Do you know? If gravity in the world were to disappear for five seconds, everything on our planet would cease to exist. What is Gravitational Force?
Gravity is a necessary condition for a planet to survive, and losing it, even for a few seconds, can have a devastating impact on our lives. Gravity is also known as gravity, and gravity is a force exerted by the Earth on everything around it, from the smallest pebble to the tallest skyscraper. Anything has to fall on the ground, although astronauts who have seen space movies are floating.
The absence of gravity seems to be an interesting situation, it disappears so that it can fly freely. However, if you fully understand the importance of gravity, even if it is only for five seconds, you probably don't want that to happen.
To understand the importance of this gravity, what happens after that, if we can turn it off? In this case, the first thing that will happen, everything will change immediately, not only you, but also vehicles, garbage, animals, etc., even trees, street lights, buildings, and other things that are placed deep underground will float and roll wildly in the air. The Earth then rotates faster along its orbit.
Therefore, the place most affected by gravity is on the Earth's equator, where there will be winds that are six times stronger than before, which means that in just five seconds, you can be blown kilometers away, and the great flood that will follow.
Without gravity, the Earth's atmosphere would disappear because all the gas would float into outer space, which means there would be a sudden change in air pressure that would immediately break the eardrums of every living thing on Earth. Not only that, but without an atmosphere, there would be no oxygen on Earth, which can be deadly. There is no oxygen on the earth for five seconds, and I silently said it in the last two issues, oh, if you want to know, you can go and see it.
Without this gravity, the Earth's core pressure would cause the planet to expand, which would mean large and massive volcanic eruptions. Since gravity plays a dominant role in the Earth's orbit around the Sun, without gravity it would begin to drift in space at a speed of 30 kilometers per second, which would be the end of the world for us. So don't take gravity for granted, it's crucial to always keep your feet on the ground.
-
If that happens, the whole world will be in chaos, but it's unlikely.
-
Then all the buildings on Earth will disappear, and humans will cease to exist, which may cause the Earth to fall as well.
-
Our planet will definitely fall faster, and all the oceans will have big waves that will definitely submerge the land.
-
All objects on Earth will fly into the air at the speed of sound, near the speed of sound or supersonic speed along the tangent of the diameter of different sections of the Earth (north-south axial cross-section)! After that, because there is only the velocity of the beginning and no continuous acceleration, the object cannot fly out of the atmosphere, and all objects, including people, will fall to the earth in free fall, which will be an unimaginable disaster!
Why? Because the earth is rotating all the time, and the speed is absolutely not slow, we can simply calculate: the length of the earth's equator is 40192km, and the time it takes for the earth to rotate is 24h.
40192 24, the speed of sound is 340m s, so everything on Earth, including us humans, is flying at supersonic speed all the time,It's just that we don't feel it ourselves. Based on our experience of taking a bus or driving a car with a sudden brakeOnce the car in high-speed motion stops suddenly, the people inside will immediately be slapped on the seat by the huge inertia, and they will either die or be injured.
But after the earth suddenly stops, you will not be photographed in the car, because the earth has no top, so you will immediately experience the feeling of supersonic speed of human flesh, everything on the earth will be thrown into the air, and because it only stops for a second, and then the earth will resume its rotation and then it will be severely ravaged by inertia.
We need to understand a few parameters: the structure of the earth is divided into the inner core, the outer core, the mantle and the earth's crust and other multilayers, the diameter of the earth is 12,740 kilometers, the rotation is 24 hours, and the linear velocity of the equator is about 463 meters and seconds. According to the law of conservation of angular momentum, the energy of this rotation cannot be released, and the multiple layered Earth's mantle and outer and inner cores will continue to rotate, which will lead to an interesting result
Stratification may occur between the Earth's crust and mantle, which may be the location of the asthenosphereWith this as the boundary, the inner core still maintains its rotation, and gradually stops when it is outside and inside, and the movement stress of the rock formation in the inner and outer crustal layers accumulates to the limit after the rotation stops!
Everyone should know what the consequences of this stress accumulation to the limit will be, for example, most of the modern major plates are caused by plate edges or internal fractures, so it is difficult to estimate how much of the stress accumulation of the major plates in the world exceeds the limit! Maybe twelve? Or higher?
It was a devastating catastrophe in which human civilization was wiped out in an instant, the entire earth's ecosystem was shattered, and the ground was unrecognizable. Here's how it looks:
Because the earth suddenly stopped rotating, everything on the surface of the earth, including the teacup in our hands and the television set in front of usAnd the building you live in will maintain its original speed, maintaining the trend of eastward movement. How fast is that?
Near the Earth's equator, the rotation rate is 465 m s, which is faster than the speed of sound. If we were traveling in the tropics near the equator, when the Earth suddenly stopped rotating, that speed would be our speed, and we and everything around us would be flying forward and upwards at 465 m s.
-
I think this catastrophe is devastating, because if the Earth comes to a standstill, its inertial acceleration is very large, and it will throw us humans far away in space, like a speck of dust.
-
If the earth suddenly stops rotating for one second, the catastrophe that human beings will encounter may be beyond our imagination, and it may bring about a devastating disaster, because the earth's rotation speed is about 470 meters per second, then we have inertia on the earth, and if it suddenly stands still, we may be thrown into pulp because of inertia, and everything else is the same.
-
There will be no particularly big disasters, because one second is very short, it will not affect life, it will not affect the normal operation of life, it will not affect the crops.
-
The subject is talking about ifs, then I'll use the if-like fantasy way.
If that's the case, the earthlings will have to think about speeding up the space migration.
Because of gravity, the earth's water, air and other substances can exist on the earth safely, and the moon can revolve around it. Without the gravitational pull of the earth, each of us, and everything on the earth, will become one fluid after another as we travel in space today. Because the Moon is closest to the Earth, most of the Earth's material begins to be attracted to the Moon, and even collides with the Moon many times, becoming a part of the Moon, or a satellite.
At this time, the Moon may no longer need to revolve around the Earth, but directly revolve around the Sun, and at the same time rotate. The Moon replaces the Earth as a planet in the solar system. A few years later, the Moon became a new home for earthlings, flora and fauna.
Back to reality, it's a question that will never hold! However, this question needs to be put in a different way to be true! For example:
What will happen to humans when the atmosphere disappears? What will happen to humanity when the earth disappears one day? Or rather:
When the solar system disappeared, did humans still exist?
Secondly, I would like to say why the "hypothetical disappearance of the Earth's gravity" is a never-tenable question!
We know that in the universe, there is a law of the immortality of matter and the conservation of energy! Since matter is immortal, and only the concrete form of matter is destroyed, then for the universe, there will always be matter in it, there will always be mass, and if there is mass, there must be energy! Gravity is another form of existence of matter energy!
Between matter, gravity is everywhere! It's just that the size is different!
The Earth can disappear, the Sun can disappear, galaxies can disappear, but gravity as an energetic state of matter will never disappear!
Finally, I would like to say that the universe will always have mass, energy, and forever"Infinitely extended"And the way of "this present tense" exists!In the face of the universe and the future, the question that is more worthy of our consideration is: why does matter not perish?
Why is energy conserved? What unites a complete universe?
-
It should be like they are all floating in the air, and everything is floating in the air, and it is very inconvenient for everyone to do anything without gravity.
-
Needless to say, everything on the surface of the earth gradually levitates. First of all, the human walking on the ground, after the earth's gravity disappears, will obviously feel "light as a swallow", and then fly unconsciously.
-
If the earth is weightless, then we will definitely float upward, we will feel that our body has become very light, we need to jump when walking, or gently point with our toes, and after a long time, there will also be bones become very fragile, bone calcium loss is serious, and our body's circulatory system will gradually collapse, resulting in lack of oxygen, suffocation, dizziness.
-
If the earth starts to lose weight, we will all become birds and float straight into the sky.
-
Introduction: If the earth starts to become weightless, our lives will definitely be greatly affected. If you are weightless, it may affect the body's immune system, causing people to experience some symptoms of hearing impairment, low blood pressure, arrhythmias, loss of bone calcification, and dehydration.
And to know that there is no profit in the words of us. The heart may also be affected, slowly declining, and the eyes may also have eye diseases, so we must protect our existing living environment to avoid excessive damage affecting our lives.
It is important to know that during weightlessness, the body's hydrostatic pressure loses blood and body fluids, and there is no way to sink or circulate as before, which may lead to edema, head swelling, neck varicose veins and other silver services, etc., and there may also be reflex polyuria fluid reduction Body fluids decrease, which may cause arrhythmia, myocardial hypoxia and myocardial degenerative changes. If we are really in a state of weightlessness, it is estimated that it will not be long before we lose our lives. Now those astronauts on the moon, they are actually in a state of weightlessness, and long-term survival in such an environment will seriously affect their physical health.
If we are in a state of weightlessness, there may also be a disorder of motor coordination, because the disappearance of gravity will seriously affect people's spatial positioning and motor control ability. In a state of weightlessness, the common digestive tract reaction of the human body is an increase in saliva secretion, stomach discomfort and even vomiting, but the function has been obviously disordered, and the ability of gastric epithelial cells to produce mucin is also significantly reduced, and the protective effect of gastric mucosa will be weakened. In weightlessness, it may also lead to a decrease in the motor, sensory and higher functions of the nervous system, as well as a significant decrease in some of the more complex visual functions in weightlessness.
-
If the earth is weightless, we may fall and lose our footing, and then everything in the world will slip and be broken, and this wonderful world will cease to exist. The world we live in will no longer exist.
-
We can't live normally, we may float in the air, there will be some changes in the lack of plants and creatures, there may be some extreme weather on the earth, and there will be no life.
-
We will be greatly affected, it will seriously affect our daily life, and it will also affect our own behavior and habits. It will also lead to an imbalance in the ecology and some extreme weather.
-
Maybe the society will change, there will be a lot of natural disasters, affecting people's sleep quality, there will also be gravity loss, or there will be environmental problems, etc., the impact on us is still very big.
-
There is no way to go about a normal life, there is no way to go to the toilet, there is no way to eat, there is no way to take a bath, there is no way to travel, the muscles of the human body may relax, and the blood pressure may be adjusted.
-
If the earth is weightless, we will not be able to survive on the earth, and human beings will slowly die because of weightlessness.
The second is that it will also make everything above the earth float, and finally we will no longer have to fear falling and hurting ourselves, but at the same time, we will face a weightless situation.
Finally, it is possible that all animals and plants will float up and then not survive.
We all live on a common planet, which is the earth, and if gravity disappears, the harm is very great. If there is no gravity, the Earth is like outer spaceVacuum state, then it willLoss of oxygenexists. All flora and fauna will not survive, and we know that each planet moves in outer space according to its own specific orbit, and they have a mutual attraction to each other. >>>More
The earth's magnetic field is called the "earth's umbrella", if the earth's magnetic field is completely lost, then the whole earth will be paralyzed, and those high-speed high-energy particles with electric charges in the universe will directly reach the ground, instead of gathering at the high altitude of the north and south magnetic poles when there is a magnetic field, which will cause devastating damage to all living beings except the deep seabed.
Seventy-one percent of the planet is covered by oceans.
The role of the ocean on the earth is very important, and if there were no oceans and seawater, there would be no earth now, and there would be no various creatures on the earth now. If all the seawater on the earth disappears, all life on the earth will be extinct, and the earth will become a desolate place like Mars, which is what none of us want to see, so we must protect the earth and protect the ocean. >>>More
We often say that we are very small in front of the earth, but there are still people who do not believe that we humans can control the fate of the earth, in fact, just give a random example and you will understand how ridiculous this idea is. We know that the earth is constantly rotating, but have you ever wondered what would happen if the earth suddenly stopped for 1 second one day? Say it and you may not believe it. >>>More
If the earth is square, the sun will no longer shine and shine on the earth. Because the Earth is square, the Earth becomes a hexahedron, and it stingily concentrates light on one side, and the temperature of the ground rises rapidly. >>>More
