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.
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?"
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.
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.
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
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 🙏👍
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.
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).
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
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.
Scary! I feel like an ant sitting on a rock that suddenly began rolling downhill. I didn’t realize how erratic our (the earth’s) motion is. This video makes me appreciate the enormity of our solar system, the Milky Way galaxy and eventually our universe. I love the way you have explained everything. Even then I have pause and think and visualize things in my head. Thank you.
@@anti-christ.666 like our junk DNA? That was you know just useless and left over from prior evolution... Or our appendix... Maybe you just don't understand things because you look at them as chaos instead of strategic. A tree doesn't have a brain, so why does it drop it's leaves in the fall? Those leaves protect the ground and rejuvenate the soil, we are the idiots that remove them. Nature is not chaotic we are just ignorant and self absorbed.

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.
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 !
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.
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.
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 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"
OhevTorathMoshe- So true, but now you are just showing off. I have a growing fear, Asimov's Foundation series is coming true: At least from what is in the first book.
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 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.
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
@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.
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?
"If someone tells you how many years old they are, you might ask them: "Is that sidereal, tropical, or anomalous years?"" And they might quickly look for someone else to talk to.
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!
I don’t know if you ever considered that Earth is basically a space ship. We travel around the cosmo following the Sun, we are never in the same place in the deep space twice. In fact we move, meaning this year we are not in the same place where we were last year and so on. Mind blowing if you ask me.
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.
@@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?
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.
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..
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.
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.
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.
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 RU-vid and Wikipedia, in astronomy & astrophysics). Paris, May 26, 2020.
Yet again orbital motions of the planets totally ignore the fact the sun is moving at 250 km/s or 150 miles/s in its orbit. The actual paths of the planets and moons are long slightly wavy lines that appear to us as orbits. There are so many forces and effects that perfect circles or perfect eclipses would be considered as freak occurrences. And no, the moon does not orbit the earth, it orbits the sun and travels a slightly more wavy path than does earth, so it appears to us to orbit the earth.
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!
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
Every time I learn about astronomical facts I can’t help being amazed at the enormous amount of hours our ancestors spent looking at the stars in order to start making sense of it all. Just the fact that centuries ago, with none of the technology we take for granted, people could calculate the days of eclipses and where on earth they could be watched from is a testament to human resourcefulness and thirst for knowledge.
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.
@@whoeverman8297 I suppose you have a PhD on astrophysics and have spent your whole life researching the phenomenon whilst collaborating and writing papers with other scholars?

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.
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

This was beautiful beyond measure! I knew 90% of the "facts" about Earth motion (but not everything) thanks so much for refreshing. This recap video was beautiful 😍in its own right.
Wow. Mind-blowing. The power of computer graphics. I learned more in seven minutes than in high school. The Earth is literally wobbling and spinning and rotating and orbiting all at the same time. and most people think it's spinning and orbiting in a perfect circle around the Sun. So informative and comprehensive and interesting and fascinating and fun to watch
Abhishek Tripathi I think they just know fake CGI cartoon nonsense when they see it. Earth moves indeed, pull the other one. Doesn't matter how many you share a delusion with, you don't get points for getting it wrong.

If you hang a bag of sand with a small opening below and give it a circular momentum, it will draw exactly the same pattern as Earth movement around the sun.
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

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.
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!?
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.
0:06 I think it's Mercury Or venus( don't know exactly which come first 😅) which is orbiting Sun! Because it's changing its elliptical path in circular manner
