Why can't we just keep heating matter past Planck's temperature? Planck's temperate or 10 to the power of 32 Kelvin is the hottest temperature possible. If you're shooting an atom with heat radiation and it reaches Planck's temperate why can't you keep heating it.

I do have a theory though - Lets say you're shooting an electron with a laser and heating it up. Every time an electron goes into a higher quantum state it requires more energy to bring it into the next one. At first the difference of energy required is not noticeable but eventually it requires more and more energy to further excite the electrons of the atom(s) being heated. After a long time some of the electrons are at such high energy levels that they require infinite energy to go into a higher quantum state.

    It isn't. That's it. – Physics Guy Aug 16 '16 at 00:54

    Where does it say that we can't? The Planck scale is, at this time, nothing but a speculation. – CuriousOne Aug 16 '16 at 00:54

    @CuriousOne Not a speculation, but very often misunderstood in popular science books. – Physics Guy Aug 16 '16 at 00:57
  • @PhysicsGuy: Can you cite a single measurement done at the Planck scale? – CuriousOne Aug 16 '16 at 00:59
  • The other question was more focused on kinetic energy and the speed at which particles vibrate. He asked if there was a hottest temperature possible, I'm asking why can't we go hotter than that temperature. – EasyPeasy Aug 16 '16 at 11:15
  • @CuriousOne Pick up a grain of sand and feel its weight. Now remember that the sand grain is about a Planck mass, and nothing can be lighter than a Planck mass, right? – user253751 Aug 16 '16 at 12:01
  • @immibis things can be lighter than plank mass, that's the maximum mass capable of holding a charge. – EasyPeasy Aug 16 '16 at 12:04
  • @immibis: I was asking about the Planck scale, not about one Planck mass. After all, we are also living on a pea size black hole... :-) – CuriousOne Aug 16 '16 at 12:04

    @EasyPeasy "That's the maximum mass capable of holding a charge" - this capacitor in my left hand says different. (Each plate holds a charge and weighs more than a Planck mass, even though the capacitor doesn't hold a net charge) – user253751 Aug 16 '16 at 12:04
  • he Planck mass is the maximum allowed mass capable of holding a single elementary charge. - A single elementary charge – EasyPeasy Aug 16 '16 at 12:09
  • @EasyPeasy source? Why is this capacitor plate not capable of holding a single elementary charge, even though it's capable of holding more than one? – user253751 Aug 16 '16 at 12:19
