WebFeb 1, 2024 · About 95 percent of the mass of our galaxy is invisible and does not interact with light. It is made of a mysterious substance called dark matter, which has never been directly measured. Now, a new study calculates how dark matter’s gravity affects objects in our solar system, including spacecraft and distant comets.
WebWe know that dark matter exists because of the effect it has on objects that we can observe directly. Scientists study dark matter by looking at the effects it has on visible objects. … WebApr 13, 2024 · Although dark matter makes up a large chunk of the universe, approximately 85 percent, it has remained hard to detect because dark matter does not interact with light or other forms of electromagnetic radiation. Scientists believe …
WebAug 21, 2024 · Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object. Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. WebDetecting Dark Matter Evidence from the depths of the Universe has ruled out a number of models for what the mysterious dark matter might be, but one candidate that fits so far is the lightest supersymmetric particle (LSP) otherwise known as the “neutralino”, the lightest of a whole range of new particles suggested by a theory called supersymmetry.
