If there is no perpetual motion machine, why can the universe run indefinitely?

Answer: Mass and energy in the universe are always transforming into each other, but the total amount remains the same, and mass and energy are conserved. In addition, the total kinetic energy of the universe is conserved, so that the motion in the universe will not stop unless the universe collapses back to the state before the universe is large.

In physics, a perpetual motion machine refers to a machine that does not need to input energy from the outside world, or has only a single heat source, and continuously does work on the external energy; The former is called the first type of perpetual motion machine, which violates the law of conservation of energy; The latter is called the second type of perpetual motion machine and violates the second law of thermodynamics.

Perpetual motion machine does not refer to the machine that can move forever, the meaning of the perpetual motion machine does not consume any energy and continuously does work outward, there are many people and celebrities in history who are obsessed with the development of perpetual motion machine, but the discovery of the law of conservation of energy and the law of thermodynamics makes people know that the perpetual motion machine is impossible to achieve, but until today there are still people obsessed with the perpetual motion machine, creating a variety of perpetual motion machine models.

If the perpetual motion machine is simply summarized as an eternally moving machine, each of us is actually a perpetual motion machine, because the electrons inside the atoms that make up our body are constantly moving, more precisely, all the particles in the universe are constantly moving, but you can't let the movement of the particles help you do work, so the universe itself is not a perpetual motion machine, because it can't do work externally.

The fundamental goal of the perpetual motion machine is to "get it without work", and the machine that can always move but does not do work can only be said to be "not working" and not "getting", so the so-called perpetual motion machine we see now is at best a toy.

Although the universe is not a perpetual motion machine, but the universe cannot run indefinitely, modern cosmology believes that the universe ** in 13.8 billion years ago a big **, then since the universe has a beginning, then there should be an end, scientists have observed that the universe is still expanding faster than the speed of light, so the final outcome of the universe is likely to be a big tear.

The so-called great tear refers to the continuous expansion of the universe resulting in the continuous increase of the distance between matter, and one day all particles from the universe will be torn apart by the expansion of the universe, including all the particles that make up our body, so the great tear can be called the end of the universe.

The repulsive force generated when the universe is big and the direct gravitational force of various substances in the universe, the interaction between them makes the universe run, but when there is a change at a certain time, the universe will also disappear.

Because the reason why the earth can rotate all the time is because it does not encounter enough resistance, and without resistance, everything in the universe will always maintain a constant state of motion. Although the Earth's rotation is gradually slowed down by the gravitational pull of the Sun and the Moon, this effect is so small that we don't feel it at all, and it may not affect the Earth's rotation until the Sun and the Earth are destroyed.

Humans once wanted to use the principle of the earth's motion to make a perpetual motion machine. But it is clear that this idea has been overturned. The Earth revolves around the Sun. This is based on a certain force.

Of course not, but the length of time is completely beyond our imagination, because the universe is a game scene running on a large computer (server), and everything in the universe (including people and things on the earth) is an element in the game. There's another kind of life playing the game. We humans have souls, so their role-playing, just like we play online games, the characters in the games we play will consider whether the machine they are in (the software, that is, their universe) is a perpetual motion machine?

It's unimaginable for them, but what will happen if we shut down the server, they simply can't imagine.

Generally speaking, a perpetual motion machine refers to a machine (system) that can continue to do work on the outside world without external energy input. ）。You say that the universe is a perpetual motion machine, but what is the outside world of the universe? What has the universe done again?

If a perpetual motion machine is a system that is constantly in motion, then everything we can see is a perpetual motion machine, because the molecules that make it up are in thermal motion all the time.

The universe may be a reincarnation machine, a perpetual motion machine in the ordinary sense. However, the scientific perpetual motion machine refers to a machine that not only makes itself move forever, but also can do infinite work to the outside world, which probably does not exist.

All matter is moving irregularly and endlessly, that is, everything in the universe is a perpetual motion machine.

Summary. Hello, glad to answer for you.

Although the universe is full of infinite energy, various forms of energy are always transforming each other on a large scale, and it does seem to be comparable to an infinitely powerful perpetual motion machine, but everything in the universe is born and destroyed, and the current universe is logically from the big **, and it is constantly expanding at high speed, according to theoretical reasoning, at a certain time, the expansion stops, the universe begins to contract, and it is reduced to the beginning of the singularity, although the process is the effect of energy, but this energy cannot be utilized, according to this reason, the universe is not a perpetual motion machine. However, according to Einstein's mass-energy equation, matter and energy can be converted into each other, as long as there is matter, it means that there is energy, which seems to be a perpetual motion machine.

The universe is constantly expanding, so he has been doing work on things outside the universe, so is it a perpetual motion machine?

Hello, glad to answer for you. Although the universe is full of infinite energy, various forms of energy are always transforming each other on a large scale, and it does seem to be comparable to an infinitely powerful perpetual motion machine, but everything in the universe is born and destroyed, and the universe is now from the big **, and it is constantly expanding at high speed, according to theoretical reasoning, at a certain time, the expansion stops, the universe begins to shrink, and the restoration is almost the beginning of the singularity, although the process is the role of energy, but this energy cannot be utilized, according to this reason, the universe is not a perpetual motion machine. However, according to Einstein's mass-energy equation, matter and energy can be converted into each other, as long as there is matter, it means that there is energy, which seems to be a perpetual motion coarse dust state.

Won't the universe expand indefinitely?

Regarding the question of whether the universe will expand indefinitely, scientists currently have the following inferences: first, the universe is infinitely large, and there is no limit to expansion; Second, when the cosmic hail state expands to the limit, it will eventually go through the process of expansion-collapse-re-** like the evolution of stars, in short, it will return to the state of singularity, and when all energy is restored to the original, it will be ** again, forming a new universe.

First of all, we must understand what exactly is a perpetual motion machine.

It's not literally a "machine that turns forever", but it doesn't need to consume energy and does work forever, or takes heat from a single heat source and makes it completely successful without causing other changes!

Therefore, it is not rigorous to say that "the universe is a perpetual motion machine", because the universe encompasses all things, and there is no such thing as "external work" or "heat from a single heat source"!

To put it simply, the question should be: "Is the universe a machine that rotates forever?" (Such a machine is not what we often call a perpetual motion machine, but a perpetual motion machine in the literal sense for the time being).

The universe is a self-consistent perpetual motion machine, and the universe is also a binary.

The law of random hardware coding of the autonomous antivirus computer system.

Why does the universe grow in cycles? This is due to the fact that the universe is a closed system of positive and negative unity, a closed system with only energy conversion and no energy loss, which conforms to both the laws of conservation of mass and energy and all the laws of thermodynamics.

But why can't our computers be perpetual? The reason is that the computer can only encode the software autonomously but not the hardware naturally, and the computer also uses and consumes energy.

Why can't human beings create a perpetual motion machine? One of the reasons is that the yang and yin factors that make up all things have not been found, and the second reason is that human beings are too greedy, trying to make the perpetual motion machine endlessly output energy in the resistance environment of the earth, which violates the laws of nature.

Can the machine succeed? If it succeeds, the universe will soon be **!

No, all the energy in the universe today comes from the universe.

The singularity swelled rapidly. The singularity is an infinitely dense point with infinitely high and infinitely small temperature and density, and what exactly triggers the rapid expansion of the singularity is still inconclusive!

Therefore, according to the theory of the universe, the universe is not a perpetual motion machine, but the universe exists for a time far beyond our imagination, and as long as the universe exists for one day, it is in "perpetual motion"!

At the same time, for our cognition, the sun and the earth are also a kind of perpetual motion machine, their billions of years old are basically equal to "permanent" for human beings, and we regard solar energy as a renewable energy source.

That's the best illustration!

Finally, the first law of thermodynamics.

That is, the law of conservation of energy.

It is the basic law of the day, and countless attempts at "perpetual motion machines" in human history have ended in failure!

Yes. Because the universe is an existence with a lot of matter and power, it will be a perpetual motion machine.

Personally, I don't think the universe is a perpetual motion machine, it just has more energy, and the consumption is relatively not obvious, but if it takes a long time, it will definitely be consumed.

I don't think the universe is a perpetual motion machine. The universe is also consuming its energy, and one day the energy will disappear.

1. Theoretically, a perpetual motion machine is a machine that does not rely on the help of external energy, or that as long as energy is input once, it can do work permanently. This machine is theoretically possible, but in reality it is impossible to build. As early as the 13th century, there were studies on perpetual motion machines, but unfortunately they all failed.

Although it can move autonomously without stopping, it will stop after a while. Centuries have passed now, and no one has studied it. There are a lot of goods on the web that use this as an excuse, and we have no doubt that they are all fake.

2. The theory that a perpetual motion machine cannot be manufactured exists, but it cannot be manufactured. The reason is also very simple, that is, it violates the laws of conservation of energy and thermodynamics. It is clear in thermodynamics that a "type 1 perpetual motion machine" is not possible.

Related experiments have also been done many times, the most famous is the "magic wheel". After that, many people imitated and copied, but like the first generation of magic wheels, they did not achieve non-stop rotation. After all, there are many resistances in life, such as the earth's gravity, wind, etc., which will prevent the generation of perpetual motion machines.

3. The universe is not a perpetual motion machineThere are many things in the universe that look like perpetual motion. For example, the rotation and revolution of the Earth are actually affected by the gravitational pull of other planets. And through the observation of scientists, some planets are trying to get out of their fixed orbits and undergo certain changes.

Leonardo da Vinci once did the same experiment, and ended with the words, "Eternal motion fantasists, how futile your quest is".

does not exist. Because a perpetual motion machine violates energy conservation, it does not exist. The universe is also not considered a perpetual motion machine because there is a gravitational attraction between the cosmic celestial bodies.

Perpetual motion machines only exist in the imagination of human beings, and do not exist in real life. The universe is dynamic, and there will be moments of death, which is not a perpetual motion machine.

At present, perpetual motion machines do not exist, they are just a concept, and it will be very difficult to manufacture them in the future. The universe, because it is always in a state of expansion, is not considered a perpetual motion machine.

does not exist. Energy can neither be created in a vacuum, nor can it disappear in a vacuum. The law of conservation of energy must be followed, and naturally there is no perpetual motion machine.

The universe is no exception.

Theory exists?? It's against the two laws.,Why do there still be theories?。。。

A perpetual motion machine is a machine, and the universe is not a machine.

The end of physics is mathematics, the end of mathematics is philosophy, and the end of philosophy is theology.

Junior high school knowledge, it is recommended to ask after graduating from junior high school.

Perpetual motion machine, as the name suggests, has two requirements: first, it must be able to move all the time, that is, perpetual motion; Second, it has to be a machine, that is, it can do external work.

In the universe, everything from atoms and electrons to planets and galaxies can always move. Why? In the first chapter of junior high school physics, Newton's first law says that as long as an object is not subject to external forces, it will always be stationary, or move in a straight line at a uniform speed.

However, if you want to do external work at the same time, you will not be hit, which will cause the object to stop for a limited time. This is the result of the conservation of energy, which is the first law of thermodynamics.

It has also been said that the most important thing in the universe is energy, from the scorching hot air to the warm ocean. Use them for work, and they are inexhaustible. However, the second law of thermodynamics says that the flow of energy is directional, and it is not something that can be used to do work without paying a price.

This is a consequence of the principle of entropy increase, the second law of thermodynamics.

I wonder if you understand this?
