What is dark matter made of


“A SIMP is really similar to particles we have seen already,” says Murayama. Prior to structure formation, the Dark matter provides a solution to this problem because it is unaffected by radiation.
To hold the elements of the universe together, dark matter must make up approximately 80% percent of the universe. SIMPs, on the other hand, are composite particles, made of other, smaller particles. Just like dark energy, we don’t know a whole lot about dark matter. Cham Ghag, a physicist at University College London and collaborator on LUX, said in a statement.

Additional data from other observing projects or direct-detection experiments would be required to validate the interpretation.Although dark matter makes up most of the matter of the universe, it only makes up about a quarter of the universe's total composition. The best-known theories of this class are A problem with alternative hypotheses is observational evidence for dark matter comes from so many independent approaches (see the "observational evidence" section above). It’s a hypothesized new type, or flavor, of neutrino. Four images are visible in a circle surrounding the lens; a fifth is visible near the centre of the picture.Composite image showing the galaxy cluster 1E0657-56, the Bullet cluster.

For their part, Van de Water and colleagues have started a fresh experiment at Los Alamos, called Coherent CAPTAIN-Mills. This dark matter must exist if the motions of stars and galaxies are to be understood, but it has not been observed through radiation of any kind. By contrast, dark matter cannot lose energy by emitting light. Dark matter could be made of one kind of particle or many.

Astronomers All of these methods provide a strong indication that most of the matter in the universe is something yet unseen.Although dark matter is different from ordinary matter, there are a number of experiments working to detect the unusual material. "A new phase in the race to detect dark matter with ultra-low background massive detectors on Earth has just began with XENON1T," project spokesperson Elena Aprile, a professor at Columbia University, said in a "Though a positive signal would have been welcome, nature was not so kind!" This would change the …
