The theory speculates that if a certain type of dark matter exists, it would occasionally kill people. Such a dark matter particle would pass by men like a bullet, a new study claimed. But since no one died from such unexplained guns like wounds, this type of dark matter doesn't exist. There are other ways to recognize these types of dark issues, and researchers should look further, says Catherine University of Texas professor, who was not involved in the study.
She said: "We do not know what a dark matter is, so we should not abolish the things."
Dark matter is about 85 percent of the mass of the universe, but the substance itself remains a puzzle.
One theory suggests dark matter consists of weekly interaction of massive particles.
The particles would be abundant, but not capable of interacting with regular issues that only very sensitive detectors would be able to detect – until now without success.
A less mainstream dark matter candidate, known as macros, would form heavier particles.

Though macros would be much rarer than their rival candidate, no collisions with common cause would be violent, and they would be obvious.
And a groundbreaking new study explores what the traces might resemble if people encounter the macros particles.
Dr Glen Starkman and Cleveland Westhawk Singh Sidhu, theoretical physicist at the West Bank University West School, Ohio, have originally sought traces of Macros in Granit slabs, when the college professor Robert Sharpener said: "Why can't you use it?" Only a detector?
"The energies you are talking about, the things probably had a best man, and worst of all, killing a man."

The team forged ahead with the idea and modeled macros that would have a similar effect to a fatal shot from a .22 caliber gun.
Such particles would be miniscule, but very heavy, thus releasing the same amount of energy as a sphere when passing through a human.
Their calculations focused on millions of people living in Canada, the United States and Western Europe in the last decade, as these countries have reliable data from death.
In this sample, scientists would expect to see a handful of reports of unexplained deaths of invisible dark matter "bullets."

The deaths would not go unnoticed – they would allow victims to die or die with a tubular wound where their flesh was wounded.
The experiment does not preclude heavy macro-dark matter, Professor Shearer says. It only eliminates a certain range of them.
Heavy macro dark matter would not often suffice to measure, free notes and other forms would not kill people.
"There is probably still room for very dark matter," said Paolo Gorla, a particle physicist in Italy's underground Gran Sasso National Laboratory, who is not involved in the study.
