Dark matter is not known to interact with ordinary baryonic matter and radiation except through gravity, making it difficult to detect in the laboratory. The most prevalent explanation is that dark matter is some as-yet-undiscovered subatomic particle , such as either weakly interacting massive particles (WIMPs) or axions . [ 12 ]
Direct detection of dark matter is the science of attempting to directly measure dark matter collisions in Earth-based experiments. Modern astrophysical measurements, such as from the cosmic microwave background , strongly indicate that 85% of the matter content of the universe is unaccounted for. [ 1 ]
The Large Underground Xenon experiment (LUX) aimed to directly detect weakly interacting massive particle (WIMP) dark matter interactions with ordinary matter on Earth. . Despite the wealth of (gravitational) evidence supporting the existence of non-baryonic dark matter in the Universe, [1] dark matter particles in our galaxy have never been directly detected in an expe
Collisionless: Dark matter particles interact with each other and other particles only through gravity and possibly the weak force; Dark matter constitutes about 26.5% [11] of the mass–energy density of the universe.
Gravitational wave astronomy helps understand the early universe, test theories of gravity, and reveal the distribution of dark matter and dark energy. Particularly, it can help find the Hubble constant, which tells about the rate of accelerated expansion of the universe. All of these open doors to a physics beyond the Standard Model (BSM).
The new analysis widened the scope. "Our DESI data shows that it is in agreement with Einstein's theory of gravity but still favors a dynamical dark energy - and finding these simultaneously is ...
The equivalence between gravitational and inertial effects does not constitute a complete theory of gravity. When it comes to explaining gravity near our own location on the Earth's surface, noting that our reference frame is not in free fall, so that fictitious forces are to be expected, provides a suitable explanation. But a freely falling ...
Indirect detection relies on the products of dark matter interactions. Thus, there are several different models of dark matter interactions to consider. Dark matter (DM) is often considered stable, as a lifetime greater than the age of the universe is required ( yrs) for large amounts of DM to be present today. [1]
