Physicists are asking: why has no one been killed by dark matter?


The fact that no one has died of being affected by dark matter is enough to rule out certain ideas about mysterious things, according to a new theory article.

There is a problem with which physicists face: most of the mass of the universe seems to lack, from observations of the structure of the universe, how galaxies and As they seem to distort distant light. Thousands of physicists are now looking for what these effects can produce. But the simple fact that we are living here on Earth can give you an idea of ​​what is dark matter, and the researchers behind the new document say that the human body itself can serve as a dark matter detector.

There are many candidates for dark matter, most of which have something in common: they feel the force of gravity, but they do not interact with other physical forces, such as electromagnetism. This means that, instead of "dark", it is better to think it as "invisible" or "transparent."

Scientists have spent many time and effort construction detectors to find this dark matter. Most of their experiments operate under the same strategy, which is to build an incredibly sensitive sensor, protect it from any potential source that can cause false positives and wait. The scientists of the last decade have been more interested in the idea of ​​WIMPs, or weak interactive massive particles, which could be around the size of the heaviest subatomic particles.

More recently, scientists from the United States Jagjit Singh Sidhu and Glenn Starkman, both from Case Western Reserve University and Robert J. Scherrer of Vanderbilt University, considered another class of macroscopic particles, or around or less massive than one being human But here is the thing: if this particle existed, and considering the amount of dark matter that we hope will be in the universe, this particle would have caused at some time a wound similar to the inexplicable firearm in a being human, according to the document. Posted to the arXiv physics preprint server.

Basically, this article only provides with a thought experiment something that other research has provided with a lot of expensive equipment: a restriction, which means a series of features that scientists should not disturb the search.

"It's good to be sure that we are fully aware of our most basic physical limitations, which include not breaking daily life," said Chanda Prescod-Weinstein, assistant professor of physics and astronomy at the University of New Hampshire. "This exemplifies one of the challenges faced by theoretical physicists at the time of imagining how to solve problems, such as finding an explanation for dark matter."

A physicist not involved in the study, James Beacham, particle physicist at the ATLAS experiment at the Large Hadron Collider of CERN, liked the studio, but did not think it was too much. You want to see the data that shows that there is actually no number of unexplained wounds similar to the firearms that occur around the world. "[A]By the end of the day, however, I believe that this document is fascinating because it is an example of how a null result – or something that seems to be a null result, such as the lack of dark matter of WIMP in our current experiments – can inspire people think of new ways, "he told Gizmodo in an email.

This is not the first time that scientists have considered the effect that dark matter could have on the human body. A 2012 document from Katherine Freese of the University of Michigan and Christopher Savage of the Nordic Institute of Theoretical Physics considered the evil that WIMP could have on humans and found that they would not be dangerous, or at least they would not be more worrisome than others. sources of daily exposure to radiation. Freese told Gizmodo that he had no complaints about the new job.

To be honest, perhaps there are more urgent questions, because we have not found any sign of dark matter yet and if that is because we are wrong with some element of the laws of physics. Ultimately, dark matter can not seem like the standard WIMP that scientists are currently looking for.

I guess there are ways to get worse than being struck by a dark matter group, especially if your death were to solve one of the greatest mysteries of physics. Hi, maybe they would call the particle after him.
