How strong must a CPU be to simulate the universe?

That depends from the resolution of the simulation brainlet. I just simulated the whole universe with my android phone, in wich each galaxy was a bit.

Basically, you can't simulate a clone of a universe inside itself unless you zip away parts of it.

7.5

The CPU can be as shitty as you want it to be, the simulation will just run slower

How the fuck would you know? Have you ever tried? No? Then shut up you dumb bitch

atleast HRC 60 and 900 MPa tensile strength

I run your sex life on a pentium 2.

All you need to take into account is an observer perceiving such universe. Take yourself for example. All your life you believed that all the people around you are experiencing this universe the same way you do not knowing they are all just unaware dummies with no free will or consciousness that are made to behave similar way you do only because if you were to found out you are the only aware being in this universe you would certainly go mad. You are living in the matrix where all the natural laws are generated in a particular way to make it believable for you to go on with your life without going mad and killing yourself. I am your subconscious mind trying to wake you up from this nightmare you call living. Wake up!

Plank number as smallest resolution.

You could just run it 1000 times slower.

You'll need at least a GTX 1080 graphics card, maybe two

We can't simulate it unless we way a way to losslessly compress it. Is there a way? Probably not

25 THz speed with a 50 YB cache

Time is just an illusion created by our brains. The univserse has no speed of time

You can prove things mathematically without trying them. We aren't cavemen anymore.

What is the simulation brainlet and why does its resolution matter?

>Let us say it creates a new universe from quarks or whatever smallest particle is.
Completely inefficient. A baseball may microscopically consist of a shitload of quarks, but it behaves just like a macroscopic, massive ball, Newtonian that is. Modeling it as anything but that is a waste. Likewise for simulating large scale astronomical structures.
Hint: this is what our creators figured as well. To save on computational resources, you only introduce more detail as scales get smaller (classical => quantum => string theory). It's very similar to how distant objects such as trees in videogames consist of low res textures and no eye candy (you can barely see it anyway), then as you get closer to it, higher res textures load and effects such as shadows, animation or tesselation get applied.

You can simulate the entire multiverse using a single photon.

atleast stronger than itself.
if it aims to simulate the universe with itself in it.

deeeep

>>8942988
Wait...
What if we used...loss...to compress it?

>>8945886
No

You would need the entire universe. However, if it's simulated on a computer, than that universe can't be simulated because the computer is not part of the energy needed to simulate the computer. Ergo: we can't simulate our own universe, but we can simulate one. We've done it countless of times already.

You could do it with pencil and paper. Of course, you would need a lot of pencils and paper.

Does it have to be accurate? Any inaccuracy will spawn greater inaccuracy in subsequent states. The states themselves have to be infinitesimally close to each other in time as well. The order of events have to be precise or the simulation will break with reality. I don't think a true simulation is possible. The only "CPU" that can run reality is matter itself.
