Fuck.

To begin with, it has been shown that the earth is not the center of the universe. In fact, it's totally stupid and self-centered to think so.

In fact, the Earth's curvature is not easy to see because of the colossal dimensions of our planet: the Earth's perimeter reaches 40,000 kilometers, or more than twenty million humans end to end! Only solution to see the curvature "live": go up, but by a lot. Airliners or high mountains are not enough – although curved windows or the aberrations of camera lenses sometimes seem to give it away in these circumstances. The Earth's curvature actually becomes really detectable at about twenty kilometers altitude and becomes absolutely inevitable from the international space station. But to take a complete photo of the ball, in a single shot, you have to move further away, towards the Moon for example – the first photo of this kind comes to us from the Apollo missions. It is not an experience within everyone's reach, alas (although with the rise of space tourism, perhaps it will be one day soon...).

Obviously, if the Earth is round, it is impossible to see very distant objects, they hide behind the curved horizon! On a flat world, on the contrary, things will certainly shrink as they move away, but they can never disappear. This is where the famous “boat that first disappears by its hull when leaving the port” comes into play, which you have certainly already heard. But, come on, admit it: you've never seen it with your eyes... Of course, it's not that easy to see it! You need good weather, clear air with little turbulence, and a good spotting scope or telescope: not accessible to everyone (again).

However, you can play a little with this horizon because it recedes when you go up: it is thus possible to see the Sun set twice, once at the bottom of a building, a second if you climb very quickly to the top of the building. here, which would not be possible on a flat Earth. Then, like the scholar Al-Biruni, we can notice that the further we move away from the earth's surface, the more the horizon is distant... but also lower!

And if you love shadows, watch the next lunar eclipses, when the Moon passes through the Earth's shadow and what shape does that shadow have, visible on the lunar face? A black area with a curved edge. So obviously, at first glance, it's just as compatible with a globe as a disc, except that... the lunar eclipse can take place in any configuration (at the zenith, low on the horizon, at a intermediate height) and the only shape that casts a round shadow from any angle is… a sphere.

Now I'm going to quote you this passage from the French press recounting the crossing of Antarctica by someone: "This new record for the crossing of Antarctica without assistance exceeds Mike Horn's previous performance by 206 km. An extension that the Australian explorer owes in particular to his ascent of the Argus Dome, considered the coldest place on the planet, temperatures can reach -100 degrees. He thus becomes the first man in history to climb the summit of the Dome, which rises to 4,093 m above sea level (a drop of 1,639 m).》If the earth is flat and Antarctica has a wall how to explain this? (Maybe not a good example but never mind)

Are you saying NASA lies to us for money? While its objective is exploration and spatial discovery? Why would they bother sending rockets and robots into space then? We give you a name, and it's conspiratorial.

Now, how to demonstrate gravity?

I'm offering you a simple experiment that will give you a formal and indisputable answer. You're jumping in the air. If you go up indefinitely, gravity doesn't exist, and if you go back to Earth, gravity does exist because that's its definition. If you stay suspended in the air without going down or up, then you'll have to come up with another theory.

Many platists still assert the "truths" without bothering too much about the process followed, the errors made, and the remaining uncertainties, but the most interesting thing about science, the way it progresses, is precisely by correcting our “natural” errors. Knowing about this adventure is as interesting as the result, and also protects against thinking too quickly. This also allows us to understand that, if skepticism is healthy, a little trust is just as necessary because we cannot repeat in a single life all the experiments of all the sciences, both "hard" and human, to re-obtain personally all the human knowledge acquired to date.

End of my message.

Cool

Ok,but...

In the next few years, the only thing that is a threat to humanity will be humanity itself.

Humanity can help each other, but anyway, are you sure humanity is a danger to itself?

I don't know.

But I hope not.

@LuneGelée I speak english UwU

Physics 😁

I hope not 😂

No, but only if it is well used.

Why ?

Let's take a robot with artificial intelligence.

If it is designed to do evil, it will do evil.

If it is designed to do good, it will do good.

But, are you going to tell me, an intelligence, even an artificial one, is always independent.

In this case, I will answer you that a robot, even with an artificial intelligence, is always in a way, "programmed", by its construction.

Obviously, I'm not really sure of the validity of my argument. If my argument is not valid, please correct me.
