It'sIts theorized value is ~ $$1.416 \cdot 10^{32}$$ Kelvin. Above this temperature, it would be impossible to pump more energy into a system, even gravitationally. That gives an upper bound on the maximum temperature we could measure. Note that while we haven't observed anything even close there is a theorized Absolute Hot along the lines of absolute zero.
