And the Fermi Space Telescope, just before I back up here a little bit, is dark matter. Just an explanation here about dark matter. It's the mass or matter in the universe. It's the largest portion of all matter that's in the universe, but it's undetectable. It's undetected, at least not directly. Indirect detection of it is possible. But, they're looking for it, and the main reason they're looking for it is because the universe is held together. All the galaxies, planets and that, they're all held in an orbit, they're all held together without flying apart. Because of some force bearing down on them, there's not enough matter in the universe to create the gravity that's required to keep everything running the way it is. keep galaxies all together, keep the stars within the galaxies and the planets orbiting the stars within that galaxy. So there has to be some other gravitational influence there. So that points to whether they refer to dark matter. Dark matter doesn't interact with regular matter so it's undetectable. You couldn't set up a direct experiment for it because it doesn't interact with anything that materially that we're familiar with. So the only way and detect this indirectly. Well, the Fermi Space Telescope, this studies high-energy wavelengths of gamma rays and it's detected emissions at our galaxy's center that may be associated with an arc matter particle. This is published in the Journal of Cosmology and Astroparticle Physics. This was on November 25th.
