"The signal measured by Dr. Totani seems to come from an area with a significantly higher WIMP density than would result from our early universe model and from what we observe in the cosmic microwave background. "

"One of the most serious theories speaks precisely of the WIMPs I mentioned earlier, which in Polish translation sometimes sounds amusingly like 'mięczaki' (softies/wimps). But this acronym means weakly interacting massive particles, which are precisely these weakly interacting, yet massive particles. "

"Dark matter is not just a theoretical whim of physicists, but an absolute foundation of our models of the universe, without which galaxies should simply fall apart. "

"Supersymmetry requires every type of particle to have an associated supersymmetric particle, called its superpartner. WIMPs are hypothetical particles... that interact only through the weak nuclear force and gravity. "

"In the case of dark matter annihilation, this energy escapes in the form of gamma radiation, at least it should. And gamma radiation is the most energetic form of light we know. "

"“We detected gamma rays with a photon energy of 20 gigaelectronvolts (or 20 billion electronvolts, an extremely large amount of energy) extending in a halolike structure toward the center of the Milky Way galaxy. ... Importantly, these gamma-ray measurements are not easily explained by other, more common astronomical phenomena or gamma-ray emissions.” "

"Rubin noticed that stars on the outskirts of galaxies orbit their centers just as fast as those near the center. "

"supersymmetry, which suggests that every known particle has a heavier partner, and WIMPs would be precisely such partners, heavy particles that react with almost nothing except gravity. "

"Vera Rubin noticed that stars on the outskirts of galaxies orbit their centers just as fast as those near the center. "

"In the case of light, when an object moves away from us, the light waves are stretched. A longer wave means a shift of the spectrum towards the color red. The redder a galaxy's light, the faster it speeds through space. "

"This signal comes from the halo of our galaxy and has a very specific energy that cannot be explained by ordinary astrophysical processes. "

"Its maximum is around 20 gigaelectronvolts, and a gigaelectronvolt is a unit of energy used by particle physicists. 1 GeV is roughly the energy equivalent to the mass of one proton at rest. "

"Budget 2027 has a 30 billion euro hole. PIT reform announced for January 2027, but no one knows what it will contain yet. "

"Lambda particles are unstable and decay quickly, but it was precisely the products of their decay that allowed researchers to reconstruct something extremely important, namely the spin of these particles. "

"During collisions in an accelerator, protons break apart, and the quarks they are made of are violently pulled away from each other. Between them, a high-energy string filled with a virtual menagerie is then formed. "

"Because their lifetime is infinitely short. Their mass and energy do not have to agree with what Einstein predicted. They are, as it were, outside the law, existing only as temporary field fluctuations. "

"These particles do not obey the required Einstein relationship between their energy, momentum and mass. E² = p²c² + m²c⁴. "

"In this particular experiment, physicists used proton collisions, which were accelerated to an energy of about 200 giga-electronvolts. "
