Everything made by humans is an element of the earth, but why is the earth getting heavier and heavi

Human beings are bacteria, the ability to reproduce is too strong, from a few people in the ancient centuries before, to today's seven billion, is the earth easy, the weight of human beings appears out of thin air, not natural resources like oil are the original mass of the earth. In order to build cities, human beings have moved the resources that are automatically allocated by the earth at will, resulting in changes in the interior of the earth's crust and the load-bearing of plates.

As a result, the earth's plates slowly collapse inward, and every time it collapses, the earth shrinks a little, and every time it shrinks, the mass of the earth increases a little, and slowly, the mass becomes larger and larger, and one day, the earth shrinks infinitely, and then becomes a dead ball. Almost all of the Earth's energy comes from the Sun, so the Earth gains weight because it absorbs sunlight. We know Einstein's photoelectric effect, light is composed of photons, which is a real substance, so the light day after day, year after year, brings a huge weight to the earth, and it is also the basis for the survival of all things.

Light is absorbed by plants, plants grow through photosynthetic effects, animals feed on plants, and the sun participates in the earth's biosphere. On the other hand, it is said that fossil fuels are formed by animals and plants over hundreds of millions of years, so oil, natural gas, coal, etc. are inseparable from sunlight.

This is said by us human beings ourselves, the main body is human beings, and the burden is getting heavier and heavier for human beings. In fact, there is no impact and burden on the earth, so the environment is getting worse and worse, and the living environment of human beings is becoming more and more fragile, but there will be other species to replace the status of human beings, so everyone is responsible for protecting the environment.

One might say, why do humans know that the Earth is getting heavier and heavier now? Because the earth cannot be weighed, it is because they ignore the law of gravitation. With the advancement of science and technology, we can monitor the trajectory of the earth, and with the slight change of the running radius, we can calculate that the mass of the earth is getting heavier and heavier!

The earth receives sunlight every day, plants and other plants will photosynthesize and grow, and most objects will also absorb light, and this part of the energy will accumulate on the earth in the form of mass, and it will continue to accumulate, so the earth will become heavier and heavier.

This is because the earth has changed over hundreds of millions of years, and many new substances have been produced, and the ozone layer is getting less and less, and the gravitational force is getting smaller and smaller, so it is getting heavier and heavier.

Because in the process of human development, the damage to the environment is getting bigger and bigger, the number of people is increasing, and the things made are getting heavier and heavier, so the earth will become heavier and heavier.

It's because humans use some things to create something new, so the earth will get heavier and heavier.

3. A very small part of the matter on the earth is actually the first other stars in space. In fact, for us, just like a part of the matter is not created out of thin air, it may also be because of the collision of celestial bodies or the slippage of some celestial bodies left on the earth, and combined with the earth's environment to form a part of the earth's material, these materials eventually become a part of the earth, but in terms of the whole earth's material, it is also a very small part.

On the other hand, the material on the earth is a process of continuous modification and differential reintegration, so the matter will not be created out of thin air, nor will it perish out out of thin air, and the total amount will not change significantly, and most of the celestial slippage will also become part of the earth's material.

Due to the large universe, matter floats in space, and these different substances collide with each other, attract each other, and eventually form new matter, which then combines to form the earth.

According to the theory of the universe, all matter originates from the big **, and the matter produced by the big ** is relatively light element, forming stars under the convergence of gravity, and stars produce heavy matter, and these substances are ejected when they die, and the formation of the earth aggregates these elements.

Attracted by gravity, gravity is generated during the formation of the solar system, and some matter floating in space is attracted and aggregated together to form the earth.

<> will the soil or other things that humans bring back from their exploration of the universe increase the mass of the earth? Why? In everyday life, mass and weight are used in mass units, and weight is often used instead of mass, so you confuse mass and weight.

Conservation of mass is actually more used in the reaction process of the object, and of course, it can also be used for the object itself. If you grab a handful of soil from the moon to the earth, it will not break the law of conservation of mass, then the mass of the soil should be as much as it is, of course, because the gravitational pull of the earth is greater than that of the moon, and the gravitational acceleration is greater than that of the moon, so the weight of the soil will become heavier. By understanding the mass of an object at a microscopic level, you will better understand what conservation of mass is all about.

The mass of the object is equal to the sum of the masses of all the elements that make up the object, and the other way is to equal the sum of the masses of all the atoms that make up the object, so the chemical reaction will have the conservation of mass, because the chemical reaction is a reaction at the molecular level, and its total number of atoms is constant. Certain physical reactions can cause mass to be not conserved, such as nuclear transformation, where part of the mass is converted into energy release.

Transporting soil is only a change in the position of the object in space, and there is no reaction, let alone breaking the law of conservation of mass. Let's popularize the basic formula of physics: gravity (quantity) mass and acceleration due to gravity.

Since the gravitational acceleration of each region of the earth is not very different, the simple calculation of gravity is 10n kg. So the same kilogram of earth weighs about kilograms on the moon and 1 kilogram on Earth. But it's all a kilogram in mass.

First of all, you score clearly, what is the content of the law of conservation of mass? Conservation of mass refers to the chemical change, the mass before and after the reaction is equal, and of course the energy is also conserved before and after the reaction. I guess what you're trying to convey is the gravitational relationship between the Earth and the Moon.

f=gmm r, the mass of the earth and the moon has indeed changed, but the value of this change must reach a certain energy level, and the value within the range of the amount of change that g and r can calculate.

No, because the things brought back are very small and almost negligible, so it does not affect the overall quality.

Yes, because what is brought back from the universe can be studied, and scientific theories can be provided, so it can enhance the mass of the earth.

A: No, it can't be.

According to the "law" of conservation of mass, the total mass of a substance does not change before or after it undergoes a process of physical or chemical change.

That is: m (before the change) = m (after the change).

On Earth, in order to make an item as heavy and heaviest as possible, it is necessary to have m (before change) to the maximum. Because the sum of all the matter on the earth, the total weight, m(max) = m (the earth's own weight). So,The heaviest thing that man can make can only be as large as the earth's own weight

All human activities, from construction and factory operation to afforestation, can be regarded as "manufacturing" in a broad sense;

None of these activities will change the weight of the earth, the object, the product.

Of course, the above is only an analysis based on the current production activities of human beings.

And if we look to the future, humans can actually build up the ability to transport matter from alien planets to Earth:

In this case: 1 the earth's own weight will no longer remain the same, it will be increased, 2 it is not impossible and theoretically possible to continuously transport material from other planets to the earth, or to send another planet to the earth by technical means (so that it becomes one with the earth), and finally make the "mass of transported matter" greater than the "original earth's own weight".

In fact, not so long ago, AVIC Research successfully delivered lunar soil samples back to Earth.

But on the other hand, we can also look at the concept of "self-respect of the earth":

When materials from other planets are transported to the earth, then it can be considered that the "earth's own weight" has been renewed, changed, and increased at this time; In this conceptual understanding, it is not possible for any manufacturing activity (on the earth) to create anything heavier than the "earth's own weight".

At the same time, we can also look at the concept of "manufacturing".

The process of transporting material raw materials from other planets to the earth may not be called "manufacturing" in itself; The "manufacturing" activity can only begin after the transportation and the "earth's own weight" change, and it is not possible to produce items beyond the "earth's own weight" in the subsequent "manufacturing" activities.

It is impossible, because energy is conserved, and to make something heavier than the earth from the materials of the earth itself is equivalent to creating matter out of thin air.

No. Because human beings can only use the materials on the earth to make things, and the mass is conserved, it is impossible for human beings to make things on the earth that are heavier than the earth.

It is impossible, everything on the surface of the earth is a gift from the earth, and these things are simply a drop in the bucket compared to the earth.

The materials used in human construction are all taken from the earth, which does not make the earth heavier, but only changes the distribution of surface materials, and the result is that the center of mass of the earth changes, which in turn has a slight impact on the operation of the earth.

There are many large-scale projects built by human beings on the surface of the earth, and the greatest impact may be on large hydropower stations, and the quality of the hydropower station itself is not worth mentioning, but because it blocks the flow of water, the water body gathers in some areas, of course, it also causes changes in the quality of surface materials, and the mining of various minerals will also lead to changes in the quality distribution of surface materials.

But the impact on the planet is minimal, and all humans do is transport a little bit of mass from one place to another. According to satellite data analysis, the construction of large dams such as the Hoover and the Three Gorges has a slight impact on the earth's mass center, and in the long run, it has a slight impact on the movement of the earth, and even the earth's orbit, but it will take a long, long time.

The earth itself is close but not a sphere, due to geological activities on the formation of various mountains and rivers on the land, lakes and oceans, simply think about it, the composition of the land is rocks, the rocks must be heavier than the water in the ocean, and the land is so much higher than the ocean, so the mass distribution of the earth itself is uneven.

The uneven distribution of the earth's mass is also the reason why the asteroid hits the earth, every time the asteroid flies to the earth, the gravitational force is unequal, and the asteroid has a small volume and mass, and the shape is irregular, under the influence of the earth's gravitational force for a long time, the orbit gradually deviates from the intersection point of the earth's orbit, and there is an impact event.

The only factor that makes the earth heavier is the influence of extraterrestrial factors, the earth is hit by small meteorites every day, and there will be large-scale impacts in tens of thousands of years, plus there are dust and air masses near the earth, which will also be attracted to the earth, and some of the solar wind particles exposed by sunlight will also reach the earth's surface.

The building on our earth, the raw materials are taken from the earth, and then the building is completed, and the lead shed is equivalent to the raw materials and the materials are returned to the earth itself. Secondly, our human production and life will consume some of the earth's non-renewable resources, so it seems that maybe the earth will become lighter.

For this problem, some netizens believe that the outbreak of population increase and the impact of human activities have increased the mass of the earth to a great extent, but planetary experts said that if any kind of celestial body in the universe is not under the influence of external factors, the mass of the loafer type remains basically unchanged, even if the mass changes, the change will not be very large, so even if the population of the earth exceeds 8 billion in the future, 9 billion, it will not have much impact on the mass of the earth. Whether it is population growth or building growth, the energy and resources required for growth are obtained from nature, so the birth of new things is often the transformation of old things.

No, because the earth is a whole, and in general there will be no more raw materials, because all the raw materials come from the earth.

The earth is produced by volcanic eruptions, magma flowing everywhere, and chemical reactions with various substances to produce new species, the elements are conserved, there are so many elements that exist from the beginning, it is impossible to create from nothing. It's just that there are so many of them that they are classified according to the different characteristics of the elements.

The earth was created due to a cosmic great ** many years ago, and the reason why there are so many elements is that ** later produced a large number of elements with high atomic numbers.

The earth is created because the distance between the earth and the sun is relatively moderate, there is oxygen and water, which is suitable for the survival of animals and human beings, and there are so many elements because it needs to meet the needs of human beings and creatures for survival.
