simple answer, if the temperature really drops to minus 273 degrees below absolute zero, time will stop. And it is by no means as simple as time stops, there are even more terrible things happening.
First of all, we need to understand what the temperature is. Simply put, temperature is the thermal motion of molecules, and the definition of absolute zero is the lowest temperature on thermodynamics , which is the temperature when all microscopic particles stop moving, that is, kinetic energy is zero. So a temperature lower than absolute zero does not exist.
So can it reach absolute zero?
does not. According to the uncertainty principle of , the product of the velocity and position uncertainty of microscopic particles must not be less than a constant, that is, the velocity uncertainty of microscopic particles cannot be zero. If it is zero, the velocity is determined, which violates quantum mechanics.
Therefore, it is impossible for microscopic particles to remain completely still, and the temperature cannot reach absolute zero.
temperature cannot reach absolute zero, just like our speed cannot reach the speed of light, it can only be infinitely close and cannot reach it.
can also be understood in this way. Absolute zero means that everything is absolutely still, everything is still, and even the time and space where we are, completely frozen, and time loses its meaning.
From a microscopic perspective, if electrons, protons and other microscopic particles are stationary, it means that atom will collapse, and everything is composed of atoms, which means that everything cannot exist.
In the end, there is only the empty universe left. Even the universe will not exist, because space and matter coexist with each other, and without matter there will be no space.
It can be seen that absolute zero is an ideal value. The temperature limit value calculated by mathematical formulas can only approach the entire temperature, and it will never reach this temperature.
Scientists have also conducted minimum temperature experiments in the laboratory to see how low the temperature can be created and whether it can reach absolute zero.
results show that no matter how hard the scientists work, the temperature created cannot reach absolute zero. The lowest temperature created by humans is infinitely close to absolute zero, only 0.5 nanometers higher than absolute zero. One opening ( Kelvin ) is equal to one degree Celsius, and one nanometer is equal to one billionth of a billionth. The 0.5 nm open is only one in a 2 billionth degree.
It can be seen that the temperature created by humans is approaching absolute zero infinitely, which is just a little short of it. It seems that the distance between absolute zero is close, but that is a gap that we can never break through!
