Simulation Suggests 68 Percent of the Universe May Not Actually Exist (newatlas.com)
boley1 quotes a report from New Atlas: According to the Lambda Cold Dark Matter (Lambda-CDM) model, which is the current accepted standard for how the universe began and evolved, the ordinary matter we encounter every day only makes up around five percent of the universe's density, with dark matter comprising 27 percent, and the remaining 68 percent made up of dark energy, a so-far theoretical force driving the expansion of the universe. A new study has questioned whether dark energy exists at all, citing computer simulations that found that by accounting for the changing structure of the cosmos, the gap in the theory, which dark energy was proposed to fill, vanishes. According to the new study from Eotvos Lorand University in Hungary and the University of Hawaii, the discrepancy that dark energy was "invented" to fill might have arisen from the parts of the theory that were glossed over for the sake of simplicity. The researchers set up a computer simulation of how the universe formed, based on its large-scale structure. That structure apparently takes the form of "foam," where galaxies are found on the thin walls of each bubble, but large pockets in the middle are mostly devoid of both normal and dark matter. The team simulated how gravity would affect matter in this structure and found that, rather than the universe expanding in a smooth, uniform manner, different parts of it would expand at different rates. Importantly, though, the overall average rate of expansion is still consistent with observations, and points to accelerated expansion. The end result is what the team calls the Avera model. If the research stands up to scrutiny, it could change the direction of the study of physics away from chasing the ghost of dark energy. "The theory of general relativity is fundamental in understanding the way the universe evolves," says Dr Laszlo Dobos, co-author of the new paper. "We do not question its validity; we question the validity of the approximate solutions. Our findings rely on a mathematical conjecture which permits the differential expansion of space, consistent with general relativity, and they show how the formation of complex structures of matter affects the expansion. These issues were previously swept under the rug but taking them into account can explain the acceleration without the need for dark energy." The study has been published in the Monthly Notices of the Royal Astronomical Society. You can view an animation that compares the different models here.
Simulation this and simulation that. All based on guesswork and a very questionable understanding of this reality. Obviously the "simulation" is junk if it comes up with stupid numbers. In fact, I don't see how it could ever be possible for us, fishes in an aquarium if you will, to understand the "outer reality" which supposedly created our universe. Like the "Big Bang"... yeah. Zzz... very boring stuff. It doesn't matter in the least bit unless we know what happened *prior* to the "Big Bang". That's the interesting (and unknowable) part.
then i remembered what day it was. ughghg
That is new for an April Fool's prank :D
It seems the sims are running simulations in my simulated universe.
- The creator.
This was published March 30, 2017 so it's not a April fools joke.
Suck it, dark matter! You ain't real, bro! *High-fives girlfriend* Aww, she's not real either. ;(
Anons need not reply. Questions end with a question mark.

Nah, it is the Zigerions. They nest 3 simulations just to be extra safe. And still fail.
Instead of blaming the flawed simulation, the unbelievably arrogant "scientists" behind this decided that 68% of the universe does not exist.
Would chhose to use there are about 700 may also want
...really doesn't have a heart, just like I suspected? Not that I'm bitter or anything.
Why does everyone think it is hilarious to post bullshit on April Fools Day?
I was frantically trying to get my young daughter to a Hospital and accidentally hit the "Game" icon in Google Maps.
Anyway, it worked out well, my daughter died, and I am saving at least $5,000 to $10,000 a year!
Thanks Google!

Can you make it brighter, so it makes my eyeballs bleed?
thank goodness its april 1st, I was just heading back to soylentnews.org
If the expansion of the universe is not consistent, what causes the variation?
Anybody who understands science and the scientific method, and isn't just an acolyte of the One True Religion of Science, must have surely seen something like this coming. Think about the reasoning:
1. Our mathematical models of the vast and ancient universe, invented by us bald apes that are lucky to live a century, do not fully agree with observation.
2. Therefore, to account for this discrepancy, the universe must consist primarily of unknown, invisible substances whose only interaction with our visible universe just so happens to cause precisely the behavior you would expect if our models were completely accurate.
In software engineering, this is known as "wishful thinking", like when we swap out hardware and say "this hardware performs the same function, surely the drivers cannot be that different."
The difference between software engineering and physics is that software engineers can use the compiler and debugger to verify their wishful thinking is fantasy, whereas physicists must often come to this conclusion through a pure application of the intellect (or, more often, never at all; it is easier to shout down the unbelievers when they can't easily prove you wrong).
There didn't seem to be enough matter to explain the evolution of the universe, so scientists guessed at what might be causing it. It looked like there was more matter that we couldn't see, so they invented the idea of 'dark matter', which was something that had mass but was otherwise pretty inert so we didn't see it. BTW: 'dark' here is an old use meaning 'unable to be seen', such as 'the dark side of the moon' being the side that faces away from earth, not the side that is not lit by the sun. The other possibility was that gravity was somehow slightly different when operating over very large distances and times. This was settled because astronomers got better at calculating the distributions of mass in the universe when they thought there was something interesting to find, and found there were cases, such as the 'bullet nebula' where there were very significant amounts of mass in different places to the star-like matter we could see. This gives credence to the idea that 'dark matter' is a real sort of 'stuff', our can be treated as a sort of stuff, rather than just an systematic difference in the equations.
Okay, suppose we assume for now there is lots of invisible stuff that has mass and momentum, but otherwise does not interact with anything else much (think of neutrinos, but more so). If we take our best assumptions as to the right amount of dark matter, then there is a slight error which means something else is pushing the universe apart. If it looks like extra energy, we call it 'dark energy' and astronomers start looking for ways to detect it. In the meanwhile, other people look for a rival model where there is a systematic error in the equations for very large distances and times. That's pretty much where we are now. Indeed, the two explanations are not different - one just describes the error as 'extra energy' and the other one does not - until we get some new experimental evidence that shows which explanation is more useful.
Dark energy is a small correction term to our universe. If you want something we really don't understand, try the inflationary period of the early universe. We know it got really big, really fast, but really evenly; but we don't have any of the details.
Trump's supporters aren't dark. They dislike negros and Mexicans. Republicans use white racism to get whites to vote against their own economic interests. Trump voters are tools.
Trump is a stupid little bitch. Just like his ignorant supporters.
Or to be very specific, 68% of the researchers doing This Particular Study do not exist. That means the ones that DO just got a raise!
Sounds like fraud to me. Call the Science Police!
If the universe is someone's simulation -- does that mean the stars are just stuck pixels?
The correlation between two entangled particles is based on information stored within each particle at its creation. Entangled particles do not communicate with each other after they are created, so separation distance is not an issue.
A classical example: Take a pair of shoes and send the left and right shoes separately to two distant friends, Alice and Bob, without recording which friend got which shoe. You don't know who got which shoe, but you do know that one friend got the left shoe and the other friend got the right shoe. This is the essence of quantum-mechanical entanglement.
Alice eventually receives her shoe. Upon looking at her shoe, Alice sees that she has the right shoe, and instantly knows that Bob received the left shoe, without any communication from Bob.
Then 68% of my fat ass may not exist either.
Still better than news here!
"New Simulation Suggests 68 Percent of the Universe incorrectly evaluated by previous simulation / model."
The study showed that the "Dark" energy is not necessary to explain the expansion of the universe. Since they have never "proved" it existed, how can it "disappear"?
If this is true, then I just lost 145 pounds. Yipee!!!
Dear Microlimp: I give you 2 valid product keys for win7 and you reject both of them. Piss off you wankers!!!
Regardless of conflicting theories, Dark Energy will live on. This is for two reasons: 1- Dark Energy is rather essential to some science fiction fantasy; and 2- Dark Energy is not copyrighted by Disney or any other litigious entity. Try using 'the Force', 'the Spice Melange', 'Sonic Screwdriver' or 'the One Ring' to explain your scifi miracles and legal problems arise.
And, hey, It's Dark, and it's Energy; what's not to like?
...omphaloskepsis often...
I sure hope we're part of the other 32 percent.
That is one of the dumbest things I've read. If that's literally all the research you've bothered to do into the phenomenon, you're a complete retard to even begin to have an opinion on it. Your "lead scientist" was clearly has also not done any astrophysics.
Those who advocate genocide deserve every protection afforded by law, and none afforded by common human decency.
If it doesn't exist, then by definition it's not part of the universe.
Better title. Researchers estimate the mass of the Universe be be 32% of the previous consensus models.
Subject development needs open-minds
ignorance and Super-imposition does not help - rather it damages spirit of science.
why not create East-west Interaction.
cosmic function of the Universe helps in time- for prime concepts.

Musk is apparently convinced everything is just a simulation. He seems to be right about sooooo much... he could be right. I'm just a figment of his imagination.
Even God has deficit problems.

As I interpret this, they really did "assume a spherical cow" at first.
The old models assumed uniform expansion of the universe (a 4D sphere) because apparently that either makes the math easier, or we didn't have the computing power back then to "do it right". But that required "dark energy" to explain some oddities we observe in the current universe.
Then these guys looked at expansion rates and patterns with lumpy matter (uneven aggregation), found it made a big difference, and now we allegedly don't need "dark energy" to explain current observations anymore.
Thus, they simulated with a more realistic cow shape instead of with a spherical cow, and got results that fit observations without inventing extra factors (dark energy).

Wait until they find out that Dark Matter is is a similar aberration!
Self-importance and self-indulgence is the root of ALL evil.
