Since I think that mankind's destiny transcends the destiny of
the solar system, the sun's end may not mean the extinction of
mankind.


Destiny is a little fatalistic for my tastes :-) But logic would seem
to dictate that if human civilization survives even 50% of the time
remaining before the Sun becomes a problem then the technology to live
elsewhere, or even repair the Sun (we are after all a nostalgic bunch)
should be available :-)



It always amuses me when people believe that human civilization will
still be around several billions of years into the future....

Think back a billion years.  Life on Earth was then very primitive -
this was well before the cambrian explosion of life.  A lot has
happened in the evolution of life on Earth since the, right?  Man-like
animals have been around for only a few million years, modern man has
been around for only some hundreds of thousands of years, and human
civilization has been around for only a few thousand years.  So why do
you believe evolution will stop now, so mankind will be around several
billions of years into the future?  Are we slowing evolution down?  No
way!  Instead, we're rather speeding it up with our technological
advances, which now are influencing the Earth also on a global scale.
Our artificial breeding of both plants and animals also speeds up
evolution a lot.

In a way I like that very long-term perspective though, and it would
indeed be nice if such a long-term perspective gained wide acceptance
within mankind.  We would certainly deal with e.g. the global warming
issue in a quite different way if we really considered billions of
years of future, rather than at most a few decades of future....

Anyway, mankind will definitely be gone since a very long time a
few billions of years into the future.  Either we will be extinct, or
else we will have evolved into something else.  And there may of course
be more than one future branch of evolution from present-day mankind.


That was my point in referring to "mankinds heirs".

It is possible that carbon-based life will give way to silicon-based
life, which will not depend on biology as we understand it.  This
form of life could be much better adapted to living in a vacuum,
for example.

Is is, of course, possible that the human species will either be
extinguished or will extinguish itself before achieving sufficient
dispersion to survive catastrophies.  At this point, the probability
of that seems non-negligible.

But it is also possible that we will transform ourselves--being now
the prime movers of evolution--into creatures more adapted to the
diverse future that we will inhabit.  Some of these forms may continue
to have biology similar to our current form, but it seems likely that
other forms will also exist.

How much of current knowledge (likely) and culture (less likely)
persists in future ages depends on how much discontinuity occurs,
and along which branches of our future evolution.

One can hope that our future branches would coexist, and perhaps even
cooperate, but that is far from certain, depending on how we deal with
competition.

The intelligence of humanity is an activity that can grow and spread
as long as there is a suitable substrate, just as a fire spreads as
long as there is heatable fuel and oxidizer.

Unlike fire, intelligence can alter the basis of its substrate, and so
can spread more widely, given time, motivation, and energy.
