Absolute 0 is -273,15 Celsius. At this point molecules are just frozen in time and don’t move so it’s not able to produce heat.

Temperature is a measure of particle movement. All movement stops at absolute zero, which is 0° Kelvin, or -273° Celsius, IIRC. What you're suggesting is literally impossible.

A good way to think about temperature in this context is that it is a measurement of how quickly atoms or particles are vibrating. When atoms/particles stop vibrating, they reach the lowest temperature it can possibly reach… at which point, our scales for measuring temperature stop, and nothing exists below it. This is at 0 Kelvin, –273.15°C, or –459.67°F. These represent the floor for temperature, so temperature cannot reach -10,000° because it’s physically not a thing.

Snippet to answer your curiosity:

It is commonly thought of as the lowest temperature possible, but it is not the lowest enthalpy state possible, because all real substances begin to depart from the ideal gas when cooled as they approach the change of state to liquid, and then to solid; and the sum of the enthalpy of vaporization (gas to liquid) and enthalpy of fusion (liquid to solid) exceeds the ideal gas's change in enthalpy to absolute zero. In the quantum-mechanical description, matter (solid) at absolute zero is in its ground state, the point of lowest internal energy.

Quantum gas goes below absolute zero

Negative temperatures show up in systems with limited numbers of states, which rules out things with normal translational or vibrational freedom. Sometimes it happens with spin states in a magnetic field. Negative temperatures are hotter than infinite temperature, with states with more energy being more likely, where at infinite temperature all states would be equally likely. If it had unlimited energy states, it would have infinite energy, which is impossible.

Zero absolute temperature means it's in the lowest energy state, so you can't get colder. It appears in the thermodynamics as the change of the number of states with energy going as 1/T, so you can't smoothly go below zero. Lower temperatures allow more large-scale coherence, such as superfluidty and superconductivity, so at many orders of magnitude lower temperature than previously observed, it's reasonable to think new pheonomena like this might arise.

Ya but what would have to happen for it to become a thing

Burning energy is just that, burning... Did you smoke anything just now?

For it to become a thing we would have to redefine our temperature scale to have more numbers below zero.

What would have to happen? Advances in quantum physics that cause us to adjust our temperature scales. Quantum states do allow for temperatures below the floors for K/C/F scales. But quantum conditions don’t extend to the majority of matter that we observe as our physical universe.

So it’s possible to go lower than the floors of our temp scales very specific, extreme, and limited circumstances* that don’t apply to the whole of our physical universe; therefore, from a practical perspective, they don’t matter when measuring temperature of the physical systems we know.

*As far as we’re now aware, and can measure. This may change as we learn more.
