Physicists find we’re not living in a computer simulation

[HR][/HR]
Some physical phenomena may be impossible to simulate.

Just in case it’s been weighing on your mind, you can relax now. A team of theoretical physicists from Oxford University in the UK has shown that life and reality cannot be merely simulations generated by a massive extraterrestrial computer.

The finding – an unexpectedly definite one – arose from the discovery of a novel link between gravitational anomalies and computational complexity.

In a paper published in the journal Science Advances, Zohar Ringel and Dmitry Kovrizhi show that constructing a computer simulation of a particular quantum phenomenon that occurs in metals is impossible – not just practically, but in principle.

The pair initially set out to see whether it was possible to use a technique known as quantum Monte Carlo to study the quantum Hall effect – a phenomenon in physical systems that exhibit strong magnetic fields and very low temperatures, and manifests as an energy current that runs across the temperature gradient. The phenomenon indicates an anomaly in the underlying space-time geometry.

Quantum Monte Carlo methods use random sampling to analyse many-body quantum problems where the equations involved cannot be solved directly.

Ringel and Kovrizhi showed that attempts to use quantum Monte Carlo to model systems exhibiting anomalies, such as the quantum Hall effect, will always become unworkable.

They discovered that the complexity of the simulation increased exponentially with the number of particles being simulated.

If the complexity grew linearly with the number of particles being simulated, then doubling the number of partices would mean doubling the computing power required. If, however, the complexity grows on an exponential scale – where the amount of computing power has to double every time a single particle is added – then the task quickly becomes impossible.

The researchers calculated that just storing information about a couple of hundred electrons would require a computer memory that would physically require more atoms than exist in the universe.

The researchers note that there are a number of other known quantum interactions for which predictive algorithms have not yet been found. They suggest that for some of these they may in fact never be found.

And given the physically impossible amount of computer grunt needed to store information for just one member of this subset, fears that we might be unknowingly living in some vast version of The Matrix can now be put to rest.

your tax dollars hard at work
if only these ''scientists'' would put half that effort into curing disease

Yeah, I would like my deafness cured. They predicted, that cure in 20 years. Too bad they are thinking about conspiracies instead. At least it's entertaining to see their ideas failing in real life.

I don't think that is really able to penetrate through the near-theological level of immunity of the simulation hypothesis. You are making assumptions about their level of mathematical understanding - that they don't have better models with which to undercut complexity - assumptions about how their computation would work - that it doesn't use some form of quantum computing - and that our own simulation would be an accurate representation of the laws that govern their universe rather than some abstract artist joke - as far as we know our universe could be as accurate of a representation of theirs as Pacman is of ours, "all the matter in our universe" could be absolutely nothing for them, arguably it has to be if you are going to run enough simulations for the probability principle behind the simulation hypothesis to take hold.

Now if you excuse me...

You're assuming that physicists are equipped to cure disease. They're physicists not Biomedical specialists.

Secondly not everything learned needs to be immediately practical. This research could have useful far-reaching implications that we can't foresee as of yet.

I was actually thinking along those lines, their logic is flawed even though I suspect they're correct in substance.

That is my intuition as well, though then again, if I was programing a simulation and wanted NPCs to reject and dismiss the simulation hypothesis, that is exactly what I would program into their intuition :laughing:

Right? Who wants the characters to know they're in the story........it seems propable that they'd find some way to reject even obvious evidence that challenges their worldview.

And just in case the idea still comes through, let's add a near instinctive worship reaction to the idea of higher beings that control their universe.

no, where the fuck did you get that from?

really, well I'll be
thank's for the info Einstein :dry:

yes I agree
maybe they can next prove all of mankind is not living in some one else's shared dream:frustrating:

As long as you cannot escape the said simulation it doesn't matter if you live in a simulation. The entire universe could be a simulation with the main four forces of nature set to a certain level. By the four forces I mean gravity, electromagnetism, weak and strong forces, not "fire, water, earth air" stupid bullshit.

You were the one who equated the physicists with the med specialists under the moniker "scientists". Just wanted to help you draw the distinction lad.

Oh my, I can finally sleep soundly.

But it would have added some excitement to my otherwise mundane existence...

What if the simulation-computer thought that they might try see if they were in a simulation by using this method, so it created the anomaly within gravity and math so that they would 'prove' that the simulation does not exist, therefore the secret remains safe.
