Coventry would be cheaper.

WOW!!

look at all the fake i found here ... https://www.bas.ac.uk/

it really must be something they are trying to hide if they go to all this trouble to fake it, right folks?

how dare you besmirch such a fine city ?

It is both flat and 'round', depending on the perspective (and traveling speed) of the observer.

That's a very good video, with a lot of well-chosen and informative images. It's just a pity the guy feels obliged to adopt that deeply annoying "mad boffin" persona.

(People should not be put off by the title either. He merely points out that the earth would indeed look flat to a muon, or to anything traveling close to the speed of light.)

It's a bit more complicated - awesome.

Whilst gravity tends to look a bit like this


It also varies, due to distance, a bit like this

So you feel strangely lighter as you get to the edge*. Simultaneously feeling both lighter and...more disturbed.

But there seems to be a complication. Gravity (apparently) doesn't always point to the centre of the cube!

It varies a bit like this, so these lighter areas give the adventurer a weirdness break

So... I think this is where folk would live (or maybe where you would find the flat earthers), on these islands of least perturbation, and perhaps where all life would take a greater hold. Unless they built a floating city in the middle, where all the water would be.

But, as pointed out in one of the articles below

If you were accustomed to living on a spherical earth (as we are), I believe you would feel like the entire face of the cube you were standing on were sloped at a fixed angle, and this angle would depend on where on the face you were standing.

What interests me is how would you feel had you evolved on the cube? I find myself unable to imagine. It's almost like a mind calming exercise... staring into a void.

The exact same article published by gizmodo and strangely easier to read:

And the (aptly named?) complication:
https://possiblywrong.wordpress.com/201 ... re-a-cube/

* no, they don't cancel out and give a flat result. A pity.

(Seriously, I'm trying to find support for the flat earthers of cube land. It's here somewhere - I'm sure of it.)

On Antarctica’s coast, where our stations are located, there are usually a couple of weeks in mid-winter (around 21 June) when the sun does not rise, and a couple of weeks in summer around Christmas when there is 24-hour sunlight.

http://www.antarctica.gov.au/about-anta ... ight-hours

Sorry, dude.

Since the Amundsen–Scott Station is located at the South Pole, it is at the only place on the land surface of the Earth where the sun is continuously up for six months and then continuously down for six months. (The only other such place is at the North Pole, on the sea ice in the middle of the Arctic Ocean.) Thus, during each year, this station experiences one extremely long "day" and one extremely long "night". During the six-month "day", the angle of elevation of the Sun above the horizon varies continuously. The sun rises on the September equinox, reaches its maximum angle above thehttp://www.rigorousintuition.ca/board2/viewtop ... =8&t=39998 horizon on the summer solstice in the Southern Hemisphere, around December 20, and sets on the March equinox.

I just showed you two videos clearly doctored that are used as 'official' proof of the Antarctica midnight sun. So you coming back with an even less evidence doesnt really get us anywhere since Ive demonstrated that this issue is tainted.

Yes, you are correct about this "midnight sun". But as you can see, only half the time.

Interesting stuff, tazmic. But:

The diagram you cite doesn't support that assertion:

Edit: Also - how do you explain that you can clearly see the curve of the Earth if you're standing on a beach looking out at the ocean (no planes or windows involved)?

Because objects have density. It is the most simple and obvcious explanation for why we do not float off into space. How can you rationalize that an object (the earth) moving 1000 mph doesnt hurl off all atop it via centrifugal force?

Of course we have density, that still doesn't explain why we stick to the ground. Why do we fall back down again if we jump? What force pulls us back?

I assure you that you havent actually seen the curvature and if you were to create a massive level to judge against the ocean horizon you would clearly see there is no curve.

And I can assure you that you're wrong. Have you even been out in the ocean (as in: where you can't see land in any direction)? I have, repeatedly, and I can tell you with 100% certainty that the horizon is not flat. It's curved. Seriously, if you're near the coast just go down to the beach and look for yourself.

Edit: You do realize that the modern Flat Earth theory was conceived as a joke, right? What next? Pastafarian extremists?

Why do we fall when we jump? Because we are denser than the supporting medium. Why would you assume there is a force pulling us down when it is accurate to say that we are being pushed down by the weight of atmosphere above.

You still haven't explained why we fall down in the first place. Density does not equal weight.
What force gives us weight? And what force is making the atmosphere push us down? The atmosphere has much lower density than us, right? A pound of air weighs much less than a pound of flesh.

@mac The diagram in question just shows the variation in gravity's direction (from the centre), it's the second diagram showing the relative difference in strength. (My mistake I suppose, apart from mixing articles and derivations, was not to include a change of weight in my weirdness category....) Now that you bring it up I do find it strange the strength diagram doesn't even hint at this directional variation.

I've got a feeling that there's going to be a deep analysis of Bizarro World on The Secret Sun. I'm off to look

He's not dumb, he's convinced.

That is uncalled for. I think it is why the forum has a lot more readers than posters. People fear ridicule.

A succinct summary of horizon issues for those still confused about the law of perspective.

You have to take into consideration the Coriolis Effect. Reason being is at long distances the round Earth has spun beneath your bullet. While I hate all things military, this is a factor that must be used if you're going to hit the target.

Snipers dont actually take in to account the spin/coriolis just a fun meme to believe.

Yes they do for distances over ~1000 yards.

@Maco144

There is a really simple counterexample to the Flat Earth theory.

There are lots of people who fly between Jo'burg and Perth, Australia. I know people who have.

Yeah a lot of attacks against me by people sitting on the sidelines not even choosing to participate intelligently. It's exactly what I expected when I made my original comment about the old guard not having any rigorous integrity when it comes to this issue.
