Hypothetically there’s a limit to how hot black body mechanics can fuction. As an object gets hotter it starts to glow. First on longer wavelengths like radio but also working up to shorter wavelengths like infrared, visible light, and then ultraviolent. However, there comes a point when the wavelength produced by such heat is so short that it’s within Planck’s length and Quantum Mechanics says this can’t be possible.
However, this doesn’t actually prevent things from getting hotter than that, it just says that our understanding of physics breaks down at this point.
