How can a plane land at southpole's center right-side up instead of upside down?

I still don't understand. And how would it be a mistake for me to say that I would, for myslef with my own eyes, see a small toy plane parked underneath a basketball,.. assuming that the Basketball had a gravitational pull and core.

You wrote: "It would be grounded the right way up on the ball- wheels touching the surface, just as it would anywhere." No it wouldn't. Not if it's up-side down. The wheels and plane would be grounded just as it would anywhere, yes, but it would stand in accodance to it's position on the ball.

Imagine being in space flying towards Earth, towards the under-side of the globe, then landing. You'd land right-side up but how can that be. The basketball sim contradicts this, it's not irrelevant to assimilate both the Earth and the ball in the same light. They're both round, both have the same gravity capacity but on one ball, if I landed underneath it, I would be upside down but on the other ball, I'd be right-side up?

Still don't get it.

You're not paying attention.

"You wrote: "It would be grounded the right way up on the ball- wheels touching the surface, just as it would anywhere." No it wouldn't. Not if it's up-side down."

No! It's only upside down according to you. Forget about you and view everything from the point of view of the basketball- forget that you and the basketball are on the REAL Earth inside the real Earth's gravity and pretend the basketball is in space. Up and down are calibrated from the centre of the basketball. 'Down' is towards the centre, 'up' is away from it.

Hence, a toy plane on the 'bottom' (from your view) of the basketball is just as much the right way up on the basketball as one on the 'top'. They are both wheels on the surface, being pulled towards the centre of the ball, and hence towwards the surface, which to both planes would be 'down'.

So your mistake is to be using your own personal feel for up and down when looking at the plane and relate it to whether the plane is the right way up or not.

"Imagine being in space flying towards Earth, towards the under-side of the globe, then landing. You'd land right-side up but how can that be. "

Assuming that you define the underside as the one that looks lowest to you when you approach the Earth- because, of course, you could approach the Earth, in space, from any damn angle you liked, as there is no central reference for up and down there- then if you deliberately headed for what you saw as the underside, unless you turned your ship over you wouldn't land the right way up at all. You would come into the atmosphere upside down and you would very quickly feel gravity pulling yourself towards the top of your ship and it would soon be exactly as if you had just inverted an aeroplane in the air.

The answers you are getting are perfectly logical; you just need to look at them properly. Your very question shows the problem you are having- why is the South Pole any different to any other part of the p;anet? It's all the same.

Meanwhile, debbie- the essence of navigation- starting with the stars, and eventually moving on to the operations of compasses- all contribute towards everyone having developed a universal sense of North, which we naturally associate with 'up'.

THIS THREAD HAS BECOME SCARY AND STRANGE, JADE, USH AND I ANSWERED IT IN THE FIRST THREE POSTS - IT IS NOW THREE PAGES LONG - INSANE 🙁

I got the feeling that he needed it all in one post. My point about the relativity of his viewpoint I thought went well with comments like yourss already made, but he seems to see them in isolation instead.

perhaps, I still find it scary though Ush.

Are you sure about that? What about in space.

what about in space...what do you think keeps the planets moving around the sun?

the moon moving around the earth?

entire galaxies spinning around a centre?

the tracjectory of comets?

all of it is because of gravitational forces

Tragic.

Isn't this the sort of thing you wonder when you are about 4 years old?

Any good air plane pilot would never fly upside down when it wants to land the plane...what kind of a question is this?

Ok, Ush. I think you've somewhat cleared it up a for me now. Let me offer my interpretation of what I read what you wrote to see if im correctly understanding what you wrote:

There is no up and down in terms of the planet's sphere. Down is the towards planet's core and up is anywhere on the planet's surface.

Ok, so if, from space, I flew into the direction of the underside of the planet where eventually the planet was under me., I would enter the atmosphere as normally as anywhere else on the planet because somehow gravity would tell my mind and body that my plane is right-side up. But what I dont get is the physical position of the plane itself at the point of entry. Does the plane have to shift in accordance to the gravity.... I would enter Earth and then 'Id manuver my ship.....

lol you know what forget it, Ush. Just close this thread already.

I'm just asking to be flammed ain't I, lol

I'm done.

Like I said, if you deliberately aimed for what you saw as the undersaide of the planet... then no, you would 't suddenly flip over, you would enter the atmosphere with the ground- and gravity- above you, exactly as if you were in an aeroplane and torlled it over onto its back. You would be upside down.

You wouldn't have been feeling any gravity at all in space, but when you entered into the planet, you would feel gravity pulling what to your mind would be up[wards. Soon your natural sense of balance would assert itself and you would have no difficulty in realising that you are flying upside down.

But I always wondered if people who lived way down near the south pole had their globes turned upside down.....I just think differently...

I look things a little differently as you know sometimes... 😄

So then you would have to manuver your ship rightside up then.

So inside on Earth, lets say the underside, your plane would be right side up to you, the pilot. but if seen from space, the plane would be seen as upside down.

I rememeber the scene in "Star Wars Ep. II-AOTC" during the beginning of the movie, and right after the crawl, Queen Amidala and her ship and crew entered Coruscant through the underside of the city-planet and the ship had to flip upside down to enter because entering the way the ship was, which was flying rightside up to us, in space, would've ended up upside down in the planet. I see now. Gravity takes care of it all I guess.

Right?

What the hell? Just seriously.

Why is anyone doing humanity the injustice of trying to explain to someone why, if you fly around the Earth, you won't end up upside down?

Just asking.

Because we care enough about others to wish to educate them 🙂

Well considering you have to be over 13 to join and he's still asking about how basic gravity works, by saying "If a plane flies around the world does it end up upseide down", does he deserve responses?

Just curious.

merely trying to educate the tards...and failing miserabley i'll admit...

I always believed 'Tards didn't deserve it. Of this level and age at least.

Everyone deserves an education its a basic right - the failiure of some early on does not mean their attempts at self improvement should be thwarted by elitism. 😉

Asking Why is the first step to wisdom AC.
