The most powerful cosmic rays in the universe start the earth shockingly close, paper claims

The most powerful cosmic rays that rain on earth cannot come from distant corners of the universe, but from heavy dark matter particles that are destroyed in our own garden.

Cosmic rays are high -energy particles that constantly flock through the cosmos. Most of them consist of protons, but can occasionally consist of the cores of heavy elements such as helium and even iron. Although they are microscopic, grab a blow. Everyone almost travels Speed of lightAnd the fastest energies have trillion times more than our most powerful particle accelerators.

Astrophysicists understand the origins of most cosmic rays. Every time there is an energetic event in the universe, a shower of cosmic rays will probably be created. This can include supernovas, the fusion of stars and the matter that is swallowed by Black holes.

But we do not understand the origins of the most powerful cosmic rays. The problem is that these sources, although there are many energetic sources for them, are billions of light years away. These matching particles cannot hike these major distances without significantly slowing down. Maybe their origins are much closer to the home.

And maybe their origins are much more exotic than a mere cosmic explosion. In A current newspaper This has not yet been checked by experts, a Russian astrophysicist suggests that the most powerful cosmic rays come from an exotic form of dark matter.

Heavy, dark and self -destructive

The dark matter The particle itself would be very difficult – far heavier than the hardest known particle, the top curd. This particle of dark matter, known as a scalaron, would have been created in the earliest moments of cosmic history during an era known as inflation when the universe grew up many orders of magnitude at an moment.

Since then, the scalaron has remained largely in the background, since it is invisible to light and only influences the rest of the universe through its gravitational influence. But very, very rarely, two scalarones can overlap – and announce each other in an energy. This flash can include extremely energetic cosmic rays.

Scalarones are everywhere so that you can produce ultra-hoch-energy cosmic rays in our own galaxy. But here funny ideas have to fulfill the reality of observation. If the scalarons cross too often, they produce more cosmic rays with energy -pantry than we observe. Conversely, if you do not overlap and annihilize yourself often enough, it will not match known observations.

It is simply that it is possible that the scalarons are responsible for the number of cosmic cosmie ray recognitions that we have. The density and interaction frequencies correspond to the well-known behavior of dark matter.

However, this is a weak hypothesis. The production of scalarons in the early universe requires adjustments to Einstein Theory of general theory of relativity This may not be considered further examination. And there are competing proposals to explain the highest cosmic rays. For example, they can be produced in molecular clouds in our own galaxy without the need for dark matter.

Nevertheless, it is an interesting idea and it shows how the extremes of our universe can be used as a test bed for radical ideas. By continuing to follow these ideas, we can find other ways to test them observant. And if this idea works, it not only gives us a window in dark matter, but also the early universe itself.
