Is the Earth Really Round? | My Amazing Earth | BBC Earth Science

[@thekingoffailure9967]

If you made a globe that is a perfect oblate spheroid with that 40 km distance and put it next to a perfect sphere globe, could anyone tell the difference? I doubt it.

[@ompabaletserametse8643]

You are correct. Scalling down the earth will give you a smoother and more round shape than the perfect sphere.

[@marcelwolfe7495]

😂😂😂 got this recommendation after watching a bbc video about trains needing a flat surface to properly work.

[@SpaceisAce]

Great that you covered this, I too made a video recently about how the Earth isnt round... and in comparison focusing on how Neutron Stars are the most perfectly round spheres in the known universe!!

[@sugathdammika603]

Thanks so much for this video...❤️❤️

[@artortiz3274]

I knew it was oblate spheroid

[@-jeff-]

With 42km being a small fraction of Earth's 40,000km circumference I'll give it the benifit of the doubt and call it round.

[@TVARecordings]

45.000km to be more precise. Imagine how many rides around the earth your car has driven. A Tesla would easily do 7 cycles around the equator

@@TVARecordings 45 000 km??? Sorry? By definition from the Equator to one Pole there are exactly 10 000 km. So, the circumpherence is 40 000 km.

[@TVARecordings]

@ Last week, and I’ve rechecked it. In Dutch papers they’re claiming that the Equator is approx 45.000km.

[@TVARecordings]

Sorry, i think I’ve made a mistake. You’re measuring vertical, from north to south. I’ve meant measuring horizontal.

@@TVARecordings The Equator is SLIGHTLY larger. 40 075 km. And, well, they didn't measure the from pole to pole distance, so the north south circumpherence is, in fact, 40 007 km. So, a difference of 68 km over 40 000. About a 0,17%

[@warmachineuk]

Round, when applied to Earth, is not a precise term and does not mean only spherical. If a speaker wants to describe a more precise shape, he uses a precise term, not one known to be approximate. To say the Earth is not round because it bulges a bit is to ignore commonly understood English. That's the kind of trick con artists, trolls, and conspiracy loons use and, so, should be avoided.

[@Chase_baker_1996]

Short answer : Not exactly

[@Chase_baker_1996]

@James Henry Smith yes it is and if you disagree show me a working model that works

[@adamkou5475]

0.34 percent bulgier around the equator? That sounds pretty perfectly round to me.

[@fidelcatsro6948]

[@scott5146]

I'd have thought someone standing on the equator is waaay closer to the moon than someone on the north pole. More like 6400km closer than 20km!!

It also depends on the position of the moon. That orbit animation with it dodging the mountain triggered me as well!

[@GraveUypo]

you're right. and the moon slightly larger (in angular size, of course) when it's directly overhead as opposed to when it's on the horizon. iirc it's about 2% larger

Or farther, depending on the moment of the day. They should have compared with the antypodes or with the centre of the Earth.

[@kirkc9643]

Of course not. It's an oblate spheroid

[@TheCitizenPain]

This sort of exaggerated nonsense is how people end up being woefully misinformed and not understanding the realities of the world. The earth is as perfectly spherical as a snooker ball. The deviances you show in this video are utterly negligible on the scale of the planet. The earth is a sphere, and as close to a perfect sphere as to be indistinguishable for any reasonable purpose.

[@Graytail]

Were it the size of a snooker ball, it would be perfectly spherical and perfectly smooth, yes. Blow a snooker ball up to the size of a planet and it'd likley be just as topographically featured as the earth. Start it spinning, and its equator would bulge in time.

[@brightax7502]

ok good this comment is actually facts unlike the rest that keep saying bbc is BS

[@EPICSOUNDTRAX]

​@@Graytailremove atmosphere and oceans and look how close the a ball is This is complete nonsense. The earth looks like a ball because of an optical illusion not because it is

[@meixo9083]

How come BBC bring new theory about Mount Everest is not being tallest mountain but there are still BBC reporters climbing Everest thinking it's the tallest in the world. You guys are so confusing yourselves.

[@murk1e]

Its a bad video, but this is wilful misunderstanding. It is highest referencing sea level, but its peak is not farthest from planetary centre.

[@RomoBomo]

Mount Everest is the highest mountain from sea level. Chimborazo is only higher because the land around it is also higher, it's still smaller than Everest as a mountain. Major difference.

[@ericsturm8047]

You still would need to measure the height of a mountain from sea level. Who is going to start climbing from the center of the planet? Right?

Chapter An-Nazi'at (79), Verse: 30 وَالْأَرْضَ بَعْدَ ذَٰلِكَ دَحَاهَا In English it is translated: “And after that, the earth: wide has He spread its expanse” amazingly, the word “دَحَاهَا” can also be translated: ”extended in egg shape.” so the translation can be: “And the earth, moreover, hath he extended in egg shape.” either way, both translations are correct. more amazingly, the word “دَحَا” (dahaa) is derived from word “دحية” (duhyah) wich specifically means ”egg of ostrich” (not just any egg). Come to the right path my fellow brother and sister of human.

The man needs to be told he may have a bunch of science types watching his reports, and he better not get a single thing wrong. In particular, mathematical errors.

Kurt Lambeck, you need to go back to school mate... comparing the earth to a rugby ball? A RUGBY BALL? That is upto twice as long as it is tall, and it has a circular cross section, the thing is a damn air torpeedo. How about comparing it to a cream filled donut, thats a closer shape than a damn rugby ball. A slightly squashed orange perhaps? Hell a fat flying saucer would be a better description! A rugby ball is a prolate spheroid, not an oblate spheroid.

[@MossyMozart]

Stand down. It's a metaphor.

[@alfreshluque3297]

Why would someone make it round and make people believe it is 🙄

[@guff9567]

How can a sphere be round?. Only a flat object can be round

[@moggpiano8043]

Dictionary definition.... 1. shaped like a circle or cylinder. "she was seated at a small round table. 2. *shaped like a sphere.* "a round glass ball" Perhaps you are confusing "round" with "circle". Even then you are wrong. A circle is two dimensional. It does not exist in 3D. An "object" would have three dimensions. Therefore in the case of the Earth, the flat model (assuming the underside would be similar to the topside) would be a disc. The "round" Earth would be a sphere. A disc resembles a circle when seen from directly above or below. A sphere resembles a circle from any angle.

[@guff9567]

@@moggpiano8043 why say a ball is round? It's a ball, and therefore spherical by default

This guy, Kurt Lambeck, has never in his life seen a rugby ball. «the short axis is the rotational axis and the long axis in the equatorial plane». Ok. A rugby ball has: ONE long axis and INFINITE short axis, so it can rotate easily around the long one. The earth has ONE short axis and INFINITE long axis, so it can rotate easily around the short one. I mean, try to imaginate a rugby ball rotating around a short axis. It would be la having it on a table and making it spin while flat. That's NOTHING like what earth looks like. In fact, if you make it spin fast enough, it will try to stand and rotate around the long axis, the stable one.

Have you really heard yourselves? «A person standing on the Equator is 20 km closer to the Moon than one standin on the Pole». Do you mean the Moon sorrounds the Earth? That the Earth is inside an empty Moon? Otherwise this statement makes no sense.

[@kilimanjaro1893]

Lmao, you really don't get it?

@@kilimanjaro1893 A person on the Equator is 20 km farther of the centre of the Earth than one standing on the Pole. That is correct. The other one is nonsense. It's perfect to confuse kids, for example, who will think physics is weird. Who will even ask «what if its during the day and the Moon is in the other side of the Earth?»

[@kilimanjaro1893]

@ bruh, is that what u are confused about? Ofc if the moon is on the other side it will be farther LMAO. What the video meant is that if the moon is NOT on the other side but facing both the person from the pole and the equator, the person in the equator will be 20km closer than the person on the pole.

@@kilimanjaro1893 Of course the person on the equator will not be 20 km closer.The Earth radius is 6 378 km on the Equator. There's at least this difference. Unless, as I've said, the Moon is an empty sphere and we are inside it.
