Re: In the news
I routinely espouse the philosophy that the Earth is flat. I do so regularly on Facebook. In fact, I always take that position whenever the question comes up. I mean, it's obvious, isn't it?
The thing I really do - genuinely - admire about the idea of arguing that the Earth is flat, is that it is a fantastic intellectual exercise. It requires huge mental agility and imagination, in the face of everything stacked against the idea, to keep arguing that the Earth is, indeed, flat. It's not good enough to repeatedly say so; one should be able to reason, preferably with supporting evidence, that the Earth is flat.
Try it. It's a genuine challenge.

See? That's the trouble. That's why so many people believe all this fake news that the Earth is round, when it's clear just by looking that it's flat.Nanohedron wrote:Gaah. Too lazy.

Re: In the news
Oh, it is, all right. Cartoon-style witty, just like the rest of the whole bombastic show. It's hilarious, really, and I do love it. But then I'd have to give him credit for having the wit it takes for such bizarre theater rather than for being a full-on loon willing to risk his life. And it's because of that last bit that until I see enough evidence to the contrary, TBH I'm just not quite ready to do that yet. I'm never surprised at how crazy people can be, although I admit this one's capital-S Special, so you do make a case.

I really do want him to launch. Not that he should get hurt, of course, but just to see him properly put the cherry on top. I picture him popping into the sky like a champagne cork, and probably staying up just as long. Hope the joyous moment goes to YouTube. Maybe I'll send him bouquets with cards signed, "From an Adoring Round-Earther Fan."
You say he's done publicity stuff like this before, s1m0n. Do you know this for sure?

Re: In the news
Okay, Ben, try this one on for size: Boffins in the news say our equator has shrunk. True story. We're nowhere even near to looking like an 8, of course, but apparently there will still be a marked increase in tectonic disturbances like earthquakes and volcanic activity, especially in Equatorial zones (around the world, I dare say), because of it.
Plenty of fodder, I should think, to gyrate your mentations over. How say you?

One way to get an absolutely flat reference surface is to use water. If you let it sit quietly long enough, it will be flat and level.

Re: In the news
Scientists at the Greenwich Observatory in London used this method - only with a pool of mercury* rather than water - as their horizon when calculating the location of the prime meridian. There's a monument there today, with an iron (I think) line inlaid in the pavement showing the location. Interestingly, it's off by 100 yards from what present day visitor's GPSs show as 0° long. The explanation is that back in the 19th C when the experiment was being conducted, the presence nearby of a large mass was just enough to alter gravity locally and throw the instrument off, slightly.chas wrote:On a small scale, of course, you're absolutely right.benhall.1 wrote:I routinely espouse the philosophy that the Earth is flat.

I must admit, I don't understand this at all. As the article points out, the position of the Meridian line is entirely arbitrary, so how can it possibly be in the wrong place?

Re: In the news
That one's easy. The equator is, of course, halfway between the centre of the disc (what rounders call "The North Pole") and the ice wall. I suppose it may well be shrinking. Now, that could be the whole disc shrinking (and who doesn't think the world is getting smaller these days?) or possibly a sort of crinkle in the disc. That would almost certainly cause disturbances such as earthquakes etc.Nanohedron wrote:Okay, Ben, try this one on for size: Boffins in the news say our equator has shrunk. True story.

If you measure almost any body of water, there will of course, be curvature. Measuring a pool of water 300mm across is tricky. It's a bit small, really. And the edges will either curve upwards or, depending on what is holding the liquid, possibly downwards if the water is sitting on a surface - in the form of a drop, for instance.chas wrote:On a small scale, of course, you're absolutely right.benhall.1 wrote:I routinely espouse the philosophy that the Earth is flat.

But proper scientific people have proved that water is actually flat. You've heard of The Bedford Level Experiment have you?
(I must admit, I'm not the best at this sort of argument yet. I probably need to practise more. )

Re: In the news
The prime meridian was defined mathematically (or astronomically) a century before it was located physically. The earliest definition was about navigation, so it provided ships with a way to fix their position dependant on the location of various stars, relative to the horizon at various times. At sea, navigators use a sextant to record the height of the sun, or of a number of reference stars, above the horizon at a pre-determined time (noon, for the sun. Or midnight for the stars). From this, and from pre-determined information about the sun and star's positions relative to the earth at any given place and time, it is possible to determine place, if you know angle and time. Or time, if you know angle and place.benhall.1 wrote: I must admit, I don't understand this at all. As the article points out, the position of the Meridian line is entirely arbitrary, so how can it possibly be in the wrong place? It could be anywhere. :-?
The Victorian boffins wanted to calculate place, using the known positions of a handful of reference stars. Stars are smaller, visually, and much farther away than the sun, so any sighting of them will be much more accurate. At sea, a navigator uses a sextant, measuring the angle between the horizon and the sun at noon. That works, although the accuracy isn't perfect. The victorians wanted better.
So they set up a super-sextant that would record the angle between the horizon and several stars (polaris, etc). Only that meant they had to do it at night, and not at sea, so no horizon would be available. The pool of mercury was an attempt to create a false horizon. The Victorian boffins' super sextant worked better than any previous attempt, but it wasn't perfect.
And now there was no doubt that the trees were really moving - moving in and out through one another as if in a complicated country dance. ('And I suppose,' thought Lucy, 'when trees dance, it must be a very, very country dance indeed.')

Re: In the news
No, through a theodolite the bright stars used in determining location are visible on a clear day. They are much brighter than the moon, and you can see that in the daytime. It helps to know roughly where they will be, so roughly where you are.s1m0n wrote:Only that meant they had to do it at night
I think what they wanted was the angle between the horizontal and stars. The horizon is below the horizontal but don't ask Ben why that is so.s1m0n wrote: the angle between the horizon and several stars (polaris, etc).

Re: In the news
Let's try another one, Ben. Here's an artist's interpretation of the neighborhood:
Here we see our brave little (flat) planet orbited, counter-Copernicanwise, by the Sun and Moon. Since evidence suggests that stars and planetary masses all share a more or less common form, why then would the Sun and Moon be spherical, as they clearly are here? One would think they should be flat, too. If it's artist's oversight, I'll bite my tongue and play along by defending the inconsistency. Tell me how I do:
Of course other heavenly bodies are spherical. Only a fool would dispute that, and the evidence rests on the fact that they're unpopulated: In the end, the only thing you can do on a sphere is slide off of it (which should be even more evidence that the 1969 Moon "landing" is a hoax). Only a flat surface can support life, in the most physical sense of the word. It might well be that Earth, and Earth alone, is flat in aaaaaalll the universe. An anomaly. A frisbee among the balls. A lonely little petunia in an onion patch. But we might not be all that unique; after all, the boffins (if they are to be believed) routinely announce it when they detect Earth-like planets. But what it really means, then, is that they've found more flat ones, and they're just not telling us that part of it. Typical.
Okay, how was that? Not as scientific as you, sure, but I thought the whiff of paranoia at the end was a nice touch. Baby steps, right?
On a side note, it seems to me that Flatters should probably ditch trying to account for the Equator any more; that's the stuff hernias are made of. I wouldn't even begin to try time zones. No, wait. I might even get there.
Anyway, while you're at it, if you'd also like to explain our other planets' places and roles in our solar system (strictly as a bonus, of course), we'd be most indebted.
