I can not go into too much detail here but the basic idea of it is this:
When you fire a laser (which is focused light) on a veeery specific wavelength at an object, that object will release whats called a photon.
This photon carries more energy away in the form of light than it absorbs. What does that mean?
Well heat is one of the, if not THE, most basic form of energy. In fact its so basic that conveying heat energy into other forms of energy is one of the most basic principles we utilize in every day life.
Since Heat is energy, taking away energy is cooling things down. Thats why "Cold" is not really a status but rather the absence of energy in a system.
Now here we go back to the photon. When a photon takes energy with it, the object looses that energy and thus looses heat and cools down.
Now we are not talking about a car or an apple here of course. But rather about atomic and molecular samples.
This technique is for example used to cool these samples to absolute zero.
So yeah.
SCIENCE

but the object doesn't absorb any of the photon energy you're shooting at it (the laser beam) ?

As is said i am not that well versed in this kind of science but apperantly the energy that the photon caries away from the object is bigger than the absorbed energy from the laser. Which kinda makes sense.Killua said:

So essentially they fire a laser to free a photon which in turn carries away more energy than is brought in thus cooling the thing

sounds feasible i guess
i'm not great at physics either

Blue, actually. Although I suppose blue hues can look greenish.

well i could tattoo a rose black too
Only one human so far has been directly hit by a meteorite.
