The black thing is a true neck pain.
The term black object itself refers to a hypothetical substance as often as the universe speaks through gravity and service as screff of galaxies and other many structures. The real particles in the dark thing have haven’t been found yetHowever – despite decades of effort to discover it. Some critics such as the concept seems to be a factor that causes physics used in their incomplete theories of the universe. But if darkness is something “true” or helpful fruit of the imaginations of odists, there is simple evidence that wants to lose the problem.
Call it what you want, There is a clear thing to be strange happening in the universe. Stars outside the galaxies of galaxy very quickly. Galaxies Buzz around the clusters that are so strong. Strands-rich strands at cosmic web coalesce just easy. And there are more examples.

Every attempt to change the dark matter in the basement of discards physics ideas, such as Change the energy of gravity To accommodate all the relevant observation quirks, fail-hard. While it is impossible to rule such strategies – you don’t know what a skilled theorist can cook tomorrow – a half century with satisfactory fruit.
Decades of evidence of many rules clear candidates For the darkest thing motivated by high-energy physics. But high-energy physics are not the only game in town. There are other fields, including the condensed physics of the matter, the beach branch that examines the assets of many object collections, such as how all atoms in a spice glass. This field of physics has its own odd corners, such as The wonderful world of superconductivity. And these corners are different enough to give some useful inspiration for understanding the puzzle of the dark matter.

Per line of scores of cosmological inquiry in humility knowing that Just a slim part of this thing in the universe light. After the centuries of effort, developing the TABLE TIMETHE particle zooTHE Standard model of partikt physicsThe forces of nature and all the rest, we now know that we are not shaved in the face.
But science is a journey only for those who are humble, so there is only one choice before us: until.
We have many strong tools that we handed over our journeys through the dark corners of the universe. A tool is our suite of observations, measures made by scales from the cosmic galactic consisting of the width of the universe and at a deeper time. All of these observations announced, and finally judge, any theory of the candidate. We may be in the dark about the dark thing is, But we have a very good feeling what it is ba. If you have your own idea to explain the dark matter, then it should come by crucible of onctvations inact. If an idea fails wherever, we will continue and try next.
Another powerful tool is physics itself, our exploration of mathematics in the world. We do not fully understand the dark, the identity or attitudes or interviews with the rest of the universe. But we know, in different degrees of trust, what is left in the universe. The dark as a lost piece of a puzzle; We don’t know what’s the piece, but we almost know the form that needs to be done.
Any darkest thing, it has to follow the laws of physics (even if we have not yet known all laws).
For example, if the universe does not have one minute, the darkest thing should have something to be set from the normal object (a process called “froze as if we came to our preceding candidate for the dark thing, the wimpor weakly associated with massive fragment. We have some hypothetical particles made by physics theories that, if they are active and abundant and generally around the universe, there is naturally done exactly that.
but We have never met a wimpand it is Theoretical underpinnings are shown in thin ice.
So we’re going on.
There is also the axionanother hypothetical fragment from high-energy physics and one trillion hours more than wimp. If the axion exists and have the right assets, it will also, can do all the things we know we need the Dark Dail.
But we still have to see an axion directly-however, to be fair, we do not seek the axions nearly as we want in wimps, just because Wimps are thought to be a shoo-in for the dark matter.
So we’re going on.
In May Guanming Liang and Robert Caldwell, in Dartmouth College, published a paper on Physical Review Letters where they offer their own candidate for the dark matter. A pessimist can look at this study and wipe their eyes:
That answer can be fair. This model is probably – no, almost sure – wrong. But that’s because most models are wrong most of the time. If we know the response ahead, we don’t have to do science. We can only find the correct answer by moving all the mistakes, taking wheat from the chaff, try again until we are worthy.
But we just know when we try.
And the real struggle, Liang and Caldwell’s model not only try but try something real NEW. Instead of encouraging from high-energy physics, with hypothetical particles derived from it or that exotic interview, the authors look at the nature of physics.
In a regular conductor, electricities lead to electricity, but they also offer resistance. Below enough temperature and proper materials, however, the electrons condension-or, if you want,arranging themselves in pairs to a lower energy configuration. It eliminates electric resistance and makes the magic of superconductivity occurring.
By analogy, Liang and Caldwell model looks into the dark thing as a soup of exotic particles born moments after Big Bangin odd times before proton and neutrons arrive. This soup does not interact with the normal matter but also does not have any self-mass. As the cosmos broadened and cooled, the particles of dark things moved and clumped up, forming many blind evolutions, from the remainder of the universe other than their influence on the universe.
Calculations are complicated and tentative but promise. The main advantage of this method is that a new mechanism is allowed to make the darkest object in the same conditions in the same steps that are unreliable in wimp. And this model does not simply change the existing evolution object. If exotic particles have some Mass, then only some of them break the dark thing. Others can be locked in place as a background that sounds in the universetendency to play on paper in black energyThe mysterious force showing that facilitates the expansion of the universe. Fix this model, Dark Energy may vary in timethat aligns with Tentative results Exit Galaxy reviews.
Studies like this is the only first step: a plusibility check to get the right amount of the dark thing at the right time. It still remains to see if it can know for the perfect rural evidence that is in the darkest thing we recognize the cosmos in the cosmos in the universe?
And can this last try everything? Can this predict in the existence of a fragment – or a drop leaking in the dark matter – that someday we see directly see for ourselves?
The search for the real nature of the dark matter is very disappointing because those who sweep any model should be clear, to say the least. We don’t believe in this model, or any other hypothesis, until it succeeds where many failed.
So we’re going on.
