Quanto ci resta da vivere?

No, Non noi singole persone ma più in generale la razza umana.

10.000 ? 100.000? un milione di anni?  o forse 3 miliardi( più o meno quando il sole deciderà di farci fritti)?

Secondo alcuni docenti di filosofia anglosassoni 10.000 è il termine più probabile.

Molto spassosa per noi Umaniaci la lista delle possibili cause di estizione.

Vedi la seguente citazione:

Planet Earth will be scorched
by the dying sun in about 4 billion years, and Mars too will become uninhabitable by organisms
such as we are now. If humanity is to survive beyond this period, it will have to have
reestablished itself somewhere in the outer solar system or in another solar system. It is very
unlikely that such resettlement can occur without major modifications of the human organism
having first been made. It won’t do to try to resettle first and then adapt–the rigors of other
environments are far too great. But we cannot count on having as much as 3 billion years to
engineer this transition. In fact, we live in perpetual danger of extinction due to any one of or
combination of the following:

Threats
• plagues and epidemics
• warfare
• famines
• ecological disasters, e.g., runaway global warming or cooling
• “hostile” AI
• mass suicide
• mass voluntary infertility
• “gray goo” from accidental or calculated release of malign nanoassemblers
• catastrophic impacts of near-Earth ob<x>jects (“NEOs”) or comets
• gamma-ray bursts
• black holes
• supernovae
• collapse of the vacuum-energy state, and other outré disasters
• attack or inadvertent destruction by alien organisms
• other, as yet unknown

To this list one further threat perhaps should be added, namely: misguided attempts to avoid the
above. The subject deserves a much more thorough discussion (Bostrom 2002; Rees 2003) but it
is not unreasonable to suppose that these hazards reduce the life expectancy for humanity as we
know it to about 10,000 years.

Per chi volesse approfondire metto un link ad un interessante ( anche se un po accademico ) articolo di Nick Bostrom

Io comunque tra tutte le ipotesi voto : black holes
