According to the second law of thermodynamics, as an "isolated" system, the entropy of the universe will increase with time, from order to disorder. When the entropy of the universe reaches the maximum, all other effective energy in the universe has been converted into heat energy, and the temperature of all substances has reached thermal equilibrium. This state is called thermal silence.
In such a universe, there is no longer any energy to sustain movement or life. The theory of thermal death was first deduced by William Thomson in 1850 according to the thermodynamic principle of mechanical energy loss in nature.
2. Big Chill is a new theory of the formation of the universe put forward by theoretical physicists at the University of Melbourne, Australia, in August 20 12. The theory holds that the universe is formed in crystals that are constantly cooling.
A theoretical physicist at the University of Melbourne in Australia said that the best metaphor for the initial formation of the universe may be the process of water freezing. According to their theory, three dimensions of space and one dimension of time are formed by "freezing", and physicists suggest that we should be able to find "cracks in time and space" by looking for natural cracks in these ice crystal particles.
These physicists say that by studying tiny cracks in ordinary ice crystals, we will be able to revolutionize our previous understanding of the nature of the universe. James Quach, the chief scientist of the project, said that this theory is the latest effort in the long journey of human beings to explore the mysteries of the nature of the universe.

Development history
The theory of thermal death originated from physicists' research on the influence of the first and second laws of thermodynamics on the cosmic process in the19th century. Especially in 185 1, william thomson described a thermal experiment theory at that time as follows:
"Heat is not a substance, but a dynamic form of mechanical action. We realize that mechanical work and heat must be related, just like cause and effect. " Subsequently, hermann von helmholtz and William Rankin developed the theory of thermal silence.
