i think that temp. can go up and up and up forever...
it all depends on if we can measure this super high temp. without destroying our instruments...
As knowing wave is also form of something existing. Microwave has temperature, as it warms the object which it hits.

If we heat the "gas of nucleons further to 10 trillion Kelvin, these subatomic particles will turn into disassociated quarks. We will now ha
ve a gas of quarks and leptons(the electrons and neutrinos).
If we heat this gas to 1 duadrillion Kelvin, the electromagnetic force and the weak force will become united. The symmetry SU(2) x U(1) will emerge at this temperature. At 10^28 Kelvin, the elecroweak and strong forces become united, and the HUT symmetries(SU(5), O(10), or E(6)) appear.
Finally, at a fabulous 10^32 Kelvin, gravity unites with the GUT force, and all teh symmetries of the 10-dimensional superstring appear. We now have a gas of superstring. At that point, so much energy will have gone into the pressure cooker that the geometry of space-time may very well begin to distort, and the dimentionality of space-time may change. The space around our kitchen may very well become unstable, a rip may form in the fabric of space, and a wormhole may appear.
Question - I know that there is such a thing as absolute zero where
the particles can't get any colder, but is there such a thing where the
particles can't get any hotter?
Not really. Temperature is a measure of average kinetic energy of the
particles, and the minimum value of kinetic energy is zero. There is no
maximum value, however.

The other limit would be infinite temperature. This is not as
crazy as it sounds. Temperature is formally a measure of the
probability of a system being in states of different energy, e.g. the
fact that the Earth's atmosphere has a temperature of 300 K (roughly)
tells you how much less likely it is for a nitrogen molecule to be at
10,000 feet altitude (where it has significant gravitational potential
energy) versus zero altitude (where it has none).
Zero temperature means formally that the system can ONLY be in the
lowest possible energy state: in our example, every nitrogen atom must
be on the ground. Infinite temperature means that the system can be
found with equal probability in all possible energy states, including
those that have infinite energy: in our example, nitrogen atoms are
equally likely to be at zero altitude as halfway to the Moon.
