The End of Humanity

That's an interesting question....

2100 AD - Global warming.  (I think)

We're a plague and the only thing that will stop us is us. (Our own greed, consumption and waste, which are topics that are not that unrelated.)

Just ignore this answer and move on to the next. I'm so paranoid, I'm thankful to every living day. I have no idea how or when, but something tells me that it'll have something to do with greed.

Interesting topic, I wish I had time to read the website you link to. Care to share some of the views from the site? Anything pretecularly interesting?

Thanks TalSh, it sounds fascinating. I'll add these books to my list.

Kurzweil is god.

(or damn close to it)

(..made great synths, too!) 

Space and time I can not tell ( Mathematians can't you use Einstein formulas?). As for the cause "KNOWLEDGE"! I think in many ways human beings are slowly exterminating themselves

Life, in its most absolute sense, can never end. It is what we make it to be. Time is simply a finite human belief and not a principle of the universe itself. Life is God and we are God's ideas. It's up to us to improve our thoughts and thus our lives and this can only be done through spiritual growth and understanding. Our humanity will improve as our ability to love improves.
