Dark matter could be destroying itself inside the bellies of exoplanets

"But an even more reliable method would be to search for large numbers of exoplanets throughout the Milky Way and make a map of their temperatures, Smirnov said. Dark matter is expected to pile up in the galactic center, so this map should show exoplanet temperatures rising slightly as you look closer to the Milky Way's core."

A potentially testable model prediction here. Constraints are needed on all dark matter models and verification standards too in my opinion. A work in progress it seems.

Because dark matter (DM) does not interact with electromagnetic energy, it can pass right through normal matter. However, because it does have gravitational attraction with ordinary matter, it will be drawn into massive normal matter objects like stars and planets. Over the 4 billion years of our solar system, our sun and planets should have captured a lot of DM. That includes our earth. There should be a massive DM "dark earth" coinciding with our planet. It should be contributing substantially to the mass of the earth. That means that a lot of the mass that produces our gravity is NOT ordinary matter, but DM. Does the dark earth have something to do with the occasional flipping of the earth's magnetic poles as the dark earth rotates independently? What could seismic waves tell us about the amount of DM under our feet? Since there is more DM in the universe than regular matter, if there is NOT a lot of DM captured in our sun and planets, what is preventing it? Could DM tell us what happened to the antimatter that should balance all the regular matter in the universe?
