That is all true, but irrelevant to the (false) claim that FTL motion would be required to exceed the Planck temperature.hilbert2 said:The object would have to contain enough particles for a thermodynamic temperature to be sensible to define, which sets a lower limit for heat capacity. Then there's a limit for how much energy you can even in principle gather from the surrounding universe to heat that up.
PAllen said:It may well be that at Planck temperature known physics is suspect, but there is absolutely no basis to say particles would have to travel faster than c to exceed that temperature. There is no upper bound on kinetic energy, therefore temperature. What is true is that collisions in such a gas would exhibit new physics.
Kenneth Watman said:My view remains the same. So far as we can tell based on the latest physics, the limit is the Plank Temperature
Kenneth Watman said:As the Big Bang remains somewhat controversial
Is it possible your belief in a relation between needing faster than c relative motion to exceed the Planck temperature is based on believing Newtonian kinetic energy is correct except for some 'correction' for SR?Kenneth Watman said:...
The last possible answer, #5, is that offered by PAllen copied below. The fundamental problem with his critique is that if K=1/2 mv^2 or
The maximum temperature that something can reach is known as the absolute hot or Planck temperature, which is approximately 1.416 x 10^32 Kelvin. This temperature is theorized to be the highest possible temperature that can exist in the universe.
The limit to how hot something can get is based on the laws of thermodynamics, specifically the third law. This law states that it is impossible to reach absolute zero (0 Kelvin) through a finite number of steps, and therefore, it is also impossible to reach the absolute hot temperature through a finite number of steps.
According to current scientific understanding, it is impossible for anything to reach the absolute hot temperature. As an object's temperature increases, its energy also increases, and at the absolute hot temperature, an object would have an infinite amount of energy, which is not possible.
Yes, there is a practical limit to how hot something can get. This limit is based on the physical properties of the material and its ability to withstand high temperatures without melting or breaking down. For example, the melting point of tungsten, one of the highest melting point elements, is approximately 3695 Kelvin, which is much lower than the absolute hot temperature.
According to current scientific understanding, the absolute hot temperature is a constant and does not change. However, some theories, such as string theory, suggest that the absolute hot temperature may have been different in the early universe. This is still a topic of ongoing research and debate.
