The Measurement That Would Reveal The Universe As A Computer Simulation
If the cosmos is a numerical simulation, there ought to be clues in the spectrum of high energy cosmic rays, say theorists

It's not hard to imagine that Moore's Law-type progress will allow physicists to simulate significantly larger regions of space. A region just a few micrometres across could encapsulate the entire workings of a human cell.

Again, the behaviour of this human cell would be indistinguishable from the real thing.

It's this kind of thinking that forces physicists to consider the possibility that our entire cosmos could be running on a vastly powerful computer. If so, is there any way we could ever know?

Today, we get an answer of sorts from Silas Beane, at the University of Bonn in Germany, and a few pals. They say there is a way to see evidence that we are being simulated, at least in certain scenarios.

First, some background. The problem with all simulations is that the laws of physics, which appear continuous, have to be superimposed onto a discrete three dimensional lattice which advances in steps of time.

The question that Beane and co ask is whether the lattice spacing imposes any kind of limitation on the physical processes we see in the universe. They examine, in particular, high energy processes, which probe smaller regions of space as they get more energetic

What they find is interesting. They say that the lattice spacing imposes a fundamental limit on the energy that particles can have. That's because nothing can exist that is smaller than the lattice itself.

So if our cosmos is merely a simulation, there ought to be a cut off in the spectrum of high energy particles.

It turns out there is exactly this kind of cut off in the energy of cosmic ray particles, a limit known as the Greisen–Zatsepin–Kuzmin or GZK cut off.

High Energy Physics - Phenomenology
Constraints on the Universe as a Numerical Simulation

Silas R. Beane, Zohreh Davoudi, Martin J. Savage
(Submitted on 4 Oct 2012)
Observable consequences of the hypothesis that the observed universe is a numerical simulation performed on a cubic space-time lattice or grid are explored. The simulation scenario is first motivated by extrapolating current trends in computational resource requirements for lattice QCD into the future. Using the historical development of lattice gauge theory technology as a guide, we assume that our universe is an early numerical simulation with unimproved Wilson fermion discretization and investigate potentially-observable consequences. Among the observables that are considered are the muon g-2 and the current differences between determinations of alpha, but the most stringent bound on the inverse lattice spacing of the universe, b^(-1) >~ 10^(11) GeV, is derived from the high-energy cut off of the cosmic ray spectrum. The numerical simulation scenario could reveal itself in the distributions of the highest energy cosmic rays exhibiting a degree of rotational symmetry breaking that reflects the structure of the underlying lattice.

Well crap....thanks Pink Cat for screwing up my paradigm.

Good catch +5

Of course it is, and it was created just for me. None of you are real in the least. All bots. The designer likes throwing these hints at me.

Sounds like some flawed logic to me.

Simulation implies copy. Copy implies original. Original implies unique.

Great work op !! So does this mean that we are truly in the Matrix?
It sure has seemed like this to me for many years... Ever since I watched the movie with Jim carry .. Crap!! Forget the name 😗

it's freaky to think about. makes sense to me, tho

The Truman Show...

But anyway, who cares, we are a simulation. Yay. Now can we all get over ourselves and start going against the code?

I think this universe at this frequency range is a game construct, and we are the avatars of the players from a different dimension. You of course come into the game construct with no knowledge that you are in a game construct, because if you had that knowledge it would alter the game. You take the game seriously, because you believe it is your true existance, this also gives the game meaning.

But things like prophecy, ESP, intuition, are all things that should be impossible and are unable to be explained by science, yet they obviously occur. These are subconcious manifestations of our true selves. Knowlege of how and where the game programming is progressing too, etc.

We find numerous clues to this in our subconcious and our dreams, but we desperately want to believe it's real, so we ignore these clues....

well said

Yhe God machine (god as a computer) being pushed by TPTB soon tm

As usual, dont get deceived...

you are an amazing simulation, you just need updating alittle that is all.

Say It ain't so!!!!!....



PARANOMIA

Wow.. Very well said ... And nice and simply without twisting my brain :):clappa:

bumpity bump

zippity zap

*waits for "Russian Scientists" to confirm*


------

I don't know about a simulation, but God did determine all things from beginning to end, and everything moves in its perfect order and purpose, according to his Will (i.e. Program). He is the great Scientist, Mathematician, etc....

They will never figure this out if they don't belong to Him.

duh

I have the exact same feeling my whole life. Weird isn't it

Thread: did anyone else see a floating hexagonal grid formation waving around in your room as a child?
