You're absolutely right, Homo Sapiens will disappear much before the sun dies. In this post I wanted to talk about the interesting future of the sun and nearby planets. My intention was not to worry about it. As we know, it will happen so far in the future that there is no point in worrying about it. As you said, global warming is much more important issue right now, but as a topic it is not related to astronomy. It is more on environmental side. Pericles, interesting points. The universe (at least this one) is so huge that at least I believe there are other forms of life as well. Not necessarily humans like us, but may be bacteria or something else. I don't mean "green little men from Mars".. Pericles, you said the universe itself will seize to exist. This is an interesting field of discussion. Remember my post related to Friedmann's Three Assumptions? http://homeboyastronomy.com/2007/10/16/h/ According to Friedmann, the universe might exist "forever". Don't as how much is that :) Notice also that some folks claim that there is an infinite amount of parallel universes. http://homeboyastronomy.com/2008/02/03/black-hole-video-stephen-hawking-talking-about-black-holes-and-his-theory/ I gotta say the claim "infinite amount of parallel universes" is mindblowing. It really expands my thinking and makes ordinary dying people, like me, a bit confused. Ashlie, thanks for your comment. You’re absolutely right, Homo Sapiens will disappear much before the sun dies.

Not even the universe itself. It is most probable that Homo Sapiens will seize to exist long before. However, we are dreamers and we also like science fiction. There is also the possibility that we will survive, by colonising other stars and eventually the whole galaxy. Depending on Drake's equations parameters, there is a possibility that there is only one civilization per galaxy capable of achieving technology. Perhaps we are that civilization. Perhaps, even, we may be able to open parallel universes through black holes, if you believe some of he new theories. As Marko said, nothing lasts forever, not even the Sun.

I bet gloabal worming or buning holes in our ozone will kill us first. The sun is going to dy like everythinf else will, but their are more important things that might kill this generation before we have to worry about the generation that will be 5 billoin years later.

I agree with you, Alex. In this post I just wanted to discuss about the future of the Sun. I wrote about this some time ago.
