00:00Imagine this rockambolesque scenario.
00:02You are in the sky, at the beginning of an airplane,
00:04and suddenly, the world stops turning for 10 seconds.
00:08It's like if the time was fixed.
00:10First of all, let's talk about the physical experience.
00:14When the world stops turning,
00:16you feel a sudden absence of movement.
00:19The plane, which was in the air a few moments,
00:22stops.
00:24The mobility and the silence are surrealists.
00:27You could even feel a slight secousse or a décalage,
00:31because the device certainly will adapt its movement to this brutal change.
00:36If you look at the plane plane,
00:38you assist in an extraordinary spectacle.
00:41The clouds are immediately,
00:43like paint paint in the air.
00:46The sun is like the sun,
00:48and creates a light of another world.
00:50The landscapes,
00:52whether cities, mountains,
00:54or vast forests,
00:56become strangely fixed.
00:58A crowd of thoughts and feelings
01:00engulfed your mind during this suspend moment.
01:03First of all,
01:04you experience a feeling of fear and excitement
01:07face to the oddness of the situation.
01:09You are a witness of something
01:11that is the laws of nature,
01:13a temporary perturbation during the time.
01:16You could also feel a point of anxiety
01:19or anxiety
01:20that feeling of excitement.
01:22After all,
01:23you are in the command of an airplane,
01:25and everything just stops.
01:26The questions are in your mind.
01:29What is the cause?
01:30Is there a risk for the airplane
01:31or for people on the ground?
01:34When the world stops,
01:35imagine the effect that this event
01:37would have on everything
01:38around you.
01:39On the ground,
01:40people would also be afraid.
01:42The cars would stop abruptly
01:44on the roads,
01:45giving an impression
01:46of a film of science fiction.
01:48Imagine the expressions
01:49of the drivers and the drivers.
01:51In the big cities,
01:53the animated rues would be transformed
01:54into a inquiet picture.
01:56The activities,
01:57committed to the time,
01:59like the deliveries and public transports
02:00would also be affected,
02:03causing momentarily chaos
02:04while everyone tries to understand
02:06what just happened.
02:08The nature would even touch it.
02:10The trees of trees,
02:11which tremble and bruise
02:13without cesse,
02:14would stop suddenly.
02:15Even the waves of the ocean
02:16would be in full fracas,
02:18immobilized within their powerful movement.
02:20For the rest of the world,
02:22we can say without risk
02:23that this phenomenon
02:24would capture the attention
02:26general attention.
02:27The information organizations
02:28and the social networks
02:29would be envahi
02:31of reports,
02:32of videos
02:32and photos
02:33of this unique instant.
02:34The scientists
02:35and experts
02:36of the various domains
02:37would be forced to provide
02:38explanations,
02:40theories
02:40and suppositions.
02:42The filmmakers would make
02:44documentaries
02:45to explore the global impact
02:47of this mysterious phenomenon.
02:48But suppose
02:49after these 10 seconds,
02:51the world
02:51would be turning
02:52as soon as inattend
02:53as it was stopped.
02:55When the movement
02:56is established,
02:57you feel a
02:58explosion of acceleration.
03:00The plane
03:00takes its way
03:01to advance
03:01and you feel the gravity
03:03and the movement
03:04coming back to the normal.
03:05The landscape
03:06in contrebas
03:07are moving,
03:08a bit like a video
03:09in acceleration,
03:10passing to reverse.
03:12It is possible
03:13that your emotions
03:14change a new time.
03:15You could feel
03:16a mix of excitement,
03:18excitement,
03:19and curiosity.
03:20You just assist
03:21to an extraordinary
03:23of the nature
03:24You may ask
03:26some questions
03:26and you are impatient
03:27to know
03:28if someone else
03:29has experienced
03:30the same phenomenon.
03:31Imagine your conversations
03:32with friends
03:33and experts,
03:34the theories
03:35and the tentative
03:36to pierce
03:37the mystery
03:37of this singular event.
03:39Of course,
03:41the hypotheses
03:41on the cause
03:42of the temporary
03:42rotation of the world
03:44would be infinite.
03:45Is it a scientific anomaly
03:47or a cosmic event
03:49or even a failure
03:50in the tissue of reality?
03:53In the next scenario,
03:55you will not have this chance.
03:56You are trying
03:57to voltage
03:58at 3000 meters
03:58of altitude,
04:00taking advantage of the view
04:01from your fellow plane
04:02when a shock
04:04of a power
04:04inouye
04:05is spread in the air.
04:06It is like
04:07a bang sonic
04:08who would be able
04:09to lift the ground
04:09to the ground
04:10higher than the sound.
04:12Like you are
04:13at 3000 meters
04:14above the surface,
04:15this shock
04:16will hit you
04:17like a ball
04:18in less than an eye.
04:19You will only have
04:20two seconds.
04:22At this moment,
04:23prepare you
04:24to face
04:24big turbulence.
04:26You will be
04:26in your vehicle
04:28like a bullflipper.
04:30A real tour
04:31in the mountains
04:32monstrueous
04:33which defies
04:33the gravity
04:34if we suppose
04:36that the air
04:36will be mobilized
04:37along the earth,
04:39attach your
04:40belt
04:40because you will
04:41cross the
04:42atmosphere
04:42of a speed
04:43of about 1600 km
04:45at an hour.
04:46Your poor plane
04:47will not support this
04:48speed
04:49and it will be reduced
04:51in a bubble
04:51before you can say
04:53oh no.
04:55We are talking about
04:57an hour
04:57instant
04:57like if you
04:58would have
04:59a brick wall
05:00at full speed.
05:01L'array
05:02of the world
05:02means that
05:03all those who
05:03are located,
05:04including you,
05:05continue to move
05:06to the same speed.
05:07Yes, it is true.
05:08You would be
05:09in a chaotic
05:10chaotic
05:10like a dog
05:11in a hurricane
05:12where you are.
05:13Even if you
05:14fly in your small
05:16plane,
05:16in a metro
05:18or exploring
05:19the big space
05:20in a calm walk
05:22in a calm walk.
05:22The sad reality
05:23is that your destiny
05:25would be
05:25and that it would not
05:26be able to catch you.
05:28Now we have
05:29the power of the
05:30rotation of the Earth.
05:32The rotation
05:33of our planet
05:33is bearing
05:34an astronomical amount
05:35of energy,
05:36of energy stock.
05:37If the rotation
05:38of our globe
05:39had to stop suddenly,
05:41all this energy
05:42would need
05:43to be evacuated.
05:44And the most probable
05:45is that it would be
05:46manifest in a form
05:47of heat.
05:48It's like if,
05:48abruptly,
05:49we would have
05:50an immense
05:51vacuum of energy
05:52thermal energy.
05:53Imagine the front
05:55the most colossal
05:56that you could imagine.
05:57Without airbags
05:58to attenuate
05:59the shock.
06:00A total catastrophe
06:01with epic proportions.
06:04Everything,
06:05and I say
06:05everything,
06:05everything goes
06:06like a porcelain
06:07In a word,
06:09the chaos
06:09would be
06:09apart from the first place.
06:14Now,
06:15we start to reopen
06:15all this from the beginning.
06:17How are they going?
06:18Four essential forces
06:19are going to allow
06:20to have an船
06:21to rise in the ciel.
06:22First,
06:23it's the psi.
06:24This force is responsible
06:26to pushing the船
06:27up to the high,
06:27which is the way
06:28which is the direction
06:29around the air
06:30that generates the port.
06:31The shape of the
06:32arm does likewise
06:33This is also a role in contributing to reinforce this force.
06:38Then there is the weight.
06:40It's the force that attracts the plane towards the Earth,
06:43like gravity in action.
06:45To maintain balance,
06:46the planes are built in order to distribute their weight uniformly from the front to the rear.
06:51Then there is the push.
06:53It's this force that pushes the plane towards the front.
06:55All this thanks to the motors,
06:57which provide the necessary impulse.
06:59It can be an ellis or a reaction motor.
07:03As long as the air moves on the plane,
07:05the plane continues to advance.
07:09Finally, there is the train.
07:10You may have probably experienced the experience in walking face to a strong wind.
07:15The train is the force that slows the plane.
07:17These devices are designed to minimize the train
07:20in allowing the air to pass around them.
07:23A plane can fly when these four forces act harmoniously.
07:26And of course, we need the pilots.
07:29In our scenario,
07:31this is different than you.
07:32This led me to ask how the rotation of the Earth affects the speed of an airplane.
07:37It's obvious that it doesn't affect anything.
07:39Imagine you at board of a train.
07:41If you jump in the air while the train is running,
07:45you think you get a few meters of your initial place
07:48simply because the train,
07:50he, continues to advance?
07:52And no, this will not happen.
07:54It's the same for the planes.
07:56It's the same for the planes.
07:57They move in the air following the rotation of the Earth
07:59and their speed is not affected by this rotation.
08:04But here's the hic.
08:06At different altitudes,
08:07the wind can influence the speed of an airplane.
08:10Suppose you go from Paris to Los Angeles.
08:12In terms of the wind,
08:14your time of flight to go and return
08:15could differ in a considerable way.
08:18In summary,
08:19the rotation of the Earth
08:20does not make the planes out of their trajectory.
08:22But the wind can influence their speed.
08:24it's...
08:25you, the whole-
