According to Reed Richards, the ultimate fate of the Multiverse is to perish in an all-encompassing heat death. Source: Internet
It has been speculated, since the 19th century, that the universe is fated to a heat death in which all the energy ends up as a homogeneous distribution of thermal energy, so that no more work can be extracted from any source. Source: Internet
Hermann von Helmholtz puts forward the idea of the heat death of the universe in 1854, the same year that Clausius established the importance of dQ/T ( Clausius's theorem ) (though he did not yet name the quantity). Source: Internet
Recent work has cast some doubt on the heat death hypothesis and the applicability of any simple thermodynamic model to the universe in general. Source: Internet
Sharlin (1979) p.169 He contended that the laws of thermodynamics operated from the birth of the universe and envisaged a dynamic process that saw the organisation and evolution of the solar system and other structures, followed by a gradual "heat death". Source: Internet
This introduces an instability, a feedback loop that pushes the hidden variables out of "sub-quantal heat death". Source: Internet
