What is dark matter most likely?

Most dark matter is thought to be non-baryonic in nature; it may be composed of some as-yet-undiscovered subatomic particles. The primary candidate for dark matter is some new kind of elementary particle that has not yet been discovered, in particular, weakly interacting massive particles (WIMPs).

Is dark energy emitted by dark matter?

Reference Article: Facts about dark matter. Roughly 80\% of the mass of the universe is made up of material that scientists cannot directly observe. Known as dark matter, this bizarre ingredient does not emit light or energy.

What is dark matter how it can be detected?

We can detect the dark matter through gravitational lensing, which detects shifts in light produced by distant celestial objects [5]. The bright spots outside the colored areas are stars and galaxies that are not part of the Bullet Cluster (Credit: X-ray: NASA/CXC/CfA/ M.

How is dark matter detected quizlet?

Dark matter has been detected by carefully observing the gravitational effects on matter we can see in clusters of galaxies and in galaxies. Dark energy has been detected by observing the rate of expansion of the universe, from studies of white dwarf supernovae.

Can we see dark matter particles?

One of the oldest and biggest experiments hunting for dark matter particles, DAMA is alone in claiming to see them. It purports to pick up on rare interactions between the hypothesized particles and ordinary atoms.

Does Earth’s speed affect dark matter detectability?

Earth’s varying speed relative to the dark-matter-suffused galaxy should lead to changes in the amount of dark matter detected by the DAMA experiment.

What is the DAMA/LIBRA experiment?

The signal always peaks in June, when Earth is moving fastest through the dark-matter-filled galaxy, and troughs in December, when the planet curves into the leg of its orbit that opposes the sun’s motion around the galaxy, slowing us relative to the dark matter wind. The latest run of the experiment, called DAMA/LIBRA-phase 2, began in 2011.

What does an a technician do at DAMA?

A technician works on the detectors for the DAMA experiment, which uses 250 kilograms of sodium iodide in an attempt to find dark matter. Exactly in line with this hypothesis, the DAMA scientists find that nuclear activity in their crystals varies throughout the year.
