This would be so cool! Anytime they can find some new way of exploring the galaxy, the more it can tell us about life on our planet. Dark matter is such a cool, elusive part of the universe. We know it exists because of its effect – or lack thereof.
From the article: in the 30’s it was observed that “distant galaxies appeared to be spinning faster than their mass allowed. The observations led to the notion of dark matter, a material that neither emits nor absorbs light, but exerts an unseen gravitational pull on the galaxies it surrounds” Finding a direct link ‘close to home’ to dark matter could open up so much understanding about how our universe works!

Can we collect it and store it?

I skim the paper. I would not call it „direct“ evidence. Basically it is analyzing gamma radiation that may be consistent with annihilation of dark matter.
In addition, from the abstract, and I quote, „This cross section is larger than the upper limits from dwarf galaxies and the canonical thermal relic value, but considering various uncertainties, especially the density profile of the MW halo, the dark matter interpretation of the 20 GeV „Fermi halo“ remains feasible.“
This is basically science-speak for not really, but while improbable, it is not completely impossible. So I would really take this with a grain of salt.

Pff, you could find a lot of dark matter in the heart of republicans except, do they have hearts???

There is literally no reason to believe dark matter is the only possible source of these gamma rays.

This is a huge discovery. For the first time, dark matter can be seen by the gamma rays it emits when dark matter particles collide with each other. We no longer have to deduce the existence of dark matter based on its gravitational pull. We can now look for gamma rays and see dark matter.
>One of the many theories of dark matter postulates that it is made from so-called weakly interacting massive particles, or wimps, which are heavier than the protons found inside atoms, but barely interact with normal matter. When two wimps collide, they can annihilate one another, releasing other particles and a burst of gamma rays.
>To search for potential dark matter signals, Totani analysed data from Nasa’s Fermi Gamma-ray Space Telescope, which detects the most energetic photons in the electromagnetic spectrum. He spotted a pattern of gamma rays that appeared to match the shape of the dark matter halo that spreads out in a sphere from the heart of the galaxy.
>The signal “closely matches the properties of gamma-ray radiation predicted to be emitted by dark matter,” Totani told the Guardian.

Why can’t dark matter just be normal matter in another dimension. Why is it dark anyway?

I guess now it’s just regular old matter if we can see it

The Nibblonians had just finished eating.
