'Gravity portals' could morph dark matter into ordinary matter, astrophysicists propose
By Paul Sutter - Astrophysicist
Astrophysicists have an idea that could help to solve two mysteries: the reason for the bizarre abundance of super-high-energy radiation shooting from the center of our galaxy and the identity of invisible stuff called dark matter that has perplexed the world since its discovery some 50 years ago.
And the idea has a super-cool name: gravity portals. The idea goes, when two dark matter particles (whatever they are) get sucked into one of these portals, they obliterate each other and spit out shockingly strong gamma rays.
This line of thinking can potentially explain why the galactic center — where dense clusters of dark matter are thought to lurk — is full of gamma rays; and it could shed light on how the dark matter behaves and might occasionally interact with the normal matter of our universe.
I especially like the closing paragraph of this article …
Yes, this idea is a stretch. But given that physicists are in the dark when it comes to the identity of dark matter, new ideas are always welcome. And this theory was specifically designed to match the observation of the gamma rays. But once that doorway has been opened, allowing dark matter particles to transform into regular matter (leptons, in this case), more theoretical work can be done to see if there are other ways to test the theory.
And that last line means LOTS more $$$$$$$ which means new houses, cars, vacations etc, etc, etc.
So of course these physicists won't give up on gnomes .
Plus look at all the cool and fascinating ARTWORK they get to stick in their articles.
Just saying ...
