Are we living in a simulation?
Whilst randomly surfing I came across this site, basically it's a link site to a series of papers investigating the question of whether what we currently perceive as reality is really just a simulation of the past being run by some future entity. Obviously The Matrix was the biggest popular look at this but it is a fascinating (though by it's nature, unanswerable) question. Certainly gives the whole 'creation' argument a new spin...wikipedia entry here.
"In the beginning God created the heaven and the earth
And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
And God said, Let there be light; and there was light.
And God saw the light, that it was good: and God divided the light from the darkness."
-- Genesis 1: 1-4 (KJV)
What if what 'God said' was a whole bunch of code :-)
I am a believer in something called 'The Technological Singularity' and I recently finished a great book on the subject called 'The Singularity Is Near' by Ray Kurzweil. One of the really interesting things in this book is the notion that if we survive for another 25-30 years, technology will have advanced to the point where we can essentially live forever...quite compelling!
Anyway, just another of the bizarre notions which floats around in my mind, what better way to explain the universe than it being a man(or post-human)-made simulation...
