Absolute zero stops all atoms, but it doesn't freeze the speed of light. We all know that with the discovery of modern science, human beings have been out of control on the road of exploring the universe and transforming nature, and in more than 100 years, we have taken a big step forward and made countless brilliant achievements, which have exceeded the sum of the past thousands of years.
However, humanity has also come to realize its own insignificance in the universe. 13 billion years ago, the universe was large, and the temperature inside the singularity was said to have reached 15 trillion billion degrees; For us, this is an astronomical amount that is difficult to estimate.
The maximum temperature exceeds the limits of human imagination, so is the same for the minimum temperature? It's really not, everyone knows that the lowest temperature in the universe is the so-called "absolute zero", more than 200 degrees below zero. This makes one wonder:
Why is absolute zero so low?
Because the essence of an object is the movement of atoms, the more intense the movement of atoms, the higher the temperature of the surface of the object; The slower the atoms move, the lower the surface temperature. As the temperature approaches absolute zero, the atoms inside the object become slower and slower; When absolute zero is reached, even the atoms will be frozen.
Some people say that when humans go to an environment of absolute zero, the first thing that freezes is not life, but thought: this is really not "sensational", absolute zero, it is so terrible. So, can absolute zero freeze the fastest photon in the universe?
Can't even the speed of light withstand the power of absolute zero?
Of course not. Why can photons move at speeds of up to 300,000 kilometers per second? Because it is not a substance. That's right, a photon is a "body of energy", and in general, the speed of light represents the infinity of the mass of an object; But photons have no mass.
In other words, no matter how low the temperature is, it is impossible to hinder the speed of light. Unless, like a black hole, the curvature of space-time reaches an almost infinite degree to make the photon stop moving forward.
-
Temperatures of absolute zero can reach as low as -273, and anything can be frozen. But the speed of light cannot be sealed, because the speed of light is not limited by temperature.
-
The propagation speed of light is indeed beyond the control of temperature, in such a low environment in the universe, light can fly normally at a normal speed, so on the earth, even if the absolute 0 degree of the earth is so low, it is impossible to limit the propagation of light, and the speed of light is the carrier of its motion is light itself, and the material of light itself is negligible, since light is a matter that can be ignored, then absolute zero is impossible to control this kind of object with almost no matter.
-
In fact, absolute zero is the existence of a concept, human beings have not found it in the universe, or detected it, absolute zero is minus 273, if this temperature is reached, the light may be frozen.
-
Personally, I think absolute zero must be very scary, anything below absolute zero can be frozen, and the speed of light can also be frozen.
-
I think absolute 0 degrees is really scary, he can freeze anything, it makes people feel scared, including the speed of light.
-
I think it's terrifying, and it should be enough to freeze the speed of light.
-
Temperature: Relative to material particles (molecules, atoms, electrons, photons......Density is directly proportional to velocity.
-
Light has no mass, how to freeze.

The reason why the earth is suitable for human habitation is because the temperature and environment of the earth are very suitable for the survival of life, even if the temperature of the earth can reach more than minus 200 degrees, if human warmth measures are done well, I believe that human beings can also survive in this environment.
Now the temperature of the earth is rising, relatively speaking, the absolute low temperature is a point of concern for scientists, at present we have a technology, this technology can produce 200 million high temperatures, this high temperature is higher than the surface of the sun, but this temperature is certainly not the high temperature limit that human beings can create, scientists are not interested in this high temperature, but interested in the lowest temperature of the earth, the lowest temperature found by humans can reach minus 273, this low temperature is also called absolute zero.
In other words, this temperature can freeze all moving objects, so can light be frozen by this absolute zero? First of all, let's talk about the temperature of the temperature, the temperature is determined by the speed of particle movement, if the particle movement speed is too fast, the higher the energy generated, so it can produce high temperature, as long as the particle movement speed is constantly increased, the temperature can be continuously increased and absolute 0 degrees, which means that the energy is very small, almost unchanged, so relatively speaking, there is an absolute 0 degrees, and absolute 0 degrees is impossible to freeze the light, because the propagation speed of light is also very fast.
And the propagation speed of light is indeed beyond the control of temperature, in such a low environment in the universe, light can fly normally at a normal speed, so on the earth, even if the absolute 0 degree of the earth is so low, it is impossible to limit the propagation of light, and the speed of light is the carrier of its movement is light itself, and the material of light itself is negligible, since light is a material negligible thing, then absolute zero is impossible to control this kind of object with almost no matter.

Absolute zero is the absolute cessation of the motion of atoms, absolute rest, there is no concept of temperature, and the speed of light cannot exceed absolute zero.
-
Absolutely. Any object in an environment of absolute zero will stop moving and be at rest, and photons will be at rest in the case of absolute zero.
-
Absolute zero is not zero, it's just a conjecture, and physicists believe that this temperature is unattainable.
Absolute Zero Absolute zero represents a temperature at which all the molecules and atoms that make up matter cease to move. Motion refers to all spatial, mechanical, molecular, and vibrational motions, including some forms of electronic motion, but it does not include "zero-point motion" in the concept of quantum mechanics. This motion cannot be stopped unless the agglomeration system of the moving particles is dismantled. >>>More
In physics, the Kelvin temperature was introduced for the convenience of research, and "absolute zero" was used as the starting point of the Kelvin temperature. Nowadays, people can easily get millions of degrees of heat, but they can't reduce the minimum temperature to absolute zero. For this reason, in thermochemistry, there is such a law: >>>More
Temperature is a measure of the thermal motion of a system, but the solution of the Schrödinger equation tells us that the system still has thermal motion even below zero. The third law of thermodynamics says that when the temperature approaches zero, the entropy change caused by the possible changes in the system approaches zero. One of its equivalent descriptions is that absolute zero is unattainable. >>>More
No. First of all, electrons are not immobile at absolute zero. It has energy, according to the uncertainty relation, x*p"h, and then using the Schrödinger equation, and then according to the derivative method, we can get his minimum value, which is the ground state energy, and this energy must not be zero. >>>More
Absolute zero, at the Celsius scale, and the thermodynamic scale is expressed as 0 K. That is, when the kinetic energy of the particle is as low as the lowest point of quantum mechanics, then we can say that the matter has reached absolute zero. To put it simply, temperature is the average kinetic energy of atoms or molecules in a substance. >>>More
