revolution. That means that the orbit precesses by only 1° every 311 years. To get an idea about how slow that is: It takes 155 years to notice a shift as large as the diameter of the full moon in the sky.

They didn't understand the concept of the tilted axis the earth wobbles on, while it spins and rotates around the sun, and I couldn't explain it well enough on my own. This illustrates it perfectly.

Solar system is moving all the time, sun is moving through the Milky way and other planets orbiting the Sun in spiral motion n all Solar system is orbiting around the galactic core in a spiral motion itself, and it takes 226 millions of years to orbit the galactic center (Milky way). This is not good example..
Imagine a geometric plane which passes through the center of the Sun and upon which the orbital path of the Earth lies (ignoring the galactic path). Call it plane EO. (Plane EO would, coincidently, pass through the center of the Earth.) Now imagine a plane perpendicular to EO which passes through the center of the Sun and the center of the Earth. Call this plane NS. Now imagine a line which is the rotational axis of the Earth. Call it line RA. And finally, imagine a line segment passing from the center of the Sun to the center of the Earth. Call this line ES. Lines RA and ES always intersect, but at a constantly changing angle. Each time this intersect is perpendicular is an equinox. Each time the intersection is maximally (or minimally) non-perpendicular is a solstice. The beginning and end of years can be arbitrarily defined by an angle of the intersection, RA ʌ ES. Any time the intersection, RA ʌ ES, forms the defined angle is said to be the beginning of the year. This definition of a year will always agree with the seasons.
You've said nothing to change what I posted. I simply gave a definition of a year which would remain consistent from the perspective of an Earth inhabitant throughout time. This definition of a year will always agree with the seasons, regardless of axial 'wobble.' The length of time of my described year would and must change constantly. Even a year defined to be a fixed, arbitrary length of time would change lengths due to relativity.
Of all the many things that exist in our universe, concrete is not one of them. It is impossible to concretely define the length of a year, just as it is impossible to define simultineity.
PS - a 'sidereal' year assumes the stars don't move.
It has been estimated that it takes 250 million years for our Sun to circle our Milkyway galaxy. If the Earth is actually 4.5 billion years old then we have gone completely around our galaxy at least 18 times (and survived).
Now, there's a thought!
"We could define the length of the sidereal year to be based on a distant galaxy ...". Not a bad idea.
On some time-scales none of these "years" are meaningful, but on the scale of the length of recorded human history, and being a human myself and a resident of our beloved planet Earth, I do like the more practical "tropical year."
26,000 years just seems like an awful long time. I'm not even sure if my great-grand kids will still be here then.

@1:50 When photographing the analemma, the tilt totally depends on the time of day, and from Australia it appears upside-down, the fat part of the 8 on top.
Excellent and brilliant , wonderful dialog, great graphics ….. should be required viewing in every high school in US( at least those who believe in science and don’t believe that the stars are just holes punched into the tin ceiling above our heads….great job, look forward to more of your videos.
I've noticed that Orion is out during the winter mostly. It was coming up around 3 - 4 am, now it's coming up about an hour earlier. Before you know it, it'll be coming up at 9 pm in a few months. I also just learned about the whole process of leap year, it's pretty wild. To have a leap year on the turn of a century only happens alevery 400 years, and the year 2000 had one, the last time before that was the year 1600 and the next will be 2400. Very interesting.
what is a leap year?
@Mariah Fox oh thanks for the late answer :D
That is totally amazing. A person has to know all that before they can begin to understand global warming effects.
Amen
i love earth's rotation around the sun, it really makes my day!
Where's the proof?
Great video! Some say that learning how the world works somehow "ruins the magic of it all" but if anything I find learning about the incredible complexity of our world only gives me a deeper appreciation and sense of wonder. If only there was a way to spread this love for knowledge.
This comment is very good.
very well said
I fully agree sir but that's smart questions out there and things need to be challenged and answered intelligently and fact is most see it on TV or read it somewhere hear it somewhere and adopt it as truth without any critical thought... why are we so content believing we have betters telling us how things work and what right and wrong are while completely sacrificing thinking in place of views that are unquestionable.. this seems like insanity to me... refusal to answer questions and have a conversation seem like juvenile beliefs rather than thought out opinions
Prove it to be a spinning ball. Watch the learning begin and you will find many people to share with . Find the curve and try and feel the movement. Two things you could never find. But that will only increase your need to learn .
Gary Ryan "try to feel the movement?" If you judge everything by your "feelings" you will only find the truth about your feelings, which have no bearing on reality. Anyways, that's how I feel about it.;)
That orbit you're showing is FAR more elliptical than any planetary orbit in the solar system. Earth's obliquity is like 0.1, it's almost perfectly circular. Therefore, it's precession is pretty small indeed.
+SirHuddleston Fuddleston Yes, I thought it was very exaggerated, that was not explained in the video, which is also why the temperature differences are much less significant than the video implies.
Josh Kaufman Great video, though.
so true, bothered me too, but it's more a visual aspect to easily understand what he's trying to say
Well the precession is also highly exaggerated. Precession can be caused by perturbations from other planets
He would have to state that the graph is not to scale
Amazing video. The animations are very well done and make complex concepts much clearer. Awesome!
(Really don't get why so many thumbs down.)
Maybe they are all flat earthers...?
Maybe it's because of the poster's name?
music too loud at times !!!!!!
IQ !
Maybe the environmentalists who thinks CO2 is the only factor to climate change
Fantastic video. I would add that on a more cosmic scale, most of this tiny relative motion becomes trivial as we are dragged by our sun around the Milkyway at half a million miles per hour. We are basically following an out-of-control fusion reactor to our eventual death as it expands, consumes us, and burns us alive.
Damn
This video was uploaded 10-yeard ago
And way better than what is usually uploaded on TH-cam these days
They used to teach this in elementary school. Yes, really.
Why am I watching this after 10 years I should watched this when I was 5.... Then everyone called me genius...
Enjoy it much looking forward 2 more posts. Answered many of my questions
I knew most of the things in this excellent video. However, I have never seen them put together so well. Nicely done.
My mind just went kaboom!
Learned something new today.
You mean you believed this crap .Hahahaha Wow you people believe anything don't you . lmao .
WOW that just blew my mind. I've always been fascinated by this stuff thanks for making it relatable and understandable. Keep up the great work.
Understandable?? Are you sure?
I spotted this in the morning. I was a bit freaked out on why the stars were acting like that in the sky and now I know why. Thank you for this video! Much love and respect
Pretty good, but it contains one real blooper. The crossover point on the annalema ("Figure 8") is not the time of the equinox, currently. Currently the crossover will be on about 12th of April and 30th of August in 2014, not particularly close to the equinoxes. At equinox, the sun is just about midway between the solstices (not surprisingly), the top and bottom of the annalema. I still gave it a thumbs up.
I will just ask the flat earth people one question.
Why is the flight time between Perth Australia and Johannesburg South Africa 11 hours 10 minutes.
The flight time between Sydney Australia and Frankfurt, Germany 22 hours 30 minutes.
The flight time between Sydney Australia and Santiago, Chile 12 hours 40 minutes.
When on a flat earth map the distance between Sydney Australia and Frankfurt, Germany is the shortest. while the other two are much, much longer?
All aircraft are similar and travel at similar speeds, you can check these flights if you like.
It's a nice simple question with no math, science or trickery, so can you explain this?
In the 'flat earth model' airplanes can't fly, so your argument is totally useless.
loooool
didn't see this one coming
dont be glad too fast. Can i ask the same question but a little differently:
Why is the flight with a helicopter when only staying still in the air ENDLESSSS from point A to B ?
I dont think you get this question....
Terence Ponting ..you dont need to fly in an airplane..
Just hover in a helicopter and you'll be in another country cause the earth is spinning at 1000mph. Right??..
If i travel from the east coast to the west coast flight time is around 3hrs 15 min..
How is flying west coast back to the east coast the same travel time when the earth is spinning
🌎
I dont know about you guys, but I look at my calendar, it's pretty accurate.
I like you
1:24 gotta love how the stars pass in front of the clouds which are the same each day
Even though I didn't get anything from this video, I enjoyed watching it.
Haha me too
Omg. I'm not alone. 😅

And just think...people knew a lot of stuff like this a loooong time ago, before telescopes were invented
Not really. They figured it out after Galeleo pointed his telescope up.
Charles, you clearly lack in history then. Ancient civilisations know all about this when they been living in caves.
@@broforce4485 Cite your scholarly sources, "Bro".
Charles McMillion Well, everything wasn’t figured out all at once, and we are still have many unknowns to this day. But we know that the ancient Greeks figured out the shape of the Earth, and also managed to get an extremely accurate measurement of its circumference considering the crudeness of the technology of its time.
And Tycho Brahe, probably the best recorded naked eye observer, managed to create an amazingly accurate database of observations without a telescope. The data was good enough to provide Kepler with the data he needed to figure out that the orbits of the planets around the sun weren’t circular, but ellipses.
We see as far as we do because we stand on the shoulders of the giants who came before us. I believe it was Einstein who said that.
Harmon Heat Sumerian tablets show the solar system and planets. INCLUDING PLUTO! Their maybe 5-10 thousand years old. However modern man didn't discover Pluto till around 1930. True
Every space video I see so special never get I enough to take in. Even watch it sometimes and listen to music I like imagine me travel the space. New rock and legend rock like deltaparole, foo fighter, nirvana, rush.
Try Hawkwinds ' in search of space '... very trippy !
Still don't understand how we are moving so fast in space and yet never see different stars or distant ones getting brighter as we move past them. Any help!?
Earth's orbit isn't that elliptical as shown in the video. In fact it's almost circular the perigee is 149.8 million km and the apogee is 152.8 million km. So you can imagine the shape of earth's orbit
True
..Así es como desinforman algunos videos...
@@MauroMan_ sir I can't understand what you have commented. If possible type in English
@@rohitthanvi2479 .. I say, that´s how they give us misinformation videos..
Rohit Thanvi you must use the traductor!! There are many languages on the world, not only English, than 572 million Spanish speakers in the world (7.8% of the world’s population)
I had no clue. I seriously thought the planets went around the sun simply in a circle. Wow... Much more complicated
The circle is extremely exaggerated in this video. From first glance it looks almost completely circular.
It's going to look circular to an eye; however, it's not. Earth's aphelion is 152,098,232 km while it's perihelion is 147,098,290 km.
They forgot to mention the sun is moving too, As well as our local gallaxy.
Fa Vang No .. Only the universe is moving .Not the earth. It is stationary. No spinning , No rotating.
Gary Ryan Are you saying the sun is moving around the earth? lol u a flat earther?
No . This has been proven many times. But it's just now being let out . The science community can not hold it back any longer. There theories don't .. cant hold water any more. and they know it. Scientific theories are not fact as they have led you to believe. Science is finally going to have to stop all there lies. Search ..Earth Is Center Of Whole Universe
Gary Ryan go take your meds and leave us serious thinkers alone.
ofosusam OK Genius . So you reject science now ? . Go play with your toy globe. Spin it really fast . Then try and put one of your toy army men oh it. See if it sticks. Your clueless
The earth rotates east, making the Sun looks like it's coming up in the east each morning.
Sorry guys, but no civilizations knew about either elliptical orbits or precession prior to the post-Renaissance scientists - Brahe because he made the precise observations; Kepler because he did the math and showed elliptical orbits. Newton and his contemporaries were the first to show that this was due to an inverse-square force law. It would be impossible to demonstrate precession or nutation without more accurate and precise observations, which we didn't have as a human race until a couple hundred years ago. Sure, the heliocentric model was around 2000 years before Copernicus, but it's a big leap from heliocenric to ellipses and precession.
No pre-renaissance civilizations knew about orbital procession? Ya and Columbus discovered America, right?
Sorry, I was not very clear. I was referring to the precession of planet orbits. Anybody with a spinning toy top can see precession :)
77GSlinger I apologize on behalf of science educators everywhere, because someone must have done a horrible job teaching you if (a) you have such a fundamental mistrust of the scientific method, and (b) you have such a fundamental misunderstanding of the underlying ideas.
I will comment on just a couple things for clarification. First, Kepler developed a model based on observation; specifically, the observations of Tycho Brahe. Kepler did not know the cause of the elliptical orbits, he simply figured out that the motion was in fact elliptical. That all bound objects orbit in ellipses is incontrovertible, and backed up by mountains of evidence. I can't force you to believe it, but if you have the patience, you can watch e.g. one of the GPS satellites orbit the Earth, and if you make enough measurements you'll get an ellipse, sure enough.
So, to clarify - you are wrong that Kepler's model was not based on evidence - quite the contrary, in fact. He used the evidence gathered by his former mentor, Brahe.
If you arguing that the ellipse model only is true for a frame of reference in which the Earth is at rest - or, in the case of the planets' orbits, the Sun at rest - then I will happily agree with you. And that's one of the cool things about the animation we are commenting on - it shows the motion of the Sun around the galaxy. But this does not make the ellipse model garbage; just limited. And it certainly doesn't make a "vortex" model correct, and it doesn't remove the wrong aspects of the animation.
If you're arguing that we still don't understand WHY they orbit the way they do, from a philosophical viewpoint or whatever, I will again happily agree with you. But most of the time, scientists have to accept the fact that they can't answer the WHY, and have to settle for the HOW.
Second, I don't understand what your point was about Copernicus. I think it's kind of cool that his heliocentric model still wasn't correct, because it assumed circular orbits! The fact that his model was further refined by Kepler, Hooke, Newton, et al by including ellipses is a good testament to the steady development of better theories in science.
Nowadays, a lot of physicists can't use Newtonian dynamics in their work, because they work in large/heavy regimes where Einstein's general relativity is a better model, or they work in light/small regimes where QCD is a better model. It doesn't make Newton's work garbage, just limited. For example, NASA used almost strictly Newtonian dynamics to get satellites to all of the nearby planets, and land rovers on Mars, etc.
And, someday, I hope that we'll find a better model still that explains things that QCD and general relativity can't seem to do - even Einstein himself said he was certain this would eventually happen.
So, to conclude, you can believe in spirals, vortices, etc. all you want, and you can believe that ancient civilizations somehow knew about complex scientific models despite not yet knowing the mathematics that went into them. I know better than to try to change your mind, but I can gently suggest that you look around you and behold the technological marvels wrought by what you believe to be lies and bullshit.
I know that people such as you insist on having the last word, so I'll end here and give it to you. Take care.
77GSlinger lol wtf?!
Hay JEREMY: Are you showing off? or what?
What are you trying to say? Did you expect the old civilization to know things that we know now with our satellites and telescopes?
