Depressive particles, or negative Kelvin temperature

    I read the news about the return of Nibiru article here , watched the video, laughed about -4 degrees Kelvin for a long time. He told his brother (a nuclear physicist by training) and he said to me "I have not reached such a degree of abstraction that I would imagine negative kinetic energy." Next come unscientific reasoning about how negative kinetic energy should look.

    I hope everyone remembers from the course of physics that the temperature of a substance is the kinetic energy of the molecules that make up a given substance.
    In order to imagine something ... be it a picture, a program, or negative kinetic energy, I use analogies, images, something similar, something unique ... well, I began to wonder how it might look. The image of a particle at rest comes to mind, which inhibits other particles approaching itself, while remaining at rest.
    Imagine this in more fun images, namely in people.

    For starters, a simple example (1).


    There are two particles ... one is hot
    Smile
    (in our case, this is one of two comrades, excited by the idea to go rollerblading, or hang out all night on the span, in general, light up), the other is cold
    Smile
    (in our case, this is the second comrade who cramped after a hard working week, and the maximum that he has enough strength to force himself to do is to sit at home with his head in the telly or sit down to read a popular science hub). In this example, both particles are at a positive temperature.
    We will make these particles exchange energy by closing them in a closed confined space (a heated friend went after his shy friend and tries to stir him up to go to a party) until their energy is completely equalized, i.e. substance temperature. In our example, we get two particles with the same temperature (Or in other words, friends were going to go to a club, play billiards and drink tea)

    The following example (2).


    With an even hotter first particle
    Smile
    (this time this friend came to visit his friend in another city ... without warning, by chance, at work), and the second particle, which is at absolute zero ... i.e. alone ... (that is, the second comrade sleeps after a working week and a daily shift)
    Smile

    We put them together in a confined space, mix, but do not shake, and wait for the energy to equalize.
    SmileSmile
    We got two friends who agreed to drink juice on a bench near the house, recalling the exploits of youth, and reflecting on what would come sooner - old age, or the end of the world.

    What will happen in the following example (3).


    This time, the first particle is heated even more (just in case), although it may be necessary for the experiment to use several hot particles, because some may die or freeze before the end of the experiment.
    SmileSmileSmile
    and one cold, with negative kinetic energy ... or “depressive” particle
    Smile
    (why I called it depressive, it will become clear a little further).

    The energy of one hot particle may not be enough to warm a depressive particle to a state of positive temperature. Those. in the language of physics - a frozen “depressive” particle will continue to be at rest, while hot particles will cause their speed to decrease (or take away the temperature of hot particles). Those. it will slow them down remotely, even before contact, because in the event of contact they will probably stick together in one frozen body (here thoughts arose about a black hole).
    As a result, we get cooled particles
    SmileSmileSmile
    flying past a depressive particle, which is possible only slightly heated
    Smile
    while remaining a particle with negative kinetic energy.

    Instead of a conclusion.


    Perhaps the discovery of temperatures below absolute zero and negative kinetic energy is not far off, even if this is not possible from the point of view of modern science. Or, as I was advised here, for the sake of completeness, a “depressed” particle should move at the speed of light, then this will look like a ring-shaped axis of temperatures. Although I think most of everything written above will fit for the topic of psychological training “there are no perpetual motion machines, there are perpetual brakes” or ideas for a fantastic thriller about “carefully, depressing particles”.
