Dark matter machine- End of us all?

A machine to start operating next year might finally detect the “dark matter” that pervades every galaxy but that no one can seem to identify, a newly published paper claims.


Dark matter is thought to be a substance that reveals no trace of itself except through its gravitational pull on objects that are visible.

Calculations show that every galaxy floats at the center of a blob of dark matter, estimated to account for over 80 percent of each galaxy’s weight.

The researchers are placing some hopes in the Large Hadron Collider, a device due to switch on next year, to detect dark matter.

The machine would probe the structure of matter in unprecedented depth by smashing particles up to reveal what’s inside them.

The most powerful such instrument to date, the collider would crash subatomic particles together at 99.999999 percent the speed of light. Collisions so furious would recreate the energetic conditions prevailing a fraction of a second after the Big Bang explosion thought to have given birth to the universe.

There are several theories on what dark matter is. A leading proposal holds it consists of hypothetical particles called WIMPS, or Weakly Interacting Massive Particles. Physicists’ calculations suggest the Big Bang could have produced these in suitable numbers to form dark matter.

Scientists also believe the Large Hadron Collider—part of the Geneva-based laboratory of CERN, the European Organization for Nuclear Research—might be able to detect WIMPs. But this may be a long shot, since, as their name indicates, they’re “weakly interacting.” They interact little with other matter, including the stuff our detectors are made from.

No interaction means no detection.

But the physicists who offered the new proposal suggest dark matter might consist not of WIMPs, but particles called “SuperWIMPs”—the products that result when certain WIMPs decay, or fall apart.

The collider might be able to detect SuperWIMPs, said Jonathan Feng of the University of California, Irvine, a member of the research team. The group detailed the idea in the April 21 issue of the research journal Physical Review Letters.

These particles would be similar to neutrinos—ubiquitous but almost undetectable specks, trillions of which pass harmlessly through each of us each second. Because they also interact very weakly with matter, neutrinos slip through things leaving rarely a trace. As a result, physicists must build lake-sized detectors just to detect a handful yearly.

SuperWIMPS interact even more weakly than neutrinos, Feng said. This would make them, too, problematic to track down. But there’s a solution, according to Feng and his colleagues at Cornell University in Ithaca, N.Y. and the University of Arizona in Tucson, Ariz.

SuperWIMPs are decay products of a peculiar form of WIMPs that, unlike others, carry electrical charge. And colliders can easily detect charged particles. These particular specimens would “stick out like a sore thumb,” Feng wrote in an email. They “look like electrons”—charge-carrying entities in normal atoms, but are millions of times heavier.”

These progenitor particles are theorized to survive for between a few seconds and a few months before breaking down. If experimenters can catch them then, Feng and colleagues believe, the charged nuggets can be spirited somewhere where they can be observed more closely. The manner and timing of their eventual disintegration could reveal much about their SuperWIMP decay products.

Feng and colleagues have also theorized that the progenitors’ relatively slow decay should leave a distinct signature in the cosmic background radiation, a faint glow that permeates the universe.

Scientists believe that to observe this background radiation is to look at what could be called the surface of the Big Bang fireball—though the view is much distorted owing to a huge expansion of the cosmos during the 14 billion years or so since the light left that place.

Feng and colleagues argue that with appropriate instruments, the SuperWIMP signature in the background radiation is detectable.

A SuperWIMP discovery could also help explain gravity, if Feng’s group is correct. This is because these particles are likely to take the form of hypothetical entities called “gravitinos,” which are closely related to gravitons, particles that according to some speculative theories carry the force of gravity.

The supposed gravitino-graviton kinship is part of a theory known as supersymmetry, which predicts that each known particle has a massive, as-yet-unseen “superpartner.” This scheme allows for a one-to-one correspondence between two known families of particles: those that make up matter, such as the components of the atom; and those that transmit forces. The forces, in turn, control how the matter particles bunch up or otherwise interact.

In supersymmetry, gravitinos are superpartners of gravitons.

A SuperWIMP finding could moreover provide an entry point to test string theory—an also speculative set of proposals that seek to explain nature’s various forces as manifestations of a single, deeper force. Supersymmetry fits neatly into string theory, widely seen as scientists’ best shot for a “Theory of Everything.”

String theory also predicts exotic phenomena such as extra dimensions, and proposes to resolve discrepancies between the two most powerful fundamental theories of nature devised to date: Einstein’s General Relativity and quantum physics. The former applies to the universe on giant scales, and the latter to subatomic phenomena.

So “the discovery of dark matter in a collider,” Feng wrote in an email, would “show us how nature works on both the largest and smallest length scales.



What they do NOT tell you is that it can potentially KILL US ALL! Right where it reads " The most powerful such instrument to date, the collider would crash subatomic particles together at 99.999999 percent the speed of light. Collisions so furious would recreate the energetic conditions prevailing a fraction of a second after the Big Bang explosion thought to have given birth to the universe." The big bang was the biggest most power, energy?? In existence, And creating that in a matter of just 1 second one is simple outrageous! Maybe some of you will find this..stupid? But there is so many things that our own government(s) have not and will not tell us! For those of you interested google/wiki/youtube-Project Blue Beam. Also Watch zeit giest!.

I'm sorry if this troubles some of you, but hopefully this helps some of you in the process. Thank you for reading and post what you think! I highly recommend researching into these matters.

 

You do realize that this deals with sub-atomic particles, right? An atom's mass ranges from 1.67e-27 to 4.5e-25 kg, so the "big bang" they want to create would last less than half a second. They also shoot a certain number of particles at a time, so there is no real danger.

EDIT: I forgot to mention that they don't actually shoot the atoms together, but the particles that they are made of. E.g. Protons, electrons, etc. A proton's mass is roughly 1.67e-27 kg; it's diameter is roughly 10^-15 meters.

 

creating something so big would take an enormous amount of particles. Even if they can control how many they shoot it will not matter. Something that big still has a chance of destruction. Also, haven't you heard of the machine they created or "creating" to make mini black holes? This is huge, something like that can take us out in a second.

 

It isn't "so big." Like I said, it deals in the sub-atomic level. Yes I have heard of the machine, it is called the Large Hadron Collider. I also stated before that anything they create would disappear so fast because of the masses of the particles they are using.

Read this article, it's very informative.

 

Interesting indeed. I still believe it can cause something, maybe not the destruction, but something bad. Thank you for the info

 

Doesn't nibbler just shit this stuff out?

 

*waiting for sythe's response*

 

You must be retarded for believing in this shit.

Have you actually done your research? Do you have qualifications to show that you know your shit? I'm sure as hell the people that write these doomsday articles don't. Funnily enough, when people who do know their stuff speak up, everyone ignores them.
