70s - 2000s - People so smart and able to work out the mathematics of orbital rotations. Working out the exact mathematics to send space crafts to distant planets. 2017 - The Earth is flat
Aristarchus Greek philosopher of Samos (310-230 BC) advanced the heliocentric model as an alternative hypothesis to geocentrism but the original text has been lost. A reference in Archimedes' book The Sand Reckoner (Archimedis Syracusani Arenarius & Dimensio Circuli) describes a work by Aristarchus in which he advanced the heliocentric model.

@@petermarshall7352 Hi. I am inter in space sciences, but couldn't find anywhere to study orbital mechanics from. Can you please suggest a source which includes the maths you mentioned in your post?
Great video and very well explained. Still, I miss the geometric and mathematical description of the coverage zones in a similiar manner to the one done for the orbits, which is very good.
Convection 369 how the cycles continue, like poles shifting, like earth moving up or down. Like the Coriolis effect and exothermic and Endothermic convection. The fact that the momentums of polarity, eventually changed and continue in motion completing convection cycle. This zero point field or free energy basically like free falling towards the earth. If such a motion of speed happened with a embodiment. It would cause the embodiment to circle the earth in a stable orbit. As such all stable orbits like the earth around the sun or the sun around the galaxy. This spiraling notion of constant free energy movement dynamics, negative and positive inertia or forces which sustain the system.🔄☯️⚕☁️➿♾ Interesting intriguing, the stable orbit or free energy interval. Not to little to be left or to much to fly off just enough to keep circulating.

Wow, some really smart people are working with this knowledge to accomplish great things in space. It's amazing that people figured this out with mathematics and physics. Very impressive .
Definately not. This stuff is amazing. I barely understand it so I have a lot of respect for the people who figured it out and used it to travel through space.
That’s intentional. They don’t want you to be able to make sense of it. They want you to just “trust the experts/science” instead of using your own common sense and seeking the truth for yourself. It’s all a lie.
Bullshit. Learn a bit about electricity and magnetism and you'll learn something about what holds things together. Learn a bit more and you'll find that DARK ENERGY IS NOT GRAVITY!!
@@manifold1476 You are correct. Dark energy is certainly not gravity. In fact, it acts more like anti-gravity. Gravity accelerates masses toward each other, whereas dark energy accelerates masses like galaxies away from each other. It will be very interesting when science is able to tell us what gravity, dark matter and dark energy really are and how they work.
Thank you for the educational video. I have a question: Why when we place a Satellite into earth orbit (does not matter what orbit) The Satellite will eventually falls back into earth. Even if you place the Satellite in GEO Synchronous orbit, it will take million years but at end it will falls back into the earth. Then why planets don't fall into their Suns that they have been around it for billions and billions of years? Thank you in advance.
Ben Nosrati great question my friend. An object in motion tends to stay at motion. I’m not sure how much a satellite weighs but a planet could weigh billions and billions of pounds, there fore having more kinetic energy to continue orbiting than a satellite. Also our sun probably has way stronger orbital energy than our planet. (9 planets orbit the sun, earth only has the moon)
Planets are INSANELY massive, the Earth having a mass of 5.972×10^24 kg, so the force of drag due to solar wind or other planets would be extremely small and would take quite a while. There are also tidal forces from other planets and the Sun that will disturb Earths orbit but will also keep it in its currect orbit. The disturbances are currently very stable but in some billions of years Mercury will be ejected from the system and the perturbations will become more amplified and extreme as they were in the solar systems early days, many planetesimals being flung into high orbits and getting sucked into other planets or being shredded by tidal forces from Jupiter (think of the asteroid belt, which could have formed a planet but Jupiter's mass caused tidal forces to keep the bits from coagulating too much and actually formng a planet, but instead the dwarf planet Ceres). If anyone has any questions or this didn't make sense please let me know because I would love to try to help people understand this because I absolutely love astrophysics and I aim to earn a PhD in the field and there is nothing I love more than talking about space!!!
+ Ben Nosrati: It's a matter of the numbers. Orbital decay in low and medium Earth orbits, depends on atmospheric density at the minimum altitude of the satellite. For simplicity's sake, let's restrict this to circular orbits. Atmospheric density drops exponentially with altitude, h, and the altitude difference to get half the density is something like 18,000 ft ≈ 5.5 km ≈ 3.4 miles. At h = 100 miles, I think the time to Earth-fall is measured in months. At h = 200 miles, atmospheric drag is so very much lower than at 100 mi, that other forces that were much tinier at 100 mi, start to become important. By the time you get to geosynchronous altitude, there's virtually no atmospheric drag, and it's a matter of gravitation from other Solar System bodies, and the Earth's magnetic field acting on any magnetic dipole moment the satellite might have, perturbing the orbit. I don't know what the expected life of a geosynchronous satellite is, absent any thrusts, but it's probably as you say, millions of years; maybe much longer. With the planets, which have had 4+ billion years to work on each other's orbits, the ones we are left with, are in orbits that are stable virtually forever. Current theory has a prediction horizon of somewhere in the realm of 100,000,000 years, beyond which prediction is impossible due to chaos theory. Interplanetary space, and the gas and solar wind particles in it, is so extremely sparse that it will have no effect on planetary orbits from now until the Sun blows off its outer layers, several billion years from now. Fred
Ben, the difference is drag. Things we put into Earth orbit are not technically completely out of the atmosphere. There is still a tiny bit of drag where they orbit, and this causes orbits to decay over time. It's a slow process, but nowhere near as slow as you are talking about (millions of years). Moons orbiting planets and planets orbiting the sun are in a virtual vacuum, so there is no drag on them - and as others have pointed out, they are WAY more massive than a satellite, so any tiny amount of drag just doesn't accelerate them like it would a satellite.
I did wonder, with the moon despite being so far away has such a significant pull on our oceans and seas, how much does its gravity affect the satellites? The video describes it as orbital perturbations, but most satellites can actually re-align themselves without thrust/fuel?
It's important to understand WHY the moon's gravity effects the oceans. It's not necessarily the strength of the gravity that does it. It is the size of the Earth that creates the issue. The force of gravity gets weaker the farther you get from the source. For something the size of the Earth, that means the force of gravity is considerably stronger on the side of the Earth which faces the moon than the side opposite the moon. This VARIANCE in gravity is what causes tides. The moon pulls the waters because the force on the water (which is at the surface of the Earth) harder than the rest of the Earth. With something the size of a satellite, the force from the moon is the same on every part of that satellite so these tidal forces do not exist. There is however some variance in the force depending on where it is in orbit, but these variances are very small. They have a negligible effect, but technically SOME effect. Even Jupiter has a small effect. It is difficult to say exact what effect these things have because there are many factors involved, and probably the most significant is simply orbital decay due to the space in low Earth orbit not being a perfect vacuum, so any effects from the moon or Jupiter are dwarfed by the effects of drag - which in itself is very tiny. Even so, satellites do need periodic boosts to push them back into their desired orbits. There is no need to distinguish what factors caused what. They just look at the parameters as they are, and adjust them to what they need to be without much regard to what all factors went into causing the change in orbit. The vast majority of it is still just drag.
"There is no need to distinguish what factors caused what. They just look at the parameters as they are, and adjust them to what they need to be without much regard to what all factors went into causing the change in orbit." True, spacecraft controllers don't much care what caused the drift; they just need to concentrate on getting the 'bird' back where it should be. But celestial mehanicians *do* care. And if I might amplify a bit, your explanation of tides; yes, tide (tidal gravitational force) is due to variations of gravitational force with position. [In mathematical technicality, it's the spatial gradient of the vector force of gravity; which makes it a tensor of rank 2.] And in the case of the Moon acting on Earth, it is not only stronger on the near end of Earth than the far end, it's also different in direction from side to side. The result is a stretching of our planet along the Earth-Moon line, together with a uniform compression in the plane perpendicular to that line, which is exactly half the magnitude of the stretching effect. So the overall distortion is actually volume-preserving. [The tensor is trace-free.] Also, if you calculate how much the tide should rise and fall due solely to tidal gravity of Moon (and Sun!), it comes out to a few cm. The several meters we actually see, and the huge variation in tidal amplitudes and times from one place on Earth to another (see Bay of Fundy) are due to the mobility of water vs the relative immobility of the sea floor. (The "solid" Earth does also distort due to tidal forces, but it doesn't flow hundreds to thousands of miles.) Absence of this explanation has been pointed out as a failing of even most physics teachers. Fred
Dido... until I learned some simple tips - now It's super easy & kinda boring now, to the point of the Docking assist tool now just gets in the way. Heres the Sequence... Steps 2-4 is the key to all of it. 1. Start at a 100m distance and zero out reletive speed between ships. 2. On both ships - Set docking ports as targets!!! 3. On both ships - Set MechJeb/SAS to always point ship at their targets (docking port always point at each other)!!! 4. USE your Nav Ball - Understand how your RCS thrusting moves your Prograde indicator so it lines up with target indicator (note: relying on the "magic following camera drone" aka external "cheat" view actually makes docking very difficult - using 2D perception to fine tune 3D movement & distance) 5. Now use RCS thruster to start a slow & steady (1-4 m/s) forward movement toward target. 6. As you close in, keep making RCS thrust adjustments to keep prograde & target indicator lined up. 8. Keep your eyes on the Nav Ball and target approach speed indicator. 9. Within 10m slow to under 0.5m/s ... and small RCS adjustments... and at 5m turn off SAS... and .... poof - you've docked.
And we spin in a spiral galaxy so the corkscrew reality as we follow the sun..... evolved reality needs to be taught so people can understand what exactly life is
The helical spiral that the planets follow while orbiting the sun does not affect the orbits of satellites around the earth enough to affect this discussion of orbital mechanics. That topic is more advanced and would needlessly complicate the discussion since it has a very small effect on earth-satellite orbits.

Vacuum effortless any effect while gravity is everything around the satellites and planets. I believe that there'd take into consideration since masses are also into movement so vacuum should work together within awhile distant universe.

Witchcraft!! Demon speak! (Forming hex signs and covering my eyes...) Honestly, I think of the folks that compute orbital values, and those calculating intercept calculations for long distance flight, as unadulterated geniuses. Seriously, this is WAY above my comprehension. Good job people! (just sitting here stirring dirt in my clay pot).
And before that earth was known to be flat sense humans been on earth. In the 2nd and 3 rd century scientists and astronomers took what the Greeks told them about earth and changed it to heliocentric globe earth which is a model not a real example of earth.
Pariah Sojourner Prophet Muhammad seemed to have thought that the sun went somewhere when it set, and that somewhere was below the throne of Allah. Yet in reality the sun is actually not setting, but rather the Earth is rotating in a certain way so that it seems to be setting. So at that time in Arabia it was believed the earth was flat.

I have always wondered if it was possible for a lunar orbiter to "slam" into the moon by simply staying in one place along the moon's path around the Earth until the moon completed an orbit?
@Kit Canyon ok, that part I get. Perhaps I should have worded it better. But let's say it is a shuttle or a rocket instead of an orbiter. The rocket stays in one place directly along the moon's orbit until the moon comes back around. At that point, would the rocket then "slam" into the moon even though it was stationary the whole time?
What decides how close a planet orbits to the sun? For example sometimes you see a planet like Jupiter close to the sun and sometimes you see a planet like Jupiter orbit far away depending on the star system? How does that happen?

you can, its just that launching from equator due east is going to use more inertia of earths rotation to get into orbit easier. so its more efficient launching from equator. if you dont want to orbit specific latitude
I don't get it. Why do flat Earthers even click on this video??? I KNOW baseball is real. I just find it stupid, so I don't watch it. flat Earthers kinda "know" that this is NOT real + they find this whole thing stupid and yet, they watch these videos
I think 80% of these guys are trolls. The other 20% may have a need for opposing something. Lots of people get energy from actively opposing something. That is actually a strength, in my view; however, using one's strengths just to get people mad just adds to nothing.
can something just sit still at a distance from a mass? basically can a moon just sit still in a gravity field from a planet? why does it always circle the planet and can’t it sometimes just sit still at a fixed distance away without circling it?
Gravity attracts evething not matter how far away so if the obkect sits with 0 relative velocity to another object they will ventually crash because of that. So they need to move to not crash
People tend to think that when things are "in space" they are "weightless", this is not a fact. For instance if you are at the altitude of the ISS you weigh 88% of what you do on earth at sea level. The ISS stays on orbit because it is also moving laterally at about 17000 mph so as it falls toward earth it also misses hitting the earth and simply orbits the earth. If you went straight up to 240 miles high, and stopped, you would start falling and hit the earth again , moving at thousands of miles per hour

Nice. Science explained via Tomahawk cruise missile clips and animations of a giant firing a rifle. Way to go! Hu Ra let's Kill Kill Kill as there's no better way to explain physics.... :(
how planet rotate the sun? what is the reason of rotation? is planet axis is motor or orbit is track where planet most go on this imaginary circle line? and why sun does not rotate? honestly i dont know anything?
1. planets orbit other objects because they move sideways as the object pulls on them, cancelling out the sideways momentum but now the downwards pull is sideways itself. rinse and repeat. 2. no reason, not everything has reason to it, they have causes but not reasons. 3. trajectories are not constant, they change all the time. 4. it does, you can track this using sunspots.
There is no consensus on why Venus spins the opposite way. The most common hypothesis is that it doesn't spin the opposite way; there was just a collision of some sort that knocked Venus upside down. Other hypotheses include tidal forces from the sun. Yes, our moon spins, but since it is tidally locked with Earth, the rotational period is equal to its orbital period (which is the case for most moons in the solar system).
@@willoughbykrenzteinburg thanks for that , venus getting flipped over makes sense but i still think the moon doesnt spin, if it did there would be no dark side , different countries on the earth would see a different view of the moon , surely?
@@NOT_SURE.. the moon most certainly spins. We see the same side because for every degree of rotates, it has traveled around in orbit that same amount. If you were on the moon, the sun and stars would rise and set just like on Earth. Just everyy 27.3 days or so. It is rotating for certain. The moon doesnt have a dark side. The side of the moon we never see gets just as much light as the side facing us.

Well this made sense more than flatspacers and flatearthers believe, but still limited on their understandings of Gravity and Magnetism. I don't think human's have the capacity to comprehend the idea there could be an Implosion field near the center of their planet causing acceleration with lagforce that causes weight when not in the state of Free Fall. It is nessisary to have this attracting implosion field to pull on moon's and planet's with an outwards force also from their circular motions in order to have an elliptical orbit path. So the differential between orbit and rotation would cause the "g"constant:(Orbit÷(Rotation×2))= "g". And so: (Orbit÷(Rotation×g))=d. The rate the sun's pull is diverted to the center of earth to pull on it's surface of the planet as an implosion field with acceleration who's lagforce causes weight.
Does any flat earth person can explain to me why all those mathematics calculation work perfectly in a round planet? Do you have same explaination for a flat earth?

Even so, satellites do need periodic boosts to push them back into their desired orbits. There is no need to distinguish what factors caused what. They just look at the parameters as they are, and adjust them to what they need to be without much regard to what all factors went into causing the change in orbit. The vast majority of it is still just drag.
"There is no need to distinguish what factors caused what. They just look at the parameters as they are, and adjust them to what they need to be without much regard to what all factors went into causing the change in orbit."
True, spacecraft controllers don't much care what caused the drift; they just need to concentrate on getting the 'bird' back where it should be.
But celestial mehanicians *do* care.
And if I might amplify a bit, your explanation of tides; yes, tide (tidal gravitational force) is due to variations of gravitational force with position.
[In mathematical technicality, it's the spatial gradient of the vector force of gravity; which makes it a tensor of rank 2.]
And in the case of the Moon acting on Earth, it is not only stronger on the near end of Earth than the far end, it's also different in direction from side to side.
The result is a stretching of our planet along the Earth-Moon line, together with a uniform compression in the plane perpendicular to that line, which is exactly half the magnitude of the stretching effect. So the overall distortion is actually volume-preserving. [The tensor is trace-free.]
Also, if you calculate how much the tide should rise and fall due solely to tidal gravity of Moon (and Sun!), it comes out to a few cm. The several meters we actually see, and the huge variation in tidal amplitudes and times from one place on Earth to another (see Bay of Fundy) are due to the mobility of water vs the relative immobility of the sea floor.
(The "solid" Earth does also distort due to tidal forces, but it doesn't flow hundreds to thousands of miles.)
Absence of this explanation has been pointed out as a failing of even most physics teachers.

I learnt so much from this.
ok, I feel ready to play kerbel sapce progrma
KSP is a pain in the butt trying to rendezvous without cheating... lol
gets easier after 1000 hours :)
or factorio
Rendezvous isn't that hard... docking without a docking assist tool.. now that's torture...
Dido... until I learned some simple tips - now It's super easy & kinda boring now, to the point of the Docking assist tool now just gets in the way.
Heres the Sequence...
Steps 2-4 is the key to all of it.
1. Start at a 100m distance and zero out reletive speed between ships.
2. On both ships - Set docking ports as targets!!!
3. On both ships - Set MechJeb/SAS to always point ship at their targets (docking port always point at each other)!!!
4. USE your Nav Ball - Understand how your RCS thrusting moves your Prograde indicator so it lines up with target indicator
(note: relying on the "magic following camera drone" aka external "cheat" view actually makes docking very difficult - using 2D perception to fine tune 3D movement & distance)
5. Now use RCS thruster to start a slow & steady (1-4 m/s) forward movement toward target.
6. As you close in, keep making RCS thrust adjustments to keep prograde & target indicator lined up.
8. Keep your eyes on the Nav Ball and target approach speed indicator.
9. Within 10m slow to under 0.5m/s ... and small RCS adjustments... and at 5m turn off SAS... and .... poof - you've docked.
And we spin in a spiral galaxy so the corkscrew reality as we follow the sun..... evolved reality needs to be taught so people can understand what exactly life is
The helical spiral that the planets follow while orbiting the sun does not affect the orbits of satellites around the earth enough to affect this discussion of orbital mechanics. That topic is more advanced and would needlessly complicate the discussion since it has a very small effect on earth-satellite orbits.

Vacuum effortless any effect while gravity is everything around the satellites and planets. I believe that there'd take into consideration since masses are also into movement so vacuum should work together within awhile distant universe.

In regards to the 6 orbital elements I guess the "time of perigee passage" has been replaced by the "specific angular momentum"?
Hi master is there really an amikus planet?
NO.

Honestly, I think of the folks that compute orbital values, and those calculating intercept calculations for long distance flight, as unadulterated geniuses.

The notion that the Earth revolves around the Sun (Heliocentric mode) had been proposed as early as the 3rd century BC by Aristarchus of Samos...
And before that earth was known to be flat sense humans been on earth. In the 2nd and 3 rd century scientists and astronomers took what the Greeks told them about earth and changed it to heliocentric globe earth which is a model not a real example of earth.
Even that was some knowledge, for that time.
Man learned MORE in the later days, gradually.
The Mayan had all the this figured out 6000 years as well
When was this made? English units? The space shuttle? The Soviet Union?
Do you think that the laws of physics changed from 1990 to now? The math remains the same.
Heliocentric model of Solar System is correct in Physics and Astronomy
It's clarify half of my doubts in satellite orbit. Thanks alot.
👍🏼
Can you cite where you get the the notion that "the ancients believed the Earth to be flat"?
Pariah Sojourner Prophet Muhammad seemed to have thought that the sun went somewhere when it set, and that somewhere was below the throne of Allah. Yet in reality the sun is actually not setting, but rather the Earth is rotating in a certain way so that it seems to be setting. So at that time in Arabia it was believed the earth was flat.
ancient Greeks knew the earth was a sphere over 2,500 years ago.
Verse of the Holy Qur’an , from Surah Al-Anbiya, Ch. No. 21, V. No. 33… That it is Allah, who has created the nights and the day…each one travelling in a orbit, with its own motion.

I have always wondered if it was possible for a lunar orbiter to "slam" into the moon by simply staying in one place along the moon's path around the Earth until the moon completed an orbit?
@Kit Canyon ok, that part I get. Perhaps I should have worded it better. But let's say it is a shuttle or a rocket instead of an orbiter. The rocket stays in one place directly along the moon's orbit until the moon comes back around. At that point, would the rocket then "slam" into the moon even though it was stationary the whole time?

What decides how close a planet orbits to the sun? For example sometimes you see a planet like Jupiter close to the sun and sometimes you see a planet like Jupiter orbit far away depending on the star system? How does that happen?

First how fast is the planet
second how heavy is the star
the position and speed. or, for a single variable, the orbital period.

16:00 We cant orbit at specific latitude? We must pass to ecuator line?
you can, its just that launching from equator due east is going to use more inertia of earths rotation to get into orbit easier.
so its more efficient launching from equator. if you dont want to orbit specific latitude
The orbital plane must intersect the center of mass of the object being orbited.

Question how do you post videos with no internet?
You don't. And this is obviously not a problem for you seeing as you have posted this message.
GREAT DAY I WAS KINDA OF THINKING THE SAME THING AS THE NARRATOR WAS SPEAKING. ENJOY MORE
can something just sit still at a distance from a mass? basically can a moon just sit still in a gravity field from a planet? why does it always circle the planet and can’t it sometimes just sit still at a fixed distance away without circling it?
Gravity attracts evething not matter how far away so if the obkect sits with 0 relative velocity to another object they will ventually crash because of that. So they need to move to not crash
it cannot sit still, gravity would pull the moon inwards. by moving sideways fast enough that pull turns into sideways motion itself.
People tend to think that when things are "in space" they are "weightless", this is not a fact. For instance if you are at the altitude of the ISS you weigh 88% of what you do on earth at sea level.
The ISS stays on orbit because it is also moving laterally at about 17000 mph so as it falls toward earth it also misses hitting the earth and simply orbits the earth. If you went straight up to 240 miles high, and stopped, you would start falling and hit the earth again , moving at thousands of miles per hour

how planet rotate the sun?
what is the reason of rotation?
is planet axis is motor or orbit is track where planet most go on this imaginary circle line?
and why sun does not rotate?
honestly i dont know anything?
Richard Dawkins disliked your comment.
@Hal 9000it's not about ignor neither my inability.. if u have a good knowledge than explain me why sun doesn't rotate.?
Iam just shock man.
1. planets orbit other objects because they move sideways as the object pulls on them, cancelling out the sideways momentum but now the downwards pull is sideways itself. rinse and repeat.
2. no reason, not everything has reason to it, they have causes but not reasons.
3. trajectories are not constant, they change all the time.
4. it does, you can track this using sunspots.

Why stewie griffin is reading Newton’s laws?
can someone tell me why venus spins the opposite way to all the other planets and whether the moon spins at all ?
There is no consensus on why Venus spins the opposite way. The most common hypothesis is that it doesn't spin the opposite way; there was just a collision of some sort that knocked Venus upside down. Other hypotheses include tidal forces from the sun.
Yes, our moon spins, but since it is tidally locked with Earth, the rotational period is equal to its orbital period (which is the case for most moons in the solar system).
@@willoughbykrenzteinburg thanks for that , venus getting flipped over makes sense but i still think the moon doesnt spin, if it did there would be no dark side , different countries on the earth would see a different view of the moon , surely?
@@NOT_SURE.. the moon most certainly spins. We see the same side because for every degree of rotates, it has traveled around in orbit that same amount. If you were on the moon, the sun and stars would rise and set just like on Earth. Just everyy 27.3 days or so. It is rotating for certain.
The moon doesnt have a dark side. The side of the moon we never see gets just as much light as the side facing us.
Venus somehow is upside down, that’s all. Technically, it may not be. We can’t see the actual body. The clouds may just be going that way.
There is no dark side of the moon.

Isaac Newton sounds like Stewie Griffin.
Well this made sense more than flatspacers and flatearthers believe, but still limited on their understandings of Gravity and Magnetism. I don't think human's have the capacity to comprehend the idea there could be an Implosion field near the center of their planet causing acceleration with lagforce that causes weight when not in the state of Free Fall. It is nessisary to have this attracting implosion field to pull on moon's and planet's with an outwards force also from their circular motions in order to have an elliptical orbit path. So the differential between orbit and rotation would cause the "g"constant:(Orbit÷(Rotation×2))=
"g".
And so: (Orbit÷(Rotation×g))=d.
The rate the sun's pull is diverted to the center of earth to pull on it's surface of the planet as an implosion field with acceleration who's lagforce causes weight.
It has taken a very long time and man hasn't figured thiis out yet.
It's because theories are a mental block.
There are no flat earthers, they just want to comment like that to create nonsense
