Imaginez que vous êtes dans un avion, survolant le ciel, et que soudainement la Terre cesse de tourner. Incroyable, non ? Eh bien, si cela arrivait, les choses deviendraient assez chaotiques. L'air, qui se déplace avec la rotation de la Terre, continuerait à souffler à plus de 1 000 miles par heure près de l'équateur. Cela signifie que votre avion serait frappé par des vents fous, rendant presque impossible son contrôle. Au sol, ces vents causeraient d'énormes destructions, comme un ouragan survitaminé. Mais en l'air, même si l'avion restait intact, la trajectoire de vol et les systèmes de navigation deviendraient incontrôlables, car tout dépend de la rotation de la Terre. Donc, même si c'est une expérience de pensée amusante, espérons que la Terre continue à tourner—c’est beaucoup plus sûr ainsi ! 🌍✈️ Animation créée par Sympa.

FunTranscript
00:00Imagine this rocambolesque scenario. You are in the sky, at the command of a plane, and all of a sudden, the world stops spinning for 10 seconds.
00:08It's as if time was frozen. First of all, let's talk about the physical experience.
00:14When the world stops spinning, you feel a sudden absence of movement.
00:19The plane, which was rising in the air a few moments ago, stops.
00:25The immobility and silence are surreal.
00:28You could even feel a slight shake or a shift, because the plane will certainly try to adapt its momentum to this brutal change.
00:36If you look through the wings of the plane, you will witness an extraordinary spectacle.
00:41The clouds freeze immediately, like paint stains suspended in the air.
00:46The sun is like planted in the sky and projects a glow from another world.
00:51The landscapes below, whether they are cities, mountains or vast forests, become strangely fixed.
00:58A crowd of thoughts and feelings invade your mind during this suspended moment.
01:04First of all, you experience a feeling of fear and amazement at the strangeness of the situation.
01:09You are a witness to something that defies the laws of nature, a temporary disruption of the course of time.
01:17You could also feel a point of anxiety or worry mixed with this feeling of wonder.
01:22After all, you are in control of a plane and everything has just stopped abruptly.
01:27Questions arise in your mind.
01:29What is the cause? Is there a risk for the plane or for the people on the ground?
01:34As the world stops, imagine the effect this event would have on everyone around you.
01:39On the ground, people would freeze too.
01:42Cars would stop abruptly on the roads, giving the impression of a sci-fi movie.
01:47Imagine the expressions of pedestrians and drivers.
01:51In big cities, animated streets would turn into a disturbing picture.
01:56Activities subject to time constraints, such as deliveries and public transport, would also be affected,
02:02causing chaos while everyone tries to understand what has just happened.
02:09Nature itself would be affected.
02:11The leaves of the trees, which tremble and rattle non-stop, would stop suddenly.
02:15Even the waves of the ocean would freeze in a fracas, immobilized in the midst of their powerful movements.
02:21As for the rest of the world, we can say without the risk of being wrong that this phenomenon would captivate general attention.
02:27Information organs and social media platforms would be flooded with reports, videos and photos of this unique moment.
02:35Scientists and experts from various fields would rush to provide explanations, theories and suppositions.
02:43Filmmakers would make documentaries to explore the global impact of this mysterious phenomenon.
02:49But let's suppose that after these 10 seconds, the world starts spinning again in such an unexpected way that it has stopped.
02:56When the movement is restored, you feel a shake of acceleration.
03:00The plane takes its momentum forward and you feel gravity and the movement return to normal.
03:06The landscapes in the background start to move again, a bit like an accelerated video played backwards.
03:13Your emotions may change again.
03:16You could feel a mixture of relief, excitement and curiosity.
03:21You have just witnessed an extraordinary upheaval of the natural order.
03:25You may be asking yourself questions and you can't wait to know if someone else has experienced the same phenomenon.
03:31Imagine your conversations with friends and experts, the theories exchanged and the attempts to unravel the mystery of this singular event.
03:40Of course, the hypotheses about the causes of the temporal stop of the rotation of the world would be endless.
03:46Is it a scientific anomaly, a cosmic event or even a flaw in the fabric of reality?
03:53In the following scenario, you won't have this chance.
03:57You are flying at 3,000 meters altitude, enjoying the view from your faithful plane,
04:03when a shock wave of an incredible power spreads in the air.
04:07It's like a sonic bang that rises from the ground at a speed higher than that of the sound itself.
04:12As you are 3,000 meters above the surface, this shock wave will hit you like a bullet in less than a blink of an eye.
04:19You will only have 2 seconds.
04:22At that moment, prepare to face great turbulence.
04:26You will be swept into the cockpit of your plane like a bullflipper.
04:30A real ride in monstrous Russian mountains that challenge the laws of gravity.
04:35If we assume that the air itself is moving along the Earth,
04:39fasten your seatbelt because you will cross the frozen atmosphere at a speed of about 1,600 km per hour.
04:47Your poor plane will not be able to withstand this crazy speed
04:50and it will be reduced to a boil before you can even say,
04:53Oh no!
04:56We are talking about an instantaneous stop, as if you were hitting a brick wall at full speed.
05:01The stop of the world means that everything that is there, including you, would continue to move at the same speed.
05:07Yes, it's true, you would be plunged into a chaotic frenzy like a chair in a hurricane, wherever you are.
05:14It doesn't matter if you were flying in your little plane, relaxing in a metro line,
05:19or exploring large spaces during a quiet hike.
05:23The sad reality is that your fate would be sealed and that it would soon catch up with you.
05:29Let's now talk about the power of Earth's rotation.
05:32The rotation of our planet carries an astronomical amount of energy, stored energy.
05:38If the rotation of our globe were to stop suddenly, all this stored energy would need to be evacuated.
05:44And most likely, it would manifest in the form of heat.
05:48It's as if, suddenly, we triggered a huge blaze of thermal energy.
05:54Imagine the most colossal frontal collision you can imagine.
05:58Without airbags to mitigate the shock.
06:01A total catastrophe in epic proportions.
06:04Everything, and I mean everything, would break like porcelain.
06:08In a word, chaos would reign without sharing.
06:14Well, let's go back to the beginning.
06:17How do planes fly?
06:19Four essential forces allow a plane to rise in the sky.
06:22First of all, there is the lift.
06:25This force is responsible for pushing the plane up.
06:28It is the way the air circulates around the wings that generates the lift.
06:32The shape of the wings also plays a role, contributing to strengthening this lifting force.
06:39Then there is the weight.
06:41It is the force that attracts the plane to the ground, like gravity in action.
06:45To maintain balance, planes are designed to distribute their weight uniformly from the front to the rear.
06:51Then there is the thrust.
06:53It is this force that propels the plane forward.
06:56All this thanks to the engines, which provide the necessary impulse.
07:00It can be a propeller or a jet engine.
07:03Anyway, as long as the air circulates on the wings, the plane continues to move forward.
07:09Finally, there is the drag.
07:11You have probably experienced it while walking in the wind.
07:15The drag is the force that slows down the plane.
07:18These devices are designed to minimize the drag, allowing the air to pass smoothly around them.
07:23A plane can fly when these four forces act harmoniously.
07:27And, of course, we need pilots.
07:30In our scenario, it is none other than you.
07:33This led me to wonder how the rotation of the earth affects the speed of a plane.
07:37It turns out that it does not affect it at all.
07:40Imagine yourself on board a train.
07:42If you jump in the air while the train is rolling,
07:45do you think you will land a few meters from your starting point,
07:49simply because the train, it, continues to move forward?
07:53And no, it will not happen.
07:55The same goes for planes.
07:57They move in the air following the rotation of the earth,
08:00and their speed is therefore not affected by this rotation.
08:05But here is the hiccup.
08:07At different altitudes, the wind can influence the speed of a plane.
08:10Let's say you were going from Paris to Los Angeles.
08:13Depending on the wind, your flight time on the way and on the way back could differ considerably.
08:18In short, the rotation of the earth does not make the planes deviate from their trajectory,
08:23but the wind can influence their speed.
