What does the universe look like when it is at its lowest temperature

The current background temperature of the universe is about 3 K, which is about Celsius. The quest for absolute zero has always been ongoing, and the lowest temperature ever reached is about, almost absolute. However, humans will never be able to cool down to degrees Celsius artificially, so the universe should not be able to reach this temperature (although its background temperature is still decreasing, like cutting an apple in half, then halving, and then halving, but it can never be cut without it), so let alone below this temperature.

Temperature is a representation of energy, which is reflected in the movement of molecules, and absolute zero means that even the movement of molecules has to stop, which is impossible to achieve, so...

So far, scientists have determined that absolute zero is impossible.

If you reach absolute zero, all particles stop moving, and in relativism, ions can't stop moving, so absolute zero can't be reached!!

The universe has been cooling since the beginning of the megaloiss**, and now there is about 3 K of microwave background radiation left.

At absolute zero, the distribution of matter is completely ordered, or the entropy is 0, and the energy of the universe below the absolute temperature is much higher than that of the positive temperature, and the negative temperature can be seen.

It is impossible to reach this temperature, and if this temperature is reached, all matter in the universe will be stationary, and the temperature of the universe when it was first created was 3k, which is higher than the low temperature reached by humans, and humans have tried to reach degrees Celsius.

The third theorem of thermodynamics: absolute zero is unattainable in degrees Celsius, but can only be approached infinitely.

If we insist on reaching absolute zero, according to the Guy Lussack experiment of the three ideal gases of thermodynamics, the volume of matter is zero, that is, the matter disappears. (It's impossible!) Give it up! ）

When the universe reaches absolute zero, everything is at absolute rest, completely dead, so there will be no lower temperatures.

Absolute zero is obtained by intersecting the x-axis of the reverse extension line of the gaseous equation image, which has no practical significance and only represents a theoretical state.

According to the third theorem of thermodynamics, absolute zero should be degrees Celsius which is unattainable.

The temperature in the coldest place in the universe is Fahrenheit (degrees Celsius), which is more than three times colder than the coldest place on Earth.

The coldest place in the universe is an object called the Boomerang Nebula, located in the constellation Centauri, about 5,000 light-years from Earth, which is the coldest object ever observed in the known universe.

The Boomerang Nebula is a reflective cloud of dust and ionized gas, a young planetary nebulaBut at the center is a dying red giant, once a star much like our sun, which has been shedding its outer layers of material in the final stages of its life. Although this is in line with the scientists' opinions, scientists have found that this star is losing mass about 100 times faster than other similar dying stars.

What's more, the red giant is losing mass 100 billion times faster than Earth's Sun, a staggering rate. According to NASA, this has actually led to the loss of almost twice the mass of our sun over the past 1,500 years as the dying red giant. And, because these gases are ejected at a speed of 101 miles per second (164 km/s), a large amount of heat energy is released.

The result is a very cold region of space, with scientists detecting temperatures deep inside the Boomerang Nebula at -458 degrees Fahrenheit or -272 degrees Celsius, with individual regions reaching absolute zero, or degrees Fahrenheit (degrees Fahrenheit). This makes it more than three times colder than the temperature record for the Fuji Dome in Antarctica in 2010, when the temperature was recorded at minus Fahrenheit (degrees Celsius).

The Boomerang Nebula is so cold that it is even lower than the temperature (Fahrenheit, Celsius) of the cosmic microwave background (cmb) left by the cosmic large**. In fact, the light of the CMB was absorbed by the Boomerang Nebula, which was quickly discovered when the nebula was first discovered in 1980.

How was the Boomerang Nebula discovered?

In 1980, cosmic astronomers Keith Taylor and Mike Scarrot discovered the Boomerang Nebula, unbeknownst to them at the time that it would be the coldest place in the universe.

The winds from the star can expand rapidly as they flow outward, causing a sharp drop in temperature, making it a cosmic refrigerator. Through this theory, in 1995 scientists came up with the temperature of the Boomerang Nebula.

In 2013, scientists confirmed this temperature using a large array of telescopes.

Scientists have discovered that the low temperature of the Boomerang Nebula is caused by the rapid acceleration of gasesWhy the red giant loses mass so quickly has become a new research topic.

According to research, the only way to eject so much mass at such an extreme rate is from the gravitational pull of two interacting stars, so scientists believe that there is a small companion star inside this dying red giant, which caused this phenomenon.

The next step for scientists is to find other, colder similar phenomena.

As for the Boomerang Nebula, the central star will eventually become a white dwarf.

There are two places in physics where you can't go beyond the thunder pool, one is the speed of light, and the other is absolute zero. Your idea crossed two thunder pools at the same time, which is not simple. But at the moment, your idea is not going to come true.

Assuming that your inference is correct, that time reversal can cause negative motion, then it is up to you to turn back time. Only the speed of light can turn back time, but according to the special theory of relativity, the mass of an object accelerating to the speed of light becomes infinite, and it is impossible to reach the speed of light, let alone the speed of light.

If you want to find a theory that can support your assumption, I'm afraid that the whole physics will have to be turned upside down.

The coldest object in the universe is the Dart Nebula, which has a temperature below -270. The Dart Nebula is formed by the gas ejected before the star dies. These gases are released at a very fast rate, reaching 165 kilometers per second, causing the temperature of the Dart Nebula to drop dramatically.

So how do you create negative motion? Could it be that it is a mysterious new dynamics that changes the microscopic primitive composition structure of matter?

According to the uncertainty principle, the more accurate the position of the atoms is, the less accurate the momentum of the atoms will be, if it reaches absolute zero, that is, all the atoms are at rest, then at this moment, the momentum of all atoms will become close to infinity, and they will also move at high speed in an instant, and once there is thermal motion, there will be a positive temperature (Kelvin).

And, what is negative motion?

There can never be a 0k substance.

Even if you try your best to get the matter to 0k

You have to observe it, only by the reflection of light.

Once a photon goes up. It gets energy. It's not 0k again.

0k should be an absolutely energyless state. You can't observe it either.

Then you can do your own research.

After all, the general opinion in the scientific community is different from yours now.

He can't reach absolute zero. The current view is this.

At the speed of light, mass is infinite. Time stops. This one. Hey, anyway, let's learn more things, don't think about these things now, go to university to specialize in research.

The lowest absolute zero, i.e. Celsius).

1000000000 (1 billion degrees Celsius) and above Cosmopolisal Large**.

At the moment when the universe is large, the temperature reaches infinity; After the universe is 10 minus 44 seconds, the temperature is about 10,000 trillion trillion (one trillion is equal to 10,000 100 million) degrees; After the universe was 10 minus 36 seconds, the temperature of the universe continued to drop, and the temperature at that time was about 10,000 trillion degrees; After the universe is 10 minus 32 seconds, the temperature is about 1 trillion trillion degrees; After the universe is 10 minus 12 seconds, the temperature reaches 10,000 trillion degrees; After the universe is large, it is 10 minus 6 seconds, and the temperature reaches 1 trillion degrees; After the universe is 10 minus 4 seconds, the temperature reaches 100 billion degrees, which is also the temperature of the supernova's core when it explodes; One second after the universe is large, the temperature drops to about 10 billion degrees; About 3 seconds after the big **, the temperature drops to 1 billion degrees, which is also the temperature inside the hottest star.

Absolute maximum temperature.

The energy of a particle is expressed by motion, and absolute zero means that all the atoms in the object are at rest and no longer have any thermal motion.

Then, the faster the particle moves, the higher the energy, the higher the temperature of the macroscopic matter, the particle itself has no temperature, and can only express its temperature through energy, so, under a certain pressure, the speed of each particle is close to the speed of light, and the energy tends to be infinite, that is, the limit of temperature, that is, the absolute maximum temperature.

Physicists have managed to bring the temperature to minus degrees Celsius, the lowest temperature known in the universe.

Sub-zero. That is, absolute zero. At this temperature, the particles will stop moving.

The lowest temperature in the universe is more than minus 10,000 degrees Celsius, and there is no universe big ** The theory that the universe is big ** is wrong.
