Digital physics[edit]
OverviewDigital physics suggests that there exists, at least in principle, a program for a universal computer which computes the evolution of the universe. The computer could be, for example, a huge cellular automaton (Zuse 1967[9]), or a universal Turing machine, as suggested by Schmidhuber (1997), who pointed out that there exists a very short program that can compute all possible computable universes in an asymptotically optimal way.
Some try to identify single physical particles with simple bits. For example, if one particle, such as an electron, is switching from one quantum state to another, it may be the same as if a bit is changed from one value (0, say) to the other (1). A single bit suffices to describe a single quantum switch of a given particle. As the universe appears to be composed of elementary particles whose behavior can be completely described by the quantum switches they undergo, that implies that the universe as a whole can be described by bits. Every state is information, and every change of state is a change in information (requiring the manipulation of one or more bits). Setting aside dark matter and dark energy, which are poorly understood at present, the known universe consists of about 1080 protons and the same number of electrons. Hence, the universe could be simulated by a computer capable of storing and manipulating about 1090 bits. If such a simulation is indeed the case, then hypercomputation would be impossible.
Loop quantum gravity could lend support to digital physics, in that it assumes space-time is quantized. Paola Zizzi has formulated a realization of this concept in what has come to be called "computational loop quantum gravity", or CLQG.[10][11] Other theories that combine aspects of digital physics with loop quantum gravity are those of Marzuoli and Rasetti[12][13] and Girelli and Livine.[14]

no other possible way im afraid, if were non digital, then we evolved, and until someone can prove we are non digital nobody can say we definatly evolved..

What the hell...? No dude, that is not how it works. YOU prove we are digital. Not the other way around.
And, also, yes we can say we evolved. There is so mush evidence that we did that any argument against it is little more than a grasping at straws.
Dogs respond to and understand a limited vocabulary, wolves do not.. Dogs have evolved to take various different shapes and behaviors based on what we wanted from them. The list goes on and on.
This is just ONE TINY example of provable evolution. There are millions of others around the planet.
we got here from an explosion

Until you can provide it, and it can be independently verified, you are operating on ASSUMPTION.
You ASSume that if we were created we would be digital beings.
It could go the other way too. You are saying that beings created by a creator would be digital. That if it were shown that we are "digital beings" (whatever that means) that it would prove the existence of God. Your assumption is based on the fact that we humans have created digital forms of being. (Not intelligent life.)
So yeah, could it be said that we MUST follow the rules of nature, which evolution also followed, in our technologies? To put it another way; Assuming we are "digital beings" it would not be proof of a creator. It would only be proof that we must copy nature in our technology.
Your argument is... Well it's the kind of argument you'd expect from a religious person. Illogical, without science backing it up, based on personal beliefs and not observable reality.
I'm not saying your ideas are definitely wrong, just that your method of reaching them is.
you really don't understand what I'm saying, I'm not religous, this argument is completly logical
if we were created then that would mean that the universe is digital (i.e. a computer) and we would be a digital being within the computer. I can't accept theorys that a computer formed on its own, someone would have had to have created that computer (real life) therefore if we are digital, then that means we were created..
nobody has proven that this universe we live in is not a computer, and that is the only way to conclusively prove that we evolved. Because if the universe is not a computer then we evolved! Yet science hasn't touched on this fact at all, instead its been looking in all the places to prove we evolved.
I'm really not trying to get your back up, its fact
Its perfectly possible for us to be a digital being! in fact more likely mathematically that we are digital than we evolved!
having to reply to a lot of people here but,, it works both ways.. either a scientist needs to disprove we are not digital, or a scienctist needs to prove we are digital

well in effect our species may well be digital. i.e. we are not a real being, we are a simulated digital being.
and again I'm saying which is fact, its more likely that we exist because a species created a computer, which we see as this universe, than we got here from an explosion...

although i hate to turn to religion to prove this point, the fact is i can't prove we are digital, but the fact is nobody yet has managed to prove we are not digital and therefore nobody can say that we are here as a result of an explosion, nor can a creationist say we were definately created..

No one has proven the universe we live in is not an orange... however i doubt we are in a giant orange....
i understand where you are comming from but the problem still then is... if the universe we live is a computer, and we are digital beings, who wrote the programming, then is someone that wrote our programming in a digital world too, meaning we are a creation of a creation, even if the being who created our digital world is a non-digital entity, how was it formed, by evolution? if so then we would then be infact also a product of evolution, think of a standard biege apple 1 pc to the swankiest new iphone, that although creation was an evolution of trial and error to become the super mini computer thing we have today?
the problem with Digital beings thought is this... you then believe the being created us, evolved, was created by another being or has always exsisted, the problem still then lies of which is correct in terms of the progression of life in any universe.
and please could someone provide a link of evidence that we evolved? because as far as I can see, there is only circumstantial evidence, there is nothing conclusive that we evolved at all..

Again, why not both? If our universe is a computer simulation, it does not make evolution or big bang any less valid. They simply happened in the simulation, too.
