Is there a limit to how hot matter can get?

Answer 1

This is a tough question, one that does not exactly, as of yet, have an answer. There is a temperature limit where our mathematical equations will begin to break down, or not work properly when a certain temperature is reached. whether or not this means that in physical reality the laws of physics break down at this limit, or simply do not allow it at all is unclear. However, one can think of this conundrum in another way, and than extrapolate their own hypothesis. Heat is the measure of how much heat energy a particle has, and heat makes particles vibrate at certain speeds, depending on how hot it is. now, in a universe with unlimited energy, if you keep on giving a particle more and more energy, it will continue to vibrate faster and faster, until it nears the speed of light. However, the particle cannot actually reach the speed of light, so it will continue to te get hotter in minuscule degrees. For example, if he speed of light is 5, then the particles speed will go from 4.9 degrees to 4.91 degrees, and from that to 4.92 degrees and so on. therefore, the particle can never get hot enough to reach the speed of light, therefore, there is a maximum temperature, but that molecule can get indignantly hotter such as 4.999999999999999999999 degrees. So, in conclusion, there is limit to how hot something can get, but, at the same time, the same particle can continue to become infinitely, if not minutely hot. :)

Answer 2

Yes, there is a theoretical limit known as the Planck temperature, which is around 142 nonillion degrees Celsius. At this temperature, the laws of physics as we know them break down, and it is believed to be the hottest possible temperature in the universe.
