Bizarre 'Dark Fluid' With Negative Mass Could Dominate the Universe (theconversation.com)
One of the most galling mysteries in physics is that of the dark matter and dark energy. Scientists believe that together, these could account for up to 95 percent of the total mass in the universe. Now, a researcher at the University of Oxford says a new theory could explain all that "dark phenomena." From a report: The two mysterious dark substances can only be inferred from gravitational effects. Dark matter may be an invisible material, but it exerts a gravitational force on surrounding matter that we can measure. Dark energy is a repulsive force that makes the universe expand at an accelerating rate. The two have always been treated as separate phenomena. But my new study, published in Astronomy and Astrophysics, suggests they may both be part of the same strange concept -- a single, unified "dark fluid" of negative masses.
Negative masses are a hypothetical form of matter that would have a type of negative gravity -- repelling all other material around them. Unlike familiar positive mass matter, if a negative mass was pushed, it would accelerate towards you rather than away from you. Negative masses are not a new idea in cosmology. Just like normal matter, negative mass particles would become more spread out as the universe expands -- meaning that their repulsive force would become weaker over time. However, studies have shown that the force driving the accelerating expansion of the universe is relentlessly constant. This inconsistency has previously led researchers to abandon this idea. If a dark fluid exists, it should not thin out over time.
In the new study, I propose a modification to Einstein's theory of general relativity to allow negative masses to not only exist, but to be created continuously. "Matter creation" was already included in an early alternative theory to the Big Bang, known as the Steady State model. The main assumption was that (positive mass) matter was continuously created to replenish material as the universe expands. We now know from observational evidence that this is incorrect. However, that doesn't mean that negative mass matter can't be continuously created. I show that this assumed dark fluid is never spread too thinly. Instead it behaves exactly like dark energy.

I had the lamb vindaloo for lunch.
I want my negasphere!
Is it just me or has the physics community been grasping at straws lately?
Magic!
At what point do you admit that your theory is probably wrong?
Just NOPE. Dark fluid ... being magically replenished ... wrong answer to a rather complex question.
They need to explore / understand the fabric of space *itself*. It is stretchable. It can contract. It is also, itself, simply coming apart. If you try to measure this "coming apart" the problem (that I have) is that the measuring instrument itself is coming apart (expanding).
One day the cohesion of space itself will come to a breaking point (the end).
I can confirm it has a strong repulsive force

Am I alone in Iâ(TM)m getting tired of looking at comments because I donâ(TM)t want to sift through pages of creamer/apk/nazi/racist posts.
It wouldnâ(TM)t be so bad if these were original. Today it really looks like a few bits running and spamming every post.
I miss hot grits, Natalie Portman, Beowulf clusters of thingiemabobs and even the goatse man himself. Well, I donâ(TM)t miss him that much.
How did we go from meme to vile?
Step 1: Write a peer reviewed article challenging accepted cosmology. Leave open the option that it may be nonsense, so no one can say you're a total crackpot and can pass peer review.
Bonus step: resuscitate a long dead competitive cosmology model.
Step 2: Write an opinion piece to generate publicity and buzz for your crazy theoryle (helpful if on Slashdot).
Step 3: Sit back and watch the refutations publish over and over, thus generating citations for your article and increasing your H-Index.
Step 4: Leverage H-Index to qualify for further grant awards, thus pushing up your value to the University and increasing your salary. Profit!
My theory is debunked only if H-Index isn't the major factor in grant awards they way it is in the US; not sure about the UK. But honestly, this strikes me as being written because bad publicity is better than no publicity.
I need to get me some of that bizarre dark fluid with negative mass.
These aren't even trolls so much as sad autists. Spewing the same copy and pasted garbage in every post. The janitors who run the place can't figure out a simple filter for them. Or perhaps more likely they don't read the comments or even care.

While all the material we see in our universe is due to one big bang, my theory is that the larger universe of truly far away objects is the result of a collection of as many big bangs as there are stars. These big bangs are far enough away that they are unobservable (with current tech) and distributed in such a way that our observable material is pulled apart by them.
This has the benefit of explaining why our universe is accelerating outwards, and gets away with the fools assumption that the big bang is the one thing in the universe that is unique (hit anything that happens can happen over and over again. Additionally we have no need for some fancy jumping though hoops to explain why we cant see some dark matter that would have to comprise the vast majority of our IMMIDATE surroundings (on a astrophysics scale)
There it is, give me my Nobel prize. That darn Hawking stole my other one for his obvious theory that black holes decay (nothing lives forever)
However, that doesn't mean that negative mass matter can't be continuously created
and that's were I got lost. I fail to see how a theory can be dependent on something so fundamental, yet fail to account for it.
There is also the question of how a negative mass fluid would react with other n/mass fluid particles around it. If positive masses attract each other, and a positive-negative mass interaction results in repulsion, how would two negative-mass particles interact with each other?
politicians are like babies' nappies: they should both be changed regularly and for the same reasons
I modify your theory, implementing a non-linear distribution of spacetime curvature to account for the effect the, relatively weak, extra-universal bodies gravitational forces.
I'll take my prize winnings in bitcoin, please.
because math allows it. But not everything is real what math allows. Just look at the epic failure of SUSY or read "Lost in Math: How Beauty Leads Physics Astray" from theoretical physicist Sabine Hossenfelder.
"However, studies have shown that the force driving the accelerating expansion of the universe is relentlessly constant."
And there are several studies which claim that the accelerating expansion of the Universe is an illusion. I think it would be simpler(?) to explain the galactic rotation problem and/or the Bullet Cluster without dark matter with a model. And if that model also says something about the expansion of the Universe which matches the observations that would be an extra. But no model should be built upon solely on the accelerating expansion of the Universe.
"It therefore appears that a simple minus sign may solve one of the longest standing problems in physics."
I have read a study which claimed that the bending of light around a galaxy was consistent with the velocity of the stars around the galaxy. That means space-time is really curved with the right amount since there cannot be any repulsive force which bends light.

I can't wait to get a hold of some of this stuff. Just think of all of the applications. I'm going to compress it, remove the wheels from my kids skateboard and attach it to the bottom to make the first real hover-board. It should make jet packs a reality too. We shouldn't need as much thrust since it will only be needed for directional control. And just think of the applications for cars. using it to repel some of the mass away from the road will make the car more fuel efficient. And if traction is lost, you can simply pump the liquid to the top of the car to regain traction. I feel like it's the 1950's all over again. Nuclear powered vacuum cleaners, robot butlers, weather control and glass dome houses are coming. I'm sure this will make fusion viable in just 20 years too.
There is a Mexican mathematician by the name of Miguel Alcubierre who came out with description of a theoretical method of propelling a solid object in space at extremely high speeds.
https://en.wikipedia.org/wiki/...
His theory pencils out as internally consistent, but when you start to match it up the the observable universe, you get into things that we didn't think actually existed - like a requirement for a material with negative mass.
Fellow Slashdotters, I need a few hundred liters of this stuff for my DIY Alcubierre drive. Anybody got any advice on how I can collect a material that starts to run away faster and faster as I get closer and closer to it?
TIA!
There needs to be a lot more supporting stuff than a speculative idea. Show me an hour long lecture on YouTube outlining the supporting evidence.
Facts are history now plebs have politics for religion on social media.

I think maybe astrophysicists have been watching too many Marvel movies because what they're talking about is basically gravitonium.
0peeium in it (but spelled correctly) immediately deleted? As in, this is an 0peeium dream?
Dark matter is simply slightly phase shifted material from the multiverse. Each exhibits slight draws and faint interactions with each other. There is a ground breaking paper coming out in the next several months by one of my professors.
Sorry, Gravity doesn't exist.
"From the folks who brought you 'dark matter', then 'dark energy', we now have the all-new negative-mass Dark Fluid!
Yes, made just for those times when the math doesn't match natural observation, and creating a new class of matter or energy out of whole-cloth is more convenient than admitting your assumptions were incorrect, or your model is wrong!
Stay tuned for our next 'convenient discovery'; if you thought the notions of the aether and the earth riding on the back of a turtle were quaint, wait till you get a load of this!"
Easy Peasy
Get in front of it and have somebody else chase it towards you
you mean get in front of it and have someone with more mass than you chase it towards you.

Got some. Big puddle under my truck.
Have gnu, will travel.
I'm tired of you apple asshats who won't fix your goddamned keyboard!
Stuff like this article shows that we really have no idea how any of it works. Crazy theory gets published and the "researcher" becomes famous for a second. Maybe the scientists coming up with this stupid stuff should spend their time following the Kardashians and come up with theories about their next big project, while real scientist figure out the real solutions.
Give this press release a crackpot score. E.g.: 5 points for each mention of "Einstien", "Hawkins" or "Feynmann". So 20 points right there.
When all you have is a hammer, every problem starts to look like a thumb.
You dont mass if you got math. :)

If it's like a dog, the trick is to run away and it'll chase you. If it's like a cat, just open your laptop and you'll have more than you want in short order. Oh, hey, you can find plenty on Slashdot, so I guess it's like a cat.
The entire damn point of science is, that you do not have to believe.
You experience patterns in the input you receive, allowing you to predict y from x. And the more you see them, and the more specific they get, the more you can trust them to be reliable. That's literally all you will ever get.
Even peer review easily is a pseudo-scientific concept, if you don't have anything to trust in those peers themselves!
And the best over 9000 sigma study paper you will ever read, still will only be anecdotal evidence to you, unless you have either repeated it, or have somebody trustworthy who repeated it.
(But hey, we're permanently living based on anecdotal evidence. We don't do six sigma studies to check if that person we just met for the first time, actually exists. Let alone if we die when jumping off the 21st floor.)
Belief, on the other hand, is when you keep a viewpoint, regardless of (lack of) evidence or even contradictions.
That's why I cringe so much, every time I hear and American say "I believe in science!”.
I want to scream "NO. You haven't understood anything!!".
No advice on how to catch it, but I've seen this fluid lying all over the road on hot summer days. The faster you try to go toward it, the faster it goes away from you.
That one's pretty simple. Just make sure the mass is the same in any direction, and it will prefer to run into the center, where the repulsion is the smallest (locally).
You can even easily have it flow out, by opening a small hole for it to get out, and make a tube of mass for it to flow through.
Basically you can treat it nearly the same as normal matter under pressure, but using gravity instead of EM.
The universe is coated in a thick, viscous fluid - "God's Semen"!
I'm coming for you.
I'm glad they're finally starting to catch up
There is this retired cosmologist called Jean-Pierre Petit, who has been pushing such a model for years, with a few papers published in peer reviewed journals. His videos are very interesting for an introduction to cosmology. Some were translated in english.
Unlike familiar positive mass matter, if a negative mass was pushed, it would accelerate towards you rather than away from you.
I claim a patent on using this as the sleeve for sexbot robovaginas!

I think there's an Adam Ruins Everything episode on why we consider some drugs horrible, but others OK.
Like my date and her Coors.
Thank god for that.
Again, thank the gods.
Or at least since 1759 according to the website.
And one more time, thank the powers that be.
The Russians have won. They have made the world a cesspool of distrust, greed, fear and hate.
If the equations describe observable reality, use them.
It is more likely something simple, like matter and space being the same thing with one being able to convert into the other. Thus, with matter turning into its space equivalent, the farther out you look the more volume of included matter turning into space you have and so an acceleration away from the viewer. I have an intuitive feeling that space and matter equivalence explains a lot in Relativity and QM. 50 years?
E Proelio Veritas.
If you were willing to call the 'dark fluid' "time"...admitting that it is flowing outward from every point in space... and consider that gravity is just normal matter slowing the outward flow of time, creating what we perceive to be an attractive force, then, yes, that just might work.
theories are made to be broken.
Did you guys read the actual paper? It mentions no Coulomb law-type interactions whatsoever. "A unifying theory" without electomagnetism - so aggrav(it)ating!
Dark matter is considered to be "invisible" mass that makes galaxies behave the way they do by its gravitational effects. But the dark fluid stuff could be sitting between galaxies, and "push"/compress them via negative gravitation?
We all know black holes are absorbing matter but never release it (false, the Hawking radiation permit to information to be freed?).
What if black matter is just the matter absorbed by black holes and released by some way in that form?
Oh, please let them call it phlogiston!

aaand you are out.
A "dark fluid", with "negative mass", that needs to be "continuously created". This absolutely reeks of a mathematician wanking around in the dark, just throwing ideas at the wall and hoping something will stick.
Most of these ideas perish because there is no observational support for them, nor are they falsifiable. Lee Smolen has written about how the cosmology theorists are too far ahead of the observational scientists. Thus they can let their imaginations run wild without any significant reality check on those ideas.
Writing beautiful equations is one thing. Describing the universe is another. Unless you are willing and able to put your beautiful math to the test against observed reality, you are just wanking in the dark.
I need some "negative money" where the more I spend, the more I have!
How many times does this have to be repeated?
Random trivia fact: This is the core technology that the entire Mechwarrior / Battletech universe relies upon.
Replying to myself. Nevermind that's KF drives. I'm confusing myself, heh.
Actually, you've got it backwards.
The negative mass will chase you.
There's a nice set of diagrams early in the article that shows it.
Could have been reported 30 years ago but was to exotic to tolerate. It's actually a group of metals and we can make them.
