Assuming that the universe is eternal, a question arises: How is it that thermodynamic equilibrium has not already been achieved? [4]This theoretical paradox is directed at the then-mainstream strand of belief in a classical view of a sempiternal universe, whereby its matter is postulated as everlasting and having always been recognisably the universe.
Hugh Everett did not mention quantum suicide or quantum immortality in writing; his work was intended as a solution to the paradoxes of quantum mechanics. Eugene Shikhovtsev's biography of Everett states that "Everett firmly believed that his many-worlds theory guaranteed him immortality: his consciousness, he argued, is bound at each branching to follow whatever path does not lead to death".

Space has fascinated humanity for centuries – from the mystery of the stars to the groundbreaking discoveries that push the boundaries of our understanding.
The first one to address the problem of an infinite number of stars and the resulting heat in the Cosmos was Cosmas Indicopleustes, a 6th-century Greek monk from Alexandria, who states in his Topographia Christiana: "The crystal-made sky sustains the heat of the Sun, the moon, and the infinite number of stars; otherwise, it would have been full of fire, and it could melt or set on fire."
Speculatively, it is possible that the universe may enter a second inflationary epoch, or assuming that the current vacuum state is a false vacuum, the vacuum may decay into a lower-energy state. [15]:§VE It is also possible that entropy production will cease and the universe will reach heat death. [15]:§VID
In a new book, molecular biologist Venki Ramakrishnan raises critical questions about the societal, political and ethical costs of attempts to live forever.
The anthropic principle states that this is an a posteriori necessity, because if life were impossible, no living entity would be there to observe it, and thus it would not be known. That is, it must be possible to observe some universe, and hence, the laws and constants of any such universe must accommodate that possibility.
But Kurzweil says one crucial step on the way to a potential 2045 singularity is the concept of immortality, possibly reached as soon as 2030. And the rapid rise of artificial intelligence is what ...
