Researchers in [[futures studies]] and [[transhumanists]] investigate how the accelerating rate of scientific progress may lead to a "[[technological singularity]]" in the future that would profoundly and unpredictably change the course of human history, and result in ''Homo sapiens'' no longer being the dominant life form on Earth.<ref name="agi-conf">[[Anders Sandberg|Sandberg, Anders]].

Occasionally the term "physical eschatology" is applied to the long-term predictions of astrophysics about the [[future of Earth]] and [[ultimate fate of the universe]].<ref>Ćirković, Milan M.

Life on Earth will become impossible due to a rise in temperature long before the planet is possibly actually swallowed up by the Sun or left charred.<ref name="zeilik">{{Cite book |last1=Zeilik |first1=M.A. |last2=Gregory |first2=S.A.|title=Introductory Astronomy & Astrophysics |edition=4th |page=322 |publisher=Saunders College Publishing |year=1998 |isbn=0-03-006228-4}}</ref> Even later, the Sun will become a [[white dwarf]].
