[@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..

[@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.

[@scarkillerful]

Mark London And that is a good thing. It means that they don't take things for granted, as the flattards seem to suggest.

[@theVoluminousPoo]

Exactly. The theory needs to be repeatable and reliable. Otherwise we'd still be using the four humors as a base for medical knowledge. Or who knows what else.

[@cortster12]

[@theVoluminousPoo]

Sponge Robert :True, our knowledge is only as applicable as our current understanding holds. Who knows what things will come to be known as false as time goes on.

[@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.

It’s not that they lack the knowledge, they just enjoy getting attention for being different and contradictory to others. The flat earth movement should NOT be viewed as anti-science, but more as a psychological personality and state of mind.

Imagine believing the focault pendulum isnt powered by electricity

[@julesdomes6064]

Randy Layhey - Even if it is, that will not make our globe flat.

[@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.

"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).

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. :)

[@redneckhippiefreak]

Im still trying to figure out how the cannon ball moves to the right? If the earth is turning towards the East wouldn't the cannon ball appear to move left as the earth travels to the right under it? The target is connected to the earth, that is moving Right..Or is it that the velocity pushes the projectile faster to the right? Confused ..

[@CallMeNiel]

I was thinking the same thing. I'm not sure if there was an error in the video or if I'm somehow thinking of this the wrong way.

[@BKPrice]

Say at the Equator you are naturally moving 100mph east with the earth. Near the pole they might then be moving about 10mph with the earth, and each point in between is some decreasing speed going from 100 to 10. If you shoot a cannonball at the equator its east velocity is and remains 100 mph from the the initial point, but if it made it to the place moving 10 mph it would still be going around 100 mph in an eastward direction along with its northward velocity, although it might slow down with wind resistance. Since the surface of the earth would only be going 10 mph at that location, the cannonball would of a necessity move to the east relative to the surface of the earth. Note, the above aren't intended to be accurate numbers, just to show the concept.

[@mikemental8285]

Bob, from Globebusters proved earth's rotation. 15° per hour. Thanks Bob. R.i.p.

[@stuartgray5877]

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.

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.

[@Kaervek87]

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?

The secret of success is...find out what everyone else is doing, then run the other way. If everyone believes the Earth is spinning, then we likely live on a pancake. Yum. I bet the oceans were once made of syrup.

I am not even watching the video, I am just looking for flat Earthers' responses in the comments.

[@peaceandwealthseeker4504]

This is no way proves earth is spinning

[@detectivel2231]

Truth Seeker He explained this to you very well and you are to dumb to understand it?!?

[@peaceandwealthseeker4504]

くださいあなたの心に従って I actually overstand in comparison to the author of this. All motion must be observable from a reference frame and earths can never be observed leading us to conclude it’s non existent

[@detectivel2231]

Truth Seeker What so you mean by this?!? We can observe the Motion of the earth when we look at the stars... But that's not the point! You don't need to observe something to Know it's right! How do you think we know the content of the sun? He explained the forces, that pulls the pendulum clockwise in the north and otherwise in the south 💁 Try to explain this on a Flat, stationary earth

[@massimookissed1023]

There is not a single "Truth Seeker" on the internet with the slightest interest in the truth.

[@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.

[@crazy-cris1236]

0:05 "earth moves several hundred meters per second" 3:15 "if you drop a ball from 74 meters up when it lands it will be one centimeter to the side" {considering a 74 meter would sure stay in the air as long a second so technically if earth was rotating that fast it would be farther away from where you dropped it it moving a centimeter away because the wind and you can't drop a ball perfectly} Scishow please explain if you are reading this

[@detectivel2231]

Crazy-cris12 The bottom of the tower was spinning with this Speed, but the top of the tower was slightly faster, so the ball was also only a short distance further 💁

[@aranha1504]

Dude, you can easily understand this if you get in a truck and jump while its moving, or jump while ur in a plane at cruise speed, the plane is moving almost at 1000kmh and you still wont feel a thing, you will jump and land on the exactly same spot.. it doesn't matter if the earth is moving at 1000mph or 1000000mph, the only reason that makes that ball moves 1cm to the side its because of the tiny difference of speeds between the top of the tower and the bottom.

[@LuisAngel-sb8xd]

Never sacrifice your common sense. The Earth doesn't rotate, even the Pendulum has been debunked since its conception!

[@hiphop7103]

The earth doesn't fuc_ing move not even once a day.

[@Poseidon6363]

Our planet revolves half as fast as the hour hand on a clock, one revolution per 24 hours, flattards think this is fast lol.

[@warmachineuk]

I came here looking for the flat Earthers. I was not disappointed.

[@AlejandroParis]

So... let me know if I understood, because I don't know if I see it clear. I've been thinking for a while, and this is what I came up with. Is it correct? -A pendulum oscilates, for instance, N-S direction, between two opposite positions, each of them on a different latitude. -Right in the middle, there is the point on the ceiling it hangs from. The pendulum has the same linear speed when rotating with the Earth as the point from which it hangs. -When it is closer to a Pole, the ground underneath has a lower linear speed; when it is closer to the Equator, the ground underneath has a larger linear speed. -Then, if it is closer to the Pole, it will be moving "faster" compared to the ground underneath; if it is closer to the Equator, it will be moving "slower". This means when moving between the middle towards the Pole, it will slowly get ahead to East; while if it moves from the middle towards the Equator will stay behind to West. -As a result, you see a clockwise rotation on North Hemisphere, counter-clockwise rotation on South Hemisphere. QUESTIONS: -Is this the right explanation at all? It just made sense in my mind but I may be totally wrong. -If this was right, would its oscillation trajectory turn faster when it is more perpendicular to the Equator (N-S direction) and slower when going paralell to the Equator (E-W direction)? If someone knows anything about this... I would be very grateful to fully understand it! Thanks!

[@narke2667]

1. There is nothing else to explain it. 2. No, colser to equiter means slower spin becouse you are further away from earth's axis. Tho I'm not sure.

[@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.

[@michaeltemperato7300]

*If this is true, then it should apply to planes as well,* however, heliocentrists conclusively play both sides of this fence by claiming *objects in motion retain their velocity relative to the earths rotation,* or as you quoted as commonly called "the Coriolis effect.", thus proving the earth moves; but then when faced with problems concerning the physics of planes on a sphere (containing *both* the initial velocity of the earth rotation, it's acceleration through the air, and somehow landing on a moving earth), were told *they move with the atmosphere due to "friction" caused by gravity.* The Coriolis effect & the rotating atmosphere stuck to earth *cannot both be true.* I really wonder when people will just accept that while FE and those who believe it *don't have a fully functioning model;* the current one *doesn't function correctly either.* The globe model has some serious scientific anomalies that are simply explained away and unaddressed. *Such as this contradiction right here.*

[@tmrv2974]
