Some people, called flat-earthers, truly believe in this retrograde idea.
Earth — the blue marble — is our spherical home. But what if Earth were flat? After all, some people, called flat-earthers, truly believe in this retrograde idea. How would everyday life function? Would it function at all? We explore how much of an oddball, or"oddslice" Earth would be if it were flat and whether there are any advantages to living on a strange disk with the sun and moon rotating overhead like a cosmic carousel.
Or perhaps on a flat-Earth, gravity would pull everything to the center of the disk — the North Pole. In that scenario, the farther away you are from the North Pole the more horizontal the gravitational tug toward the central point of the disk, according to James Davis , a geophysicist at Columbia University's Lamont-Doherty Earth Observatory. This would wreak havoc worldwide, but at least the world long jump record would be easily beaten .
3. Cloudy with a chance of sideways rain If gravity pulled toward the center of the planetary disk, which in this case is the North Pole, precipitation would also gravitate toward that spot. This is because precipitation falls to Earth due to gravity and will therefore fall toward the point of strongest gravitational pull.
We depend on Global Navigation Satellite Systems for anything from the GPS services on your phone, to travel information and supermarket just-in-time stock management to make sure produce arrives as fresh and as quickly as possible. And critically, emergency services use GPS to locate callers from their phone signal, the satellite communications could possibly save your life.
6. No more auroras and we'd all be roasted On spherical Earth, the swirling molten metal surrounding our iron core generates electric currents that in turn create our protective magnetic field which curves around the planet from one pole to the other, according to NASA . But on a flat Earth, without a solid core generating a magnetic field that protective layer — the magnetosphere — would cease to exist. And so would auroras.

Stability of the Antarctic Ice Sheet during the pre-industrial Holocene - Nature Reviews Earth & EnvironmentThe Antarctic Ice Sheet (AIS) underwent dramatic changes over the Holocene, impacting global sea levels. In this Review, Jones et al. discuss changes in this ice sheet during the pre-industrial Holocene. The drivers behind these past changes are explored, as well as their relevance for current and future changes in the AIS.
