One step closer to creating ourselves: Simulation Creates First Realistic Virtual Universe

[QUOTE=NixNax123;44760703]We will never be able to make a simulation of our entire universe down to the atomic level.
Let's say a computer needed 2 atoms of space (highly likely more, but I'm going to extremes just to please the "but what if new technology" people) to process a single atom.
Then, if we wanted to even simulate our world down to the atom, we would need a computer much bigger than Earth. So that won't ever happen for the earth, let alone our universe.[/QUOTE]
but what if new technology
[QUOTE=Hardsurface;44759308]Not sure on the legitimacy of this to be honest.

Agreed. I do Ecological simulation, and even simulating something as relatively small and simple as an ecosystem (compared to the scale and complexity of the universe) is nigh impossible. We make sacrifices at every corner because we don't know everything that affects that system, so it is only ever a model, rather than a direct representation of reality.
So... I'm calling bullshit on the Escapist interpretation without more sources to back it up. What I suspect they've done is they've modelled an approximation of the Universe.
[QUOTE=Shreddinger;44762076]did you read the article?[/QUOTE]
[i]No, I just looked at the link and took a wild guess.[/i] Of course, I read it.

I especially found the plot twist at the end to be the most entertaining.

Shitstick of an article, I am sorry.
[QUOTE=Riller;44760996]To be precise, we'd need a computer twice the size of Earth to simulate Earth alone, in that case. To simulate the entire universe, we'd need twice the amount of matter available in the entire universe.[/QUOTE]
Now we know where all the matter went when it collided with antimatter, someone needed materials.

This used to be the case until quantum computers arrived. Just 100 qubits can store 2^100 data states. Let one state represent an atom. Problem solved!

[QUOTE=zakedodead;44761390]Other than the fact that even if we are in a simulation, that's completely unfalsifiable and wouldn't really make any difference to us because [B]there is no way to prove/disprove it.[/B][/QUOTE]
Yes there potentially is and experiments have been done to try and expose it.

It's published in Nature.

[QUOTE=KD007;44761966]It must not be a full simulation. Otherwise, information paradox.
That article [i]maybe[/i] disproves that our [i]ancestors[/i] are running us as a simulation. Still, nothing disproves that we are being simulated by a complex, n>4 dimensional being (or multiple thereof). In fact, I personally find it very likely. Maybe not a classic grey-alien-looking thing, but something bizarre.[/QUOTE]
Would it not be funny if God turned out to be the equivalent of a child playing a videogame.

Yeah, I intend to see if my boss has it so I can read what the paper actually says, and not what the Escapist appears to want it to say.
