What happens if a beam of light passes through an area of absolute zero?

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.

At absolute zero temperature, the kinetic energy is 0 and there is no energy exchange. What is light, is it considered a substance?

In quantum mechanics, all particles are divided into two categories according to a characteristic quantity called "spin". One is the so-called "fermions", that is, particles with spin as half integers; One is the "boson", which is a particle with an integer spin. For example, the electrons and protons that make up our world belong to fermions, and photons and gravitons are bosons.

Although light is not a physical object and has no static mass, light has a moving mass, and its essence is an energy. The photoelectric effect is a phenomenon in which light exchanges energy with other substances. Okay, whether absolute zero is achievable or not, open your mind and see what happens when light passes through an area of absolute zero.

As mentioned above, temperature is the manifestation of the kinetic energy of particles in matter, so first, there must be at least one particle in this "absolute zero" region, which is motionless, so that the so-called absolute zero region refers to the particle itself, so what happens when the photon encounters this particle? Light is a kind of energy, and when a photon encounters this "absolute zero" particle, it will inevitably destroy this "balance", and at the moment of encounter, there is no "absolute zero".

I think light can be absorbed or changed in some other way, because light is fast, but time is refracted through an absolute zero region.

You should notice these twists and turns, because the speed of light is fast, but when it passes through an absolute zero area, time is refracted.

Then, it is possible that this light will be refracted and reflected everywhere, and it will not pass through anyway.

I think there will be some physical or chemical changes, and it will look amazing, don't you think?

Hahaha, how incredible it is, in this case, the light will freeze.

I think the light will be frozen, and you can see a distinct constancy of light.

I think the light might be absorbed or something else changed.

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.

It doesn't have to do so much with temperature, so it's hard to happen.
