Explore further: Dark matter clusters could reveal nature of dark energyPosted on 12/05/2018 9:02:07 AM PST by ETL
Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses 'negative mass." If you were to push a negative mass, it would accelerate towards you. This astonishing new theory may also prove right a prediction that Einstein made 100 years ago.
Our current, widely recognised model of the Universe, called LambdaCDM, tells us nothing about what dark matter and dark energy are like physically. We only know about them because of the gravitational effects they have on other, observable matter.
This new model, published today in Astronomy and Astrophysics, by Dr. Jamie Farnes from the Oxford e-Research Centre, Department of Engineering Science, offers a new explanation. Dr. Farnes says: "We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of 'negative gravity," repelling all other material around them. Although this matter is peculiar to us, it suggests that our cosmos is symmetrical in both positive and negative qualities."
The existence of negative matter had previously been ruled out as it was thought this material would become less dense as the Universe expands, which runs contrary to our observations that show dark energy does not thin out over time. However, Dr. Farnes' research applies a 'creation tensor," which allows for negative masses to be continuously created. It demonstrates that when more and more negative masses are continually bursting into existence, this negative mass fluid does not dilute during the expansion of the cosmos. In fact, the fluid appears to be identical to dark energy.
Dr. Farnes's theory also provides the first correct predictions of the behaviour of dark matter halos. Most galaxies are rotating so rapidly they should be tearing themselves apart, which suggests that an invisible 'halo' of dark matter must be holding them together. The new research published today features a computer simulation of the properties of negative mass, which predicts the formation of dark matter halos just like the ones inferred by observations using modern radio telescopes.
Albert Einstein provided the first hint of the dark universe exactly 100 years ago, when he discovered a parameter in his equations known as the 'cosmological constant," which we now know to be synonymous with dark energy. Einstein famously called the cosmological constant his 'biggest blunder," although modern astrophysical observations prove that it is a real phenomenon. In notes dating back to 1918, Einstein described his cosmological constant, writing that 'a modification of the theory is required such that "empty space" takes the role of gravitating negative masses which are distributed all over the interstellar space." It is therefore possible that Einstein himself predicted a negative-mass-filled universe.
Dr. Farnes says: "Previous approaches to combining dark energy and dark matter have attempted to modify Einstein's theory of general relativity, which has turned out to be incredibly challenging. This new approach takes two old ideas that are known to be compatible with Einstein's theory—negative masses and matter creation—and combines them together.
"The outcome seems rather beautiful: dark energy and dark matter can be unified into a single substance, with both effects being simply explainable as positive mass matter surfing on a sea of negative masses."
Proof of Dr. Farnes's theory will come from tests performed with a cutting-edge radio telescope known as the Square Kilometre Array (SKA), an international endeavour to build the world's largest telescope in which the University of Oxford is collaborating.
Dr. Farnes adds: "There are still many theoretical issues and computational simulations to work through, and LambdaCDM has a nearly 30 year head start, but I'm looking forward to seeing whether this new extended version of LambdaCDM can accurately match other observational evidence of our cosmology. If real, it would suggest that the missing 95% of the cosmos had an aesthetic solution: we had forgotten to include a simple minus sign."

Bizarre 'dark fluid' with negative mass could dominate the universe – what my research suggests

“There would be quantum virtual particles popping into and out of existence.”
And dogs and cats living together!
However, the theory is not nearly as weird as it may sound. Turns out that we cannot account for some very major observations given the physics as we know it. But, perhaps we should discount this because according to progressives, “the science is settled”. (Note: that’ll never be spoken by a true scientist. One only hears it from science illiterates such as the MSM and politicians.)
I’ll look in the garage. There’s a lot of stuff out there.
Let me know if you find my sock.
If dark matter and dark energy are so weird,
why is dark chocolate so good?
“I think the steady state model predates the big bang model.”

Yup, it does. For a long time it was thought that things were pretty much they way they’d always been cosmos-wise. Then the Big Bang came along and blew the old notion up.
There was a time when a scientist would have realized that if his solution required negative mass, it was literal nonsense.
Today you get millions in grant money for it.
I’ll bet The Little Dog took it!
He was running around with a sock this morning!
Was it a black sock?
Wait a minute.
My left foot is kind of cold.
Never mind.
It was my sock.
The filthy little sock snatcher.

I need to understand the implications of negative mass further to accept this theory. The main problem is that negative mass matter would be able to exceed the speed of light based on Einstein’s special relativity equations and we have never observed any such phenomena. Violating the light constant velocity would also undermine the core concept of causality between fundamental particles and forces in the universe. Break out the hyperdrives and time machines. I’ll wait for the confirmation before I get too attached to this idea.
Yes, he outlines some of the history of the ideas here:
Lol! THat about sums up our understanding of fundamental reality.
Interesting thought experiment. I’m going to hatch that on some of the kids in my Troop.
In Tesla’s day it was still ‘ether’.
The article describes what is called:
a fluid [ether?] which possesses 'negative mass."
IMO, for waves to exist, there must be a medium for the waves to travel through. Otherwise a photon transitioning from particle state in the vacuum of space to a wave state in a glass lens, would loose its wave shifted origin.
Are we back to a type of 'ether', now called "a fluid" in this new theory?
It may not be possible to remove all the energy from space.
“space-time” might not exist without the energy of the vacuum (quantum field).
Negative mass is a nonsense concept. The implication of it is that we have abandoned all reason and logic whatsoever by taking it seriously, and are now saying whatever it takes to get the next grant.
Could potentially explain the "negative gravity-like" force causing the universe to accelerate in its expansion. Can't rule out anything too quickly.
There isn't much that's actually new here, and most of it has been speculated about in the context of General Relativity for a long time. The real question is whether vacuum exerts zero, positive (pressure) or negative (attraction).
That can be done in the Einstein Field Equations without the "negative mass" taking on the same significance as the ordinary, inertial mass which cannot exceed the speed of light.
