Dark matter is more than five times as abundant as all the visible matter in the universe. So why can't we see any of it?
Can dark matter be converted to dark energy the same way normal matter is converted to energy? What is the evidence of dark matter and dark energy? How do we measure Dark Matter? Why does the photon behave as its own antiparticle?. Based on the observational evidence, is it possible that...
Antimatter is a type of matter that is made up of different subatomic particles than normal matter. The particles that make up antimatter are: positrons, anti-protons, and anti-neutrons.Answer and Explanation: We don't know what dark matter is or even if it exists at all. Therefore, we...
The existence ofdark matter particlesthat gravitate but do not significantly take part in the three fundamental forces of thestandard model of particle physics(which mathematically describes the “normal matter”) is fundamentally the basis, the central pillar, of thecurrently standard model of cosmolog...
To explain why the total energy in the universe consists of 5% of the normal matter (matter consisting of atoms), 27% of the dark matter, and 68% of the dark energy.SOLUTION: In the field of the big bang, 4.559×10atoms were produced. The dark energy is the energy of black holes....
1.6 Cold and warm dark matter WIMPs as described above are actually subsets of a larger astronomical class of cold dark matter (CDM) candidates. The most important property of CDM is that it is produced in the early universe with velocity low enough that it does not impact the formation of...
Limits are set on dark matter particle production in the context of simplified models with vector, axial-vector, scalar, and pseudoscalar mediators, as well as on a two-Higgs-doublet model with an additional pseudoscalar mediator. In addition, limits are provided for spin-dependent and spin-...
Dark matter density refers to the amount of dark matter present in a given volume of space, such as a cubic meter, typically measured in GeV/cm^3. It plays a crucial role in direct detection experiments by influencing the interactions of dark matter particles with standard matter. AI generate...
据日媒报道,日本一家出版社本月27日宣布,将出版理化学研究所前研究员、STAP细胞论文作者小保方晴子(32岁)的手记。 日媒称,这将是小保方在离职之后首次完整地向外界坦露心迹。据出版社方面介绍,手记名为《那一天》,共253页,28日起将在书店上架。 据悉,该手记由15个章节组成,记载了小保方从立志成为科研人员到201...
As seen, the scalar dark matter observables are governed by the dark matter mass m H1 and the new Higgs portals, given through the new Higgs masses and couplings, that connect the dark sector to the normal sector. Additionally, the masses of all such dark matter and new Higgs particles ...
