Dark matter has been sleeping scientists for decades. Although it occurs commonly in the Universe, we have not yet been able to detect the particles that make it up. But this may change soon.
At least such plans have German scientists from the Max Planck Institute streamingaudit. Their analysis of dark matter data obtained over the years and computer simulations allowed them to present a new candidate responsible for the essence of dark matter. The super-heavy gravitino is expected to have a mass of 0.02 milligrams, or as much as a flea egg. It doesn’t seem like much, but we are talking about particles here, which means that it is as much as 10 quintillions times more mass than the mass of a proton or neutron.
Gravitino is to be a unique particle of its kind, which not only interacts with ordinary matter by gravity, but also electromagnetically. Although this first assumption is nothing new, the second one is quite a bold move on the part of the Germans, because if the particle interacted electromagnetically with matter, we could find signs of it even on Earth.
Scientists intend to turn our planet into one large particle detector and use its 4.5 billion years of evolution and interaction with hypothetical particles to ultimately detect them. Gravitino particles, interacting with electromagnetic forces with ordinary matter, must leave traces of ionization, e.g. in rocks, as defects in crystalline structures. The ambitious goal set by the Germans will not be easy to achieve, but the latest technology advances should help in this. We keep our fingers crossed.
