HOTTEST TEMPERATURE EVER? HOW HOT IT CAN GET? PLANK TEMPERATURE?


You might be drinking tea or something , i guess it is hot but do you know HOW HOT IT CAN REALLY GET?
As we all know there is absolute zero but do we know what is absolute hot , a point where it is so hot that it cannot get any hotter.

The highest recorded air temperature all over the earth is 56.7 degree celsius in Death Valley. 1090 degree celsius is the temperature of lava fresh out out the ground.  


Temperature of interior of sun
Surface of the sun clocks in at 5500 degree celsius but the centre where fusion occurs , it is amazing, temperatures there 15.7 million degrees celsius.When matter reaches at the temperature same as the interior of the sun enormous amount of energy is radiated away. If you can heat the tip of your pen at that temperature it will kill every person within the range of 1000 kms. Besides our sun is not even close to being the hottest place in the universe . The peak temperature reached in a thermonuclear explosion is 350 million kelvin but but but inside the core of a star 8 times larger than our sun on its last day of life as it collapses in on itself you would reach a temperature of 3 billion kelvin.


 WR 104
There is a star WR 104 , about 8000 light years away from us. Its mass is the equivalent of 25 times of our sun's and when it dies , when it collapses, its internal temperature will be so great that the energy emmited ,the gamma radiation it flings out into space will be stronger than the entire amount of energy our sun will ever create in its entire lifetime. Although it is 8000 light years away the effects it has on earth is that it will destroy a quarter of ozone layer from our atmosphere. 

Well if an object were to reach a temperature of 1.41*10^32 kelvin the radiation it would emit would have a wavelength of 1.616*10^-26th ( 1.616 into ten to the power negative 26th) of a nanometer which is the plank distance which according to quantum mechanics is the shortest distance possible in our universe , okay what if we added more energy? Wouldn't the wavelength will get smaller? Its supposed to but yet it can't. This is where we got a problem above 141 * 10 ^32 kelvin the plank temperature, our theories don't work , the object will become hotter than the temperature. It will be so hot that what it is would not be considered as temperature.
