How We Proved Earth Rotates Using a Giant Swinging Ball

[@rammerstheman]

This is really hard to visualise unless you imagine the experiment on the poles. A little animation would probably have helped demonstrate the principle in action.

[@BeastlyKings]

rammerstheman agreed, he lost me at "the room rotates around the pendulum". How? I thought it was Coriolis effect on the pendulum? I can see if you were on a pole, yes, the room would turn. But what if I'm on The equator? How does it work then? I'm disappointed in this video and it's lack of clear explanation. It's telling me things, but not actually explaining the "why". Now I have to find another video that does it better..

[@seeker296]

Wait so how is it a proof that the earth rotates? Or maybe more accurately, how can we say the room spins around the string? Rooms don't spin on earth. They maintain their orientation relative to the planet and rotate around the center of their plane of rotation across the same plane all the time

[@nAhSTER87]

And he said over time, the pendulum changed directions so how does that explain earth rotation in one direction only? Earth is a flat plane.

[@theblinkingbrownie4654]

Took me a while to get but I think I got it. Imagine the pendulum swinging at the north pole, obviously the pendulum would appear to be rotating then due to both sides (i say 'sides', I mean each half perpendicular to the plane the pendulum is rotating at that point in time) rotating in the same direction. Now try moving the pendulum close to the equator, even though now both sides rotate in different directions, it doesnt cancel out as the side closer to the equator rotates faster than the one closer to the pole, thus it rotates just slower. And on the equator 0 rotation due to cancelling out. If anyone can see that Im wrong please tell! It's my first time being introduced to this concept.

Same here but I have found any flat-earth believers. It must be too early for that.

[@bryanlin982]

nope, all i see is flat earthers

[@chuckhough]

haha. Here i am. Why does this effect a pendulum but not an airplane? Not a hot air balloon? Pilots don't correct for this. In fact for ease they use maps and are told to act as if they are flying over a flat plane (not saying this proves a flat earth!). So if there's a noticeable effect on a small pendulum going a tiny distance the effect should be huge on a plane or a balloon. But..it's not. And this idea about dropping a coin from a tall building and measuring the earth spin. Total nonsense.

[@Porkey_Minch]

I wish they had showed an animation of the pendulum swinging, because I can't really visualise how it works

[@B.B.1961]

Don't worry, it's all falsehood anyway!

[@goldenrule4408]

Question? If you can drop a ball off of a building and it lands of to the side due to the earth spinning, then why do hot air ballons that hover for 3 to 4 hours come back down in pretty much the same spot. When the earth is spinning 1000 mph, it should be 3000 to 4000 miles away?

[@daltonc.5720]

It’s because the air surrounding a ballon is moving with the earth as well and the ballon is light enough to be affected by said air where as a falling object has too much inertia for this to happen. :)

[@JustWasted3HoursHere]

The Eötvös effect is an even better proof that we rotate: Discovered in the early 1900s, it showed that objects weigh LESS when they travel east and MORE when they traveled west. On a spinning Earth it makes perfect sense: As you travel east you are traveling in the direction of spin, adding to your slight centrifugal force, pulling you slightly more away from the Earth, making you weigh less. Traveling west does the opposite (subtracting from your centrifugal force, making you weigh more). And to prove that we are on a sphere, this effect is MOST pronounced at the equator and LEAST pronounced at the poles. If, for example, the Earth was flat....even if it was rotating, the most pronounced effect would be at the "edge", not the equator. Another interesting thing about the Foucault pendulum is that they make one complete revolution per day _at the poles_ (in opposite directions when viewed from ground level, but in the SAME direction when viewed from a globe perspective), but as you get closer to the equator they make less and less of a revolution. On the equator they make NO revolutions.

[@hahnkf8111]

The effect you’re referring to is actually most pronounced at the poles and least pronounced at the equator. Centrifugal force is strongest towards the center, that’s why it moves things outward. In other words spinning in an office chair once per day with your arm sticking out is actually more pronounced than being on the equator.

[@JustWasted3HoursHere]

@@hahnkf8111 No, the Eötvös Effect is zero at the poles since the change in apparent weight is the result of your velocity added to or subtracted from the Earth's rotation. This is why measurements of this effect are always done on paths that are close to or at the equator.

[@JustWasted3HoursHere]

@James Henry Smith Check my channel.

[@LuisAngel-sb8xd]

The foucault only works because it uses cheats. The experiment has been refuted since it was made. The Earth doesn't rotate, it's the wind that goes around it, just like the moonsized sun.

[@ericbilodeau3897]

"Something moving in the northern hemisphere will look like it's being pushed to the right. And something moving in the southern hemisphere will look like it's being pushed to the left." 1:48 Correction: only if the movement is northward. Something moving northward in the northern hemisphere will look like its moving to the right and something moving southward in the northern hemisphere will look like its moving left. While eastward and westward will not be effected. In the southern hemisphere it is opposite for the north/south And if you cross the equator in either case the direction will reverse

[@Gerard1971]

You're wrong, as it is stated in the video is 100% correct. You have to look at this from the location from which the object is launched. On the northern hemisphere the object will appear to deflect to the right, regardless of whether it was launched northward (object appears to deflect eastward) or southward (object appears to deflect westward).

[@crashlanding9938]

This video taught me that scientists still try to prove things they already know.

[@killerful]

Even BOB did not realize that we measure earth rotation tens of thousands of times a day everyday worldwide. Modern aircraft test the onboard FOGs using earth rotation as the stimulus as part of the pre-flight test. The process is referred to "Inertial Reference Unit Alignment" even though they are not really aligning things, just verifying the FOGs.

[@kirkthiets2771]

I'm a journeyman carpenter. I've built more than a half dozen 16 story highrise condominiums and the stairwell and elevator cores within them. We generally used lasers for checking plumb but we also reverted back to plain old fashioned plumb bobs. We used an extremely large 20 pound plumb job a on a couple jobs in Denver. I've had argument after arguement on this subject but you have to have a guy stop it from moving at the bottom when ever you intend to use it. The earth wobbles as it rotates. No matter how still the air is in the shaft, especially after you get higher than 8 stories high, the damn thing starts moving all by its damn self. Not only can you see the pendulum swing back and forth in an arc over a day you can also see it wobble as well.

You have confirmation bias. What you are observing does not mean earth is a spinning ball.

There aren't, nobody has ever gotten outside of the Earth, regardless of shape.

[@mattc7939]

On critical thing missing from the video is the rate of change is predictable (flat earthers say the pendulums are unpredictable...which is completely false). The rate of change is 15 (degrees) sin (latitude). This works anywhere on earth, and the rotation is clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. If the earth were really flat, and flat earthers really wanted to "debunk" it, then flat earthers would have to explain why this very precise mathematical phenomenon exists, either that or actually demonstrate that it doesn't. (But is does...I've tested it personally. My office is literally meters from one)

[@ArtInMotionStudios]

I am curious, wouldn't this mean that there is a place on earth where if it was swung in a perfectly aligned direction to the rotation of the earth along its equator it would just swing back and forth perfectly? btw many flat earthers often do believe the earth rotates just not the same way because it's a spinning disk, so they would most likely see this effect as a result of that so would not show them anything new. most of them are aware of these effects,

[@AWildBard]

maybe if it was swinging east to west? but actually, the earth is tilted, and this changes over the year, so the only time it wouldn't change would probably be when the sun is over the equator during the equinoxes in march and september. not sure if being on the equator would really negate the effect or not. it's an interesting question what would happen on the north or south pole? where would the swing be stronger or weaker? I don't know

[@LuisAngel-sb8xd]

Real fes don't use any excuse regarding motion Earth, it's stationary and this experiment uses tricks to mantain its consistency, while it actually doesn't prove anything. It was debunked since it was made. Everything else is associated with wind motion and other factors.

Without adding judgement, I have a question. Wouldn't pendula and cannons behave the same if the earth were an oblate spheroid, like it is now? And if it is, what if the earth were severely flattened at the poles, but still spinning? Same situation, right? Coriolis is going to apply to any spinning shape, even a disc. It's safe to say, then, that this doesn't prove we're on a sphere, but it does prove we are spinning.

Jet fuel may not be able to melt steel beams, but it can heat steel beams to a temperature where they are completely useless as beams, and would collapse when supporting a load. A steel worker has a demonstration, where he heats steel to the temperature of jet fuel, and shows that it is still solid as a rock. But unlike the cold steel rod, the heated steel rod bends like a wet noodle.

[@dogboy2613]

There's a bit of a mistake around 2:00 While it's true that the Earth is wider around the equator, it is only relevant that the Earth is widest around the equator with respect to Earth's axis of rotation. A person standing on the equator has a much longer distance to travel in 24 hours when compared to a person standing near the north pole. This is because the person on the equator is further from the axis of rotation, it is insignificant that the Earth has a 43km bulge at the equator.

Here's a pic from the Curiosity rover: www.nasa.gov/jpl/msl/earth-view-from-mars-20140206 Hubble can't take a photo of Earth because it's too close to the surface. It orbits Earth 15 times a day, which means it's moving very fast relative to the surface, and the tracking system is only designed to track slow moving stars. If it took a photo it would just end up as a streaky blur.

Re: Riccioli's hypothesis, is there a point where the Coriolis effect would be canceled out by the prograde rotation of the earth? In other words, with the earth rotating, would a cannonball shot due north ever curve to the left? As in, earth's west to east rotation is greater than the increased velocity from where the cannonball was fired (closer to the equator), so the cannon ball would land in a more westerly location than when it was fired... or, "curved left"? Or is it always relative?

@@massimookissed1023 Refraction and many other scientificallt accepted factors, the light of the Sun in a fe is projected similarly to a concave len, that may lead you to a closer understanding. There are also many instances where that event doesnt actuallt ocurr, where I live I have not seen the clouds being lightened underside, and the sun becomes smaller in the horizon until it fades. This depends on where you live, the conditions of the air, etc. Not necessarily proof in favor or against fe, although I know for a fact it is stationary, that won't change.

It can't be sudden, bc then there is no F-ing way we went to the moon, you'd get sling shotted the second you crossed this barrier.. And if it's gradual how come balloons at 100,000 feet still appear to "turn with the earth"? Wouldnt the friction at 100,000 feet be way less, wouldn't that air not be spinning as quickly as 1000mph. Yet the balloon doesnt watch the world spin underneath.
