[Misc] Do you believe the Earth is flat?

Agree. It's a zero chance in the same way that there is zero chance that you or I won't die.
On that happy thought, I'll leave his thread and go find a more cheerful mad-as-a-box-of-frogs theory!

If you fly around in a circle, you will return to the same point.
You're actually a lot less likely to die than the world not being "round" imho.
Eternal life can't be that far into the future.
Agree with @Greg Bobkin that nothing is entirely certain. For all we know or don't know the world can be some sort of 2D chip installed into the head of a horse on Mars and the whole thing is just some optical illusion. Technically it is also not quite round but rather... some other geometric shape I've forgotten about.

Surely, the only way that you could personally say with 100% certainty that the earth is a globe, is by you personally observing it from several thousand miles away, otherwise you are just relying on what others have told you or filmed or photographed. You may be an spaceman so apologies if you have actually observed this.
Correct. Gravity from the moon and Sun makes the planet ‘fat’ at the equator.
Far more interesting than flat earth theory is how flat earth grifters convince the thickest c***s of their toddler science and then make a lot of money. They should not have any airtime. They are conmen in the mould of Farage.

Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jellyfish[2][3] found worldwide in temperate to tropic waters. It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual. Others include the jellyfish Laodicea undulata[4] and species of the genus Aurelia.[5]
Like most other hydrozoans, T. dohrnii begin their lives as tiny, free-swimming larvae known as planulae. As a planula settles down, it gives rise to a colony of polyps that are attached to the sea floor. All the polyps and jellyfish arising from a single planula are genetically identical clones.[6] The polyps form into an extensively branched form, which is not commonly seen in most jellyfish. Jellyfish, also known as medusae, then bud off these polyps and continue their life in a free-swimming form, eventually becoming sexually mature. When sexually mature, they have been known to prey on other jellyfish species at a rapid pace. If the T. dohrnii jellyfish is exposed to environmental stress, physical assault, or is sick or old, it can revert to the polyp stage, forming a new polyp colony.[7] It does this through the cell development process of transdifferentiation, which alters the differentiated state of the cells and transforms them into new types of cells.
Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal,[3][8] although in practice individuals can still die. In nature, most Turritopsis dohrnii are likely to succumb to predation or disease in the medusa stage without reverting to the polyp form.[9]
The capability of biological immortality with no maximum lifespan makes T. dohrnii an important target of basic biological aging and pharmaceutical research.[10]

I have one for you.
The probability of meeting an Arsenal fan who doesn't bang on about that red card.
YEah but . . . . I can drive my car at say, Goodwood, and end up where I started. Not only is it flat, its straight, in a cosmic loop!

No, you can observe lunar eclipses from all over the world, and always see a circular shadow, therefore the earth is spherical.
You can navigate the surface of the earth and prove to yourself that it is a globe.
You can observe the sun, its rise and fall, and the changes to that over the year and from the Poles to the equator.
There must be dozens of ways to prove to yourself that the earth is spherical without getting off planet.

How do you know it isnt cigar shaped though?

The same way I know it isn't sausage shaped.

A shadow is two dimensional so will not demonstrate that the earth is a globe.
As stated previously, if you travel in a massive circle on a disc you will return to the same point.
Observing the sun and its movements does not in itself prove the shape of the earth. Why couldn't the sun rise and fall over a disc.
As indeed, plenty of ancient philosophers did quite successfully.
Weirdly, the idea that the world is flat has only been even vaguely popular after we left the planet.

OK, that's fine
Ironically then, you must believe that there's 0 chance there's an event that has 0 probability.

Yes/no/maybe. I got confused just reading that.Ironically then, you must believe that there's 0 chance there's an event that has 0 probability.
