Galaxies whirl faster than they are supposed to. Space is expanding when it shouldn’t. What’s more, it’s all starting to feel like we’re forever going in the dark with regards to the big unanswered questions in physics. One physicist’s answer lies in a speculative ‘ dark fluid’ with negative mass. No, such a material has never been seen previously. In any case, the chase for intriguing particles and energies is getting harder constantly, so it’s worth keeping the choices open.
Jamie Farnes from the University of Oxford proposes we turn to Einstein’s theory of general relativity – the one that portrays gravity in terms of space-time geometry – and change it a little so it permits matter with negative mass to fly into reality. This development of a bizarre ‘pushing’ molecule could settle two of material science’s most baffling secrets – why do galaxies hold together as they spin? What’s more, for what reason does the Universe appear to grow so rapidly today contrasted with the past?
At the present time, the best clarification for every observation is that difficult to-see stuff is doing a great deal of pushing or pulling.
Dark Matter and Dark Energy
Dark matter is whatever happens to be in charge of ‘pulling’ together stars and galaxies notwithstanding all that we can see. It’s more than likely some sort of huge particle that doesn’t collaborate well with the visible matter, making it more imperceptible. Dark energy, then again, is a hypothetical phenomenon in charge of balancing gravitational forces, causing large-scale structures to separate and making the Universe resemble it’s expanding at an ever-increasing rate.
At the present time, they’re the best answers we have. While there are a lot of proposals concerning what lies behind every one of them, we’re still little closer to a smoking gun. That is notwithstanding the fact the two combine to make up approximately 95 percent of all the energy and matter in the cosmos. Farnes thinks about whether this dark 95 percent all comes down to a similar thing. He’s proposed an all-penetrating dark ‘fluid’ that shows up in empty space and weakly pushes against the surrounding matter.
In addition to the fact that this would delicately nudge drive galaxies apart, making extra space for more dark fluid to ‘pop’ into reality, however, it would likewise push in on their stars, preventing them from freeing as the galaxy spins. To the extent potential hypotheses go, it feels rather miserly. Nothing quite like a two-at the-cost of-one solution. Even better, Farnes’ negative mass models could be put under serious scrutiny using information on the distribution of galaxies gathered using the Square Kilometer Array.
“The result appears to be somewhat beautiful,” says Farnes.
“Dark energy and dark matter can be bound together into a single substance, with the two impacts being just logical as positive mass matter surfing on an ocean of negative masses.”
Beautiful, beyond any doubt.
Be that as it may, even Farnes concurs the idea is somewhat out there to the extent the supporting physics goes. Above all else, while there are wonders that exhibit negative mass-like attributes, they’re not the same thing as spontaneously appearing negative mass particles. Furthermore – while quantum mechanics does predict particles popping in and out through existence in a vacuum – this additionally doesn’t indicate the interminable generation of a dark soup of negative masses.
All things considered, before we lose track of what’s most important, Albert Einstein himself proposed a comparative fudge factor as he portrayed out general relativity. So there’s room in the mathematics to represent such a concept.
