### JOINING post

Hi all, I am Georges QuĂ©not. I have a PhD in Computer Science. I have worked on computer architectures dedicated to speech recognition and image processing. I am now more on the software side and I am working in the field of Multimedia Information Retrieval. My main work is not so related to the

### Is the universe computable?

I start from a part of this post from David Barrett-Lennard (Mon, 3 Nov 2003 19:48:49) but I could probably hev selected several similar other ones: Given the source code for the simulation of our universe, it would seem to be possible to add some extra instructions that test for a certain

### Re: Is the universe computable?

Indeed, I've always thought there was a dubious assumption there. There isn't a universal time to pace the clock tics of a simulation. Relativity forbids it. Anyway, time is a subjective illusion. Back to the question: So what happens when the simulation diverges from regularity? Some

### Re: Is the universe computable?

It seems to me that there is a very strong assupmtion here which is that there should be some synchronicity between the time in the postulated computer into which the universe would be simulated and the time inside that simulated universe I have been studying the function of what I refer to

### Re: Is the universe computable?

I would be interested in reading the opinions of the participants about that point and about the sense that could be given to the question of what happens (in the simulated universe) in any non- synchronous simulation when the simulation diverges ? I would expect that the situation would
