Earth Not Rotating

1. In school i was taught that at the center of the earth, there is a solid magnetic iron core, that is surrounded by liquid molten magma. If the core is indeed iron and iron is placed into a blast furnace and it melts, and the solid core is iron, then why doesn't the the core melt if it is surrounded by liquid magma ?

The high pressure increases the melting point of iron.

2. How does anyone know that the core is solid, if nobody has been to the core ?

Scientists can detect the different layers withing the earth by the way seismic waves from earthquakes refract and reflect.

3. If the earth didn't rotate, then why couldn't a rocket come straight down from space ?

It could.

4. If all of the planets and moons in our solar system rotate and there is no fixed point, then how is the rotational speed of the earth and other planets and moons determined ?

By relation to the distant fixed stars.

5. If the earth rotates, does this mean that the core rotates ? And based on the earths rotation, is there a mathematical calculation that can be used to determine the size of the core ?

The core rotates very slightly faster than the rest of the planet. This is caused by angular momentum transfer from the circulation of magma.

6. I know that researchers have done drilling and core sampling on earth and astronauts have picked up moon rocks, why haven't scientists done core sampling on the moon ? Are they wary that if core sampling was done, this might change tidal action on earth ?

Could be because there are no geologists on the moon. No, it would not affect the tides.

Cant do this too often!

Nice post(s)!

Rixter, thanks for the answers.

This might help with your first question...

You are generally very right. I have some one comment only: In the ancient times, the celestial phenomena could as well be explained with a geo-centric model, given that one could take account of epicycles (https://en.wikipedia.org/wiki/Deferent_and_epicycle) as Ptolemy proposed. Of course adding one extra parameter in the theory made it more complicated than just adopting a heliocentric system (as first Aristarchos proposed), but that fit better with the "natural" idea that earth is the center - and sole purpose - of creation. Back at that time, the accuracy of measurements couldn't reveal any difference in the star positions during earth's movement around the sun, so at that time, the geocentric model was as viable (even in scientific terms) as the heliocentric one. You couldn't accuse anybody back at that time for adopting this or that model, and the magic of ancient Greek mentality, is that nobody would be persecuted for preaching about it. For sure, if they were presented with better measurements, they would all agree about which model fits better with reality. Compare this with the present, where neo-magical theories pop-up every now and then. Of course ancient Greeks would be eager to mix science with philosophy when data was not available: They would conclude that this or that theory holds, because it fits better with a given philosophical system. One example is the idea that the "perfect shape" is the sphere, so it is "normal" that earth should be spherical, even if this weren't inspired from the fact that all near celestial objects appear to be spherical as well. Anyway, it is sad that people who didn't do their homework during their school years and were left behind even in the merest scientific knowledge (and also maybe having been bullied as being "stupid"), now try to take "revenge" by considering themselves the holders of the only true and pure knowledge, while everybody else is either conspiring or being brainwashed. I'm sure there are people who really believe that the ultimate answer about Life, Universe and Everything is 42, and that NASA, Church and Sionists are hiding it from the masses.

You are so right...

Sometimes I subscribe to this philosophy, "Better to remain silent and be thought a fool than to speak and remove all doubt."

Perhaps, not as often as I should.

Lyn, I thought I would reply as a,,

A. I never heard of, The Flat Earth Society. Do they have a headquarters, secret handshake, Uniforms, flags, code of conduct, membership requirements, etc.?

B. If the earth was indeed flat, does this mean that space is flat too ?

C. If the earth is flat, then why are so many communication satellites required. ? It seems if the earth was flat, then one satellite should be able to be accessed from all points.

D. Whose job is it to feed and cleanup after the elephant's and turtles that are supporting the earth ?

What would keep the satellite up?

Since there is no gravity (the earth sucks), the satellite would be out of range of the vacuum!

I can see some of the advocates of flat earth, and no spin earth arguing with a fence post out in the middle of nowhere.

Tony,

A. The Flat Earth Society does exist.

The Flat Earth Society - Index

They can usually be recognized by their hats.

B. I don't think it does, but I've never been there.

C. Agreed!

D. That's the job of the inhabitants of the Stig.

Comment #103 was directed to Massey. His tin foil hat may have blocked it though.

You're not a pilot are you? If so, and you believed what you just wrote, you'd be perpetually lost without electronic navigation aids.

Hooker

Don't mean to insult you but your post is ridiculous and funny too.

Ummm, lemme guess. You don't believe in the south and north poles in a magnet or in the magnetic flux lines that can be described by a magnet and iron filings in a simple high school science experiment.

Hooker - buying drinks for me and Lyn

Thanks, buddy!

Hopefully, I can return the favor someday.

Magnetic field lines are only parallel on the magnetic equator. To the north and south the north and south seeking pole (respectively) dip down. Pilots are well familiar with this. When you bank into a turn, the plane is no longer level and the magnetic field dip causes a compass error, called the Northerly Turning Error.

Yeah, I'm a pilot so I get all that, which includes precession and, for navigation, variation, east and west.

The point I was trying to make was that magnetic flux lines are not limited to a 2D plane, but are spherical around the magnet's axis of the north south poles.

Anyway, it's all another indication that we are not on a flat earth. And between magnets and precise chronographs and a basic understanding of a spherical earth made way for world wide navigation. And the development of the lat/long system and different map projections.

Hooker

How Does a Compass Work? - Live Science

The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the "north" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field.

Top 10 Ways to Know the Earth is Not Flat | SmarterThanThat

If you’ve been next to a port lately, or just strolled down a beach and stared off vacantly into the horizon, you might have, perhaps, noticed a very interesting phenomenon: approaching ships do not just “appear” out of the horizon (like they should have if the world was flat), but rather emerge from beneath the sea.

But – you say – ships do not submerge and rise up again as they approach our view (except in “Pirates of the Caribbean”, but we are hereby assuming that was a fictitious movie). The reason ships appear as if they “emerge from the waves” is because the world is not flat: it’s round.

This is as bad as talking politics.

It's about to drive me to drink.

And parallels are lines that meet in infinity...

It could on both counts, if the flat earth was spinning like a Frisbee.

just saying, you do not want to be on the edge of that Frisbee Earth, if you are, you'd better hang on.

Isn't that what self centred persons are for?

They have a nice spin to it but would never fall!

Isn't that what self centred persons are for?

There's so many possible explanations..... for example.... it could be a politician telling their accomplishments?

Nope. Take the Coriolis effect; the direction of the effect changes depending on location on Earth.

You lost the spirit of the post. But that's ok.

So, you are now further asserting that the topic of conversation has also been turning?

I'm not opposing that one either. I am curious though if you assert it is spinning like a flat frisbee, or more like a spinner dolphin.

Anyone observe any conversational Coriolis?

There comes a time when one gets so anally focused, they miss the picture all together.

if you're still lost, look at the picture.... if that doesn't help. Then I'll be more direct and say, "lighten up".

Aw man, you too, with the weight comments? I'm not out of shape. Round is a shape! 'Lighten up' indeed!

.

My mood by the way is quite 'light', and hasn't been otherwise within the context of this discussion. Sorry if I was bringing you down. I haven't had any recent aspirations toward mood ballast. There is also the possibility it isn't my doing. Have you checked pressure/temp recently in your moodzeplin?

No problem. Words really can't show a gist of the comment, can it. Frankly, it's hard to take this thread serious to begin with.

I like that answer very much. Not that Flat-earthers can understand either concept.

Somebody please tell me where the edges of the flat earth are!!

I ask because if I have another opportunity to fly around the world I wanna know when I go into space.

Or is there some conspiratorial mechanism that instantly puts me on the opposite edge?

Hooker

In the mean time.... you'd better put this on.

Oh?? So they can retrieve my decompressed body from the vacuum?

Or is there something else they're not telling me?

Hooker

Tell you what,.... we'll cross that bridge when we get there.

in the mean time.... "Let's put it on, the last suit you'll ever wear"

Now you're really confusing me!! There's a bridge at the end of the earth??? I hope it's beyond NTSB certification.

And I already wore the last suit I'll ever wear, when I retired. And if I have to wear another suit to my funeral, I ain't going.

Hooker

And if I have to wear another suit to my funeral

well, the suit is black... .

sorry for the diversion but this thread was off its trolley a while ago....

Off its trolley...

On the original post!!

Like on this game I play, once you fly off the map, there be beasties, you don't show up to other players, and you are flying over what appears to be water that goes on endlessly. Walk away too long, and you won't have enough fuel to turn around and make landfall.

I have yet to fly off the map, and re-enter from the other side, but I suppose a positional overflow bit might just do that. IF we are talking flat earth, we must also be talking simulation as per The Matrix, right?

You mean, this game ?

Don't forget to wear your tin hat while playing.

I'm leaving now. This thread has become insulting to intelligent people.

Always a pleasure to hear your thoughts, English Rose!

Do svidaniya

You mean to tell me this was suppose to be a serious thread... lol

Then since it only is an insult to intelligent people, you should stick around.

Come on, Lyn, you know you have to chuckle at that one.

Come on, Lyn, you know you have to chuckle at that one.

I did...

If the Earth were not rotating, how would one explain the Coriolis Effect when water drains from a cast iron bath that is not broken?

The explanation would have to be Cavalier.... and the one (only?) consistently reliable quality of Cavalier is it doesn't work.
